How to Make Zucchini Pizza Casserole: Step-by-Step
Step 1: Prepare the Zucchini Base
Start by preheating your oven to 400°F. Place the shredded zucchini in a colander, sprinkle it with kosher salt, and let it sit for about 10 minutes. This step is essential—it helps draw out excess moisture, ensuring a crispy base.
Step 2: Bake the Zucchini Crust
Next, carefully squeeze the zucchini with a kitchen towel to remove any remaining liquid. In a mixing bowl, combine the zucchini with eggs, Parmesan, and half the mozzarella and cheddar cheeses. Press this mixture into a greased 13×9-inch baking dish and bake for 20 minutes. The aroma of the zucchini baking will fill your kitchen!
Step 3: Create the Savory Meat Sauce
While the base bakes, cook the ground beef and onion in a saucepan over medium heat until the meat is no longer pink. Once cooked, drain the meat and stir in the tomato sauce. This hearty meat sauce adds a wonderful depth of flavor to your casserole.
Step 4: Assemble and Bake the Casserole
After the zucchini base is baked, spoon the meat sauce over it. Sprinkle the remaining cheese and diced bell pepper on top. Bake for an additional 20 minutes until everything is hot and bubbly. Your kitchen will smell divine, and you’ll be counting the minutes until you can dig in!
Tips for the Best Zucchini Pizza Casserole
Preventing a Soggy Crust
To prevent a soggy crust, make sure to squeeze as much moisture from the zucchini as possible before baking. This step is crucial for achieving that perfect texture.
Using Frozen Zucchini
If you choose to use frozen zucchini, let it thaw overnight in the refrigerator. Then, squeeze out any excess liquid before incorporating it into the recipe. This ensures the casserole remains deliciously fluffy.
Perfecting the Bake Time and Temperature
Keeping an eye on your bake time is essential. If you notice the cheese starting to brown too quickly, cover it with foil to avoid burning while the center bakes through.

Delicious Vegetarian Options
To satisfy vegetarian diners, skip the meat and load up on vegetables like mushrooms, spinach, or bell peppers instead. They’ll love this flavorful dish!
Garnishing for Extra Flavor
Consider garnishing your casserole with fresh chopped basil or a sprinkle of red pepper flakes for an extra kick. It elevates the dish and adds a burst of freshness.
