Recipe

Zucchini Pizza Casserole transforms summer's abundant squash into a delightful, low-carb pizza alternative that satisfies comfort food cravings while incorporating nutritious vegetables. This creative dish captures all the beloved flavors of traditional pizza, using a zucchini-based crust that provides a hearty and flavorful foundation for classic toppings.

By carefully preparing the zucchini base and selecting complementary ingredients, home cooks can craft a versatile meal that appeals to both health-conscious eaters and pizza lovers alike. The casserole offers a simple yet innovative approach to enjoying pizza-inspired flavors without the heavy carbohydrate load of a traditional wheat crust.

Ingredients:

• 4 cups grated zucchini
• 2 large eggs
• 2 cups shredded mozzarella cheese
• 1 cup marinara sauce
• 1 cup pepperoni slices
• 1/2 teaspoon salt
• 1/4 teaspoon black pepper

Preheat the oven to 400°F and prepare a 9×13 inch baking dish with cooking spray. Grate the zucchini and place it in a clean kitchen towel, sprinkling with salt and allowing it to sit for 15 minutes to draw out excess moisture. Firmly squeeze the zucchini to remove as much liquid as possible, ensuring a firmer crust texture.

In a mixing bowl, combine the drained zucchini, beaten eggs, and 1 cup of mozzarella cheese. Press this mixture evenly into the prepared baking dish, creating a uniform base. Bake for 20 minutes until the crust sets and begins to turn golden around the edges.

Remove from the oven and top with marinara sauce, remaining cheese, and pepperoni slices, then return to the oven for an additional 10-15 minutes until the cheese melts and begins to brown.

For the best results, use fresh zucchini and take time to thoroughly drain the grated squash, which prevents a soggy crust. Consider experimenting with different toppings like vegetables, alternative meats, or even vegetarian options to personalize the casserole.

Leftovers can be stored in an airtight container and reheated, though the texture is most appealing when served fresh from the oven.

Cooking Steps

You'll start by thoroughly grating the zucchini, ensuring you remove every bit of excess moisture using a clean kitchen towel or cheesecloth to squeeze out liquid.

Next, mix your eggs and cheese into the zucchini, creating a uniform base that'll form the foundation of your pizza casserole.

Spread the mixture evenly in your baking dish, pressing it firmly to create a compact, golden-brown crust that'll serve as the perfect canvas for your favorite pizza toppings.

Step 1. Grate Zucchini Thoroughly

Grab your box grater and prepare to transform fresh zucchini into the perfect pizza casserole base. Position the grater vertically on a clean cutting board, selecting the largest-hole side for optimal texture. Firmly grip medium-sized zucchini and slide them down the grater's surface, creating long, uniform shreds that'll provide excellent moisture and volume.

Key grating tips:

• Use firm, consistent pressure
• Grate in one-directional strokes
• Rotate zucchini to maximize yield
• Stop grating when you reach the seeded core

Work quickly to prevent oxidation, which can darken the zucchini.

Aim for approximately 4 cups of loosely packed shreds, ensuring even cooking and a stable casserole foundation. Transfer grated zucchini to a clean kitchen towel, ready to squeeze out excess liquid for a crisp, sturdy base.

Step 2. Drain Zucchini Moisture Completely

After grating the zucchini, you'll need to tackle its notorious moisture problem head-on, ensuring a crisp and sturdy pizza casserole base.

Liberally salt the shredded zucchini and let it sit for 15 minutes, which draws out excess water through osmosis. Transfer the zucchini to a clean kitchen towel, then gather the edges and twist firmly, squeezing until no more liquid drips out.

You'll want to apply significant pressure, using your hands to compress the zucchini into a dense, dry mass.

Pro tips for maximum moisture removal:

• Use a fine-mesh strainer to pre-drain
• Press with consistent, firm pressure
• Check dryness by feeling the zucchini's texture
• Discard extracted liquid completely

Properly drained zucchini creates a perfect pizza casserole foundation.

Step 3. Mix Eggs, Cheese Thoroughly

Once your zucchini is expertly drained and moisture-free, combine the eggs and cheese to create the casserole's binding foundation.

Crack two large eggs into a mixing bowl, whisking them until uniformly beaten and slightly frothy. Gradually incorporate 1 cup of shredded mozzarella, stirring deliberately to ensure even distribution.

Key mixing techniques:

• Use a fork or whisk for smooth integration
• Fold ingredients gently to prevent deflating eggs
• Aim for a consistent, slightly sticky texture

Introduce the drained zucchini into the egg-cheese mixture, mixing thoroughly but carefully. The goal is a cohesive base that'll hold together when pressed into the baking dish.

Your mixture should look moist but not runny, with cheese and zucchini evenly suspended throughout the binding eggs.

Precision in mixing guarantees a sturdy, flavorful zucchini pizza casserole foundation.

Step 4. Spread Zucchini Mixture Evenly

Press the zucchini-egg-cheese mixture into your greased 9×13 inch baking dish, using a spatula or the back of a spoon to create an even, compact layer that resembles a rustic pizza crust.

You'll want to distribute the mixture carefully, ensuring no thin spots or uneven edges that might cook inconsistently.

Key spreading techniques include:

• Use gentle, even pressure
• Work from the center outward
• Smooth the surface with consistent strokes
• Aim for a uniform thickness of about 1/2 inch

Pay attention to the corners and edges, pressing firmly to create a solid foundation. Your goal is a smooth, compact base that'll support toppings without falling apart.

A perfectly spread mixture guarantees a delicious, structurally sound zucchini pizza casserole that'll impress everyone at the table.

Step 5. Bake Until Golden Brown

While the zucchini crust begins to set and transform, carefully monitor its golden-brown development during the initial 20-minute baking phase.

Watch for subtle color changes that indicate perfect doneness: a light golden hue signals the crust's readiness, with edges turning slightly crisp and firm.

Aim for an even golden color across the entire surface, which typically takes 18-22 minutes.

Key visual cues include:

• Edges pulling slightly away from baking dish
• Surface becoming matte instead of wet-looking
• Edges turning a deeper golden-brown shade

Your zucchini base should feel sturdy when touched, not soggy or liquid-like.

A well-baked crust provides the perfect foundation for your pizza toppings, ensuring a delightful texture that mimics traditional pizza crust without the extra carbohydrates.

Final Thoughts

Although zucchini pizza casserole might seem like a trendy culinary experiment, it's a genuinely delicious way to transform summer's most abundant vegetable into a crowd-pleasing meal.

You'll find this recipe offers incredible flexibility, letting you customize toppings and experiment with different cheese blends. The key is mastering moisture removal, which ensures a crisp, pizza-like base that won't become soggy.

Consider these final tips for success:

• Always drain zucchini thoroughly
• Use fresh, high-quality ingredients

• Serve immediately for optimal texture

Your zucchini pizza casserole can become a versatile, nutritious meal that impresses family and friends.
