How to Cook Zucchini Pizza Casserole: A Step-by-Step Guide
- Prepare the Zucchini: Preheat your oven to 400°F (200°C). Place the grated zucchini in a colander and sprinkle with salt. Let it sit for 10 minutes to draw out excess moisture. After 10 minutes, squeeze the zucchini in a clean kitchen towel or paper towels to remove as much liquid as possible.
- Make the Zucchini Crust: In a large bowl, combine the grated zucchini, eggs, 1 cup shredded mozzarella cheese, grated Parmesan cheese, dried oregano, dried basil, and garlic powder. Mix well to combine.
- Bake the Crust: Press the zucchini mixture into a greased 9x13-inch baking dish to form an even layer. Bake in the preheated oven for 20 minutes, or until the crust is set and lightly golden.
- Add the Sauce and Toppings: Remove the zucchini crust from the oven and spread the pizza sauce evenly over the top. Sprinkle with 1 cup of shredded mozzarella cheese and add your favorite pizza toppings.
- Bake Again: Return the casserole to the oven and bake for an additional 15-20 minutes, or until the cheese is melted and bubbly and the toppings are cooked to your liking.
- Cool and Serve: Allow the casserole to cool for 5 minutes before slicing and serving.
Common Mistakes to Avoid
- Not Draining the Zucchini: Properly draining the zucchini is crucial to avoid a watery casserole. Squeeze out as much moisture as possible.
- Overloading the Toppings: Too many toppings can make the casserole heavy and soggy. Keep it balanced.
- Skipping Pre-baking the Crust: Pre-baking the zucchini crust ensures it sets properly and holds together.
