4 cups shredded unpeeled zucchini – make sure to shred it finely for the best texture in your crust.
1/2 teaspoon salt – helps draw out moisture from the zucchini.
2 large eggs – these act as the binder for our zucchini crust.
1/2 cup grated Parmesan cheese – adds a salty, nutty flavor and helps crisp up the base.
1 cup shredded part-skim mozzarella cheese, divided – essential for that gooey, cheesy goodness, divided for the crust and topping.
1 cup shredded cheddar cheese, divided – for an extra layer of savory flavor, also divided.
1 pound ground beef – a hearty base for our pizza topping.
1/2 cup chopped onion – adds aromatic depth to the meat sauce.
1 can (15 ounces) Italian tomato sauce – the perfect pizza sauce base.
1 medium green or red pepper, chopped – for a little freshness and color in the topping.

How to Make Zucchini Pizza Casserole

Ready to create this amazing quick zucchini pizza casserole? It’s easier than you think! Follow these steps to get that perfect pizza flavor without the crust.

Step 1: Preheat your oven to 400°F (200°C). Lightly grease a 9×13-inch baking dish. This ensures nothing sticks and makes cleanup a breeze.
Step 2: Prepare the zucchini crust. In a large bowl, combine the 4 cups shredded unpeeled zucchini (make sure it’s well-drained to avoid a soggy bottom!) with the 2 large eggs, 1/2 cup grated Parmesan cheese, and half of both the 1 cup shredded part-skim mozzarella cheese and 1 cup shredded cheddar cheese. Mix everything together until it’s well combined.
Step 3: Form the base. Spread the zucchini mixture evenly into the prepared baking dish. Press it down firmly with your hands or a spatula to create a solid base. Bake this for 20 minutes, or until the surface looks set and is just starting to turn lightly golden. The aroma will start to fill your kitchen!
Step 4: Cook the meat sauce while the base bakes. In a skillet over medium heat, brown the 1 pound ground beef. Once cooked through, add the 1/2 cup chopped onion and cook until it becomes soft and translucent. Drain off any excess grease.
Step 5: Add the sauce and veggies. Stir in the 1 can (15 ounces) Italian tomato sauce and the 1 medium green or red pepper, chopped. Let this simmer gently for about 5–7 minutes, allowing the flavors to meld together beautifully. It should smell wonderfully pizza-like!
Step 6: Assemble your masterpiece. Carefully remove the pre-baked zucchini crust from the oven. Evenly spread the savory meat sauce mixture over the top, making sure to cover the entire surface.
Step 7: Top it off and bake again. Sprinkle the remaining mozzarella and cheddar cheeses evenly over the meat sauce. Return the dish to the oven and bake for an additional 20 minutes. You’re looking for that bubbly, golden-brown cheese on top – pure deliciousness! This completes the how to make zucchini pizza casserole process.
Step 8: Let it rest. Once out of the oven, let the casserole sit for about 5–10 minutes before slicing. This short resting period helps everything set, making it easier to serve perfect slices.

Pro Tips for the Best Zucchini Pizza Casserole

Want to elevate your zucchini pizza creation? Here are a few tricks I’ve picked up that make all the difference:

Always drain your shredded zucchini really well. Squeeze out as much liquid as possible using cheesecloth or a clean kitchen towel – this is key to avoiding a watery casserole.
Don’t skip pre-baking the zucchini crust! This step is crucial for getting a firm, pizza-like base that holds up to the toppings.
Feel free to mix up the cheeses. While mozzarella and cheddar are classic, a little provolone or Monterey Jack can add even more depth.
For an even richer flavor, consider adding a pinch of dried oregano or basil directly into the zucchini crust mixture.

The real secret is thoroughly draining the zucchini and pre-baking the crust. This ensures you get that wonderfully firm, slightly golden base that supports all the delicious, cheesy toppings without getting soggy.

Yes, you absolutely can! You can prepare the zucchini crust mixture and the meat sauce separately up to 24 hours in advance and store them in the refrigerator. Assemble and bake just before serving.
