Banana-Walnut Baked Oatmeal

“I received free samples of California walnuts mentioned in this post. By posting this recipe I am entering a recipe contest sponsored by the California Walnut Commission and am eligible to win prizes associated with the contest. I was not compensated for my time.”


This Banana-Walnut baked oatmeal can be prepped and cooked ahead of time for a quick, healthy and nutritious breakfast to keep you feeling full all morning long. A combination of  wholesome and hearty oats and walnuts form the base of this recipe, with sweet ripe bananas layered over top. A mixture of wet ingredients are poured over the oats then baked to create a perfect bread-like pudding breakfast casserole. It’s like biting into a warm slice of banana bread and that, my friends, is indeed a very good thing.


Let’s take a minute and talk about the important components walnuts provide for a nutritious and healthy diet. One ounce of walnuts has 2.5 grams of the essential plant-based omega-3 alpha-linolenic acid (ALA), 4 grams of protein and 2 grams of fiber to keep you feeling full. Walnuts contain rare and powerful antioxidants, support brain health, and benefit in treatment of type 2 diabetes along with other health benefits. They’re a delicious way to add extra nutrition, flavor and crunch to a meal and can easily be incorporated into a healthy diet by chopping  and adding to salads, vegetable dishes, fruit, or even dessert.


This banana-walnut baked oatmeal is highly adaptable and the bananas can be substituted for other seasonal berries and fruit. Baked oatmeal is simple to throw together for a quick and easy breakfast option that’s both healthy and filling. It reheats well, so you can eat on the leftovers all week long. I like to add additional maple syrup or peanut butter over top before eating it.

    This baked oatmeal looks amazing – those bananas on top, omg! Do you think I could make this without the egg, to make it vegan? I really want to try it <3

    Mmm mmm mmm! It’s always good to switch up the typical bowl of oatmeal by baking! And banana walnut is one of the best flavor combinations to turn to 🙂

    I haven’t tried it without the egg so I’m not %100 sure. Maybe you could try using a chia or flax egg?
