- Simple Ingredients: You probably already have most of these ingredients in your pantry.
Ingredients for Zucchini Pizza Casserole
This recipe is simple yet flavorful. You’ll need:
- 2 medium zucchinis, sliced into rounds
- 1 lb ground beef or turkey
- 1 cup pizza sauce (look for a low-sugar version if possible)
- 1 ½ cups shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- 1 teaspoon Italian seasoning
- 1 teaspoon garlic powder
- ½ teaspoon onion powder
- 1 cup pepperoni slices (optional but highly recommended for authentic pizza taste)
- Fresh basil for garnish (optional)
Step-by-Step Zucchini Pizza Casserole Recipe
Step 1: Prepare the Zucchini
Preheat your oven to 375°F (190°C). Slice the zucchinis into rounds and lightly salt them. Let them sit for about 10-15 minutes to draw out excess moisture. Afterward, pat them dry with paper towels to prevent the casserole from becoming soggy.
Step 2: Cook the Ground Beef
In a large skillet, brown the ground beef over medium heat, breaking it apart as it cooks. Once the beef is fully cooked, drain any excess fat. Stir in the garlic powder, onion powder, and Italian seasoning to add flavor. Then, pour in the pizza sauce and let it simmer for a few minutes.
Step 3: Layer the Casserole
In a baking dish, spread a thin layer of the ground beef mixture on the bottom. Next, layer the zucchini slices evenly over the beef. Top the zucchini with the remaining beef mixture and finish with a generous layer of shredded mozzarella and Parmesan cheese.
Step 4: Add the Pepperoni
If you’re using pepperoni, arrange the slices evenly on top of the cheese. This step adds a deliciously crispy, savory element to the casserole, just like a traditional pizza.
Step 5: Bake the Casserole
Cover the baking dish with aluminum foil and bake for 20 minutes. After 20 minutes, remove the foil and continue baking for an additional 10 minutes or until the cheese is bubbly and golden brown.
Step 6: Garnish and Serve
Once out of the oven, sprinkle fresh basil over the casserole for a burst of color and freshness. Let the casserole sit for a few minutes before slicing and serving.
Tips for the Best Zucchini Pizza Casserole
- Use Fresh Zucchini: Fresh zucchini gives the best texture and flavor. If you use older zucchinis, they might be more watery.
- Don’t Skip the Salting: Salting the zucchini before baking helps draw out moisture, ensuring your casserole doesn’t become soggy.
- Customize the Toppings: You can add mushrooms, olives, or bell peppers for more flavor, just like a classic pizza.
- Make it Ahead: This casserole can be made ahead of time. Just assemble it and store it in the fridge for up to 24 hours. When ready, bake as instructed.
