Ingredients You’ll Need

The beauty of this casserole is in its simplicity. Each ingredient plays a crucial role: zucchini brings moisture and freshness, cheeses offer gooey, melty richness, and the beef and sauce deliver hearty, savory depth.

• 4 cups shredded unpeeled zucchini: Using unpeeled zucchini keeps it colorful and adds a bit of texture.
• 1/2 teaspoon salt: Helps draw out moisture from the zucchini to prevent sogginess.
• 2 large eggs: These bind the zucchini and cheese mixture together perfectly.
• 1/2 cup grated Parmesan cheese: Adds a nutty, sharp punch that enhances the overall flavor.
• 2 cups shredded part-skim mozzarella cheese, divided: Provides that classic melty, stretchy pizza cheese texture.
• 1 cup shredded cheddar cheese, divided: Offers a tangy, robust flavor depth that complements the mozzarella.
• 1 pound ground beef: Adds hearty protein and a savory base for the casserole.
• 1/2 cup chopped onion: Infuses sweetness and aromatic complexity when cooked with the beef.
• 1 can (15 ounces) Italian tomato sauce: Brings the signature pizza flavor with rich, tangy tomato goodness.
• 1 medium green or sweet red pepper, chopped: A pop of color and a slight crunch to finish the dish bright.

How to Make Zucchini Pizza Casserole

Step 1: Prepare the Zucchini Base

Start by preheating your oven to 400 degrees Fahrenheit because this casserole needs a good hot oven for that perfect bake. Place the shredded zucchini into a colander, sprinkle it generously with salt, and let it sit for about 10 minutes. This step is essential because it helps pull excess moisture out of the zucchini, preventing the casserole from becoming watery later.

Step 2: Mix and Bake the Veggie and Cheese Layer

After your zucchini has released its moisture, firmly squeeze it dry using a clean kitchen towel or paper towels. Then combine it in a bowl with the eggs, Parmesan cheese, and half of both mozzarella and cheddar cheeses. This mixture forms the savory, cheesy crust of your casserole. Press it evenly into a greased 13×9-inch baking dish and pop it into the oven to bake for 20 minutes. This step sets the base, giving you a crust that’s both tender and flavorful.

Step 3: Cook the Meat Sauce

While the zucchini base is baking, heat a large saucepan over medium heat and cook the ground beef along with the chopped onion. Break the beef into small crumbles as it cooks until it’s no longer pink, then drain off the excess fat for a lighter dish. Stir in the Italian tomato sauce and let it simmer just enough to mingle the flavors beautifully. This hearty tomato and beef mixture will bring the iconic pizza flavor directly into your casserole.

Step 4: Assemble and Finish Baking

Once the zucchini base has baked, spread the meat sauce evenly over top. Sprinkle the rest of the mozzarella and cheddar cheeses on top, then scatter the chopped green or sweet red pepper over everything. Pop the casserole back into the oven and bake for another 20 minutes, or until it’s warmed through and the cheese on top is bubbly and golden. You’ll love the vibrant colors and irresistible aroma coming out of your oven.

How to Serve Zucchini Pizza Casserole

Garnishes

To add an extra fresh and vibrant touch, sprinkle some chopped fresh basil or oregano over each serving. A light drizzle of extra virgin olive oil or a sprinkle of red pepper flakes can also elevate the flavor immensely and lend a beautiful finish.

Side Dishes

This casserole pairs wonderfully with a crisp green salad dressed in lemon vinaigrette or a side of garlic bread to soak up any delicious sauce. Roasted vegetables or even a simple steamed broccoli side can round out the meal too, keeping it balanced and wholesome.

Creative Ways to Present

For parties, consider serving the Zucchini Pizza Casserole in individual ramekins for a charming presentation. You can also cut it into squares and serve as finger food with toothpicks for easy sharing. This casual styling makes it perfect for potlucks or family-style dining.

Make Ahead and Storage

Storing Leftovers

Store any leftover casserole in an airtight container in the refrigerator for up to 3 days. This makes for an incredibly satisfying next-day meal that’s just as flavorful when reheated gently.

Freezing

If you want to keep this fantastic Zucchini Pizza Casserole longer, it freezes beautifully. Wrap it carefully with plastic wrap and foil or place it in a freezer-safe container for up to 2 months. Just thaw it overnight in the fridge before reheating.

Reheating

To reheat, warm individual portions in the microwave or place the casserole in a preheated oven at 350 degrees Fahrenheit until heated through and the cheese is melty again. This refreshes the dish nicely without compromising the texture.
