My Personal Experience

Required Equipment
- Large Skillet: For browning the meat and sautéing the vegetables. A sturdy, non-stick skillet works best to avoid sticking.
- Cutting Board and Sharp Knife: Essential for chopping bell peppers and onions with ease. A quality knife makes prep work so much smoother.
- Mixing Bowls: For combining ingredients like cheese and seasonings. It helps to have bowls of different sizes.
- Casserole Dish: A medium-sized, oven-safe dish is perfect for layering the ingredients and achieving a beautiful bake.
- Grater: If you’re shredding your cheese fresh (highly recommended for better flavor and melting).
- Oven Mitts: Safety first—these will protect your hands when handling the hot casserole.
Ingredients & Substitutions
- 1 lb Ground Beef or Turkey: A hearty base that can be swapped with ground chicken or pork for a different flavor.
- 2 Bell Peppers (chopped): Use red, green, or yellow peppers depending on your preference.
- 1 Medium Onion (diced): Adds a subtle sweetness; can be replaced with shallots or omitted for a milder taste.
- 1 Cup Riced Cauliflower: Keeps the dish low-carb while adding texture. Sub with broccoli rice if desired.
- 1 Cup Tomato Sauce (sugar-free): Provides rich flavor. Ensure it’s keto-friendly by checking for no added sugars.
- 1 Cup Shredded Cheese: Cheddar, mozzarella, or a mix—choose your favorite!
- 1 tsp Garlic Powder: For depth of flavor. Fresh garlic can be used instead.
- 1 tsp Italian Seasoning: A blend of herbs that ties everything together. Customize with basil, oregano, or thyme.
- Salt and Pepper: To taste.
How to Make Keto Stuffed Pepper Casserole
Step 1: Prep the Ingredients
Chop the bell peppers and onion into small, even pieces. Rinse and drain the riced cauliflower if using store-bought. Preheat your oven to 375°F (190°C).
Step 2: Cook the Filling
In a large skillet over medium heat, brown the ground beef until fully cooked. Drain any excess grease. Add the diced onion, chopped bell peppers, and garlic powder. Sauté until the vegetables are tender.
Step 3: Add the Sauce
Stir in the tomato sauce, Italian seasoning, salt, and pepper. Mix well and let it simmer for 3–5 minutes to meld the flavors.
Step 4: Assemble the Casserole
Spread the cooked cauliflower rice evenly in the bottom of your casserole dish. Layer the meat mixture on top, ensuring even coverage. Sprinkle shredded cheese generously over the top.
Step 5: Bake to Perfection
Place the casserole dish in the preheated oven and bake for 15–20 minutes, or until the cheese is bubbly and golden.
Tips for This Recipe
