Blueberry Baked Oatmeal
Healthy baked oatmeal naturally sweetened with maple syrup or honey! Change the fruit according to the seasons. Make some now for the rest of the week!
Updated by Kathryne Taylor on August 29, 2024
Spring is passing me by. I’m so utterly immersed in projects for my cookbook that I’m nearly missing the magnolias blooming outside. Fortunately, my dog Cookie always reminds me to slow down for a minute.
She starts pouncing on me every evening as the sun goes down, in her persistent, borderline desperate, but always cute sort of way. “Hey! Hey hey hey! Hello in there! Let’s go outside!” She gets her walk, and I catch some blooms as the sun sets.
I’ve also been forgetting to eat breakfast, which is a dangerous game. I got a big slap on the wrist for it last week, when I was photographing food and had to pause and sit down for a while. Shaky, lightheaded, sweaty—hypoglycemia symptoms are not cute, and never welcome. It was a reminder that I really have to eat well. We all do, or it will catch up with us eventually. My symptoms just come on sooner than most.
That’s why I started cooking in the first place. I couldn’t afford to eat out for every meal, but I had to eat well. So, naturally, I had to learn how to cook. I cook with wholesome ingredients, so I’m properly fueled for my days. Then, I find greater purpose in sharing those recipes with you all.
I feel good about sharing recipes that make me feel good. As a reminder to eat breakfast, I made some blueberry baked oatmeal for the week.
Healthy Baked Oatmeal Notes & Tips
This baked oatmeal recipe is loaded with wholesome ingredients—oats, nuts, maple syrup and blueberries. A couple of eggs bind it all together, and a light drizzle of butter on top makes it taste like a treat.
This baked oatmeal keeps me full all morning long, especially when I serve it with a big dollop of Greek yogurt.
Change It Up
I loved it as written below, but the recipe is highly adaptable. I used frozen blueberries (right from the bag), but you can use any fruit you’d like. You could also change up the nuts and spices, though you can’t go wrong with the recipe’s combination of cinnamon, nutmeg and vanilla.
I think an apple version would be great in the fall, and raspberry-banana might be fun with cashews and coconut milk in the summer.
Please let me know how you like this recipe in the comments. I hope it becomes a staple in your kitchen, too!

Blueberry Baked Oatmeal
This naturally sweetened baked oatmeal recipe features blueberries (or any fruit you’d like), wholesome oats, nuts and warming spices. You can bake some now and enjoy oatmeal for the rest of the week! Recipe yields 6 to 8 servings.
Ingredients
- ⅔ cup roughly chopped pecans
- 2 cups old-fashioned oats
- 2 teaspoons ground cinnamon
- 1 teaspoon baking powder
- ¾ teaspoon fine-grain sea salt (or ½ teaspoon regular table salt)
- ¼ teaspoon ground nutmeg
- 1 ¾ cups milk of choice (almond milk, coconut milk, oat milk or cow’s milk all work)
- ⅓ cup maple syrup or honey
- 2 large eggs or flax eggs
- 3 tablespoons melted unsalted butter or coconut oil, divided
- 2 teaspoons vanilla extract
- 12 ounces or 1 pint fresh or frozen blueberries (or 2 ½ cups of your preferred berry/fruit, chopped into ½” pieces if necessary), divided
- 2 teaspoons raw sugar (optional)
- Optional toppings for serving: plain/vanilla yogurt or whipped cream, additional maple syrup or honey for drizzling, and/or additional fresh fruit
Instructions
- Preheat the oven to 375 degrees. Grease a 9-inch square baking dish. Once the oven has finished preheating, pour the nuts onto a rimmed baking sheet. Toast for 4 to 5 minutes, until fragrant.
- In a medium mixing bowl, combine the oats, toasted nuts, cinnamon, baking powder, salt and nutmeg. Whisk to combine.
- In a smaller mixing bowl, combine the milk, maple syrup or honey, egg, half of the butter or coconut oil, and vanilla. Whisk until blended. (If you used coconut oil and it solidified in contact with the cold ingredients, briefly microwave the bowl in 30-second increments, just until the coconut oil melts again.)
- Reserve about ½ cup of the berries for topping the baked oatmeal, then arrange the remaining berries evenly over the bottom of the baking dish (no need to defrost frozen fruit first). Cover the fruit with the dry oat mixture, then drizzle the wet ingredients over the oats. Wiggle the baking dish to make sure the milk moves down through the oats, then gently pat down any dry oats resting on top.
- Scatter the remaining berries across the top. Sprinkle some raw sugar on top if you’d like some extra sweetness and crunch.
- Bake for 42 to 45 minutes (if using frozen berries, 45 to 50 minutes), until the top is nice and golden. Remove your baked oatmeal from the oven and let it cool for a few minutes. Drizzle the remaining melted butter on the top before serving.
- Serve as-is or with toppings of your choice. I prefer this baked oatmeal served warm, but it is also good at room temperature or chilled. This oatmeal keeps well in the refrigerator, covered, for 4 to 5 days. If desired, simply reheat individual portions in the microwave before serving.

Absolutely delicious! Turned out beautifully and I’ve shared it with friends and family. It was recommended to me by a dietitian.
Perfect breakfast as I batch cook for the week ahead.
Can I use quick oats instead? I have a ton here and regular oatmeal is getting kinda boring
Hi Dani, I don’t find quick oats work as well here. Sorry!
I just used quick oats and it’s delicious
I’ve tried to half this recipe many times but it ends up burning. I used an 8×8 square pan. I also use my toaster oven which worked perfectly for the whole recipe. Any ideas why this is happening when I half it?
Hi, those are usually convection ovens which cook differently and usually quicker. I hope you try it again! You will likely need less time.
You are using half the ingredients but your 8×8 pan is not half the size of a 9×9 pan. Therefore, your mixture is spread thinner than the original recipe and cooks quicker. For half a recipe you need a pan that has an area of approximately 40” or make 3/4 of the recipe for an 8” square pan.
Hi Kate
I felt this was a bit dense and I also saw parts of the egg cooked so I’m wondering if I didn’t whisk enough or maybe cooked too long?
Hi Kerry, I’m sorry to hear that! Did you fully blend your wet ingredients?
Hello,
I love your site…it’s my go to for many recipes.
Made this and ended up using pineapple as I realized last minute I was out of blueberries.
However, I found this recipe salty.
I think next time I will not add the salt, or just use 1/4 tsp.
I agree! I love this recipe and make it almost weekly but I cur the salt down to 1/4 tsp too. It was way too salty with 1/2 tsp!
Salt is not needed in this or many other recipes, esp. for those of us who are salt sensitive. Cut it back or eliminate it. Otherwise, good recipe with options, thanks!
If you use salted butter, omit the salt in the recipe..
I love this recipe and my family does too (adults, tweens and toddlers)! I have made it several times. I’ve made adjustments from time to time, depending on who I was serving it to (left out the nuts, or less nutmeg for me). It reheats well the next few days and it’s a good, filling breakfast. Thank you for this dish !
You’re welcome, Wendy!
Mine turned out a little too wet throughout (will see how it reheats) next time I want to omit all fruit and just serve it with a side of fresh fruit. Flavor is great though! Looking forward to trying it again
Thank you for sharing, Carissa!
Hi, I wanted to tell you how much I love this recipe – have made it three times in the past two weeks! It’s perfect for a make ahead breakfast. Plenty of protein with the nuts and milk and eggs. I also added a mashed banana the last two times I made this (only because I didn’t want them to go to waste). Please keep up the great work – love your recipes!
Thank you, Jenn! I’m glad you did. I appreciate you sharing.
This recipe is delicious! I added 2T chia, used coconut milk and call else the same. It will become a regular at my house! Thank you!
Same here. Worst soggy bottom I’ve ever seen, and I held back some of the liquid mix because it looked way too wet. Inedible, sad to say. I might have let it sit too long before putting into the oven. Might try again as the flavor was good, but will reduce the liquid drastically and use just enough to hydrate the oats.
ps – tried reheating, but all I got was burnt mush instead of plain old mush.
Hi DG, I’m sorry to hear that. What type of oven do you use?
Gas. Don’t recall if I used convection or not, but I might have mis-measured the oats or liquid. The mix was really soupy. What is the texture supposed to be like?
I’ve made baked oatmeal recipes in the past but this was far-and-away the best one I’ve tried. It’s a perfect blend of flavor and textures. Not sure where all the “overly salty” reviews are coming from, but I couldn’t disagree more. Perfect as is.
I’m glad you think so, Robert! I appreciate your review.
Way too salty! Why wouldn’t you mix the dry and wet ingredients before putting them in the pan. That just makes since. Salt and finer ingredients fall to the bottom of the bowl through the oatmeal. I would change this recipe that is posted so people stop not liking it.
I’m sorry you didn’t love this one, Laura. I appreciate your feedback. I have made it both ways and retested it and just didn’t have the same experience.
Sooooo salty. Incredibly disappointing. would prob be good with less salt, the texture was great!
I’m sorry to hear that. You can cut back on the salt next time.
This looks wonderful! I’m wondering if I can put it all together the night before, put it in the frig overnight and bake it in the morning?
Hi Stacey, I don’t recommend letting this sit overnight. The oats will soak up all the liquid and it won’t quite bake up the same. You could try mixing wet & dry and keep it separate until you are ready to bake. Let me know if you try it!
I made this for a party so assembled it the night before (along with a strata). Clearly I didn’t read the comments ahead of time… but it actually was delicious and turned out great!
Does anyone happen to know how many points this would be for one serving, made with the recipe as is?
I made this for the first time today. I wanted to prep ahead of time so I mixed all of the dry ingredients together, and all of the wet ingredients and stored separately in the fridge until time to bake. Turned out well! Thanks for another healthy and delicious recipe!
Great to hear, Eviedish! Thank you for your review.
Making th..is for the 2nd time with a large can of apples a handful of pecans, dates chopped and a handful of deciccated coconut. Beaut recipe for this Aussie senior as we eat this over 4 days. Thanks for the great recipe Kate.
You’re welcome, Chris! I’m glad you enjoy it.
HUGE HIT! Made this for me and my toddler. He gobbled it up. Read reviews and decreased salt to 1/4 tsp. Let it rest for a while after baking and it set it perfectly. Seemed too wet at first, but it just needed to cool! This will be in our breakfast rotation. Love all your baked recipes!
That’s great to hear, Liz! Thank you for you review.
SO delicious!! This is going straight into the rotation!!
This oatmeal was absolutely delicious! Tonight I doubled the recipe and used a 9×13 pan and it baked up beautifully. I’m usually sensitive to salty food and can taste it right away if it’s salted too much. My husband and I didn’t find this to be salty at all. I made the recipe as is and wouldn’t change one thing, well…maybe might have to triple next time since my kids all ate seconds. Thank you for your website! I frequent your site very often and I’ve never ran into a recipe I don’t care for. Great work, Kate!
Great to hear! I’m happy you and your husband both enjoyed it, Charlotte.
Hi! I doubled this recipe this morning and was wondering how long you baked it for? Thanks!
Hi Kate, how long did you end up baking it for?
Unfortunately I don’t remember how long I baked it for. My oven tends to run 5-10 degrees cooler so it’s hard to say.
This is a great recipe! Topped it with lemon greek yogurt and it was fab!
Very easy to get creative with! (Added PB2, dried mixed berries and a sprinkle of dark chocolate chips.)
I want more oatmeal in my diet and am trying to decrease my sweets so I am going to have a pan of this around consistently for a treat to start and end my day!
Sounds delicious! Thanks for sharing how you made it.
Absolutely love this recipe! I have used the original recipe multiple times in the past year but, recently have had to change my diet due to health issues so I can’t have any egg or flax. Instead I used a gelatin egg and it worked great! (Also I only use 1/4 tsp of salt)
Delicious recipe and a fantastic way to prep your breakfast ahead. It feels like having a cake for breakfast :P I love how versatile it is and I look forward to trying it out with different fruit and topping combos. Thank you! :)
You’re welcome, Kamila! I appreciate your review.
Can this be frozen and then thawed out and baked later?
Hi Joe, I haven’t tried it so I can’t say for sure. I’m not sure how well it will hold up.
Hi! I live in high elevation (Colorado). How would you alter your recipe to compensate? Thanks :)
Hi Mrs. Price. I’m not sure without trying it. Sorry!
So good! Was skeptical about the nutmeg but followed the recipe anyway and the nutmeg worked so well in it. I made half the recipe, then panicked when it was in the oven because I realized I forgot to halve the frozen blueberries, but it was still to die for, in fact I will do the same next time. No issues at all with saltiness or sogginess as I’ve read in a lot of comments – was perfect. Love that it’s not so sweet, great for breakfast. Baked for 45 minutes in 9×9 pan and used Himalayan pink salt. Will most definitely make again. Thank you!
You’re welcome! I’m excited you plan to make it again.
This has become a weekly breakfast in our house. We made some changes: used walnuts instead of pecans, frozen mixed berries, and orange or lavender honey. Then served with Greek yogurt drizzled with honey. Amazing!!!
Thank you for sharing, Bren!
I just wanted to say this is my go-to recipe. I use all kids of fruit and added seasonings but wet to dry ratio is always perfect! My fave is apple or pear with walnuts but I’ve done berries, shredded carrot and all work. I’m going to try a chocolate one next!
That’s great to hear, Jacqueline! I appreciate your review.
This is my go to recipe for baked oatmeal. I LOVE IT! I sometimes leave it in the oven a little longer to make it firmer. Then I cut it in bite sized pieces and separate in small containers for a quick snack. I also add chia seeds.
Absolutely LOVED this recipe. Going to be making it often this summer to meal prep for a week of breakfast. I made it with fresh rhubarb out of my garden and it was amazing.
Wonderful, Jessica! Thank you for sharing.
Loved this recipie. Always looking for simple breakfast ideas to feed the kids with on hand ingredients, and with dairy goats I’m always looking to add milk to breakfast! Works good with goat’s milk and both chicken or turkey eggs when I have extra turkey eggs I’m not incubating. Just about any in season fruit is usable, which is very homesteader friendly. I don’t find it too salty.
Thank you!
Love this recipe! I have made other oatmeal bakes and felt they used way too much sugar so I.checked out your site and sure enough I found this recipe. I’ve made it for company several times and it’s always a hit, and ppl ask for recipe. Love to make it up and have it for the week. The spices give it a lot of flavor. Big fan of your recipes. Thanks
Theresa
Wonderful to hear, Theresa! I appreciate your review.
It was good but, it was a little low in sweetness.
I’m happy you enjoyed it, Marisa! Thank you for your review.
It’s super good also you don’t need to follow the measurements as much I literally poured the oats in and the vanilla eggs if you want one more go for it just get the general measurements I doubled it but didn’t add nuts or nutmeg since I’m the only one who likes it in my family you can add chocolate chips and bananas also I sprinkled brown sugar on top turned out lovely you can also freeze it lasts a lot longer you can reheat or just it eat cold
Way too salty!!! …. Please please do not put recommended salt . Lacking in sweetness as well…. Looks delish but ingredients were not adequate :(
I appreciate the recipe
Hi Amanda, I’m sorry to hear that. Thank you for your review.
Really wanted to love this recipe because I love oatmeal. Followed everything to a T except omitted the cinnamon (son hates cinnamon). I used fresh blueberries, peaches and apple for the fruit portion. It tastes just, well blah. Maybe it was too warm? Will the flavors enhance as it cools? I won’t let it go to waste, but will not make again.
I’m sorry you didn’t love it, Kris. Leaving out the cinnamon impacted it since it’s a flavor component. Also, mixing those types of fruit could have impacted it too. Thank you for sharing your input.
This recipe is wonderful. It absolutely irks me to see these negative reviews from people who didn’t even follow the recipe. I’m sorry, but if you switch the fruit and omit other ingredients then you aren’t baking the recipe…
I’m delighted it turned out so well for you, Mallory! I appreciate your review.
Hi,
Can this be made with gluten free oats? I need to make it a gluten free recipe.
Thanks!
Yes, that will work well.
I make this on Sunday so I have breakfast for the week. Love it warmed up with Greek yogurt on top. Great meal to offer neighbors who may be older or need some help with food.
Wonder if it would freeze well?
I believe others have froze this and didn’t mind the results. But, it does make great leftovers for a few days as well.
Super good! I added a layer of sliced banana under the blueberries and loved it.
Great to hear, Lauren! I appreciate your review.
This was delicious! I didn’t have any nutmeg but it was still good, I also did half butter and half coconut oil.
Can this be made the night before and baked in the morning?
Hi Kelli, I wouldn’t recommend it. This does make great leftovers!
This recipe turned out great! I usually use kosher salt in cooking and baking, and this amount was perfect for me. I love that this recipe is really adaptable to what I have at home (swap nuts, fruits, etc). I used brown sugar instead of honey or maple syrup just because it’s more cost effective for me, and it turned out beautifully! It is a super easy make ahead breakfast that keeps me full until lunch! Thank you!
You’re welcome, Brooke! Thank you for your review.
Delicious! My mother-in-law made this for us a few weeks ago to reheat during the week. We served it warm with vanilla greek yogurt on top, so good! I immediately asked for the recipe and have made it on Sundays the past few weeks. Reheats beautifully for a quick weekday breakfast.
So delicious! Thank you, look forward to having it for the week.
My sister made this and shared it with me! One of the best things I have ever eaten! The texture reminded me of old-fashioned bread pudding which I love! I will be making this in the future!
That’s great to hear, Rhonda! I appreciate your review.
This was SO delicious. Next time i would definitely mix the wet and the dry together, rather than do the pour over, as the baking powder/salt mixture seemed to be a little potent (maybe i didn’t whisk it well enough in itself!) but anyway. Super delicious!
Thank you for sharing your experience, Larisa. I appreciate your feedback.
This was amazing. I felt like I was eating dessert for breakfast with no guilt! I shared with my mom and sister and they loved it too!
Wonderful to hear, Laurie! I appreciate you sharing.
I doubled the recipe and baked in a larger pan (10×14). It was very dry. The flavors were there, but were overpowered by the texture. Recommendation for next time? More liquid? Shorter bake time? Or? Thx
Hi Val, I’m sorry to hear that. Was it spread out too much? Maybe a little less time next time and then adjust bake time to desired texture.
Cut down sugar to 1/4 tsp per comments. AMAZING!!! I appreciate the tips on freezing/refrigerating for storage, this simply won’t last long enough to make it into the fridge lol. I’m genuinely surprised at how great it tastes without all the sugar. Thanks so much for this recipe!
I’m happy you found the comments helpful and were able to enjoy this recipe, Lena. Thank you for your review.
Wonderful recipe. It is on my breakfast meal prep because it is healthy and reheats great. Thank you.
My sister sent me this recipe and I’ve made it 3 times in the last 2 weeks, slightly altering with the fruit – first with frozen blueberries, then with a mix of fresh strawberries and strawberry jam, and then today with brown sugar and raisins. It’s a perfect breakfast to have on hand as a new mom and reheats in the microwave really well! Aside from the fruit swaps, I followed the recipe as written (minus the nuts, because I just kept forgetting to pick them up at the store) and found the flavors to be perfect, not too salty as others have said. This is going to be one of those recipes I will make for a long time! I can’t wait to continue to try new fruits – so far each variation has been delicious!!
I love to hear that, Kelsey! Thank you for taking the time to review.
My friend made this recipe with quick-cook steel cut oats and we all loved it! I wanted to try it but only have normal steel cut oats – any recommendations?
Hi! I wouldn’t recommend it with this one. I do love my Apple Steel-Cut Oatmeal if you are looking for a steel cut oat recipe.
Well, that turned out darned delicious! Subbed walnuts for pecans because that’s what I had on hand, and used one egg and one flax egg since that was my last egg. Ha! I seem to rarely have everything, but having substitutions available in the recipe is so helpful!
This was amazing! It definitely had more flavor than I was expecting! My 6 year old even scarfed it down quickly–100% will be making this again!
I left out the butter/oil completely, used agave in place of honey/maple syrup and used flax eggs (5T water mixed with 2T ground flax= the 2 eggs). Also used plant milk and certified GF oats because my son has celiac.
Thank you for sharing how you made this, Emmalee!
Mine was salty in patches, fine elsewhere. I believe mixing the salt into the wet ingredients rather than the dry Will allow it to dissolve and distribute better, and will solve the problem. This is a great recipe!
My favorite breakfast! ….and after gym snack, afternoon snack when I feel peckish……..an all round delicious recipe!
Thank you!
Love to hear that, Toni! I appreciate you taking the time to review.
Absolutely delicious!! I made with coconut milk and butter option and the drizzled butter at the end when serving is a MUST! Super satisfying!! Thank you and God bless!
I’m glad you enjoyed it, Julie! I appreciate your review.
