Equipment

  • Box grater (or food processor)
  • Mixing bowls
  • Cheesecloth or clean towel (for draining zucchini)
  • Baking dish (9x13 inch)
  • Parchment paper
  • Oven

Ingredients
  

  • 4 cups zucchini, grated
  • 2 large eggs
  • 1 cup shredded mozzarella cheese (for crust)
  • ½ cup grated Parmesan cheese
  • 1 tsp salt
  • 1 cup pizza sauce
  • 2 cups shredded mozzarella cheese (for topping)
  • ½ cup sliced pepperoni or other toppings (optional)
  • 1 tsp Italian seasoning

Instructions
 

  • Prep Zucchini: Grate zucchini and place in a towel. Sprinkle with salt, let sit 10 minutes, then squeeze out excess moisture.
  • Make Crust: Mix zucchini with eggs, 1 cup mozzarella, and Parmesan. Spread mixture evenly in a parchment-lined baking dish.
  • Bake Crust: Bake at 400°F (200°C) for 20 minutes until set and lightly golden.
  • Add Sauce & Toppings: Spread pizza sauce over baked crust. Add toppings of choice (pepperoni, mushrooms, peppers, olives). Sprinkle with 2 cups mozzarella and Italian seasoning.
  • Bake Again: Return to oven and bake for 15–20 minutes until cheese is bubbly and golden.
  • Cool & Serve: Let casserole cool for 5 minutes before slicing.

Notes

  • Drain zucchini thoroughly to avoid a watery base.
  • Use parchment paper for easy removal and cleaner slices.
  • Customize with vegetarian toppings, spicy jalapeños, or reduced-fat cheese.
  • Store in fridge up to 3 days; freeze slices individually for longer storage.
  • Reheat in oven for best texture; microwave for quick reheating.
