Ingredients
- Prep Time: 20 minutes
- Cook Time: 30 minutes
- Total Time: 50 minutes
- Servings: 6
- 4 cups shredded zucchini
- 1/2 teaspoon salt
- 2 large eggs
- 1/2 cup grated Parmesan cheese
- 1 pound ground beef
- 1/2 cup chopped onion
- 2 cups pizza sauce
- 1 green bell pepper, chopped
- 1/2 cup sliced mushrooms
- 1/2 teaspoon dried oregano
- 1/2 teaspoon garlic powder
- 1/4 teaspoon black pepper
- 2 cups shredded mozzarella cheese
- 1 cup shredded cheddar cheese

Step-by-Step Instructions
- Preheat the oven: Start by heating your oven to 375°F (190°C) to ensure it’s ready for baking.
- Prepare the zucchini: Grate the zucchini and sprinkle it with salt. This step helps to draw out excess moisture from the zucchini. Let it drain in a colander for about 10 to 15 minutes. Afterward, rinse the zucchini under cold water to remove the salt and squeeze out any remaining moisture.
- Mix the base: In a large mixing bowl, combine the drained zucchini with the eggs, grated Parmesan cheese, and a pinch of salt. Mix well until everything is nicely incorporated.
- Cook the filling: In a skillet over medium heat, brown the ground beef with the chopped onion and green bell pepper until the beef is fully cooked and the vegetables are tender. Be sure to drain any excess fat from the skillet.
- Add the sauce: Stir in the pizza sauce, dried oregano, garlic powder, and black pepper into the beef mixture. Let it simmer for a few minutes to let the flavors blend.
- Assemble the casserole: Grease a baking dish with non-stick spray or oil. Spread the zucchini mixture across the base of the dish. Layer the beef mixture evenly on top, add mushrooms over the meat, and finally, sprinkle the shredded mozzarella and cheddar cheese on top.
- Bake the casserole: Place the assembled casserole in the preheated oven and bake for about 30 minutes until the cheese is bubbly and golden brown.
- Serve: Once baked, allow the casserole to cool slightly before slicing. Serve warm and enjoy!
Delicious Ways to Enjoy Your Casserole
This zucchini pizza casserole can be served in various delightful ways. For a complete meal, pair it with a fresh green salad drizzled with balsamic vinaigrette for a wonderful contrast of flavors. Garlic bread or a side of roasted vegetables are also fantastic accompaniments.
If you’re hosting a gathering, consider serving this casserole alongside a selection of appetizers like a charcuterie board or a platter of fresh veggies with dips. A nice glass of red wine or a light beer can complement the dish beautifully, making it perfect for a cozy family dinner or an evening with friends.
Storing and Reheating Tips
If you have leftovers (which is not uncommon, given how delicious this casserole is!), storing it properly can help maintain its flavors and textures. Allow the casserole to cool down to room temperature before transferring it to an airtight container. Store it in the refrigerator for up to 3–4 days.
For longer storage, you can freeze the casserole. Cover it tightly in plastic wrap or aluminum foil and place it in a freezer-safe container. It can be frozen for up to 2-3 months. To reheat, thaw overnight in the refrigerator if frozen. Bake in the oven at 350°F (175°C) until heated through, about 20–25 minutes. A microwave can be used as well but be aware that it can change the texture.

- Ensure the shredded zucchini is well-drained to avoid a soggy casserole.
- Feel free to adjust the seasonings according to your taste. Add more garlic powder or even a pinch of red pepper flakes if you enjoy heat!
