Baked oatmeal is one of our family’s favorite breakfasts. I try to make a pan every week, especially during the winter months when we are craving something hot that will warm us up. Oatmeal always hits the spot and keeps our bellies full until lunch time.
I love mixing up our baked oatmeal flavors and this Blueberry Maple Baked Oatmeal is perfection. The oatmeal is packed with juicy blueberries, lots of cinnamon, and sweetened with pure maple syrup.
How to Make Baked Oatmeal
- Preheat the oven to 350 degrees F. Grease an 8×8-inch baking pan with nonstick cooking spray and set aside.
- In a large bowl, mix together the oats, cinnamon, baking powder, and salt. Make sure you use old-fashioned oats and not quick oats.
- In a medium bowl, whisk together the milk, pure maple syrup, melted butter, egg, and vanilla. Pour the wet ingredients over the oat mixture and stir until combined. Gently fold in 1 cup of the blueberries. You can use fresh or frozen blueberries, both work great.
- Pour the mixture into the prepared pan. Sprinkle the remaining blueberries and chopped nuts on top of the oats, if using. Pecans, almonds, walnuts, and candied pecans are all great options. The nuts give the baked oatmeal a nice crunch and I love the extra kick of protein and healthy fats.
- Bake for 40 minutes, until the top is golden and oatmeal is set. Let cool for 5 minutes before serving.
- If you need the oatmeal to be gluten-free, you can use gluten-free oats. If you need the recipe to be vegan, you can use a flax egg and melted coconut oil instead of butter.
How to Store
Leftover baked oatmeal will keep in the refrigerator for up to one week. So you can bake it the night before or even several nights before so breakfast is easy on the morning.
To store baked oatmeal, let the oatmeal cool to room temperature and then place in an air tight container and place in the fridge.
And trust me, you will want to have leftovers because having baked oatmeal in the fridge is a breakfast lifesaver on busy mornings. This recipe doubles easily, just use a 9×13-inch pan and double all of the ingredients.
How to Reheat
To reheat baked oatmeal, add your desired amount to a microwave safe bowl and add a little splash of milk. Reheat until heated through, about 45 to 60 seconds. You can top your oatmeal with an extra drizzle of maple syrup if you want a little extra sweetness.

Can you use frozen blueberries with this recipe?
Yes! See the post for tips!
Does this recipe freeze well? This sounds amazing for postpartum. And it might be easier than making a ton of muffins.
Yes, you can freeze it! Add a splash of milk when reheating to bring it back to life:)
Could you make with Steel cut?
I tried this with steel cut oats and reduce the amount of oats to 1 cup. I also added 5 minutes to the baking time. Worked Great!
Just made this recipe this morning! Turned out awesome! I used coconut milk & coconut oil. Warm & delicious breakfast! Thanks for the great recipe.
Glad you loved the baked oatmeal. Thanks for letting us know!
Can I double and use a 9×13 pan?
Yes! Just double the recipe!
Its’ in the oven now, and I’ll let you know how it turns out!
I hope you love it!
I would like to make this. I’ve got your white chili and pumpkin pie already in progress! I only have quick oats I think. Will it be completely ruined if I used quick oats? Thanks!
I haven’t tried it with quick oats, the texture will be a little different and you might need a little more.
So you think I could make it the night before and bake in the morning?
I don’t eat too much oatmeal but that’s about to change. Just Wonderful! Love this fruit and nut oatmeal!!! Almost tastes like bread pudding. I never leave reviews but had to for this. Just dropped cinnamon to 1 teaspoon.
I made this last night, the smell was incredible, and it turned out wonderful. I’m not a big fan of oatmeal, but the combination of all the ingredients plus the blueberries is just delicious.
I used regular milk and honey,worked perfect.
This was easy to make and so delicious!!! We warmed up the leftovers throughout the week for a quick hot breakfast and it was just as good as the first time. It would be great to make when you have overnight guests.
I would love to make this ahead for a crowd – shall I pre-prepare it the night before and cook it in the morning? Or cook it the night before and rehearse it in the oven? If the latter, how long shall I reheat it for?
I would cook and reheat. You can reheat at 300 until warmed through, probably 20 minutes or so.
I meant REHEAT it in the oven – not rehearse!! ♀️
Was never a huge oatmeal fan until I tried this today! Wow, it was amazing and super easy!!
Great wholesome recipe that combines two of my favorite things! Thanks for the recipe!
You are welcome! It’s our favorite!
I add a whole chopped apple along with the 1.5 cups of blueberries, I add 1/2 cups of unsweetened coconut, 1/2 cup of chopped walnuts and increase the milk because I use Sukrin (brown sugar substitute) in place of maple syrup due to my spouse’s diabetes. I serve it with a topping of Greek yogurt or Skyr (Icelanding high protein yogurt), more fresh berries and a drizzle of sugar-free pancake syrup. Delicious
Love your adaptations! Thanks for sharing!
It is in the oven now. Do you think it would be still delicious if I wrap it up and take it to work in the morning?
Yes, you can reheat and eat all week! Enjoy!
This was wonderful, I made it last night to last me through the week! I used oat milk because that’s all I had and although it came out tasting wonderful, it was kind of crumbly and didn’t stay in bars like how its pictured; could it be because the butter may not have cooled completely?
Did you bake it long enough?
What modifications would you make for frozen berries?
Thanks!
You can use frozen berries. Use the same amount.
I make this at least twice a month as written and it’s fabulous every time. This time I substituted diced apples for the blueberries, apple pie spice for the cinnamon, and added some maple extract. Delicious in any season!
I have made this twice. First time I incorrectly used quick oats and fresh blueberries. Followed the recipe and baking instructions. Turned out mushy. This time I used old fashioned oats and frozen blueberries. Baked for 40 minutes and let it cool. Still mushy. What am I doing wrong?
It shouldn’t be mushy, but oatmeal isn’t firm. It still has an “oatmeal” texture. If you want it dryer, you can bake for longer or use less liquid, but I like the recipe as written.
Made the baked blueberry oatmeal this morning, added 1 T of dried orange zest..perfection! Only challenge is to not eat it all day, breakfast, lunch and dinner! Will be trying different fruit /nut combinations soon.
Just made this receipt this morning. It was delicious and very easy to make. I used 1% milk. Thanks for the great recipe!
Love it
I love this recipe! It’s delicious, easy to make, and perfect for meal prep.
If using frozen blueberries, do you thaw first?
Thanks!
I loved it. Made per recipe.
I only have the quick oats. Can I still use them and what would need to be modified?
I haven’t tried the recipe with quick oats. I am sure you can use them, but the texture will be different.
This dish is so tasty. Followed it exactly as written and it turned out great. Everyone loved it!
Yay! It’s a favorite at our house!
Hi – my children can’t stand blueberries – can you recommend a substitute, please?
You can use raspberries or blackberries. Or you can use dried cranberries or raisins.
I made this with apples instead of blueberries so good. Thank you for all your good recipes.
I eat this every day for breakfast. I add about 1/2 cup more blueberries. I have shared the receipt with a bunch of friends and everyone loves it. Easy to make and so delicious! One friend leaves out the butter to save some calories. I have made it without the butter and its just as good.
I am so glad you love the recipe!
Can the butter be subbed with applesauce or banana to reduce the fat? Can I sub egg white for whole egg? Thank you!
I have tried it with coconut oil instead of butter, but I haven’t left it out completely. I am sure you could use banana or applesauce but the texture might be a little different. Egg whites are fine.
This was amazing!! I made a half-batch and it baked really well. I was doubtful because the batter is so thin, but it turned out delicious. Thank you!
I normally use water when I make my morning oatmeal.. Can I do same for this recipe?
Sure, the flavor will be a little different.
One of my favorite breakfasts! So easy and comes out perfect every time.
Yay!
I have all the ingredients to make this tomorrow.
If I were to put this into 1/2 cup glass jars, how long should i bake it?
Would It be possible to substitute and egg white for a regular egg?
Sure, just use 2 egg whites for 1 egg.
I have made this so many times now. I’ve never been a breakfast person. When I make this recipe, I wake up thinking about having it with my coffee. I recently started a diet (noom) and have really cut out sugar. Today is the first time I made this since starting the diet. I think I can cut the maple syrup in half and still have enough sweetness to make it taste great. Living in Vermont, maple syrup is a staple and I love finding ways to use it. Thanks for sharing this delicious recipe.
Easy and yummy!!
A favorite at our house!
I made this for my elderly in-laws so they could have a hot breakfast. They had it for several meals and loved it. I didn’t change a thing and it was perfect. Thank you for another great recipe!
Tried making this dish. The flavour is out of this world… but the texture is very soggy… not sure where we went “wrong”
Made this today and am in love! The flavor is divine! Your picture looks like it’s a cake like, solid texture but mine is super moist and on the soggy side. It sort of holds the shape when cut, but yours looks drier. I wonder if I should have baked it longer, or if my butter wasn’t quite cool enough. Either way, I will give it another go for sure! So good – thank you!
You can bake it longer next time if you want it more firm.
OMG I forgot how much I love this recipe!!! I just started making it again a few weeks ago. It is so easy to make and then you have breakfast for the week. I leave it the refrigerator and take a piece and microwave it in the morning. I use unsweetened almond milk, add extra blueberries and do not add the butter.
A staple at our house.
This recipe is so delicious!! Love an easy meal prep breakfast.
I think I over mixed though, as it turned out very tough. Any suggestions of how to soften it? Maybe pouring some milk on top and let sit in the fridge?
You can try adding more milk to soften the oats.
This is a great recipe that I love to make for my family. We all love you, Maria! Thank you!
Thanks:)
