Ingredients You’ll Need

These ingredients are simple, fresh, and work together perfectly to create the perfect balance of flavor, texture, and color. Each component plays a crucial role, from the tender, slightly roasted cauliflower to the bubbly, golden cheese on top.

• Cauliflower: A large head cut into small florets provides the healthy, hearty base for the casserole.
• Olive oil: Adds richness and helps the cauliflower roast to a perfect golden brown.
• Marinara sauce: The classic tomato flavor that brings all the authentic pizza vibes.
• Shredded mozzarella cheese: Melts beautifully, creating a gooey, cheesy layer that everyone loves.
• Salt, pepper, garlic powder, and Italian seasoning: Essential for seasoning the cauliflower and enhancing the overall flavor.
• Pepperoni or other toppings: The finishing touch to personalize your casserole and add a burst of savory flavor.

How to Make Cauliflower Pizza Casserole

Step 1: Prepare and Roast the Cauliflower

Start by preheating your oven to 425 degrees to ensure it’s nice and hot for roasting. Place the cauliflower florets in a 9×13 baking dish and toss them with olive oil, salt, pepper, and garlic powder to season evenly. Spread the cauliflower in a single layer so it roasts and caramelizes beautifully, then bake for 20 to 25 minutes until it starts to develop a light golden brown color. This roasting step brings out a lovely nutty flavor in the cauliflower that’s key to your Cauliflower Pizza Casserole.

Step 2: Add Marinara and Cheese Layers

Once your cauliflower is perfectly roasted, pull it out of the oven and spoon the marinara sauce evenly over the top. This tomato layer is the heart of the casserole’s pizza flavor. Next, sprinkle a generous amount of shredded mozzarella all over the sauce. Don’t forget to add a sprinkle of Italian seasoning to elevate all those rich, classic tastes.

Step 3: Top with Pepperoni and Bake Until Golden

Now for the fun part – add your pepperoni or other favorite pizza toppings over the cheese layer. Slide the casserole back into the oven and bake for an additional 12 to 15 minutes until the cheese is completely melted, bubbly, and golden in spots. This final bake melds all the flavors together and creates that mouthwatering pizza-style finish you’re craving.

Garnishes

Side Dishes

This hearty casserole pairs wonderfully with a crisp green salad dressed with lemon vinaigrette or a simple side of garlic bread. Both options provide a fresh contrast in texture and flavor, balancing the richness of the cheese and the savory depth of the pizza toppings.

Creative Ways to Present

For a fun twist, serve the Cauliflower Pizza Casserole in individual ramekins or mini cast iron skillets for an elegant, customizable presentation. Alternatively, you can scoop it into bowls and top with a sunny-side-up egg for an indulgent brunch option that everyone will love.

Make Ahead and Storage

Storing Leftovers

Freezing

This casserole freezes well if you want to prepare it in advance. Wrap it tightly in plastic wrap and aluminum foil or use a freezer-safe container. It will keep for up to 2 months. When ready, thaw overnight in the fridge before reheating.

Reheating
