Zucchini Bread Baked Oatmeal

GF V VG

This zucchini bread baked oatmeal recipe makes it easy to sneak veggies into your morning. It’s perfect for meal prep — just reheat and serve!

Given how popular my zucchini bread oatmeal and zucchini bread overnight oats recipes are, I knew I needed to create a zucchini bread baked oatmeal recipe for you!

I’m willing to go out on a limb and say that we could all use more veggies in our lives. Maybe you’re pretty good at incorporating vegetables into lunch and dinner but rarely have vegetables for breakfast?!

That changes with this recipe. We’re “sneaking” shredded zucchini into baked oatmeal and turning it into a zucchini bread baked oatmeal.

The best part? There’s no need to squeeze and drain the zucchini for this recipe because the extra liquid helps make the oatmeal super moist. It also adds a nice mild flavor and texture.

If you have a garden or know someone that has a garden, it’s that time of year where everyone seems to have an abundance of zucchini! So send them this recipe and get ready for the tastiest breakfast of the summer. 😉

Here’s What You Need

  • old fashioned rolled oats – my fave brand of oats is Bob’s Red Mill. They have a gluten-free oats if needed too!
  • walnuts – I love the added crunch walnuts provide plus they have great health benefits.
  • pure maple syrup – pure maple syrup is the perfect natural sweetener to use for baked oatmeal in my opinion!
  • baking powder – a rising agent and helps lighten the texture of the baked oatmeal. It prevents it from becoming too dense or heavy.
  • ground cinnamon – for a little spice.
  • sea salt – to bring all of the flavors together.
  • milk – I like to use almond milk but any kind works in this recipe
  • egg – if you’re vegan you can swap in 1 Tablespoon ground flaxseed
  • coconut oil – I like using extra virgin coconut oil. I’ve purchased several different brands of coconut oil before, but Nutiva organic extra virgin coconut oil is my favorite.
  • pure vanilla extract – a wonderful flavor enhancer.
  • zucchini – we’re grating the zucchini, but there’s no need to squeeze out the liquid

Can I Make This Ahead of Time?

Yes, you can absolutely make this ahead of time. I like to prepare the baked oatmeal as the recipe suggests, let cool, cover and place the dish in the fridge to store. You can do this 1-2 days in advance and just reheat portions for breakfast throughout the week.

How to Store and Reheat

I recommend storing baked oatmeal in an airtight container in the refrigerator for 4-5 days or in the freezer for up to 3 months. For freezing, I recommend cutting the oatmeal into portions, wrap in plastic wrap and place the portions in a large freezer bag. The individual servings make it easier for reheating one portion at a time.

To reheat the entire pan of baked oatmeal: cover with foil and reheat in the oven at 350ºF for about 20 minutes or until warm.

For individual portions: set oven or toaster oven to 350ºF and bake for 5-10 minutes. You can also reheat in the microwave for 1 minute. Once warm, add your toppings and enjoy!

      I used thick cut rolled oats and rye flakes, 1 Tbs ground flax instead of egg, and added a couple Tbs raisins. Really enjoyed the texture and flavor of this bake. I did not let it cool much before serving and the squares fell apart. May also be due to the thicker flakes. Hadn’t realized how many variations you’ve done and plan to make a weekly bake as part of my 3 day a week hot grain breakfast routine. Thank you!

      This recipe has become a go-to for me! Delicious as-is, though I tend to add ginger/allspice as I love those flavors paired with cinnamon. Reheats great and is even tasty cold when I’m rushing out the door and want to start my day with something well-rounded and satisfying. Try it!

      I was expecting more of a “bar” but I made a couple changes to the recipe, I’m not really sure what the texture was supposed to be but basically I just made oatmeal really slowly lol. First I soaked the oats overnight to improve digestability. Then this morning when I started to make this it was clear that 2c of milk would be far too much since the oats weren’t going to absorb the liquid, so I did 1c. and finally I baked it in a loaf pan because that was all I had. So then I kept hoping it would bake into a “bar” or maybe something bread-ish, but after more than an hour in the oven I decided to just pull it out. So I didn’t get at all what I hoped for, but the flavors are good and obviously with how much I changed its not a fault of the recipe that it wasn’t what I expected

        Hey Cass – My baked oatmeal recipes aren’t supposed to be “bar like.” They’re essentially like a bowl of oatmeal but baked. 🙂 If you’re looking for more of a bar recipe you could try my berry baked oatmeal bars.
