Breakfast never tasted this good! Banana Nut Baked Oatmeal is the ultimate mashup of classic banana nut bread and hearty oatmeal. It’s easy to make, and both make-ahead and freezer-friendly—perfect for busy mornings.

Baked oatmeal has become a staple in my house. We’re big fans of banana bread and oatmeal, so this recipe was an instant hit! My whole family, including my husband, LOVES baked oatmeal. Whether it’s my Pumpkin Baked Oatmeal or Oatmeal Cups, this cozy dish is always a favorite.
I always have overripe bananas lingering around, waiting to be used. While I often turn them into banana crumb muffins or banana bread, I’ve been reaching for this baked oatmeal more and more. It’s just as easy, naturally sweet, and so satisfying!
I’ve tested this recipe with sugar, maple syrup, and honey—all three work great! If your bananas are extra ripe, you can cut back on the sweetener. If they’re just ripe, the suggested amount of sugar will be perfect.
