What Ingredients You Will Need

This cheesy low carb pizza casserole is made with simple ingredients you likely already have in your fridge or pantry. Here’s what you’ll need:

• Ground beef: Lean ground beef works best, but you can substitute ground turkey or chicken for a lighter option.
• Italian sausage: Adds a burst of flavor and spice. Sweet or mild sausage works great, too.
• Pizza sauce: Choose a low-carb or sugar-free option to keep it keto-friendly.
• Pepperoni slices: Use your favorite brand—turkey pepperoni is a great lower-fat alternative.
• Shredded mozzarella cheese: The star of the show! Go for whole milk mozzarella for the best melt and flavor.
• Parmesan cheese: Adds a salty kick to the cheesy topping.
• Vegetables: Bell peppers, mushrooms, and onions (optional, but they add a nice texture and flavor).
• Olive oil: For sautéing the veggies.
• Italian seasoning: A blend of oregano, basil, and thyme for that classic pizza taste.
• Salt and pepper: To season the meat and veggies perfectly.

Feel free to adjust the toppings based on your preferences or what you have in your fridge—this recipe is super forgiving!

Equipment Needed

You don’t need any fancy gadgets to make this cheesy low carb pizza casserole. Here’s what you’ll need:

• Large skillet: For browning the meat and cooking the veggies.
• Baking dish: A 9×13-inch dish works perfectly for layering and baking the casserole.
• Wooden spoon: For stirring the meat and sauce.
• Knife and cutting board: Essential for chopping veggies and prepping toppings.
• Cheese grater: Grate your own cheese for maximum flavor and melt.

If you don’t have a 9×13-inch baking dish, a deep-dish pie pan or smaller casserole dish will work just fine—though you may need to adjust your layering slightly.

Preparation Method

1. Preheat your oven: Start by preheating your oven to 375°F (190°C). This ensures even cooking and a bubbly, golden-brown top.
2. Cook the meat: Heat a large skillet over medium heat. Add 1 tablespoon of olive oil, followed by the ground beef and Italian sausage. Break the meat into small crumbles using a wooden spoon, and cook until browned, about 7-9 minutes. Season with salt and pepper.
3. Sauté the vegetables: If using veggies, add them to the skillet after the meat is cooked. Bell peppers, mushrooms, and onions work wonderfully. Sauté for 3-5 minutes until softened.
4. Add the pizza sauce: Stir in your low-carb pizza sauce and Italian seasoning. Let it simmer for 3-4 minutes so the flavors meld together.
5. Layer the casserole: In a greased 9×13-inch baking dish, spread half of the meat mixture as the base layer. Sprinkle a generous amount of mozzarella cheese on top, followed by half of your pepperoni slices. Repeat the layers with the remaining meat, cheese, and pepperoni.
6. Finish with cheese: Top the casserole with a mix of mozzarella and Parmesan cheese for that signature cheesy finish.
7. Bake: Place the casserole in the preheated oven. Bake uncovered for 20-25 minutes or until the cheese is melted and bubbling.
8. Cool and serve: Let the casserole rest for 5 minutes before serving. Slice into squares and enjoy!

Pro Tip: If your cheese isn’t golden brown on top, switch to broil for 1-2 minutes at the end of baking. Watch it closely to avoid burning!

Cooking Tips & Techniques

• Drain the meat: After cooking the ground beef and sausage, drain any excess grease to prevent a greasy casserole.
• Use freshly grated cheese: Pre-shredded cheese often has additives that prevent it from melting smoothly. Grating your own gives you better texture and flavor.
• Don’t skip resting: Allowing the casserole to cool for a few minutes makes it easier to serve and helps it hold together.
• Season generously: Don’t be shy with the salt, pepper, and Italian seasoning—these spices bring out the best in your dish.
• Make it crispy: For a crispy top layer, add a sprinkle of breadcrumbs or almond flour before baking.

Variations & Adaptations

• Vegetarian Version: Skip the meat and load up on veggies like zucchini, spinach, or eggplant. Add a layer of ricotta cheese for extra creaminess.
• Gluten-Free Option: This recipe is naturally gluten-free, but double-check your pizza sauce and toppings for hidden gluten.
• Chicken Pizza Casserole: Replace the ground beef and sausage with shredded rotisserie chicken for a lighter, protein-packed option.
• Spicy Twist: Add red pepper flakes or use spicy Italian sausage to kick up the heat.
• Breakfast Adaptation: Swap the pizza sauce for salsa, and use scrambled eggs instead of ground meat for a fun breakfast casserole idea.

One time, I added sliced black olives and artichokes to the layers, and it was a Mediterranean-inspired masterpiece. Don’t be afraid to get creative!

Serving & Storage Suggestions

This cheesy low carb pizza casserole tastes best when served hot and bubbly, straight from the oven. Pair it with a fresh green salad or roasted veggies for a complete meal. For drinks, sparkling water or even a glass of dry red wine complements the flavors beautifully.

Leftovers can be stored in the refrigerator for up to 4 days. Simply cover the baking dish with foil or transfer portions to airtight containers. To reheat, pop a slice in the microwave for 1-2 minutes or warm it in the oven at 350°F (175°C) until heated through.

If you’re meal prepping, this casserole freezes wonderfully. Wrap portions tightly in plastic wrap and store in freezer-safe containers for up to 3 months. Thaw overnight in the fridge before reheating. The flavors deepen over time, making leftovers even more delicious!
