Ingredients Needed For Zucchini Pizza Casserole

I love making this in the summer with fresh zucchini out of my garden. Yummy! The rest is simple ingredients that you either have on hand or are easily found at your local grocery store. Here is what you’ll need to make Zucchini Pizza Casserole:

• Zucchini: Fresh zucchini is the star here, forming the base of the cheesy zucchini crust.
• Salt and Black Pepper: Adds flavor and helps to draw out excess moisture from the shredded zucchini.
• Large Eggs: Binds the zucchini mixture together.
• Mozzarella Cheese: Used in both the crust and on top—because you can never have too much cheese.
• Cheddar Cheese: Adds a sharp, rich flavor to the crust.
• Parmesan Cheese: For that classic Italian touch in the crust.
• Pizza Sauce: Your choice of marinara sauce or Italian tomato pizza sauce.
• Pepperoni Slices: Classic topping, but feel free to add your personal favorites.
• Fresh Basil: Adds a fresh, herbaceous note as a garnish.

Variations

• Cheeses: Swap cheddar for Monterey Jack or try part-skim mozzarella cheese for a lighter option.
• Toppings: Mix it up with cooked Italian sausage, black olives, bell peppers, onions, artichoke, spinach, mushrooms, or red pepper flakes.
• Crust: If you’re feeling adventurous, replace the zucchini with cauliflower for a different take.
• Protein: Try adding cooked shredded chicken, ground turkey, or brown ground beef for a heartier dish.

Throwing this dish together doesn’t take very much prep work! Simply grate the zucchini and cheeses, combine with egg and put it in a baking dish, and bake.

Step 2: Prep Zucchini + Make Pizza Crust

Grate zucchini and measure out 4 cups. Sprinkle salt over zucchini and let sit for 10 minutes. Ring out zucchini in a clean kitchen towel or paper towels to remove any excess liquid.
