Let’s Get Started
This Zucchini Pizza Casserole comes together easily with just a few simple steps. Here’s how to make it:
Step 1: Prepare the Zucchini Base
- Grate the zucchini and place it in a colander. Sprinkle with a little salt and let it sit for about 10 minutes to draw out moisture.
- Squeeze out the excess water using a clean kitchen towel or paper towels. This step ensures your crust isn’t soggy.
- In a bowl, combine the shredded zucchini with eggs, Parmesan cheese, and a bit of mozzarella. Spread this mixture evenly in a greased baking dish to form your crust.
- Bake for about 15–20 minutes at 400°F (200°C) until the crust is lightly golden and set.
Step 2: Cook the Meat and Sauce
- In a skillet, cook the ground beef (or turkey) with chopped onion and garlic until browned.
- Drain any excess fat, then stir in the marinara or pizza sauce. Let it simmer for a few minutes to thicken slightly.
Step 3: Assemble the Casserole
- Spread the meat sauce evenly over the baked zucchini crust.
- Sprinkle a generous layer of mozzarella cheese on top.
- Add your favorite pizza toppings—pepperoni, sliced olives, or diced peppers all work great.
Step 4: Bake and Serve
- Return the casserole to the oven and bake for another 15–20 minutes, or until the cheese is melted and bubbly.
- Let it cool for 5–10 minutes before slicing. This helps the layers hold together beautifully.
And there you have it—a delicious, cheesy, and nutritious meal that’s perfect for any night of the week.
Servings and Pairing
This casserole serves about 6–8 people, depending on portion size. It’s hearty enough to be the main course, but it also pairs beautifully with:
- A fresh side salad – something crisp and tangy like Caesar or Italian salad.
- Garlic roasted vegetables – broccoli, asparagus, or cauliflower add a nice contrast.
- Low-carb garlic bread – perfect for soaking up the extra sauce.
- A glass of red wine or sparkling water with lemon – to elevate the meal experience.
For a cozy weeknight dinner or a casual weekend gathering, this dish makes everyone happy. It’s rich enough for adults but mild enough for kids, making it a versatile addition to your recipe collection.

4. Is this recipe gluten-free?
Yes, this zucchini pizza casserole is completely gluten-free when made with gluten-free sauce and toppings.
