2 cloves garlic, minced

Pizza Layer

1½ cups pizza sauce or marinara sauce

How to Make Zucchini Pizza Casserole

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C).

Lightly grease a 9×13 inch baking dish to prevent sticking.

Step 2: Prepare the Zucchini

Zucchini contains a lot of moisture, so it’s best to remove some water before baking.

Slice or dice the zucchini.
Sprinkle lightly with salt.
Let sit for 10 minutes, then pat dry with paper towels.

This step helps keep the casserole from becoming watery.

Step 3: Cook the Meat

Heat a skillet over medium heat.

Add ground beef or sausage.
Cook until browned.
Add diced onion and garlic.
Cook for 3–4 minutes until fragrant.

Drain excess fat if necessary.

Step 4: Combine the Filling

Stir into the skillet:

Pizza sauce
Italian seasoning
Salt and pepper

Add the zucchini and mix everything together so the vegetables are coated with sauce.

Step 5: Assemble the Casserole

Transfer the mixture into the prepared baking dish.

Top with:

Mozzarella cheese
Parmesan cheese
Pepperoni slices or other toppings

Step 6: Bake

Bake uncovered for 25–30 minutes until the cheese is melted and bubbly.

For a golden top, broil for 2–3 minutes at the end.

Step 7: Cool and Serve

Allow the casserole to rest for 5–10 minutes before serving.

This helps the layers set and makes slicing easier.

Tips for the Best Zucchini Pizza Casserole

Salt and drain zucchini first to prevent excess moisture.
Use Italian sausage for extra pizza flavor.
Freshly shredded mozzarella melts better than pre-shredded.
Let the casserole rest before serving so it holds together nicely.
