Step‑by‑Step Instructions for Zucchini Pizza Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C) to ensure it’s hot enough to create that perfect crust for your Zucchini Pizza Casserole. This temperature activates the ingredients effectively, giving you a delicious, golden finish. While the oven warms, gather your baking dish and prepare your ingredients for the next steps.
Step 2: Prepare the Zucchini
In a large bowl, combine the shredded zucchini with salt, tossing them gently. Allow this mixture to sit for about 10 minutes, enabling the salt to draw moisture from the zucchini. You’ll notice some liquid accumulating at the bottom of the bowl. This step is crucial for ensuring that your casserole doesn’t turn out soggy.
Step 3: Squeeze Out Moisture
After letting the zucchini sit, take a clean kitchen towel or cheesecloth and transfer the zucchini into it. With a firm grip, twist the fabric to squeeze out all excess moisture from the zucchini. This step helps achieve the non-soggy texture essential for your Zucchini Pizza Casserole crust, setting the foundation for a delightful dish.
Step 4: Make the Crust Mixture
In the same bowl, mix the drained zucchini with eggs, Parmesan cheese, and half of your mozzarella cheese. Stir everything together until you have a uniform mixture that will serve as the flavorful crust. The eggs and cheese will bind the zucchini nicely, giving you a tasty base ready for assembly.
Step 5: Shape the Crust
Grease a 9×13-inch baking dish with cooking spray or oil to prevent sticking. Transfer the crust mixture into this prepared dish and press it down evenly with your hands or a spatula. Aim for a consistent thickness across the bottom, as this will create a solid foundation for the toppings of the Zucchini Pizza Casserole.
Step 6: Bake the Crust
Place the baking dish in the preheated oven and bake the crust for about 20 minutes. You’ll want to look for a set and lightly browned crust that has a slight firmness when touched. This step is vital as it ensures that the base remains stable once all the toppings are added.
Step 7: Cook the Beef Mixture
While the crust is baking, heat a skillet over medium heat. Add the ground beef and chopped onion, cooking until the beef is browned and no longer pink—approximately 5-7 minutes. Be sure to drain any excess fat to keep your Zucchini Pizza Casserole light and flavorful. This mixture adds richness and depth to your casserole.
Step 8: Mix in the Vegetables
Once the beef is browned, stir in the pizza sauce, green bell pepper, sliced mushrooms, oregano, garlic powder, and black pepper. Allow this mixture to simmer for about 5 minutes over low heat, letting all the flavors meld together beautifully. Your kitchen will be filled with an irresistible aroma, hinting at the delightful layers to come.
Step 9: Assemble the Casserole
After the crust has baked, carefully spread the cooked beef mixture evenly over the zucchini crust, ensuring every bite will be deliciously packed with flavor. Smooth out the mixture with a spatula to cover the entire surface. This step is the heart of your Zucchini Pizza Casserole, bringing all the components together.
Step 10: Add the Cheese Toppings
Sprinkle the remaining mozzarella cheese and the entire amount of cheddar cheese over the beef layer. This cheesy topping will melt into gooey perfection as it bakes, creating a deliciously indulgent finish to your casserole. Make sure it’s evenly distributed for a glorious, cheesy bite in every slice.
Step 11: Bake Until Bubbly
Return the assembled Zucchini Pizza Casserole to the oven and bake for an additional 20 minutes. Keep an eye on it, looking for the cheese to melt and bubble gloriously. The top should become a lovely golden brown, signaling that it’s time for a delightful meal.
Step 12: Cool and Serve
After baking, remove the casserole from the oven and let it cool for a few minutes before slicing. This resting time allows the layers to set, making it easier to serve. Cut into squares and enjoy your delicious, healthy Zucchini Pizza Casserole, a satisfying dish that your family is sure to love!

You can store leftovers of your Zucchini Pizza Casserole in an airtight container in the refrigerator for up to 3-4 days. Be sure to cover it well to keep it from drying out.
