How to Make Easy Low Carb Pizza Casserole Creating this Easy Low Carb Pizza Casserole is a straightforward process that brings all the flavors of pizza to your table without the carbs. Follow these simple steps, and you’ll have a delicious meal ready in no time! Step 1: Preheat the Oven Start by preheating your oven to 375°F. Preheating is crucial because it ensures even cooking. You want that cheese to melt perfectly and the casserole to bubble up just right! Step 2: Cook the Meat In a large skillet over medium heat, add your ground beef or Italian sausage. Cook until browned, breaking it apart with a spatula. This should take about 5-7 minutes. Once it’s cooked, drain the excess fat. This step is important to keep your casserole from becoming greasy. Step 3: Sauté the Vegetables Next, toss in the diced onion, bell pepper, and minced garlic. Sauté these for about 5 minutes until they’re softened and fragrant. The aroma will be irresistible! This step adds a depth of flavor that makes your casserole truly special. Step 4: Combine Ingredients Now, stir in the drained diced tomatoes, tomato sauce, oregano, basil, salt, and black pepper. Let this mixture simmer for about 5 minutes. Simmering allows the flavors to meld together beautifully, creating that classic pizza taste. Step 5: Layer the Casserole In a greased 9×13-inch baking dish, start layering. First, add half of the meat mixture, then half of the pepperoni, and half of the mozzarella cheese. Repeat these layers with the remaining ingredients. This layering technique ensures every bite is packed with flavor! Step 6: Bake the Casserole Place your casserole in the preheated oven and bake for 25-30 minutes. You’ll know it’s done when the cheese is bubbly and golden brown. Keep an eye on it; the smell will be hard to resist! Step 7: Cool and Serve Once it’s out of the oven, let the casserole cool for 5-10 minutes. This cooling time helps the layers set, making it easier to serve. If you like, garnish with fresh basil leaves for a pop of color and flavor! Tips for Success Use a non-stick spray or oil to grease your baking dish for easy cleanup. Don’t skip the simmering step; it enhances the flavors significantly. Feel free to customize with your favorite pizza toppings like mushrooms or olives. Let the casserole cool before cutting to maintain its shape. Store leftovers in an airtight container for up to three days. Equipment Needed Large skillet: Essential for browning the meat.

Variations Vegetarian Option: Swap the meat for a mix of sautéed mushrooms, zucchini, and spinach for a hearty veggie version. Spicy Kick: Add crushed red pepper flakes or jalapeños to the meat mixture for a fiery twist. Cheesy Delight: Mix in different cheeses like cheddar or pepper jack for a unique flavor profile. Low-Fat Version: Use lean ground turkey or chicken and reduced-fat cheese to cut down on calories. Gluten-Free: Ensure all sauces and toppings are certified gluten-free for a safe option. Serving Suggestions Pair with a crisp green salad drizzled with balsamic vinaigrette for a refreshing contrast. Serve with garlic bread or low-carb breadsticks for a satisfying side.
