How to Make Zucchini Pizza Casserole
Preheat the oven: Set your oven to 400 °F (200 °C) to ensure it s hot and ready for your casserole. A properly preheated oven is key for a perfectly baked dish!
Toss and rest: In a bowl, mix the shredded zucchini with salt. Allow it to rest for about 10 minutes to draw out excess moisture, which is crucial for a crispy crust.
Squeeze out moisture: After resting, take a clean towel and squeeze the zucchini to remove as much moisture as possible. This step helps prevent a soggy crust!
Mix the crust ingredients: In a mixing bowl, combine the drained zucchini with eggs, Parmesan cheese, and half of the mozzarella. Stir until everything is well blended to form a cohesive crust mixture.
Prepare the baking dish: Grease a 9 13-inch baking dish and evenly press the zucchini mixture into the bottom to create a flat crust.
Bake the crust: Place the dish in the oven and bake for about 20 minutes or until the crust is set and lightly browned. It should have a nice golden color!
Brown the beef: In a skillet over medium heat, brown the ground beef with the chopped onion until it s no longer pink. Be sure to drain any excess fat for a leaner filling.
Add the flavor: Stir in the pizza sauce, bell pepper, mushrooms, oregano, garlic powder, and black pepper. Let the mixture simmer for 5 minutes to allow the flavors to meld beautifully.
Layer the filling: Spread the beef mixture evenly over the baked crust, ensuring every bite is packed with flavor!
Add the cheeses: Heap the remaining mozzarella and all of the cheddar cheese on top of the beef mixture. This will create a gooey, cheesy top that s absolutely irresistible.
Final bake: Return the dish to the oven and bake for an additional 20 minutes, or until the cheese is melted and bubbly. Keep an eye on it, you want that golden goodness!
Cool and serve: Once out of the oven, let the casserole cool for a few minutes before slicing it into squares. This allows the layers to settle and makes serving easier!
