Step‑by‑Step Instructions for Zucchini Pizza Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This temperature is ideal for achieving that golden, bubbly finish on your Zucchini Pizza Casserole. While the oven heats up, gather your ingredients and prepare to create a deliciously comforting meal that everyone will love.

Step 2: Prepare the Zucchini
In a mixing bowl, combine the shredded zucchini and salt, allowing it to sit for 10 minutes. This process draws out moisture, ensuring a firm crust. You’ll see the zucchini release water as it rests. It’s essential to this step for a perfect base that doesn’t turn soggy during baking.

Step 3: Squeeze Excess Moisture
After letting the zucchini sit, take a clean kitchen towel and squeeze out as much moisture as possible. Once well-drained, mix the zucchini with eggs, grated Parmesan, and half of the shredded mozzarella. This combination creates a flavorful and cohesive crust for your Zucchini Pizza Casserole, setting the groundwork for deliciousness.

Step 4: Form the Crust
Grease a 9×13-inch baking dish with cooking spray or olive oil. Carefully press the zucchini mixture into the dish evenly to form a crust. Ensure it reaches all edges and is compact for a sturdy base. Bake this delightful crust in the preheated oven for 20 minutes, until it appears set and golden brown.

Step 5: Cook the Beef Mixture
While the crust is baking, heat a skillet over medium heat and add the ground beef along with chopped onion. Cook for about 5-7 minutes, stirring occasionally, until the beef is browned and the onion becomes translucent. Make sure to drain any excess fat, leaving you with a rich and savory base for the casserole.

Step 6: Add the Vegetables and Seasoning
To the skillet, stir in the pizza sauce, diced green bell pepper, sliced mushrooms, oregano, garlic powder, and black pepper. Cook everything together for another 5 minutes, allowing the flavors to meld beautifully. You’ll know it’s ready when the vegetables are tender and well-coated in sauce, enhancing that comforting pizza flavor.

Step 7: Assemble the Casserole
Once the zucchini crust has finished baking, remove it from the oven and evenly spread the savory beef mixture over the top. This layer adds heartiness to your Zucchini Pizza Casserole, making it satisfying and filling. Gently press the mixture down with a spatula for an even bite.

Step 8: Add the Cheese Toppings
To finish, sprinkle the remaining mozzarella and all of the shredded cheddar cheese evenly over the beef layer. The blend of cheeses will melt into a gooey, delightful topping that enhances the flavor and texture. Now, pop the casserole back into the oven for an additional 20 minutes until the cheese is beautifully melted and bubbly.

Step 9: Cool and Serve
Remove the Zucchini Pizza Casserole from the oven and let it rest for a few minutes before slicing. This step allows the layers to set, ensuring cleaner slices. You’ll reveal a hearty, cheesy dish that’s perfect for sharing; serve warm and enjoy the joy of a comforting, homemade meal!
