If you are looking for an amazing time saving breakfast recipe then I’ve got the perfect post for you in the form of this baked blueberry oatmeal. Nutritious and filling this is the perfect family breakfast and can be made ahead of time.

Baked oatmeal is basically oats cooked with milk and a few other kitchen pantry items in the oven. Baking the oatmeal creates a chewy soft casserole-like dish that’s full of breakfast goodness. It’s made by combining all the ingredients together and baking in the oven – a healthy, convenient meal that is highly adaptable and nutritious!

Ingredients

  • Blueberries: You can use fresh or frozen blueberries. They are a great source of vitamin C and antioxidants and are so yummy!
  • Oats: Use old fashioned oats for this baked oatmeal. Check that they are gluten-free certified if you are intolerant.
  • Pecans: I like to add nuts to add texture.
  • Cinnamon: A little cinnamon adds a nice sweetness and the flavor works so well with the blueberries.
  • Baking powder: This helps to lighten the blueberry oatmeal so that it is not too stodgy.
  • Salt: Salt helps to bring out the natural sweetness of the blueberries.
  • Milk: I made this oatmeal with almond milk to keep this dairy-free and vegan. You can make this with other plant based or dairy milk.
  • Maple syrup: To naturally sweeten. You can also use honey.
  • Flaxseed: I like to add flaxseed to my oatmeal for some healthy omega-3s.
  • Coconut oil: To help bind the ingredients together.
  • Vanilla extract: For sweetness and flavor.

How to make blueberry baked oatmeal

Start with the dry ingredients in a bowl and stir to combine. That includes the old fashioned rolled oats, baking powder, salt, cinnamon and pecans. You can use other nuts instead of pecans, like walnuts or almonds.

Next, combine the milk, flaxseeds, maple syrup and melted coconut oil in a small bowl. Then pour the wet mixture over the dry ingredients and stir to combine.

Next, grease an oven-safe baking dish with coconut oil, place half the blueberries on the bottom of the dish, and then pour the oats batter on top. Sprinkle more blueberries on top before baking.

Now you’re ready to bake the oatmeal in the oven. It will take about 35-40 minutes, and you’ll know it’s done when the blueberries and oats soften, and the oats become golden in color. I divide the 8×11 baking dish into 6 servings, but it can easily serve 8 people.

Recipe Variations

This recipe is highly adaptable with many kitchen staples! Here are some ways to switch it up that work really well.

  • Change the fruit: The blueberry can easily be swapped for other fruits like strawberries, apples or peaches. You can even do half blueberries and half bananas if you’d like. Also, if you only have frozen fruit, that works well, and there’s no need to thaw it in advance.
  • Change the nuts: Instead of pecans, try it with walnuts, almonds, hazelnuts, pistachios or cashews. It’s a good idea to chop the nuts, so they blend well with the other ingredients.
  • Change (omit) the sweetener: I only use a little maple syrup to offset the tartness of the blueberries, but you can swap it out for honey, agave syrup, brown sugar or stevia. If you’re using sweeter fruits like bananas or peaches, for example, you can leave out the sweetener all together.

Tips for making this recipe

  1. Don’t use quick oats. Quick oats are chopped into finer pieces, which makes them faster to cook. Although they taste the same as rolled oats, the texture of quick oats is much finer, so they soak up more moisture and can dry out the baked oatmeal.
  2. Do not mix the oats with milk ahead of time. If you want to prep the recipe halfway before baking, you can mix the wet ingredients in one bowl and the dry ingredients in another bowl. Just don’t combine them until you’re ready to bake. Otherwise the oats will soak up all the liquid and yield a dry texture.
  3. Keep liquid ingredients at room temperature before combining. If the milk and maple syrup are cold, the melted coconut oil will solidify when it comes in contact with them. Having the ingredients at room temperature helps with the blending process. If the coconut oil still solidifies, just microwave the combined wet ingredients for 15-30 seconds until the coconut oil melts again.
  4. Double the recipe for a bigger crowd. If you double the recipe, use a large baking dish and just add 10 minutes to the baking time.

Frequently asked questions

Can I use frozen blueberries?

Yes, this baked blueberry oatmeal works really well with frozen blueberries. There’s no need to thaw the blueberries in advance. Doing so may turn the whole dish to a purple color as the thawed blueberries mix with the liquid.

How long can I store the baked blueberry oatmeal?

The oatmeal is great for meal prepping. Store it in an airtight container in the refrigerator for up to 5 days. Then you can reheat individuals portions in the microwave for 30-45 seconds before serving.

Can I freeze the baked oatmeal?

Yes, the baked oatmeal freezes really well. Allow it to cool completely, then store in individual portions in freezer-safe bags or containers. Reheat individual portions with a tablespoon of water or milk before serving.

This baked oatmeal is a perfect make-head breakfast that the whole family will enjoy. You can double the recipe for a larger crowd or for breakfast throughout the week. Leftovers taste just as good reheated and topped with a dollop of coconut yogurt and maple syrup. Baking oatmeal gives it a chewy soft texture that is so warm and satisfying in the morning!

  1. I’m 8+ months pregnant so I’ve been looking for and testing frozen meal prep recipes lately… tried this last night and it did NOT disappoint! Adapted it to my favorite fruit and spices (in oatmeal: pears) and it was delicious. Going to see how it freezes tonight (my guess is it will still be fantastic thawed) and then I’ll be making pans of it in preparation. Thanks for the great recipe!

      1. Just as I thought, still tasted great after the freeze + thaw. Tested 3 different baked oats recipe at once, and this one was definitely my favorite. Thanks for sharing these awesome baked oats with us! 🙂

  2. Hi, the measure mentioned for the baking dish is 8×11, but when I made the recipe, the squares came up very thin, so I suggest you use a smaller one, 5×7 for example, so that you get larger and thicker squares. Very good taste by the way!

    1. Hi! It’s supposed to be fairly thin, but if you would like thicker squares, that’d definitely be a good idea! Glad you enjoyed the taste!!

    1. Yes, you can use fresh or frozen blueberries! If you use frozen fruit, there’s no need to thaw it in advance. Hope you enjoy!

    2. LOVE LOVE LOVE your easy healthy recipes. The ingredients are a pantry staple. Please keep them coming. You have make cooking fun again for me. Thankyou

  3. I made this in a deeper oval casserole dish that was like 9×7 (inches). This is the white Corelle dish, the one with the ridges. Anyway, mine came out like an oatmeal pudding and was good.

    I made it the night before and wasn’t sure if I was supposed to refrigerate or not, so I did to be safe. I microwaved for 30 seconds per serving.

    I’m looking forward to trying the peanut butter variation of this on the website. That one sounds like it might be even better.

  4. It’s just perfect !
    I’ve made it with coconut mild and served with blueberry ice cream I’ve made from soaked cashews , frozen blueberries , 2 actimels , cinnamon , vanilla and 1/2 curd cheese ( it’s called tvaroh and sell it in polish section of tesco ) and it was amazing !!!! The recipe is sooo quick and it came out so nice , not too sweet, just perfect healthy food , many thanks !!!

  5. I made this recipe this morning for my mom & I and it is absolutely delicious! I’ve been looking for healthier breakfast options and this is perfect! I added a dash of brown sugar to sweeten.

  6. Thank you for sharing this recipe. My family absolutely loves it. I left out the coconut oil because I didn’t have any on hand and it was still delicious.

  7. Love these! They are so quick to make and taste delicious! I make them on Sunday’s and take a slice on-the-go with me for breakfast each day of the week. Also store’s well in the fridge.

  8. I have to be honest, I hate oats. I need to eat them for my health. What a conundrum. Until I found this recipe. It’s absolutely delicious! Thank you, this recipe has helped me change my life for the better. Did I mention it’s super tasty 😋

  9. This is so delicious! I have made this at least 5 times within a few weeks:) It is the perfect breakfast or snack with apples and cinnamon!

    1. That’s so awesome! And I agree, you can really vary it up with different fruits and toppings!

  10. This is absolutely delicious! A new favorite in our home. We love it both hot and cold. Also, we enjoy it with chopped apples in place of blueberries. Thank you for posting – Yum!

  11. It was good ! I had to modify as I didn’t have regular oats quick oats, used milk instead of almond since we didn’t have any and i used blue berries and banana. I also left the flax seed whole ! It still turned out very yummy ! I toppped it off with vanilla yogurt ?? my 20 month old daughter liked it too ?

  12. I tried this recipe for breakfast this morning and it was perfect! Really delicious and tastes great with maple syrup on top! Will definitely save this recipe!

  13. Thank you for taking the time to put detailed recipe . My family loved the baked blueberry oatmeal, and so did I.! I actually didn’t have almond milk but managed to make it work with 2%. It was delicious and easy to make. Yummy!!

    1. So glad you liked it and yes the milk substitute is totally fine! Thanks for taking the time to leave feedback!

  14. So easy and so good! I made it to have for breakfast for tomorrow morning (and the next few days) but accidentally put a scoop of soy vanilla ice cream on top! Haha! My daughter is allergic to milk, eggs and treenuts so this was a great recipe for us! I used pumpkin and hemp seeds instead of nuts and it turned out perfect, thank you!

    1. Awww I’m so glad to hear that! And I love that you accidentally put a scoop of vanilla ice cream on it!

  15. Just finished up my first pan of this baked oatmeal. It is great and I love that it doesn’t use eggs. I didn’t have any flaxseed, but I thought it was fine without. Going to try it with peaches and almonds next!

    1. Oh that’s great that you didn’t even need the flaxseed. It usually helps it bind, but you can also use chia seeds in the future. The peaches and almonds sounds awesome…trying that this summer when we have juicy peaches in Michigan! Yum

  16. Just made this recipe for the first time today and it was a hit! Definitely a new favorite in our house and so easy to make!

  17. I bake in a toaster oven that fits a 9X9 square pan. If I halved the recipe do you think that would work in that size. Thanks.

    1. Yes, that should work, but I haven’t tried it myself. I think the time can be reduced. Let me know how it works!

  18. I am anxious to try this recipe! I have everything except flaxseed. Can I leave out or substitute anything for the flaxseed? Thanks so much!

    1. Hi Lily – the flaxseed is used here to act as a binder. So in a sense we’re making a flax “egg” by mixing it with the liquid and then pouring it on top of the oats. You can leave it out, but the mixture might be more crumbly if you leave it out. If you can have eggs, you can try mixing one egg with the liquid ingredients instead. Let me know how it turns out either way!
