• 1 cup sliced pepperoni: Adds richness, smokiness, and a hint of spice. It crisps up beautifully in the oven.
• 2 cups sliced red and green bell peppers: A colorful medley that brings sweetness, crunch, and nutrition.
• 2 cups shredded mozzarella cheese: The essential melty layer that brings it all together. Creamy and stretchy!
• ½ cup grated Parmesan cheese: Adds salty, nutty depth and helps create a golden crust on top.
• 1 tsp Italian seasoning: A balanced blend of herbs like basil, oregano, and thyme for classic Italian flavor.
• ½ tsp garlic powder: Infuses the dish with warm, garlicky undertones without overwhelming it.
• Salt & black pepper to taste: Simple seasonings to enhance and balance all the savory components.
• Olive oil (as needed): Used for greasing the pans and helping ingredients sauté without sticking.

Customization Tip: Swap Italian seasoning for a blend of oregano and thyme, or add a pinch of red pepper flakes for extra heat!

How to Make Low-Carb Sausage & Pepperoni Casserole

Step 1: Preheat and Prep

Preheat your oven to 375°F (190°C). Lightly grease two individual-sized foil pans or one medium baking dish with olive oil to prevent sticking.

Step 2: Cook the Ingredients

• In a skillet over medium heat, brown the sliced Italian sausage until fully cooked and slightly crisped. Remove and set aside.
• In the same pan, sauté the sliced bell peppers for about 5 minutes until slightly softened but still vibrant.

Step 3: Mix and Assemble

In a large mixing bowl, combine the cooked sausage, sautéed peppers, sliced pepperoni, Italian seasoning, garlic powder, and a pinch of salt and pepper.

• Divide the mixture evenly between your prepared pans.
• Top generously with shredded mozzarella and Parmesan cheese.

Step 4: Bake to Perfection

Place the pans on a baking sheet and transfer to the oven. Bake uncovered for 20–25 minutes, or until the cheese is melted, bubbly, and golden brown around the edges.

Step 5: Cool and Serve

Remove from the oven and let cool for 5–10 minutes. This helps everything set and makes serving easier. Plate up and enjoy the gooey, cheesy, meaty goodness!
