Ingredients
Prep Time: 15 minutes
Cook Time: 40 minutes
Total Time: 55 minutes
Servings: 6
- 4 cups shredded zucchini
- 1/2 teaspoon salt
- 2 large eggs
- 1/2 cup grated Parmesan cheese
- 2 cups shredded mozzarella cheese, divided
- 1 cup shredded cheddar 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
The main ingredient, zucchini, not only boosts the nutrition but also keeps the dish moist. The combination of cheeses provides creaminess and depth, while the ground beef adds heartiness. Feel free to customize the toppings based on your family’s preferences!

Step-by-Step Instructions
- Preheat your oven to 400°F (200°C).
- In a large bowl, combine the shredded zucchini and salt. Allow the mixture to sit for 10 minutes to release moisture.
- Squeeze out excess moisture from the zucchini using a clean kitchen towel or cheesecloth; this step is crucial to avoid a soggy crust.
- Mix the drained zucchini with eggs, Parmesan cheese, and half of the mozzarella cheese until combined.
- Grease a 9×13-inch baking dish and press the zucchini mixture evenly into the bottom to form a crust.
- Bake the crust for 20 minutes or until set and lightly browned.
- In a skillet, brown the ground beef with chopped onion until no longer pink, about 5-7 minutes. Drain any excess fat to keep the casserole from becoming greasy.
- Stir in pizza sauce, chopped bell pepper, mushrooms, oregano, garlic powder, and black pepper. Cook for another 5 minutes to meld the flavors.
- Spread the beef mixture evenly over the zucchini crust.
- Sprinkle remaining mozzarella cheese and all of the cheddar cheese on top.
- Return to oven and bake for another 20 minutes until cheese is melted and bubbly. Keep an eye on it to ensure the cheese doesn’t burn.
- Allow cooling for a few minutes before slicing and serving. This will make it easier to cut clean pieces.
Delicious Ways to Serve This Casserole
This casserole is incredibly versatile and can be served in various ways. For a complete meal, consider pairing it with a simple green salad dressed with a light vinaigrette. A side of garlic bread can also complement the flavors beautifully and add a comforting touch. If you’re hosting a gathering, this dish makes for a fantastic potluck item, as it feeds a crowd and is easy to transport. For drinks, a chilled lemonade or iced tea can refreshingly balance the richness of the cheese and meat.
How to Store and Reheat Leftovers
If you find yourself with leftovers, you’re in luck! This Zucchini Pizza Casserole stores very well. Allow the casserole to cool completely and then cover it tightly with plastic wrap or aluminum foil. You can store it in the fridge for up to 3-4 days. If you want to prolong the life of your casserole, consider freezing individual portions. Wrap them tightly and freeze for up to 2 months.
When it’s time to reheat, preheat your oven to 350°F (175°C). Cover the casserole with foil and heat for about 20-25 minutes or until warmed through. For individual portions, microwave on high for 1-2 minutes, checking frequently to ensure even heating.
Essential Cooking Tips for Success
Achieving the perfect Zucchini Pizza Casserole comes with a few handy tips. First, make sure to thoroughly squeeze out any excess moisture from the zucchini; this step ensures the crust holds together and doesn’t become soggy. Additionally, feel free to experiment with different proteins—use turkey or chicken for a lighter option. Keeping the ground meat in bite-sized chunks instead of crumbling it too finely will give the casserole more texture.
Lastly, don’t skip the resting time after baking! Allowing the casserole to cool slightly before cutting makes for cleaner slices and better presentation.
Fun Variations to Try
This Zucchini Pizza Casserole is quite forgiving and lends itself to various modifications. If you’re in the mood for a twist, consider adding different vegetables like spinach, olives, or even jalapeños for some heat. For a meatless version, simply replace the ground beef with a medley of roasted vegetables or a plant-based meat substitute.
You can also change up the cheeses. Try adding feta for a tangy punch or pepper jack for a little kick. If you’re feeling adventurous, drizzle some pesto on top before baking for added flavor.
