Blueberry Banana Baked Oatmeal

This blueberry banana baked oatmeal is one of my favorite go-to breakfast recipes. It’s easy, it’s quick, it’s delicious!

You can use blueberries and bananas as I did in this recipe or change out the fruit, depending on the season. 

This recipe is quite versatile!

Can I use other fruit instead for this baked oatmeal?

Absolutely! I used blueberries and bananas because that is what I had on hand, but I can see this being made with a variety of fruits!

The possibilities are endless. Maybe try it with apples? I’d be super into that as apples are my favorite fruit. Strawberries will also work. You could even add strawberries into this combo instead.

What Ingredients Go Into this Blueberry Banana Baked Oatmeal

For this particular recipe, I used blueberries and bananas as my fruits but you can use strawberries, blackberries, apples, or even peaches.

I know after this is all gone I will be making more. This is a great way to get some more fruits into your diet. You could also add some flaxseed meal for a fiber boost or some chia seeds to up those omega 3’s.

How to make baked oatmeal?

Baked oatmeal is so quick and easy to make. You gather your ingredients (more on that below!) and put it together in a bowl making sure that the oatmeal is coated evenly.

Then you throw it in a baking dish and bake it in the oven.

How To Store Blueberry Banana Baked Oatmeal

It’s delicious right away but can absolutely be heated up later.

I store it in the glass dish that I made the oatmeal bake in. The one I have came with a lid so it’s perfect for this purpose.

I often eat this the next day and for breakfast for almost a full week.

I love oatmeal, but I rarely have time in the morning to make anything. Having a tray of this ready to go is a lifesaver. All I have to do is scoop it into a bowl and warm it up at the office.

When do you put the sugar in? I forgot to put it in, and then realized it wasn't on the instructions. We put some syrup or honey on top. Still good! :)

Hey Kandace! Thanks for your note. I fixed the recipe. You would usually add it in with the other dry ingredients but on top is fine. :D I'm glad that it still turned out good for you! I really should make up a double batch of this so I will have it for the week. Have a great night! :D

Yes. You may need to bake it longer with steel cut oats though. Here is a similar recipe with steel cut oats for your reference:

Let me know how it turns out!?

Hi! Would honey work instead of maple syrup?

Hi Riley!

I don't see why not! I would totally substitute honey in place of the maple syrup. I would suspect that the maple syrup will be easier to incorporate though.

I hope it works out for you!
