Zucchini Pizza Casserole Ingredients
For the Crust
• Shredded Zucchini – Forms the base of the crust, providing moisture and a light sweetness. Note: Make sure to salt and drain to prevent sogginess.
• Salt – Allows zucchini to release moisture for a firmer crust. It’s essential for textural integrity.
• Eggs – Binding agent that holds the crust together, adding richness. No substitutions necessary for its role.
• Grated Parmesan Cheese – Adds depth and structure to the crust. Can substitute with pecorino or nutritional yeast for a vegan option.
For the Toppings
• Shredded Mozzarella Cheese – Provides gooeyness and stretch when melted, split between crust and topping for flavor infusion. Low-moisture mozzarella is preferred.
• Shredded Cheddar Cheese – Offers sharpness and color on top. Can be replaced with gouda or another melting cheese if preferred.
• Ground Beef – Adds hearty flavor and makes the dish protein-rich. Can substitute with turkey, chicken, or plant-based proteins.
• Chopped Onion – Sweetens when cooked, forming a flavorful base for the filling. Use shallots for a milder taste.
• Pizza Sauce – Ties all elements together with acidity and flavor. Homemade or store-bought sauces both work well.
• Green Bell Pepper – Introduces crunch and mild sweetness. Feel free to use red or yellow peppers for a sweeter note.
• Sliced Mushrooms – Contribute an earthy taste and absorb sauce, enriching each bite. Other options include spinach or zucchini for added greens.
Seasonings
• Dried Oregano – Classic pizza seasoning that adds warmth to the filling. Basil can be used for a different flavor profile.
• Garlic Powder – Infuses savory depth into the filling. Fresh garlic can be substituted, but adjust the quantity accordingly.
• Black Pepper – Adds mild heat, rounding out the flavor. Adjust to taste.
Step‑by‑Step Instructions for Zucchini Pizza Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This essential first step ensures that your Zucchini Pizza Casserole bakes evenly and reaches that perfect golden-brown finish. While the oven heats, gather your tools: a baking dish, mixing bowl, and a clean towel for squeezing moisture from the zucchini.
Step 2: Prepare the Zucchini
In a spacious mixing bowl, toss the shredded zucchini with a pinch of salt. Allow it to sit for 10 minutes; this process helps the zucchini release excess moisture. You’ll notice the zucchini starting to glisten as it softens. This step is critical for achieving a firm crust in your casserole.
Step 3: Drain Excess Moisture
After letting the zucchini sit, take a clean towel or cheesecloth and squeeze out as much liquid as possible. The goal is to achieve a dry texture to prevent your Zucchini Pizza Casserole from becoming soggy. You’ll be left with a drier, more concentrated zucchini base, ready to form the crust.
Step 4: Mix the Crust Ingredients
In the same mixing bowl, combine the drained zucchini with beaten eggs, grated Parmesan cheese, and half of the shredded mozzarella. Stir until everything is well mixed, ensuring a uniform texture. The egg acts as a binder, so make sure no clumps remain to ensure your crust holds together beautifully when baked.
Step 5: Form the Crust
Grease a 9×13-inch baking dish with non-stick spray or olive oil. Evenly press the zucchini mixture into the bottom of the prepared dish, creating a compact, even layer. It should look slightly smooth on top—this will form the sturdy base for your Zucchini Pizza Casserole to shine once baked.
Step 6: Bake the Crust
Place the dish in the preheated oven and bake for 20 minutes. You’ll want to keep an eye on it until it is just set and lightly browned on top. This pre-baking step is crucial for achieving that firm foundation that will hold your delicious toppings.
Step 7: Cook the Ground Beef
While your crust bakes, heat a skillet over medium heat. Add the ground beef along with the chopped onion, cooking until the meat is browned and the onions are translucent. Stir occasionally to ensure even cooking. Once ready, drain any excess fat to keep your Zucchini Pizza Casserole from becoming greasy.
Step 8: Add Vegetables and Seasoning
Mix in the pizza sauce, bell pepper, sliced mushrooms, dried oregano, garlic powder, and black pepper into the beef and onion mix. Allow everything to simmer for 5 minutes on low heat, enabling the flavors to meld beautifully. This savory filling will complement your zucchini crust perfectly.
Step 9: Assemble the Casserole
Once the zucchini crust is baked, remove it from the oven and spread the beef and vegetable mixture evenly over the top. Be sure to reach every corner, ensuring that each bite packed with hearty goodness. This layering enhances the flavors, making your Zucchini Pizza Casserole irresistible.
Step 10: Add the Cheese Toppings
Sprinkle the remaining mozzarella cheese and all the shredded cheddar cheese on top of the beef mixture. The cheese will melt and create that gooey, comforting layer we all associate with delicious pizza. Make sure to spread it evenly so each bite is cheesy and delicious.
Step 11: Bake Again
Return the assembled casserole to the oven and bake for an additional 20 minutes. You’ll know it’s done when the cheese is melted and bubbling, creating a tempting golden crust. The lovely aroma will fill your kitchen, promising a delectable meal ahead.
Step 12: Cool and Serve
After baking, allow your Zucchini Pizza Casserole to cool for a few minutes before slicing. This will help the layers set slightly, making it easier to serve. Once ready, dish it out and enjoy a wonderful twist on pizza that will surely become a family favorite!

Zucchini Pizza Casserole Recipe FAQs
How do I choose the right zucchini for this recipe?
Absolutely! Look for firm, shiny zucchinis with smooth skin. Avoid any that have dark spots or soft areas—these may indicate overripeness. Medium-sized zucchinis are ideal, as they have a good balance of moisture and flavor.
How should I store leftovers of the Zucchini Pizza Casserole?
Very good question! Once your casserole has cooled completely, transfer it to an airtight container and refrigerate. It will stay fresh for up to 3-4 days. Just make sure to keep it well-sealed to retain that scrumptious flavor.
Can I freeze Zucchini Pizza Casserole?
Absolutely! If you plan to freeze leftovers, wrap the casserole tightly in plastic wrap followed by aluminum foil or place it in a freezer-safe container. It can be frozen for up to 3 months. To reheat, simply thaw overnight in the fridge and rewarm in the oven at 350°F (175°C) for about 20 minutes, or microwave individual portions.
What should I do if my zucchini crust is soggy?
If you find your zucchini crust is soggy, it’s likely due to not squeezing out enough moisture. Next time, try salting the shredded zucchini and letting it sit before draining it thoroughly with a towel. You can also pre-bake it longer to ensure it’s fully set before adding the toppings.
Are there any dietary considerations for pets or allergies?
It’s important to keep pets away from this dish, especially due to the cheese and spices. For allergies, be cautious with common allergens like dairy or gluten. You can easily make the casserole gluten-free by using alternative sauces and ensuring that your cheese is gluten-free certified.
How can I customize the toppings to suit my family’s tastes?
The more the merrier! Feel free to add your family’s favorite pizza toppings—think olives, pepperoni, or additional veggies like spinach and artichokes. For vegetarian options, swap the ground beef for lentils or chickpeas for a delicious twist while keeping the dish nutritious and low-carb.
