How to make zucchini oatmeal
This is perfect for back to school breakfast because you can grab it and go!
- Grate zucchini and set aside. Mash banana in a mixing bowl.
- Whisk in milk, peanut butter, egg, and vanilla.
- Add oats, baking powder, cinnamon and salt. Toss in a handful of chocolate chips.
- Pour mixture into a greased baking dish and bake for 40 minutes.
- Cool, slice, devour!
Key ingredients and substitutions
This recipe is naturally sweetened with ripe bananas for a no added sugar treat, but I love it with chocolate chips, duh. You can lean into the spices and even add a pinch of nutmeg if you're feeling fall right this very moment.
- Old fashioned oats: There's nothing better than whole grain rolled oats to kick off your morning with a shebang. To make this gluten free, simply use certified gluten free oats.
- Zucchini: Or yellow summer squash. Who could deny a serving of veggies with breakfast? No need to peel or squeeze out the water with 15 paper towels, yay! We're depending on that liquid.
- Banana: For natural sweetness and moisture. The riper, the better. You can substitute applesauce but it will be less sweet.
- Peanut butter: Natural peanut butter adds fabulous flavor to this bake. I prefer the drippy kind that's salted. Any nut butter would work here, or tahini for a nut-free version.
- Milk: Milk adds some moisture and fluff. I used unsweetened vanilla almond milk since I always have it on hand, but any milk you fancy is great here, like dairy or oat milk.
- Egg: To help bind the oatmeal. You can also use a flax egg to make this recipe vegan.
- Vanilla extract + cinnamon: Flavor on flavor.
- Salt: Never underestimate the power of salt to bring out flavors. Fine sea salt or kosher salt are fine. Be sure to double it if your nut butter is unsalted.
- Chocolate Chips: I just can't not add chocolate! It balances out the flavors so well. I also like walnuts for toasty flavor, crunch and some heart healthy fats. Yes, ma'am.
Which oats are best?
Old fashioned (rolled) all the way! Steel cut take way longer to cook and instant would be too quick. Right in the middle is what we want.
How to serve
- add a dollop of peanut or almond butter for extra healthy fats
- serve alongside scrambled eggs for a protein boost
- enjoy as is on-the-go with a hot cup of coffee!
Storage tips
Store leftovers in an air-tight container in the refrigerator for up to 5 days.
I like to slice it into six or nine pieces for a hearty breakfast portion; but if you want more of a snack, you can slice it into 12 pieces.
Can you freeze baked oatmeal?
Yes! This is a stellar make-ahead, freezer-friendly breakfast. So great for new moms! Once cool, place the pan in the freezer, covered, for up to 3 months. You can defrost overnight and then reheat in the microwave.
You can also freeze individual servings in freezer-baggies for easy portioning.

I made these last month just after I lost my sense of taste because of Covid (but before I realized it) and thought they didn’t really taste like much. Ha! Made them a second time after my tastebuds recovered, and they were DELICIOUS! My vegan friends and I gobbled them up as dessert on a picnic—I made the vegan version with a flax egg. Super yummy, healthy, easy to make. And—great way to use that summer zucchini from the garden! Great recipe.

I'll be using summer squash, as I don't care for zucchini, and the garden has overproduced again.
