Step‑by‑Step Instructions for Keto Cheesy Sausage & Peppers

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This ensures a perfectly baked Keto Cheesy Sausage & Peppers casserole. While the oven heats up, gather all your ingredients, which will streamline your cooking process and make everything more enjoyable.

Step 2: Brown the Sausage
In a medium-high ovenproof skillet, add your Italian sausage. Cook it for about 6-8 minutes, breaking it apart with a spatula, until it’s fully browned and cooked through. Once browned, remove the sausage from the skillet and set it aside on a plate, allowing the flavors to develop further in the same pan.

Step 3: Sauté the Vegetables
Reduce the heat to medium and toss in the sliced red, green bell peppers, and onion into the skillet. Sauté for about 5-7 minutes, or until the vegetables are just tender and vibrant in color. This step adds layers of flavor to your casserole and creates a beautiful presentation, so stir occasionally for even cooking.

Step 4: Deglaze the Skillet
With the vegetables removed, drain any excess grease from the skillet. Then, deglaze the pan by pouring in about 1/2 cup of beef broth. Use a wooden spoon to scrape up any bits stuck to the bottom, which will enhance the flavor of your Keto Cheesy Sausage & Peppers sauce as it cooks.

Step 5: Prepare the Creamy Sauce
Whisk in 1 cup of heavy whipping cream along with a couple of tablespoons of tomato paste, Italian seasoning, salt, and pepper to taste. Cook this mixture for approximately 5 minutes until it thickens slightly. This creamy base is what makes the casserole indulgent and satisfying, so stir continuously to avoid burning.

Step 6: Melt the Cheese
Stir in the grated Parmesan cheese, allowing it to melt completely into the sauce, which should take an additional 2 minutes. The sauce should now be creamy and rich, perfectly enveloping the flavors of the Keto Cheesy Sausage & Peppers casserole.

Step 7: Combine Ingredients
Return the sausage and sautéed vegetables to the skillet, tossing them in the creamy sauce until everything is well-coated. This step harmonizes the ingredients, ensuring that every bite of your Keto Cheesy Sausage & Peppers is full of flavor and texture, ready for the oven!

Step 8: Bake the Casserole
Finally, sprinkle the top with a generous layer of shredded Mozzarella cheese. Place the skillet in the preheated oven and bake for 10-15 minutes, or until the cheese is bubbling and golden brown. This final touch creates a beautiful, gooey topping that pulls everything together for your delicious casserole.

How to Store and Freeze Keto Cheesy Sausage & Peppers

Fridge: Store leftovers in an airtight container in the refrigerator for up to 5 days. This helps maintain the creamy texture and prevents spoilage.

Freezer: For longer storage, freeze the casserole in a freezer-safe container for up to 3 months. Ensure it’s well-wrapped to prevent freezer burn.

Reheating: When ready to enjoy, thaw in the fridge overnight. Reheat in the oven at 350°F (175°C) until warmed through, adding extra cheese if desired for that gooey finish.

Make-Ahead Tip: Prep all ingredients ahead of time and assemble the casserole just before baking for an effortless weeknight dinner.
