Ingredients You’ll Need

One of the best things about Zucchini Pizza Casserole is its simplicity—every ingredient works hard to deliver on flavor, texture, and that essential pizza vibe. Here’s what makes this recipe shine (and why you won’t want to skip a single thing!).

• Zucchini: The fresh, shredded zucchini forms our light, savory “crust;” it’s mild and soaks up all the garlicky, cheesy goodness.
• Eggs: These are the magic binders, holding the zucchini base together for a sturdy, sliceable casserole.
• Mozzarella Cheese: Both creamy and gooey, mozzarella is used in the crust and as a topping for that classic, stretchy cheese pull.
• Cheddar Cheese: Adds a touch of sharp flavor and gorgeous orange color to the zucchini base.
• Parmesan Cheese: Brings a salty, nutty punch and makes the crust beautifully golden when baked.
• Pizza Sauce: Zesty and tangy, this gives you the unmistakable “pizza” experience in every bite.
• Pepperoni Slices: A layer of savory, crowd-pleasing flavor; keep or swap as you like!
• Fresh Basil: Brings freshness, color, and that irresistible Italian aroma—don’t skip the garnish!
• Salt & Black Pepper: Simple seasoning is all you need to spotlight the zucchini and cheeses.
• Optional Toppings: Sausage, black olives, bell peppers, onions, mushrooms, bacon, or a dash of red pepper flakes—the sky’s the limit!

Variations

Zucchini Pizza Casserole is endlessly adaptable! You can tailor it to suit special diets, what’s in your fridge, or everyone’s pizza cravings—no rules, just delicious possibilities.

• Make It Vegetarian: Skip the pepperoni or sausage and load up with extra veggies like bell peppers, mushrooms, and spinach for a garden-fresh twist.
• Keto-Friendly: Use a sugar-free pizza sauce and double check your toppings to keep things extra low-carb.
• Spicy Supreme: Add hot Italian sausage, fresh jalapeños, or a shower of red pepper flakes for that fiery kick.
• Dairy-Free: Try your favorite plant-based cheese alternatives; just ensure they melt well, so you still get that irresistible cheesy topping.

How to Make Zucchini Pizza Casserole

Step 1: Prep and Grate the Zucchini

Start by preheating your oven to 400°F and greasing a 9×13-inch glass baking dish. Then, grab your zucchini—no need to peel! Grate them on the large holes of your box grater until you have about 4 cups. The fresher and firmer the zucchini, the better your crust turns out.

Step 2: Salt and Drain

Spread your grated zucchini in a large bowl or colander, sprinkle with salt, and let it stand for 10 minutes. This draws out moisture—crucial for a crust that isn’t watery! After 10 minutes, wrap the zucchini in a clean tea towel and wring it out hard over the sink. Squeeze until no more water drips out.

Step 3: Make the “Crust”

Tip the well-drained zucchini into a large bowl. Add the eggs, black pepper, 1 cup of mozzarella, 1 cup of cheddar, and the grated parmesan. Stir until everything is combined and you see beautiful flecks of cheese and zucchini evenly mixed throughout.

Step 4: Bake the Zucchini Base

Scrape the cheesy zucchini mixture into your prepared dish, pressing it gently into an even layer. Slide it into the oven and bake for 20 minutes—your kitchen will already start to smell like pizza heaven.

Step 5: Add Pizza Toppings and Bake Again

Carefully remove the dish from the oven. Spread the pizza sauce evenly over the baked zucchini base, then sprinkle with the remaining mozzarella. Layer on pepperoni and any extra toppings you love—like chopped onions, peppers, or mushrooms. Return to the oven and bake for another 15 minutes, until the cheese bubbles and browns in spots.

Step 6: Garnish and Serve

Once the cheese is golden and irresistible, pull your casserole from the oven. Shower with fresh basil for an instant pop of color and flavor. Let it cool five minutes to set up a bit, then slice and savor—you’ve just made Zucchini Pizza Casserole magic!

How to Serve Zucchini Pizza Casserole

Garnishes

A handful of fresh basil ribbons (chiffonade) brightens every piece, and a swipe of extra parmesan or a sprinkle of red pepper flakes adds irresistible finishing flair. If you’re feeling fancy, a drizzle of olive oil just before serving brings an extra Italian touch.

Side Dishes

This casserole is hearty enough to stand alone, but it’s also right at home with a crisp green salad, some garlic bread, or even a bowl of minestrone—think classic pizzeria vibes, but right at your own table!

Creative Ways to Present

Slice into squares and serve as a main dish, or cut smaller pieces for a party-ready appetizer tray. Individual ramekins make for an extra cute (and mess-free!) lunchbox option, and leftovers reheat beautifully for next-day pizza cravings.

Make Ahead and Storage

Storing Leftovers

Allow any leftover Zucchini Pizza Casserole to cool completely, then store slices in an airtight container in the refrigerator. It’ll stay fresh and fabulous for up to 4 days—making it perfect for grab-and-go lunches or a quick weeknight repeat.

Freezing

For longer storage, this casserole freezes surprisingly well. Wrap cooled slices tightly in foil, then place them in a freezer-safe bag or container. They’ll keep for up to three months—just thaw overnight in the fridge before reheating.

Reheating

To recapture that just-baked magic, warm individual pieces in a 350°F oven for about 10–12 minutes or microwave for 1–2 minutes (the oven gives a better texture). The cheese will melt and bubble all over again—just like new!
