Banana Zucchini Baked Oatmeal


Easy recipes is the name of my game right now! Since I’m nursing Wyatt I find myself hungrier than ever before, especially in the mornings. Having something like this Banana Zucchini Baked Oatmeal on hand is a life saver! If I have time, I will put a slice on a plate, warm it up and eat it with a fork and a little bit of maple syrup. But often I don’t have time or both hands available, so I will eat it as is, cold out of the refrigerator. To me, it tastes just as good 3 days later than it did when it was fresh out of the oven, which makes it the perfect make-ahead breakfast dish.


Banana Zucchini Baked Oatmeal Ingredients

What Ingredients Will I Need? 


Oats – Obviously, oatmeal calls for oats! Use rolled, old-fashioned oats, not the quick-cooking kind! 

Milk – I like to use oat or almond milk, but any kind of milk you like will work just fine. 

Egg – 1 large egg helps hold everything together.

Banana – 1 mashed banana helps keep it moist and adds some sweetness. 

Zucchini – Shredded zucchini for moisture and a healthy kick. 

Maple Syrup – the main sweetening ingredient, aside from the banana. 

Cinnamon, Vanilla Extract and Salt – for flavor. 

Baking Powder – helps it to rise just a little bit and keeps it from getting too dense. 

Flax Meal and Chia Seeds – Optional ingredients that add texture and nutrients.

How To Make Banana Zucchini Baked Oatmeal


It’s as simple as throwing all the ingredients together in a large bowl and mixing them up. The most time consuming part of the whole recipe is shredding the zucchini, which doesn’t take more than a few minutes! Once everything is mixed up, spray a baking dish and spread the bater in an even layer. Then bake the oatmeal for 30-35 minutes. Once it’s set, let it cool before slicing or serving.

How to Store Banana Zucchini Baked Oatmeal


There are a fews ways to store this baked oatmeal once it has cooled. 

If you are planning to eat it all within 5-7 days:

For the easiest option, you can slice it and leave it in the pan, cover the pan tightly with plastic wrap to keep it fresh and store in the refrigerator. 

OR, if you don’t want the pan taking up too much room, you can put the slices in an air tight container. Once they are completely cool, you can stack them on top of each other and they will not stick together. 

If you won’t finish it all within 5-7 days: 

I suggest you freeze the slices individually. Wrap each slice in plastic wrap and store the slices in an air tight container or ziplock bag. When you want to reheat, remove the plastic wrap and heat in the microwave for 1 minute. OR let it defrost on the counter top and eat at room temperature or warm in the microwave for 30 seconds.
