Zucchini Bread Baked Oatmeal

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. 😉

Ingredients in Zucchini Bread Baked Oatmeal

  • old fashioned rolled oats
  • walnuts
  • pure maple syrup
  • baking powder
  • ground cinnamon
  • sea salt
  • 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
  • pure vanilla extract
  • zucchini – we’re grating the zucchini, but there’s no need to squeeze out the liquid

How to Make Zucchini Bread Baked Oatmeal

Turn your oven on and preheat to 375ºF so it’s ready to bake the oatmeal by the time you’re done mixing! Prep your baking dish by spraying it with cooking spray.

In a large bowl, combine the oats, half of the walnuts, baking powder, cinnamon and salt. Add in the milk, maple syrup, egg, coconut oil, vanilla and grated zucchini. Stir to combine. Carefully pour the oatmeal mixture into the prepared baking dish and scatter the rest of the walnuts over the top. Bake for 40 minutes or until the top is nice and golden brown. Let it cool a little bit before serving. I like to top mine with peanut butter or almond butter and a splash of almond milk.

Make Baked Oatmeal Ahead of Time

You can totally make baked oatmeal ahead of time! Here’s what I recommend:

Option 1: Bake and Then Reheat Before Serving

  1. Prepare baked oatmeal as the recipe suggests. Once baked, let the oatmeal cool, cover the baking dish and place in the fridge. You can do this 1-2 days in advance.
  2. When ready to serve, take oatmeal dish from fridge, cover with foil and reheat in a 350°F oven for about 20 minutes. For individual portions, set toaster oven to 350°F and bake for 5-10 minutes or reheat in the microwave for 1 minute.

Option 2: Prep as Much as You Can Without Baking

  1. Mix together your dry ingredients in a bowl, cover and let sit out on the counter until morning.
  2. Mix together all the wet ingredients in another bowl, cover and store in the fridge until morning.
  3. In the morning, simply mix the wet and dry ingredients together, pour oatmeal mixture into your prepared baking dish and bake as recipe suggests.

      Followed the recipe except added slightly less than 1/4 c maple syrup based on comments that it was sweet – it came out perfectly! I’m always looking for ways to sneak veggies to my picky 16 month old and she gobbled this up! My husband is one of those weirdos that doesn’t like oatmeal and even he loved it! We will have this in our regular meal rotation at our house

      This was the first time I made baked oatmeal, and it was very easy and super tasty and filling. Exceeded all my expectations! Tastes like cake, which is definitely not a bad thing! Next time I might try sweetening it a little less… When I’ve used up our zucchini harvest, I’ll definitely try out your other baked oatmeal recipes. Thanks for sharing!

      Grated ginger
      Lemon zest and juice
      Pumpkin seeds
      Apples
      Carrots

      And of course raisins.

      😋😋😋💝

      tasted good and smelt amazing but was really wet and stodgy like the raw mix or like porridge even though it was cooked for the full time and more!!! Was looking forward to it but really disappointed I’m afraid 😞

        Hey Lorna – So sorry to hear that this recipe didn’t turn out for you. Did you change anything about the recipe? It might have just needed a bit more time to cook. Every oven is different so the cook time can vary from oven to oven.

      Hi! I wanted to make this for a brunch I am hosting tomorrow – can I prep all tonight and leave in the bake dish in fridge until tomorrow am to throw in oven? I want it to be nice and warm when I serve!

      1. Brittany Mullins
        August 17, 2020 AT 2:06 pm

        Hi!! I usually don’t recommend this with baked oatmeal because the oats will soak up the liquid overnight and it might turn out dry. The coconut oil will also solidify in the fridge. So there’s two options to save time: 1) You could combine all the dry ingredients in a bowl, cover and leave out on the counter overnight, then just add in your wet ingredients in the morning. 2). You could mix everything besides the milk together in a big bowl and place it in the fridge overnight. The next morning, stir in the milk until combined, pour batter into your prepared baking dish and bake! The coconut oil will be solid after sitting in the fridge overnight, but since you mixed it in melted the day before it should still be well dispersed. It also might take a little extra cook time since it’s going in the oven cold.

        Sorry, I know this isn’t the answer you were hoping for. Let me know what you decide to do!

      Prepped most of this last night and finished off shredding the zucchini this am – combined ingredients and topped with pecans and shredded coconut and baked. My house smelled like I had a coffee cake in the oven and this dish tasted just amazing once eaten, thank you so much, this is a keeper!! (It was a messy scooping out the first piece, I hope it solidifies a bit more as it cools but no worries, I ate my entire portion messy and all :)!! )

          You are most welcome Brittany, I have been loving your site and recipes for years and this one doesn’t disappoint!! Hope I wasn’t confusing with prepping before hand, I had all dry ingredients combined and left in bowl on counter overnight and used Avocado oil instead of coconut and had all but the shredded zucchini combined and in the frig. Made getting this into the oven and eaten so much easier lol!! Thanks again!!

      This was one of the first recipes I ever tried from this website, and I loved it! Just make sure you don’t use more than the serving size given for zucchini and that you keep the leftovers in the fridge. I thought it tasted great with either a peanut butter or honey drizzle on top!

        Totally!! I’d just use my baked oatmeal cups recipe as a base and add in shredded zucchini. 🙂 Let me know how they turn out if you end up trying them.

      Obsessed. In love. This is amazing! Like others who commented, I didn’t have walnuts so I subbed chocolate chips (amazing idea), though I suspect the recipe would work fine without either. This was SO good. My husband and four year old both approved as well!

      Tastes great! A bit too sweet for my taste though, I think I’ll opt for less sugar next time. Make sure you get the consistency right too because mine ended up a bit too runny and not very golden which was my fault.

      Can I use steak cut oats. I assume
      I would need to maybe soak or slightly cook them. Thanks for your wonderful recipes.

      1. Brittany Mullins
        April 26, 2020 AT 12:23 pm

        Yes! You can definitely use steel cut oats… you’ll just need to cook it longer. No soaking needed, unless you want to!

      Made this for our “baked oatmeal” breakfast day today and it was 100%! We drizzled a little melted chocolate we had leftover, which didn’t hurt 😉! Also great with drizzled PB. We love all of your baked oatmeal combos, thanks for the great ideas!

      Can this be kept/served at room temperature? Or does it need to be refrigerated and heated prior to serving. Thank you, can’t wait to try!
