Key Ingredients

Here are the important ingredients in this blueberry banana baked oatmeal recipe. Scroll to the recipe card for the printable recipe with exact measurements.

• Rolled oats – Don’t substitute quick oats, or you’ll end up with mushy baked oats.
• Spices – Cinnamon and nutmeg add a hint of warm spice. You could also use a blend, like pumpkin or apple pie spice.
• Baking powder – Helps create a light, fluffy texture.
• Mashed Bananas – Similar to baking banana bread, ripe or even overripe bananas are best for banana baked oatmeal recipes. The riper they are, the more sweetness they add.
• Unsweetened almond milk – You can substitute any milk of your choosing.
• Egg white – Adds protein and helps bind the oatmeal when baked.
• Maple syrup – Just a touch of sweetness! Honey or agave is a good substitute.
• Vanilla extract – You could also use an equal amount of vanilla paste.
• Fresh blueberries – Frozen blueberries will work in a pinch too. You can also switch it up with blackberries, raspberries, etc.
• Gluten-free flour – To make the entire dish gluten-free, be sure to use gluten-free certified flour and oats.

How to Make Baked Banana Blueberry Oatmeal

Ready to make this baked oatmeal? The batter comes together in minutes, and your oven takes care of the rest. You can also make an entire pan of this blueberry banana baked oatmeal the night before, and just pop it in the oven to reheat in the morning.

1. Combine the wet ingredients. Mix the mashed banana, almond milk, egg white, maple syrup, and vanilla extract in a bowl.
2. Add the dry ingredients. Next, stir in the rolled oats, cinnamon, nutmeg, baking powder, and a pinch of salt. Mix again so the oatmeal is well-combined.
3. Add the blueberries. In a separate bowl, toss the blueberries with flour. This helps to keep the berries from sinking to the bottom of the oatmeal while it bakes. Then, gently fold the coated blueberries into the batter.
4. Fill the pan and bake. Now, pour the oatmeal into a greased 9×9 baking dish. Bake this banana blueberry oatmeal at 375ºF for 35-40 minutes, or until the top is golden brown and the batter no longer jiggles when you shake the pan. Let it cool, then serve!

Quick Tips for the Best Baked Oatmeal

• It’s OK if the oatmeal looks a bit runny. Do not be concerned if it seems like there’s too much liquid when you pour it into the pan. The oats will absorb the liquid while they bake.
• Enjoy warm. However, for clean slices, do let the baked blueberry and banana oatmeal cool for 10 minutes before you cut it.
• Use the right oats. Be sure your oats are not instant oats or steel-cut oats. The former makes the texture mushy, while the latter is too chewy.
• Try different fruit. Feel free to swap out the blueberries for chopped strawberries, raspberries, blackberries, or pitted cherries.

Serving Suggestions

My favorite way to enjoy this blueberry baked oatmeal is warm, topped with fresh blueberries, bananas, and a drizzle of almond butter. You can also add some whipped cream or plain yogurt on top and add a drizzle of maple syrup or honey for some added sweetness. If you want to enjoy this like traditional oatmeal, have it in a bowl with some extra milk and a spoon!

How to Store Leftovers

• Meal prep it to keep in the fridge. This baked banana blueberry oatmeal is ideal for meal prep! Leftovers will last in the fridge for up to 5 days.
• Freeze. You can freeze leftovers for up to 3 months. Cut into individual serving sizes and freeze in a Ziploc bag or other airtight container. This is perfect for meal prep, as you can just pull individual servings down when you need them. I recommend adding a splash of water before reheating in the microwave so they don’t dry out.
• Reheat. Reheat the baked oatmeal in the oven at 350ºF or you can reheat individual servings in the microwave.
