How this dish comes together

What you’ll need
To create your own Easy Low Carb Pizza Casserole, gather the following ingredients:
- 1 pound ground beef or turkey
- 1 cup bell peppers, diced (any color you prefer)
- 1 medium onion, chopped
- 2 cups marinara sauce (look for low-sugar options)
- 2 cups shredded mozzarella cheese
- 1 teaspoon Italian seasoning
- Salt and pepper to taste
- Optional: 1 cup sliced mushrooms or olives, for extra flavor
When selecting your ingredients, aim for high-quality marinara sauce for the best flavor. Feel free to swap in your favorite vegetables or add some spicy Italian sausage for an extra kick.
How to cook it
- Preheat your oven to 375°F (190°C). You’ll want a hot oven ready to crisp the top of the casserole.
- In a large skillet over medium heat, add your ground beef or turkey, cooking until it’s browned. This should take about 5-7 minutes. Break it apart with a wooden spoon, ensuring it cooks evenly.
- Once the meat is browned, add the onions and bell peppers into the pan. Stir them in and cook for another 3-4 minutes until the vegetables soften.
- Season with salt, pepper, and Italian seasoning. Pour in the marinara sauce, mixing well until everything is combined. Let it simmer for about 5 minutes.
- In a greased 9×13 inch baking dish, spread the meat and vegetable mixture evenly. Sprinkle 1 cup of mozzarella cheese over the top.
- Bake in the preheated oven for 20-25 minutes, until the cheese is melted and bubbly. For an extra crispy top, broil for 2-3 minutes, just until golden brown.

Serving suggestions
Once out of the oven, let your casserole rest for a few minutes; this allows the layers to settle and makes for easier serving. For plating, consider garnishing with fresh basil or a sprinkle of crushed red pepper flakes to elevate the presentation. This dish pairs wonderfully with a crisp green salad or some garlicky steamed broccoli, balancing the richness of the casserole with fresh, vibrant flavors.
Keeping leftovers fresh
Store any leftovers in an airtight container in the refrigerator for up to 5 days. If you’re planning to keep it for longer, freeze individual portions in freezer-safe bags—just make sure to label them with the date. To reheat, simply pop it in the microwave for 2-3 minutes or in a preheated oven at 350°F (175°C) until heated through.
Helpful cooking tips
- Don’t rush the browning of the meat; a nice crust will enhance the flavor.
- Experiment with cheese; a blend of mozzarella and provolone adds a lovely depth.
- For a spicier kick, add red pepper flakes to the meat while cooking.
- Consider using a cast-iron skillet for both cooking and serving; it retains heat incredibly well.
Creative variations
Feeling adventurous? Try swapping out the ground meat for shredded rotisserie chicken for a quicker option. You can also transform it into a vegetarian delight by using lentils or TVP in place of meat. For a seasonal twist, add pumpkin puree and sage during the fall, or load up with roasted zucchini in the summer.
Questions you might have
Can I make this ahead of time?
Absolutely! Assemble the casserole a day in advance, cover it tightly, and refrigerate until you’re ready to bake.What can I use instead of marinara sauce?
You can substitute with any low-carb tomato sauce or homemade tomato sauce; just adjust seasoning according to taste.Can I adjust the cooking times if I double the recipe?
Yes, if doubling, use a larger dish and check for doneness a few minutes earlier, as a larger volume may require additional cook time.
