• 4 cups shredded unpeeled zucchini: Provides a moist, veggie-packed base that adds lightness and nutrition.
• 1/2 teaspoon salt: Helps draw excess moisture from the zucchini for better texture.
• 2 large eggs: Act as a binder, holding all the ingredients together beautifully.
• 1/2 cup grated Parmesan cheese: Adds a sharp, nutty flavor that complements the other cheeses.
• 2 cups shredded part-skim mozzarella cheese, divided: Brings that iconic melty, stretchy quality pizza lovers adore.
• 1 cup shredded cheddar cheese, divided: Offers a tangy richness and gorgeous golden color on top.
• 1 pound ground beef: Makes the topping hearty and satisfying with a rich meaty flavor.
• 1/2 cup chopped onion: Adds sweetness and depth when cooked with the beef.
• 1 can (15 ounces) Italian tomato sauce: Provides the perfect zesty, tomatoey sauce layer reminiscent of classic pizza.
• 1 medium green or sweet red pepper, chopped: Lends crunch and vibrant color for visual appeal and freshness.

How to Make Zucchini Pizza Casserole

Step 1: Prep the Zucchini

Begin by shredding your zucchini with skin on for extra nutrients and texture. Sprinkle it with salt and place it in a colander. Let it sit for about 10 minutes to release excess moisture—this is a crucial step that keeps your casserole firm and not watery. Afterward, give it a good squeeze to remove any remaining liquid.

Step 2: Make the Zucchini Cheese Base

Next, combine your well-drained zucchini with eggs, Parmesan cheese, and half of both the shredded mozzarella and cheddar cheeses. Mix thoroughly until everything is evenly incorporated. Press this cheesy zucchini mixture evenly into a greased 13×9-inch or similarly sized baking dish. Pop it into the oven preheated to 400°F and bake for 20 minutes. This creates a savory, firm crust that acts as the perfect pizza foundation.

Step 3: Prepare the Beef Topping

While your zucchini base bakes, cook the ground beef and chopped onion in a large pan over medium heat. Break the meat into small crumbles as it cooks to ensure even browning and texture. Once the beef is no longer pink, drain any excess fat to keep the casserole from becoming greasy. Stir in the Italian tomato sauce until everything is well combined and heated through. This mixture brings the classic pizza sauce flavor that makes this casserole so crave-worthy.

Step 4: Add Cheese and Bake

Remove your zucchini base from the oven and generously spoon the savory beef and sauce mixture over it. Evenly sprinkle the remaining mozzarella and cheddar cheeses on top, then scatter the chopped green or red pepper pieces for a burst of color and fresh crunch. Return the casserole to the oven and bake for an additional 20 minutes, or until it’s heated thoroughly and the cheese has melted into a bubbly, golden topping.

How to Serve Zucchini Pizza Casserole

Garnishes

A sprinkle of fresh basil or oregano leaves adds a fragrant, herbal brightness that perfectly complements the rich, cheesy flavors. You might also add a pinch of crushed red pepper flakes if you like a little kick or a drizzle of good-quality olive oil for a glossy finish.

Side Dishes

This casserole pairs beautifully with a simple green salad tossed in a lemon vinaigrette to cut through the richness. Garlic bread or a crusty baguette are fantastic for soaking up any extra sauce, making the meal feel complete and satisfying.

Creative Ways to Present

Want to impress your guests? Serve the Zucchini Pizza Casserole in individual ramekins or small cast iron skillets for charming, personalized portions. Alternatively, slice it like a traditional pizza and garnish each slice with fresh cherry tomatoes or olives to enhance the pizza experience further.

Make Ahead and Storage

Storing Leftovers

Leftover Zucchini Pizza Casserole keeps wonderfully in the fridge for up to 3 days when covered tightly with plastic wrap or stored in an airtight container. The flavors even deepen after resting, making for delicious next-day meals.

Freezing

If you want to save some for later, this casserole freezes very well. Wrap it securely with foil and plastic wrap, or use a freezer-safe container. It can be frozen for up to 2 months without losing its taste or texture.

Reheating

Reheat leftover or frozen casserole in the oven at 350°F until warmed through and the cheese is once again melty—usually about 20-25 minutes. Avoid microwaving if you want to preserve its texture and avoid sogginess.

FAQs

Can I use zucchini without peeling it?

Absolutely! Keeping the skin on adds extra nutrients, color, and texture to the casserole, making it even more wholesome and beautiful.

Is it possible to make this dish vegetarian?

Can I use different types of cheese?

How do I prevent the zucchini from making the casserole watery?

Salting the shredded zucchini and letting it drain for 10 minutes before squeezing out excess moisture is key. This step ensures your base stays firm during baking.
