How to Make Zucchini Pizza Casserole
-
Preheat the oven to 400°F (200°C). This step ensures your casserole bakes evenly and develops a beautiful golden crust.
-
Toss the shredded zucchini with salt and let it rest for 10 minutes. This will help draw out excess moisture, preventing a soggy crust.
-
Drain the zucchini thoroughly using a kitchen towel. Be sure to squeeze out as much water as possible to achieve that perfect crust texture.
-
Mix the drained zucchini with eggs, Parmesan cheese, and half of the mozzarella until well combined. The eggs will help bind the ingredients together for a sturdy base.
-
Press the zucchini mixture into a greased 9×13-inch baking dish to form the crust. Ensure you spread it evenly across the bottom for consistent cooking.
-
Bake the crust for 20 minutes until it is set and lightly browned. This pre-baking allows it to hold up well under the filling.
-
Brown the ground beef and onions in a skillet over medium heat, for about 6-8 minutes. Drain any excess fat to keep the casserole from becoming greasy.
-
Add the pizza sauce, green bell pepper, mushrooms, oregano, garlic powder, and black pepper to the beef; simmer for 5 minutes. This allows the flavors to mingle nicely.
-
Spread the beef mixture evenly over the baked zucchini crust. Make sure to cover the crust completely for an even flavor with every bite.
-
Top with the remaining mozzarella and cheddar cheeses. This melty layer brings everything together with delicious, cheesy goodness.
-
Bake for an additional 20 minutes until the cheese is melted and bubbly. You’re looking for that enticing golden hue on top!
-
Allow to cool for a few minutes before slicing and serving. This helps the casserole set, making it easier to cut into portions.
Optional: Garnish with fresh basil or oregano for a fragrant finish.
