Zucchini Pizza Casserole is a low-carb, cheesy, and veggie-loaded bake that captures all the bold flavors of pizza — without the crust. Perfect for keto dinners, meal prep, or family pizza night.
4 cups shredded zucchini
2 eggs, beaten
1 cup shredded mozzarella (for crust)
¼ cup grated Parmesan
1 lb ground beef or sausage
1½ cups marinara or pizza sauce (low sugar)
1½–2 cups shredded mozzarella (for topping)
½ tsp garlic powder
Salt and pepper to taste
Optional toppings: pepperoni, olives, bell peppers, mushrooms
Preheat oven to 400°F. Grease a 9×13 baking dish.
Shred zucchini and squeeze out moisture using a towel.
Mix zucchini, eggs, 1 cup mozzarella, Parmesan, garlic powder, salt, and pepper. Press into the dish and bake for 20–25 minutes.
Brown the ground meat in a skillet. Add sauce and simmer for 5 minutes.
Spread meat sauce over baked crust. Top with remaining mozzarella and desired toppings.
Bake for 15–20 more minutes, until bubbly. Let rest before slicing.
