Zucchini Pizza Casserole: A Delicious Low-Carb Summer Favorite

Zucchini Pizza Casserole became my saving grace during the great garden overload of July. One minute you’ve got a modest little green sprout, and the next, your backyard is a zucchini jungle. My grandma would’ve turned them into lasagna by the dozen, but I needed something different—something that whispered “pizza night” without sabotaging my low-carb intentions.

Then a friend passed along this gem from Taste of Home, and it was love at first bite. A golden, cheesy crust made of shredded zucchini, topped with gooey mozzarella, zesty sauce, and all your favorite pizza toppings. It’s now my go-to for lazy weeknights, meal preps, and impressing even the pickiest eaters.

Oh, and if you’re as obsessed with zucchini as I am, be sure to try our easy zucchini fritters for a crispy side dish or explore even more in our summer veggie recipes perfect for garden-fresh zucchini.

What Is Zucchini Pizza Casserole?

Think of it as pizza’s healthier cousin—a hearty, layered casserole with a crust made from shredded zucchini, eggs, and cheese instead of dough. You bake the crust until it sets, then top it with rich pizza or spaghetti sauce, mozzarella, pepperoni (or any toppings you love), and bake again. It’s gluten-free, low-carb, keto-adaptable, and absolutely satisfying.

It’s not pretending to be a pizza replacement—it’s a bold new comfort food in its own right. Perfect for using up garden zucchini and sneaking veggies into dinner without complaints.

How to Make Zucchini Pizza Casserole (Step-by-Step)

Step 1: Prep the Zucchini

• Fresh zucchini? Salt it and let it sit for 20 minutes to release moisture.
• Frozen zucchini? Thaw completely in a colander.
• Always squeeze dry with a clean towel—you want as little water as possible.

Step 2: Make the Crust

• Mix the shredded zucchini with 2 eggs, 1½ cups of mozzarella, Parmesan, garlic, and Italian seasoning.
• Spread into a parchment-lined baking dish.

Step 3: Bake the Crust

• Bake at 400°F for 20 minutes, until golden and set.

Step 4: Add Toppings

• Spread sauce evenly over the crust.
• Add browned beef or sausage, remaining cheese, and your favorite pizza toppings.

Step 5: Final Bake

• Return to the oven and bake another 20 minutes at 400°F.

Step 6: Broil (Optional)

• Broil for 2–3 minutes to get that bubbly, golden top. Let rest for 3 minutes before slicing.

• Vegetarian? Skip the meat and add sautéed mushrooms, onions, and spinach.
