Step‑by‑Step Instructions for Zucchini Pizza Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This crucial step ensures that the zucchini pizza casserole gets that beautifully set crust right from the start, allowing it to firm up and achieve a delightful golden-brown hue.
Step 2: Prepare the Zucchini
Next, take your shredded zucchini and toss it with a sprinkle of salt. Let this mixture sit for about 10 minutes to draw out excess moisture. This step is vital to prevent your casserole from becoming soggy, so keep an eye on the zucchini as it releases liquid.
Step 3: Drain the Zucchini
Once the zucchini has released its moisture, grab a clean kitchen towel and place the zucchini in the center. Squeeze it tightly to remove as much liquid as possible. You want the zucchini to feel quite dry to help create a sturdy base for your casserole.
Step 4: Mix the Crust Ingredients
In a large mixing bowl, combine the drained zucchini with beaten eggs, grated Parmesan cheese, and half of the shredded mozzarella. Stir well until everything is evenly incorporated and forms a cohesive mixture. This will be the flavorful crust of your Zucchini Pizza Casserole.
Step 5: Press the Crust Mixture
Grease a 9×13-inch baking dish with a bit of olive oil or non-stick spray. Evenly press the zucchini mixture into the base of the dish to form a solid crust. Aim for an even layer, creating a platform for the mouthwatering toppings to follow.
Step 6: Bake the Crust
Place the baking dish in the preheated oven and bake for about 20 minutes. The crust should become set and develop a light golden color. Keep an eye on it; you want it firm enough to hold all the tasty toppings to come.
Step 7: Cook the Beef Mixture
While the crust bakes, heat a skillet over medium heat and brown the ground beef along with the chopped onions. This should take around 5-7 minutes until the beef is thoroughly cooked. Drain any excess fat, then stir in the pizza sauce, bell pepper, mushrooms, dried oregano, garlic powder, and black pepper. Let everything simmer for about 5 minutes to meld the flavors.
Step 8: Assemble the Casserole
After the crust is baked, take it out of the oven and evenly spread the beef mixture over the base. Make sure to cover every inch of the crust so that every bite of the Zucchini Pizza Casserole is packed with flavor and satisfaction.
Step 9: Add Toppings
Next, sprinkle the remaining mozzarella cheese and all of the cheddar cheese evenly over the beef mixture. This cheesy layer is essential for that satisfying, melty finish that will make this casserole truly irresistible.
Step 10: Bake Again
Return the assembled casserole to the oven and bake for an additional 20 minutes. Look for the cheese to melt and become bubbly, with a lovely golden-brown color starting to form on top, indicating that it’s ready to come out.
Step 11: Cool and Serve
Once out of the oven, allow the Zucchini Pizza Casserole to cool for a few minutes before slicing. This step is crucial for cleaner pieces, letting the flavors settle and meld together perfectly for each delicious serving.

Zucchini Pizza Casserole Recipe FAQs
How can I choose the best zucchini for my casserole?
Absolutely! Look for firm, glossy zucchinis without dark spots or blemishes. Small to medium-sized zucchinis are ideal since they have fewer seeds and are sweeter. If you notice any that are overly large or have firm, woody cores, it’s best to avoid them.
What is the best way to store leftover zucchini pizza casserole?
Very good question! Store any leftovers in an airtight container in the fridge for up to 3 days. Make sure it’s completely cooled before sealing to keep it fresh. I often use glass containers, as they help keep the flavors intact.
Can I freeze zucchini pizza casserole? If so, how?
Yes, you can! To freeze your casserole, allow it to cool completely. Wrap it tightly in plastic wrap or aluminum foil, then place it in a freezer-safe container. It will keep well for up to 3 months. To reheat, thaw overnight in the fridge and bake it in the oven at 350°F (175°C) for about 15-20 minutes or until warmed through.
What do I do if the zucchini crust is too soggy?
Absolutely! If you find that your zucchini crust is too soggy, it’s crucial to drain the shredded zucchini well after salting it. Squeeze it vigorously in a clean kitchen towel until no more moisture seeps out. You can also bake your crust a bit longer at a lower temperature to firm it up before adding the toppings.
Are there any dietary considerations I should be aware of with this casserole?
Definitely! This Zucchini Pizza Casserole is gluten-free thanks to the absence of traditional pizza dough. However, if you are cooking for pets or someone with allergies, be cautious with cheese and ensure any substitutions are safe.
