This Blueberry Banana Baked Oatmeal is easy to make and perfect for a quick, healthy breakfast or snack throughout the week!

Baked oatmeal studded with blueberries in a white baking dish.

Josh and I went on our trip to Colorado last week and while it involved A LOT of driving, it was really a lot of fun. But now it’s back to reality and we’ve been slowly getting back into our routine and trying to unpack everything.

I’ve been really trying to focus this week on easier meals that don’t require a lot of time. This past weekend I made another batch of this Blueberry Banana Baked Oatmeal so that we had something to warm up and eat for a quick and easy breakfast.  Now that it’s also back to school time, I thought this would be the perfect time to share it all with you too. Because I can’t possibly be the only one rushing out the door every morning? That’s not just me, right?

One of my favorite things about this healthy baked oatmeal recipe is that it’s sweetened naturally with bananas and honey. There’s nothing better than an easy breakfast in the morning that you can also feel good about eating.

Ingredients For This Recipe

This banana blueberry baked oatmeal comes together with a handful of pantry staples. Here’s what we’ll be using to make this baked oats recipe: 

  • Old Fashioned Rolled Oats: If you’re looking for a gluten-free option, you can replace the oats in this recipe with gluten-free rolled oats.
  • Baking powder: Helps the baked oatmeal rise. 
  • Ground cinnamon: Adds flavor and complements the fresh fruit perfectly. 
  • Salt: Balances out the sweetness from the bananas and blueberries. 
  • Mashed bananas: Ripe, speckled bananas are best in this recipe. If your bananas aren’t ripe enough yet, place them in a brown paper bag for 1-2 days to ripen quicker.
  • Milk: Any type of milk will work in this recipe. I used almond milk, but use what you have on hand. 
  • Honey: Sweetens the blueberry banana oatmeal. 
  • Egg: Binds everything together and prevents the oats from crumbling once baked. 
  • Vanilla extract: Pure vanilla extract is best in this recipe. 
  • Blueberries: Fresh or frozen blueberries will work. 

How to Make Baked Oatmeal 

Simply whisk together the wet ingredients in one bowl and the dry in another. Add the wet mixture to the dry and stir to combine. Gently fold in the blueberries. 

Turn the mixture into an 8-inch square baking dish and bake for 30-40 minutes, or until the top is set and lightly golden brown. Mine is usually perfect around 35-36 minutes.

Let the blueberry banana baked oatmeal cool for 10 minutes before slicing. Baked oatmeal has kind of a soft and chewy texture, but it’s absolutely delicious and even perfect for picky eaters. I love to make a batch of this Blueberry Banana Baked Oatmeal and eat it over some Greek yogurt. It’s also great with a little pure maple syrup, almond milk, or fresh fruit on top.

FAQ’s

Can I Use Frozen Blueberries? 

I’ve tested this recipe with frozen blueberries and they work great too, which means that you can make this recipe all year round. If you are using frozen blueberries, just make sure to gently mix them in so they don’t turn your oatmeal purple.  You can also change up the berries in this recipe and use your favorite or whatever you have on hand.
