Keto Sausage and Peppers Skillet

Ingredient Notes
(Detailed explanation of each ingredient and its purpose)
Italian Sausage
Italian sausage provides the main protein and flavor for this recipe. You can use:
- Sweet Italian sausage
- Spicy Italian sausage
- Chicken or turkey sausage
- Pork sausage
Sausage links can be sliced after browning or pre-sliced for convenience. Select a sugar-free sausage to keep the recipe strictly keto.
Olive Oil
Olive oil is used for sautéing the vegetables and browning the sausage. It adds richness and healthy fats. You may substitute avocado oil or butter if preferred.
Bell Peppers
Three different colors—red, yellow, and green—offer a beautiful mix of sweetness, bitterness, and crunch. Each pepper adds slight variations in flavor and visual appeal. Bell peppers are keto-friendly in moderate amounts and bring essential vitamins.
Onion
Onion adds sweetness and depth to the dish. While onions contain some carbohydrates, the amount used is controlled and balanced across servings, keeping the meal keto-compliant.
Garlic
Garlic adds flavor, aroma, and warmth. Fresh garlic is best, as it releases strong flavor when sautéed briefly. Avoid browning the garlic to prevent bitterness.
Diced Tomatoes
Canned diced tomatoes create a light, flavorful sauce without adding sugar. Choose a brand labeled “no sugar added” or “low carb.” Tomatoes enhance moisture and help the flavors meld.
Tomato Paste
Tomato paste enriches the sauce, thickening it while adding depth and concentrated tomato flavor. A small amount goes a long way.
Italian Seasoning
A blend of herbs such as basil, oregano, rosemary, and thyme gives the dish its classic Italian-inspired taste. It pairs perfectly with sausage and peppers.
Paprika
Paprika adds color and mild smokiness. You may use smoked paprika for deeper flavor.
Salt and Black Pepper
These simple seasonings enhance all the flavors and balance the natural sweetness of peppers.
Crushed Red Pepper Flakes
Optional, but adds heat and spice for those who prefer a spicy skillet dish.
Parsley
Fresh parsley brightens the dish visually and adds a fresh herbal note before serving.
