Step‑by‑Step Instructions for Zucchini Pizza Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This ensures that when your Zucchini Pizza Casserole is ready to bake, the heat is perfectly set to create a golden, crispy crust. While the oven heats, you can prepare the zucchini for the base.
Step 2: Prepare the Zucchini
In a large mixing bowl, combine the 4 cups of shredded zucchini with 1/2 teaspoon of salt. Allow this mixture to sit for about 10 minutes. This will extract excess moisture from the zucchini, preventing a soggy crust later on. You should notice some liquid gathering in the bottom of the bowl.
Step 3: Drain the Zucchini
After the zucchini has rested, take a clean kitchen towel and squeeze out as much moisture as you can from the zucchini. It’s important to get it as dry as possible for a sturdy, delicious crust. Set the drained zucchini aside in the bowl for the next step.
Step 4: Mix the Crust Ingredients
Next, add 2 large eggs, 1/2 cup of grated Parmesan cheese, and half of the 2 cups of shredded mozzarella cheese to the drained zucchini. Mix everything together well until fully combined. This mixture will serve as the flavorful base for your Zucchini Pizza Casserole.
Step 5: Form the Crust
Grease a 9×13-inch baking dish generously with cooking spray or olive oil. Then, evenly press the zucchini mixture into the bottom of the dish to form a compact crust. Ensure it’s spread out evenly for perfect cooking. At this point, your oven should be hot and ready for the next step.
Step 6: Bake the Crust
Place your baking dish in the preheated oven and bake the zucchini crust for about 20 minutes, or until it is set and starting to turn golden brown. This will provide the sturdy base for your casserole and get it ready for the delicious toppings to come.
Step 7: Cook the Ground Beef
While the crust is baking, heat a skillet over medium heat. Add 1 pound of ground beef and 1/2 cup of chopped onion. Cook until the beef is browned and the onion is soft, roughly 5–7 minutes. If there’s excess fat, be sure to drain it off for a lighter dish.
Step 8: Add the Veggies and Sauce
Once the beef and onion are cooked, stir in 2 cups of pizza sauce, along with 1 chopped green bell pepper, 1/2 cup of sliced mushrooms, 1/2 teaspoon dried oregano, 1/2 teaspoon garlic powder, and 1/4 teaspoon black pepper. Cook this mixture for an additional 5 minutes, allowing the flavors to meld wonderfully.
Step 9: Assemble the Casserole
After baking, remove the zucchini crust from the oven. Spread the savory beef and vegetable mixture evenly over the baked zucchini base. This is where your Zucchini Pizza Casserole really starts to take shape, with all those layers of flavor coming together.
Step 10: Add Cheese Toppings
Sprinkle the remaining mozzarella and the full amount of shredded cheddar cheese (1/2 cup) on top of the meat mixture. This will create a gooey, cheesy layer that will melt beautifully as it bakes, giving you that classic pizza finish.
Step 11: Bake Again
Return the assembled casserole to the oven and bake for an additional 20 minutes, or until the cheese is beautifully melted and bubbly. You’ll know it’s done when the cheese is golden and starts to slightly brown—just like a delicious pizza!
Step 12: Cool and Serve
After baking, remove the Zucchini Pizza Casserole from the oven and let it cool for a few minutes. This helps to set the layers for easier slicing. Once cooled slightly, cut it into squares and serve it warm, ready to delight everyone at your table!
Make Ahead Options
These Zucchini Pizza Casseroles are perfect for meal prep enthusiasts! You can prepare the zucchini crust up to 24 hours in advance. Simply complete steps 1-5, then cover the crust tightly with plastic wrap and refrigerate. The topping mixture can also be made ahead—just store it in an airtight container in the fridge for up to 3 days. When you’re ready to bake, assemble the casserole by spreading the topping over the pre-baked crust and adding the cheese before returning it to the oven. This not only saves time but ensures a fresh, delightful meal that’s just as delicious as when made fresh!
