This blueberry baked oatmeal has become my go-to weekend breakfast that lasts all week long. I'm not kidding when I say Emily requests this every single Sunday morning! What started as a way to use up those gorgeous summer blueberries has turned into our family's most-requested breakfast recipe.
Last month, I was scrambling to find something healthy that would keep Emily full during her busy school mornings. She's not a huge breakfast fan (typical teenager, right?), but this baked oatmeal changed everything. It's naturally sweetened with bananas and pure maple syrup, packed with fiber, and honestly tastes more like dessert than breakfast.
The best part? You can make this entire batch on Sunday and have breakfast ready for the whole week. No more morning chaos trying to figure out what to eat! I love when recipes make life easier, don't you? Try my buttermilk pancake mix recipe for another make-ahead breakfast option that'll save you time during busy mornings.

Ingredients For The Best Blueberry Baked Oatmeal
For the oat base:
- 2 cups rolled old-fashioned oats
- ¼ cup pure maple syrup
- 1 teaspoon baking powder
- 1½ teaspoons ground cinnamon
- ½ teaspoon sea salt
For the wet ingredients:
- 2 cups unsweetened vanilla almond milk
- 1 tablespoon ground flaxseed (or 1 large egg)
- 2 tablespoons coconut oil, melted
- 2 teaspoons pure vanilla extract
- 2 ripe bananas, mashed
For the mix-ins:
- 1¼ cups fresh or frozen blueberries, divided
- Additional blueberries, nut butter, and extra maple syrup for serving
I always keep these ingredients stocked in my pantry because we make this healthy baked oatmeal recipe so often. The key is using really ripe bananas - they should have brown spots for maximum sweetness!
How To Make Perfect Blueberry Baked Oatmeal
Getting Started
- Preheat your oven to 350°F and grease an 8x8 inch baking dish with a little coconut oil or cooking spray.
- Mash those ripe bananas in a large mixing bowl until they're mostly smooth. Don't worry about getting every lump out - a few chunks actually add nice texture!
- Whisk together all the wet ingredients including the mashed bananas, almond milk, melted coconut oil, vanilla extract, and ground flaxseed (or egg if using).
Mixing The Dry Ingredients
- Combine all dry ingredients in a separate bowl - oats, baking powder, cinnamon, and salt. Give everything a good stir.
- Pour the wet mixture over the dry ingredients and gently fold everything together until just combined. Don't overmix!
- Fold in 1 cup of the blueberries, saving the remaining ¼ cup for topping. This way you get blueberries throughout and a pretty presentation on top.
Baking Your Oatmeal
- Transfer the mixture to your prepared baking dish and spread it out evenly. Sprinkle those reserved blueberries on top.
- Bake for 35-40 minutes until the top is golden brown and set. The center should be firm but still slightly soft.
- Let it cool for about 10 minutes before serving. Trust me on this - it needs time to set up properly!
I learned the hard way that cutting into this too early results in a mushy mess. Emily still teases me about the time I served her "blueberry soup" because I was too impatient to wait!
Storage And Reheating Your Baked Oatmeal
This easy blueberry oatmeal bake keeps beautifully in the refrigerator for up to 5 days. I cut it into 6 portions and store them in individual containers for grab-and-go breakfasts.
To reheat, just pop a portion in the microwave for 30-60 seconds. You can also reheat the whole dish covered in a 300°F oven for about 15 minutes.
The texture actually gets better after a day in the fridge! The oats absorb more moisture and the flavors meld together perfectly.
Tips And Variations For Blueberry Baked Oatmeal Success
- Use really ripe bananas - They should have brown spots for natural sweetness and the best flavor
- Don't skip the flaxseed - It acts as a binding agent and adds healthy omega-3s (but egg works great too!)
- Mix gently - Overmixing can make your oatmeal dense and gummy
- Try different fruits - Raspberries, blackberries, or diced apples work wonderfully
- Make it chocolate - Add 2 tablespoons of cocoa powder to the dry ingredients for a chocolate version Emily absolutely loves
- Boost the protein - Stir in a scoop of vanilla protein powder with the dry ingredients
Want to switch things up? I sometimes add chopped walnuts or a handful of mini chocolate chips (don't tell Emily I sneak extra nutrition into her treats!).
