What is Banana Bread Baked Oatmeal?

Simply put, banana bread baked oatmeal is an adaptation of our basic baked oatmeal recipe that also includes mashed bananas, melted butter, and chopped nuts.

Instead of cooking down oatmeal on the stove each morning for breakfast, you can make one big batch of this baked oatmeal on the weekend and enjoy it for breakfast each day!

Baked oatmeal is a perfect make-ahead breakfast

Life is too busy and complicated to make breakfast from scratch every day! Part of our meal planning routine is to batch cook items like breakfast and lunch on the weekend. Then, during the week, we simply heat up our pre-portioned meal and enjoy!

Baked oatmeal is perfect because it’s infinitely adaptable, totally gluten free, and comes together quickly in one pot. You can even let it sit overnight or make it right away. It’s so flexible (and delicious)!

Banana Bread Baked Oatmeal Ingredients

Ripe bananas (mashed in your baking dish)
Melted butter
Brown sugar or maple syrup
Chopped walnuts or pecans
Old fashioned or rolled oats
Baking powder

Banana Bread Baked Oatmeal Substitutions

This oatmeal banana bake recipe is incredibly versatile. You can make it without bananas (although then it’s not banana bread…), use your favorite sugar or sweetener (reduce the quantity if you’re using a concentrated sweetener like stevia), swap out or replace the nuts with whatever you have on hand, use vegan or non-dairy milk instead, etc.

You really just need the oats, some sort of liquid, a little fat or oil, salt, and the leavening agent. The rest can be adapted as desired. The final result will be different and for ideal results, follow the steps accordingly.

FAQs about Baked Banana Oatmeal

How should I serve this banana baked oatmeal recipe?

Personally, I like to have yogurt with my oatmeal. Is that weird? We started culturing our own milk kefir because it’s easier to make than yogurt. We like to pour some of that on top for a creamy dose of probiotics.

Here are some other ideas

  • sliced bananas
  • chopped nuts
  • sprinkle some chocolate chips
  • add a dollop of peanut butter
  • drizzle with maple syrup

Should I grease the pan for baked oatmeal?

You definitely can and that will help make it easier to serve your baked oatmeal. However, we typically do not as the oatmeal tends to come out of the baking dish pretty easily. We just soak the pan when we’re done, scrub it out, and it’s ready for the next recipe!

I don’t have bananas. Can I make this anyway?

Yep, go ahead and make it anyway! It won’t be banana bread baked oatmeal, but it will still be great.

Can I use maple syrup instead?

The sweetener is totally flexible in our baked banana oatmeal. If you would rather use maple syrup powder, monk fruit brown sugar, etc, all of those are fine. You can even make it without any sugar if you’re trying to cut back on your sweeteners. In this situation, it won’t be very sweet, but there will be a mild sweetness from the bananas.

Can I use non-dairy or vegan milk?

Yep! This recipe is so flexible. You can also make it with water, but it won’t be as creamy. Try almond milk or coconut milk!

Do I have to use eggs?

Not really. They help bind everything together and add a little protein, but you can make it without. It just won’t rise as well and will likely be denser. Consider adding an additional 1/2 tsp baking powder if you do this.

Can I use a different type of nut?

Go for it! We used pecans in this banana bread oatmeal bake because that’s what we had on hand, but walnuts would be great, too. Have a nut allergy? Skip ’em! No harm done.

Can I add chocolate chips?

Chocolate chips would be so good in these baked oats with banana. Add about 1/2 cup.

Can I prepare this baked oatmeal the night before?

This banana bread baked oatmeal recipe is great prepped the night before! Simply combine everything following the instructions above, but allow it to sit in the fridge overnight. You may need to stir the butter back in to make sure it doesn’t solidify in one place.

Can you make banana oatmeal in the oven?

Yes! It’s so easier. Make one big batch of baked banana oatmeal instead of cooking from scratch every day. This recipe is perfect for meal prepping!

How do you make baked oatmeal?

Simply stir all of the ingredients together in a baking dish. Baked for 30 minutes at 350 degrees in a preheated oven and there you go!

How long do you bake oatmeal bake?

This recipe only requires 30 minutes in the oven. Other baked oatmeal recipes may take longer if they are in a deeper dish or contain frozen fruits. You can bake it longer if you’d like a crispier shell on top. Personally, we wanted our baked oatmeal to resemble oatmeal as much as possible. 30 minutes is perfect for this!

How do you tell if baked oatmeal is done?

We’ve found that this recipe bakes perfectly in 30 minutes. Since individual ovens can vary, you might want to test your recipe using these strategies:

  • Look for a golden top
  • The sides should just start to pull away from the edge of the container
  • A knife test should come out mostly clean
  • The baked oatmeal should look visibly firm
  • If you gently press the middle of the oatmeal, it should have a slight bounce
