Step‑by‑Step Instructions for Zucchini Pizza Casserole
Step 1: Preheat Oven
Begin by preheating your oven to 400°F (200°C). This ensures a perfectly baked Zucchini Pizza Casserole right from the start. As the oven heats, gather your ingredients and prepare your workspace, making sure everything is ready for quick assembly.
Step 2: Prepare Zucchini
Take your shredded zucchini and toss it with salt in a bowl. Let it rest for about 10 minutes to draw out excess moisture. During this time, you’ll notice the zucchini wilts slightly, which is exactly what you want for a sturdy crust in your casserole.
Step 3: Drain Zucchini
After the resting period, it’s time to squeeze out the moisture. Using a clean kitchen towel, wrap the salted zucchini and twist to remove as much liquid as possible. This step is crucial to prevent a soggy crust in your delightful Zucchini Pizza Casserole.
Step 4: Mix Crust
In a large bowl, combine the drained zucchini with eggs, grated Parmesan cheese, and half of the shredded mozzarella. Stir until everything is well mixed and holds together. This mixture will form a delicious, sturdy crust for your casserole, so make sure all ingredients are fully incorporated.
Step 5: Form Crust
Take the zucchini mixture and press it evenly into a greased 9×13-inch baking dish. Use your hands or a spatula to ensure an even layer, as this will support the filling nicely. Aim for a crust that is about ½ inch thick for optimal texture.
Step 6: Bake Crust
Place the dish in your preheated oven and bake for 20 minutes, or until the crust turns golden brown and feels firm to the touch. This pre-baking step is essential for creating a crisp base for your Zucchini Pizza Casserole, preventing any sogginess from the toppings.
Step 7: Cook Filling
While the crust is baking, prepare your filling. In a skillet, sauté ground beef and chopped onion over medium-high heat until the beef is browned and the onion is translucent, about 5-7 minutes. Stir in pizza sauce, chopped bell pepper, mushrooms, oregano, garlic powder, and black pepper; let it simmer for an additional 5 minutes.
Step 8: Assemble Casserole
Once your crust is baked and golden, spread the savory beef mixture evenly over the top. Use a spatula to ensure it covers the entire crust, allowing for every slice of your Zucchini Pizza Casserole to be packed with flavor.
Step 9: Add Cheese
Sprinkle the remaining mozzarella cheese and the shredded cheddar cheese generously over the filling. This cheese layer will melt beautifully during the final bake and give your casserole that irresistible gooey texture everyone loves.
Step 10: Final Bake
Return the casserole to the oven and bake for another 20 minutes or until the cheese is bubbly and golden. You’ll know it’s ready when your kitchen is filled with the comforting aroma of pizza and the cheese is perfectly melty.
Step 11: Cool and Serve
After baking, allow the Zucchini Pizza Casserole to cool for a few minutes on a wire rack. This helps the layers settle, making it easier to slice. Cut into squares and serve warm, ready for everyone to dig in and enjoy a healthier take on pizza!

Make Ahead Options

You can prepare the crust up to 24 hours in advance; just complete steps 1 through 6 and cover the pan with plastic wrap before refrigerating.
