How to Make Low Carb Pizza Casserole Recipe

Step 1: Steam the Cauliflower

Begin by placing the bite-size cauliflower florets into a microwave-safe bowl filled with 1 cup of water. Cover this bowl with a damp paper towel and microwave on high for about 3 minutes. The goal is to get the cauliflower tender but not soggy, so keep a close eye—overcooking will lose the perfect texture.

Step 2: Drain and Dry

Once steamed, drain the cauliflower carefully and pat it dry with a paper towel. Getting rid of excess moisture is key to avoid a watery casserole later.

Step 3: Preheat Your Oven

Set your oven to 400 degrees Fahrenheit so it’s fully ready for baking once your casserole is assembled.

Step 4: Cook the Italian Sausage

In a large skillet over medium-high heat, cook the Italian sausage thoroughly—about 15 minutes—breaking it up as it cooks. After it’s done, drain any excess fat to keep the dish from becoming greasy but retain all that meaty flavor.

Step 5: Sauté the Mushrooms

Using the same skillet, add olive oil and sauté sliced mushrooms for 10 minutes to remove their moisture. This step intensifies the mushroom flavor and prevents the casserole from becoming soggy.

Step 6: Prepare the Casserole Dish

Spray a 13×9 inch casserole dish with non-stick spray. Spread half a cup of the low carb pasta sauce evenly on the bottom. This acts as the flavorful base layer that keeps every bite saucy and delicious.

Step 7: Combine the Vegetables and Meat

In a large bowl, toss together the steamed cauliflower, cooked sausage, sautéed mushrooms, and chopped green peppers until everything is well mixed. Each bite will have a perfect balance of flavors.

Step 8: Layer the First Half

Spread half of the vegetable and meat mixture evenly in the casserole dish. Then spoon on half a cup of pasta sauce, followed by half of the pepperoni slices—pressing them slightly into the layers—and top with 6 ounces of shredded mozzarella cheese.

Step 9: Build the Second Layer

Spread the remaining half of the mixture over the cheese layer. Add the rest of the pepperoni slices (save about 10 slices for topping), pour on the remaining half-cup of pasta sauce, and sprinkle with the final 6 ounces of mozzarella cheese.

Step 10: Prepare the Parmesan Topping

Mix the powdered Parmesan cheese and Italian seasoning in a small bowl until well combined. This mix will add a sharp, herby crust to your casserole’s surface.

Step 11: Add the Final Touches

Evenly sprinkle the Parmesan and Italian seasoning mixture over the top of the casserole. Then arrange the last 10 pepperoni slices on top for a visually appealing and flavor-packed finish.

Step 12: Bake Until Perfect

Place the casserole in the oven and bake for 30 minutes. You’ll know it’s ready when the casserole is hot throughout and the cheese is beautifully melted and bubbly.

How to Serve Low Carb Pizza Casserole Recipe

Garnishes

Sprinkle some fresh chopped basil or parsley on top just before serving to add a pop of color and fresh herbal aroma. A light drizzle of extra virgin olive oil can also elevate the flavors beautifully.

Side Dishes

This casserole shines as a standalone meal, but if you want to add some greens, consider a crisp Caesar salad or a simple mixed greens salad with a tangy vinaigrette to balance out the richness.

Creative Ways to Present

Serve individual portions in small ramekins for a chic presentation at dinner parties. You can also pair it with keto-friendly garlic bread or roasted vegetables for a complete low carb feast.

Make Ahead and Storage

Storing Leftovers

Store any leftover Low Carb Pizza Casserole Recipe in an airtight container in the refrigerator for up to 4 days. The flavors actually develop even more after sitting, making the next day almost as good as the first.

Freezing

Reheating

Reheat leftovers in the oven at 350 degrees Fahrenheit for about 15-20 minutes until warmed through. Using the oven keeps the cheese melty and preserves the texture better than a microwave.
