Kitchen Equipment Needed

• Large skillet or non-stick pan
• 9×13 inch baking dish
• Mixing spoon or spatula
• Measuring cups and spoons
• Cheese grater (for best texture)
• Oven preheated to 375°F (190°C)

How To Make Low Carb Pizza Casserole

Start by browning the ground sausage in a skillet over medium heat. Break it apart with a spatula as it cooks. Once browned, drain any extra grease.

Add the chopped green peppers and onions. Sauté them for about 4–5 minutes until they begin to soften.

Next, stir in the garlic powder, oregano, basil, salt, and pepper. Pour in the marinara sauce and stir to combine everything well. Let this simmer for a few minutes.

Transfer the mixture to a greased 9×13 inch baking dish and spread it evenly. Sprinkle mozzarella and cheddar cheeses over the top. Layer on the pepperoni slices and sprinkle with mushrooms and olives if you like.

Top it all off with grated parmesan. Bake in the preheated oven for 20–25 minutes until the cheese is melted and bubbly with golden spots. Let it rest for 5–10 minutes before slicing and serving.

Customization Ideas for Easy Low Carb Pizza Casserole

This recipe is incredibly flexible. If you’re looking to go meatless, you can follow the lead of dishes like our Chickpea Beet Feta Salad and add hearty vegetables like spinach, zucchini, or roasted cauliflower.

For extra creaminess, consider adding dollops of ricotta or even a layer of cream cheese between the meat and cheese. If you want to go spicy, use hot Italian sausage and sprinkle crushed red pepper flakes before baking.

Add a Mediterranean twist using ideas from our Greek Chicken with Lemon and Feta by adding kalamata olives, sun-dried tomatoes, or feta.

Common Mistakes to Avoid When Making Pizza Casserole Recipe Keto

Here are a few key tips to ensure your pizza casserole recipe low carb turns out perfect every time:

• Don’t use high-carb marinara sauces. Always check labels for added sugars.
• Avoid skipping the sauté step. Raw veggies can release moisture and make the casserole watery.
• Drain your meat well before adding other ingredients.
• Keep an eye on bake time—overbaking can cause the cheese to become rubbery.
• Let the dish rest after baking so it sets nicely for slicing.

These mistakes are easily avoided, especially if you’re used to following low-carb recipes like our One Pot Creamy Sausage Gnocchi.

Serving and Presentation Tips for Pizza Casserole Recipe Low Carb

Cut into squares and serve warm with a side of crisp greens or a cucumber salad. Garnish with freshly chopped parsley or basil for a burst of freshness.

Serve it alongside low-carb sides like the Street Corn Creamy Cucumber Salad or the refreshing Cucumber Caesar Salad. For a fun presentation, use ramekins for individual portions.

How to Store and Reheat No Carb Pizza Casserole

This dish is perfect for meal prepping. Store leftovers in an airtight container in the refrigerator for up to four days. You can also freeze individual portions for up to two months.

Reheat in the microwave or in a preheated oven at 350°F until warmed through. To prevent the cheese from overcooking, cover loosely with foil if baking from frozen.
