I’m not sure how many of you remember my delicious peanut butter and jelly baked oatmeal, but it was by far one of my favorite make ahead breakfasts of all time.

Today, I’m back with another delicious baked oatmeal that’s packed with vegetables (HI ZUCCHINI), protein-packed peanut butter, and naturally sweetened with just a touch of pure maple syrup.

Okayyyy and mini chocolate chips, because you know how we do. #chocolateineverybite

Ingredients in zucchini baked oatmeal

This zucchini bread baked oatmeal is great to make for breakfast because it’s ridiculously easy. Just mix everything together in one bowl, pour it into a pan and bake until done! The texture is reminiscent of peanut butter oatmeal cookies. Delicious for breakfast, but also perfect warmed up in the afternoon with a tall glass of milk.

Here are the main ingredients you’ll need:

  • peanut butter (or almond butter!)
  • pure maple syrup or honey
  • egg
  • vanilla extract
  • milk (I like almond milk)
  • old fashioned rolled oats, gluten free if desired
  • shredded zucchini
  • mini chocolate chips

How to store, freeze & reheat this zucchini bread baked oatmeal:

To store this zucchini bread baked oatmeal in the refrigerator:

Be sure the baked oatmeal has completely cooled, and then cover your 8×8 inch pan with tinfoil before transferring it to the refrigerator. It will stay good covered in the refrigerator for 3-4 days, and you can reheat individual slices in the microwave for 30-60 seconds. I like to individually store slices in airtight containers for quick, on-the-go breakfasts.

To freeze & reheat this zucchini bread baked oatmeal:

Once the baked oatmeal has completely cooled, cut it into 6 squares and wrap each square in plastic wrap and tinfoil. When you’re ready to eat it, place the unwrapped frozen square of baked oatmeal on a microwave safe dish and microwave it at 30 second intervals for 1-2 minutes. If you’d like to freeze the entire baked oatmeal for later, simply reheat it in the oven for 20-25 minutes at 350 degrees F while it’s covered with tinfoil.

  • 1/2 teaspoon baking powder
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon nutmeg

Recipe Notes

Feel free to use almond butter or cashew butter instead of peanut butter.

If you leave out the chocolate chips, I suggest adding fresh fruit, such as 2/3 cup blueberries or chopped up bananas.
