Zucchini Pizza Casserole Ingredients

For the Zucchini Crust

  • Shredded Zucchini – Essential for creating the crust while keeping carbs low; remember to squeeze out excess moisture.
  • Salt – Helps to enhance the flavor and draws moisture from the zucchini for a firmer crust.

Step‑by‑Step Instructions for Zucchini Pizza Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This ensures a properly hot environment to bake your Zucchini Pizza Casserole, aiming for a crispy crust. While the oven is heating, gather all your ingredients together on the counter to streamline your cooking process.

Step 2: Prepare the Zucchini
In a large mixing bowl, combine the shredded zucchini with salt. Let this mixture sit for 10 minutes; during this time, the salt will draw out excess moisture from the zucchini, aiding in a firm crust. This crucial step helps prevent a soggy base later on.

Step 3: Drain Excess Moisture
After 10 minutes, grab a clean kitchen towel or cheesecloth and carefully squeeze the zucchini to remove as much moisture as possible. This step is vital for achieving a firm, golden crust in your Zucchini Pizza Casserole, so be thorough!

Step 4: Mix the Crust Ingredients
In the same bowl, mix the drained zucchini with eggs, grated Parmesan cheese, and half of the shredded mozzarella. Use a spatula to combine these ingredients until you achieve a uniform mixture. This mixture will serve as the base for your casserole, giving it structure and a cheesy flavor.

Step 5: Form the Crust
Grease a 9×13-inch baking dish with cooking spray or olive oil to prevent sticking. Transfer the zucchini mixture into the dish and press it evenly into the bottom, forming an even crust. Make sure the layer is compacted well to ensure it holds together during baking.

Step 6: Bake the Crust
Pop the baking dish into your preheated oven and bake the crust for 20 minutes. Keep an eye on it; the edges should start turning lightly golden, and the center should be set. This step locks in the flavors and creates a solid base for your Zucchini Pizza Casserole.

Step 7: Cook the Beef Filling
While the crust bakes, heat a skillet over medium heat. Add ground beef and chopped onion, cooking until the meat is browned and no longer pink, about 5-7 minutes. Once cooked, drain any excess fat, ensuring your filling isn’t greasy.

Step 8: Add Toppings to Beef
Stir in pizza sauce, diced green bell pepper, sliced mushrooms, dried oregano, garlic powder, and black pepper into the browned beef. Let this mixture cook for another 5 minutes, allowing the flavors to meld together and the veggies to soften slightly.

Step 9: Assemble the Casserole
Once the zucchini crust has baked and set, spread the beef and vegetable mixture evenly on top of the crust. This creates a hearty layer full of flavor in your Zucchini Pizza Casserole. Use a spatula to ensure even coverage for each bite.

Step 10: Add Cheese Topping
Sprinkle the remaining mozzarella and all of the cheddar cheese generously over the beef mixture. This cheese layer will melt and bubble delightfully during the second bake, creating that gooey pizza experience everyone loves.

Step 11: Bake Again
Return the casserole to the oven for an additional 20 minutes. Keep an eye on it; the cheese should be melted and bubbly, with a golden brown hue on top. This final bake brings everything together in a deliciously comforting way.

Step 12: Cool and Serve
Once baked, remove the Zucchini Pizza Casserole from the oven and let it cool for a few minutes. This cooling period allows the layers to set slightly, making it easier to slice. Serve warm and enjoy every cheesy bite!

  • Extra Crunch: For a delightful texture contrast, top your casserole with crushed pork rinds or breadcrumbs (gluten-free if needed) before the final bake. This gives an appealing crunch that everyone will love.
