How to Make Zucchini Pizza Casserole

Step 1: Prepare the zucchini crust

Start by preheating your oven to 400°F (200°C) — this will create the perfect environment for your crust to bake evenly. Combine the shredded zucchini with salt in a large bowl and let it rest for 10 minutes to release excess moisture. This step is crucial to prevent a soggy crust. Then, squeeze out as much water as you can using a kitchen towel or cheesecloth; trust me, dry zucchini means a crust that holds together beautifully after baking.

Step 2: Mix the crust ingredients

After draining, mix the zucchini with eggs, Parmesan cheese, and half of the mozzarella cheese. This mixture binds all those fresh zucchini strands with cheesy goodness, shaping the base for your casserole. Press this evenly into a greased 9×13-inch baking dish, forming a sturdy layer that will hold all the delicious toppings.

Step 3: Bake the crust

Pop your crust into the oven and bake for about 20 minutes, or until it sets and turns a lovely golden brown. The aroma at this point is heavenly, with the Parmesan and mozzarella melting into the zucchini to create a crispy, flavorful foundation.

Step 4: Prepare the savory beef topping

While the crust bakes, brown the ground beef with chopped onion in a skillet over medium heat until no longer pink, draining off any excess fat afterward. Stir in pizza sauce, green bell pepper, mushrooms, oregano, garlic powder, and black pepper. Let this simmer for about 5 minutes to blend the flavors and soften the vegetables, creating the perfect saucy topping for your Zucchini Pizza Casserole.

Step 5: Assemble and bake the casserole

Once the crust is ready, evenly spread the beef mixture over it, then sprinkle with the remaining mozzarella and all of the cheddar cheese. Return the casserole to the oven and bake another 20 minutes until the cheese melts into a bubbly, golden blanket. The contrast between the crispy zucchini crust and rich, cheesy topping will have you eager for the first bite.

Step 6: Cool and serve

Remove your masterpiece from the oven and let it cool for a few minutes to set. This resting time helps the layers slice neatly so you can serve perfect squares of cheesy, savory comfort. Then dig in and enjoy your incredible Zucchini Pizza Casserole!

Garnishes

Topping your casserole with fresh herbs like chopped basil or parsley adds a pop of color and fresh brightness that complements the richness. A light sprinkle of crushed red pepper flakes can provide a kick of heat for those who love a little spice. You can also drizzle a touch of extra virgin olive oil or a sprinkle of Parmesan for a finishing flourish.

Side Dishes

This casserole is quite filling, but pairing it with a crisp green salad or steamed vegetables keeps the meal balanced and colorful. For a heartier spread, roasted garlic bread or a simple arugula salad with lemon vinaigrette makes a fantastic accompaniment, perfect for soaking up any extra pizza sauce.

Creative Ways to Present

Try serving the Zucchini Pizza Casserole in individual ramekins for a personalized touch at dinner parties or family gatherings.

Make Ahead and Storage

Storing Leftovers

Place leftover Zucchini Pizza Casserole in an airtight container and refrigerate for up to 3 days. The flavors will actually meld and improve slightly after a day, making for a tasty second-day meal. Just make sure to cool it completely before sealing to preserve freshness.

Freezing

This casserole freezes beautifully. Wrap individual slices or the entire dish tightly with plastic wrap and aluminum foil, then store in the freezer for up to 2 months. Thaw overnight in the refrigerator before reheating to maintain texture and flavor.

Reheating

Reheat leftovers either in the oven at 350°F (175°C) for about 15–20 minutes or until warmed through, or use the microwave for a quicker option, though the oven method keeps the crust crispier. For freezer-thawed casseroles, let them come to room temperature first before reheating.
