How to Make Zucchini Pizza Casserole
Ready to get cooking? Follow these simple steps to create your very own Zucchini Pizza Casserole:
- Preheat your oven to 400°F (200°C).
- In a large bowl, combine the shredded zucchini and salt. Let it sit for 10 minutes to release excess moisture.
- After 10 minutes, use a clean kitchen towel or cheesecloth to squeeze out as much moisture as possible from the zucchini.
- In the same bowl, mix the drained zucchini with the eggs, Parmesan cheese, and half of the mozzarella cheese. This will form the crust mixture.
- Grease a 9×13-inch baking dish. Press the zucchini mixture evenly into the bottom of the dish to create your crust.
- Bake the crust in the preheated oven for 20 minutes, or until it’s set and lightly browned.
- While the crust is baking, brown the ground beef with the chopped onion in a skillet over medium heat until the beef is no longer pink. Drain any excess fat.
- Stir in the pizza sauce, green bell pepper, mushrooms, oregano, garlic powder, and black pepper. Cook for another 5 minutes, stirring occasionally.
- Once the crust is ready, spread the beef mixture evenly over the zucchini crust.
- Sprinkle the remaining mozzarella cheese and all of the cheddar cheese over the top.
- Return the casserole to the oven and bake for an additional 20 minutes, or until the cheese is melted and bubbly.
- Remove from the oven and allow the casserole to cool for a few minutes before slicing and serving.
