Ingredients for Zucchini Pizza Casserole
To make these healthy zucchini pizza casserole meal prep bowls, you will need the following ingredients:
- Zucchini: Approximately 4 medium zucchinis, shredded (about 6 cups).
- Eggs: 2 large eggs, lightly beaten to bind the “crust.”
- Cheese: 2 cups of shredded mozzarella, divided, and 1/2 cup of grated Parmesan cheese.
- Flour Alternative: 1/2 cup of almond flour or coconut flour to help absorb moisture.
- Marinara Sauce: 1 cup of your favorite low-sugar pizza sauce or marinara.
- Toppings: 1/2 cup of mini pepperoni slices, diced bell peppers, and sliced black olives.
- Seasonings: 1 teaspoon of dried oregano, 1 teaspoon of garlic powder, and a pinch of salt and black pepper.
Step-by-Step Instructions
Follow these steps to create the perfect meal prep containers:
- Prepare the Zucchini: Start by shredding the zucchini using a box grater or food processor. Place the shredded zucchini in a clean kitchen towel and squeeze out as much liquid as possible. This is the most important step to prevent a watery casserole.
- Create the Base: In a large mixing bowl, combine the squeezed zucchini, beaten eggs, Parmesan cheese, almond flour, and half of the mozzarella cheese. Stir in the garlic powder, oregano, salt, and pepper.
- Initial Bake: Press the zucchini mixture into a greased 9×13 inch baking dish or directly into oven-safe meal prep glass containers. Bake at 400 degrees Fahrenheit (200 degrees Celsius) for 15 to 20 minutes until the base is set and slightly golden.
- Add Layers: Remove from the oven and spread the marinara sauce evenly over the zucchini base. Sprinkle the remaining mozzarella cheese and add your pepperoni, peppers, and olives.
- Final Melt: Return the dish to the oven for another 10 to 15 minutes, or until the cheese is bubbly and beginning to brown.
- Portion: Let the casserole cool for at least 10 minutes before slicing into portions and placing them into your meal prep bowls.
Expert Tips for the Best Results
To ensure your healthy zucchini pizza casserole meal prep bowls turn out perfectly every time, keep these tips in mind. First, do not skimp on the squeezing process; zucchini holds an incredible amount of water that will release during baking if not removed beforehand. Second, if you prefer a crispier “crust,” try pre-salting the shredded zucchini and letting it sit for 10 minutes before squeezing it. This draws out even more moisture. Lastly, use a high-quality marinara sauce that isn’t too thin, as a thicker sauce provides a better mouthfeel and prevents the dish from feeling runny.
Variations and Substitutions
One of the best things about this recipe is its versatility. You can easily customize the toppings to fit your preferences:
- Meat Lovers: Add cooked Italian sausage, crispy bacon bits, or diced ham.
- Vegetarian: Load up on mushrooms, spinach, red onions, and artichoke hearts.
- Dairy-Free: Substitute the mozzarella and Parmesan with your favorite vegan cheese shreds.
- Spicy: Add a sprinkle of red pepper flakes or sliced jalapeños for a kick.
Serving Suggestions
While these bowls are a complete meal on their own, you can elevate the experience with a few simple sides. A crisp green side salad with a light balsamic vinaigrette provides a refreshing contrast to the cheesy casserole. If you aren’t strictly low-carb, a side of toasted garlic bread is perfect for soaking up any extra sauce. For an extra boost of flavor, garnish the bowls with fresh basil leaves or a drizzle of balsamic glaze right before eating.
Storage, Freezing, and Reheating
Storage: Store the portioned bowls in airtight containers in the refrigerator for up to 4 to 5 days.
Freezing: This casserole freezes surprisingly well. Wrap individual portions tightly in plastic wrap and then place them in a freezer-safe bag. They will stay fresh for up to 3 months. Thaw in the refrigerator overnight before reheating.
Reheating: For the best texture, reheat in the oven or an air fryer at 350 degrees Fahrenheit until warmed through. If you are in a rush, the microwave works well; simply heat for 1.5 to 2 minutes on high.

Frequently Asked Questions
Can I use frozen zucchini for this recipe?
Yes, you can use frozen shredded zucchini, but you must thaw it completely and squeeze out the excess water very thoroughly. Frozen zucchini tends to be even more watery than fresh, so extra care is needed during the drying process.
Is this recipe gluten-free?
As long as you use almond flour or a certified gluten-free flour blend and ensure your marinara sauce is gluten-free, this recipe is naturally gluten-free and safe for those with celiac disease or gluten sensitivities.
How do I stop the casserole from being soggy?
The secret lies in the moisture removal. Squeeze the zucchini until no more liquid comes out. Additionally, baking the zucchini base first (the “blind bake”) helps solidify the structure before you add the wet sauce and toppings.
