This dessert-like banana bread baked oatmeal is rich, sweet, hearty, and totally breakfast worthy, thanks to hearty oats and the natural sweetness of bananas. So if you’re tired of using your brown bananas for actual banana bread, you can change things up a bit with this banana bread flavored baked oatmeal, which makes a great make-ahead breakfast meal prep for the week. BONUS: it’s freezer-friendly!
What is Baked Oatmeal?
If you’re new to the world of baked oatmeal, it’s a wonderfully rich and moist breakfast treat. It’s basically oats baked into a custard. Kind of like bread pudding, but with oats instead of bread. If you think you don’t like oats because they tend to be gooey when boiled with water, try baked oatmeal. It’s soft, moist, and rich, but not at all gooey. Some people also mistakenly think baked oats are crunchy, but they’re not.

How to Store the Leftovers
This recipe makes a pretty big batch, so you’ll want to save the leftovers to eat throughout the week. Make sure to refrigerate your baked oatmeal soon after cooking. I like to divide my baked oatmeal into single servings right after baking, then refrigerate them in individual containers. Once chilled, you can keep the baked oatmeal in the refrigerator for about 5 days, or freeze for about 3 months.
How to Serve Banana Bread Baked Oatmeal
Baked oatmeal can be eaten hot OR cold. You can eat it as-is, or pour cold milk over top. And, if you like things a little sweeter, you can drizzle a little maple syrup over top.
Can I Use Steel Cut Oats?
You can not substitute steel cut oats in this recipe without making other changes because steel cut oats require a lot more moisture and a longer cooking time than rolled oats. While it may be possible to tweak it to make it work, I have not tested this method so I can not offer suggestions for that particular substitution.

How to Make Banana Bread Baked Oatmeal – Step By Step Photos
Preheat the oven to 375ºF. You’ll need 1.5 cups mashed bananas, which is about three bananas. I like to mash my bananas right in a liquid measuring cup so I can see the volume on the side.
Add the mashed bananas to a large bowl along with ⅓ cup brown sugar, 2 large eggs, ½ tsp salt, ½ tsp vanilla extract, 1 tsp baking powder, ¼ tsp cinnamon, and ⅛ tsp nutmeg. Whisk the ingredients together until they’re evenly combined.
Add 2 cups milk and whisk to combine again. It’s easier to whisk in the milk after the other ingredients have been combined because it causes less splashing.
Finally, stir in 2.5 cups rolled oats and ½ cup chopped walnuts.
Pour the oat mixture into a 9×9-inch casserole dish.
Bake the oatmeal in the preheated 375ºF for 45 minutes, or until it’s golden brown on top and around the edges.
Serve the banana bread baked oatmeal immediately, or divide into six portions and refrigerate for later!
Serve hot or cold, alone or topped with milk.
I didn’t have any walnuts so I just used some crushed pecans. I used a little pumpkin spice seasoning vs nutmeg and a dollop of Greek vanilla yogurt on top. This is a yummy find. Thank you so much!
I’ve made this recipe so many times now I’ve basically got it memorized. My husband always asks for it, and I’m happy to make it because I know it’s healthy for us.
Also wanted to add that I’ve successfully mixed together the wet ingredients the night before. Then in the morning I mix in the oats and put it in the oven for a fresh hot breakfast.
I’ve been making this almost every week for 2 years. I add flax and hemp hearts and don’t always have walnuts. I also add chopped dates on top. It freezes well and my toddler also loves it too.
I used egg replacement and maple syrup drizzle. The dish was well liked by the family. The house smells so good. Thanks for the recipe.
So good! The perfect healthier alternative to banana bread! I made this to meal prep for the week and I’m looking forward to having it each morning
Made this on Christmas day today and the fam definitely enjoyed it. Some people poured a little milk over their serving, others just had as is with blueberries. I basically made the recipe as described except I used less brown sugar since our bananas were super ripe and would definitely make it again or try some additions like chocolate chips. Definitely a keeper and super quick and easy. Thanks!
Delicious!! Followed recipe for the most part. Used what I had in the kitchen cupboard. Quick Oats and almonds that I chopped up. Will make again for sure!
