Step‑by‑Step Instructions for Zucchini Pizza Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This crucial step ensures that the Zucchini Pizza Casserole bakes evenly, allowing the flavors to meld beautifully while achieving that golden finish. Make sure your oven is thoroughly heated to get the best results, so it’s ready for the delicious crust you’re about to create.

Step 2: Prepare the Zucchini
In a large mixing bowl, toss 4 cups of shredded zucchini with 1/2 teaspoon of salt. Let the mixture rest for about 10 minutes. This process draws out excess moisture from the zucchini, preventing a soggy crust. As the salt works its magic, you can gather your other ingredients and prep your workspace for an efficient cooking experience.

Step 3: Drain the Zucchini
After resting, take a clean kitchen towel and transfer the salted zucchini into it. Squeeze firmly to extract as much liquid as possible, ensuring your Zucchini Pizza Casserole crust sets up nicely. The goal is to achieve a dry mixture, which can then hold together well during baking.

Step 4: Mix the Crust Ingredients
In the same bowl, combine the drained zucchini with 2 large eggs, 1/2 cup of grated Parmesan cheese, and half of the shredded mozzarella cheese. Mix until well-combined, creating a moist, yet thick mixture. This comforting blend is the base of your casserole, setting the stage for a flavorful filling to follow.

Step 5: Form the Crust
Lightly grease a 9×13-inch baking dish with cooking spray or olive oil. Evenly press the zucchini mixture into the bottom of the dish, forming a crust approximately 1/2 inch thick. Ensure that you cover the entire base for even cooking and to create a sturdy foundation for your Zucchini Pizza Casserole.

Step 6: Bake the Crust
Place the prepared baking dish in the preheated oven and bake the crust for about 20 minutes, or until it’s lightly browned. Check for a firm texture around the edges, indicating it’s ready for the filling. This step is essential to achieve a delightful crunch that complements the toppings.

Step 7: Cook the Filling
While the crust is baking, heat a skillet over medium heat. Add 1 pound of ground beef and 1/2 cup of chopped onion, browning them together for about 6–8 minutes until the meat is no longer pink and the onions become translucent. This savory filling will elevate your Zucchini Pizza Casserole to new heights with rich flavor.

Step 8: Add Vegetables
Once the beef is fully cooked, stir in 2 cups of pizza sauce, 1 chopped green bell pepper, 1/2 cup of sliced mushrooms, 1/2 teaspoon of dried oregano, 1/2 teaspoon of garlic powder, and 1/4 teaspoon of black pepper. Let this delicious mixture simmer for about 5 minutes. The aromas will be irresistible, giving you a sneak peek of the flavor-packed casserole to come.

Step 9: Assemble the Casserole
Remove the crust from the oven once baked. Spread the beef and vegetable mixture evenly over the hot crust, ensuring every bite of zucchini is infused with those savory flavors. This layering technique helps create a harmonious blend of textures and tastes in your Zucchini Pizza Casserole.

Step 10: Add Cheese Toppings
Sprinkle the remaining mozzarella and 1 cup of shredded cheddar cheese generously over the beef mixture. This cheesy layer will melt beautifully, adding an enticing gooeyness. Make sure to distribute the cheese evenly for a perfectly topped casserole that’s golden and bubbling by the time it’s done baking.

Step 11: Final Bake
Return the assembled Zucchini Pizza Casserole to the oven and bake for an additional 20 minutes, or until the cheese is melted and bubbly. Keep an eye on the casserole in the last few minutes to ensure the cheese reaches a beautiful, golden color, enhancing both the presentation and flavor of your dish.

Step 12: Cool and Serve
After baking, take the casserole out of the oven and let it cool for a few minutes. This resting time makes it easier to slice. As you cut into this delightful Zucchini Pizza Casserole, the layers will reveal themselves, ready for serving. Your family will love digging into this wholesome meal!

Very! Once cooled, store any leftovers in an airtight container in the refrigerator for up to 3-4 days. If you find that you’re not able to finish them within that time, you can wrap portions tightly in plastic wrap or foil, then place them into a freezer-safe container. This way, they’ll stay fresh in the freezer for up to three months!

How do I prevent a soggy crust?
To achieve a splendid crust, it’s crucial to squeeze out as much moisture from the zucchini as possible after salting it. I recommend letting the zucchini rest for 10 minutes before draining it thoroughly in a clean towel. Ensuring you also pre-bake the crust helps create that golden-brown texture you desire.

Absolutely! This casserole is both kid-friendly and customizable, so it can cater to various dietary preferences.
