How to Make Zucchini Pizza Casserole

1. Prepare the Zucchini Crust

Preheat your oven to 400°F (200°C).
Toss the shredded zucchini with salt and let it sit for about 10 minutes. This step helps draw out excess moisture.
Using a clean kitchen towel, squeeze out as much liquid as possible. This is key to avoiding a soggy crust.

2. Mix and Form the Crust

In a mixing bowl, combine the drained zucchini, eggs, Parmesan cheese, and half of the mozzarella cheese.
Grease a 9×13-inch baking dish and press the mixture evenly into the bottom to form a crust layer.

3. Bake the Crust

Bake for about 20 minutes, or until the crust is set and lightly golden.
Tip: A firm crust ensures your casserole slices hold together nicely.

4. Cook the Filling

In a skillet over medium heat, cook the ground beef and chopped onion until browned, about 7–10 minutes. Drain excess fat if needed.
Stir in the pizza sauce, bell pepper, mushrooms, oregano, garlic powder, and black pepper. Mix well and let simmer briefly.

5. Assemble the Casserole

Spread the beef and sauce mixture evenly over the baked zucchini crust.
Sprinkle the remaining mozzarella cheese and cheddar cheese over the top.

6. Bake Until Bubbly

Return the dish to the oven and bake for another 20 minutes, or until the cheese is melted, bubbly, and slightly golden.

7. Cool and Serve

Let the casserole cool for about 10 minutes before slicing. This helps it set and makes serving easier. Serve warm and enjoy!

Tips for Success

• Always drain zucchini thoroughly to prevent a watery base
• Let the crust bake fully before adding toppings
• Use freshly shredded cheese for better melting
• Allow the casserole to rest before slicing for clean pieces
