Ingredients
This recipe makes 4 generous servings.
For the Sausage and Peppers
- 1 tablespoon olive oil
- 1.5 pounds Italian sausage (sweet or hot, casings removed if preferred, or cut into 1-inch pieces)
- 1 large red bell pepper, seeds removed and sliced into strips
- 1 large green bell pepper, seeds removed and sliced into strips
- 1 medium yellow onion, sliced
- 3 cloves garlic, minced
For the Sauce
- 1 (14.5 ounce) can diced tomatoes, undrained
- 1 (8 ounce) can tomato sauce (ensure no added sugar)
- ½ cup chicken broth or vegetable broth
- 1 teaspoon dried oregano
- ½ teaspoon dried basil
- ¼ teaspoon red pepper flakes (optional, for a little heat)
- Salt and freshly ground black pepper to taste
For the Garnish (Optional)
- 2 tablespoons fresh parsley, chopped
- ¼ cup grated Parmesan cheese
Step-by-Step Instructions
-
Step 1: Brown the Sausage
Heat the olive oil in a large skillet or Dutch oven over medium-high heat. Add the Italian sausage. If using links, brown them on all sides. If using bulk sausage, break it up with a spoon as it cooks. Cook until the sausage is browned and cooked through, about 8-10 minutes. Remove the cooked sausage from the pan and set it aside on a plate, leaving any rendered fat in the skillet.
Small tip: Don’t overcrowd the pan when browning the sausage. If necessary, cook it in batches to ensure a good sear.
-
Step 2: Sauté the Vegetables
Add the sliced red bell pepper, green bell pepper, and yellow onion to the same skillet with the sausage drippings. Cook over medium heat, stirring occasionally, until the vegetables begin to soften, about 5-7 minutes. They should be tender-crisp.
-
Step 3: Add the Garlic
Stir in the minced garlic and cook for another minute until fragrant. Be careful not to burn the garlic, as this can make it bitter. The aroma will fill your kitchen beautifully!
-
Step 4: Build the Sauce
Pour in the diced tomatoes (with their juice), tomato sauce, and chicken or vegetable broth. Stir in the dried oregano, dried basil, and optional red pepper flakes. Bring the mixture to a gentle simmer.
-
Step 5: Combine and Simmer
Return the cooked sausage to the skillet with the vegetables and sauce. Stir everything together gently. Reduce the heat to low, cover the skillet, and let it simmer for 10-15 minutes. This allows all the flavors to meld together beautifully.
Small tip: Taste the sauce after simmering and adjust seasonings. Add more salt, pepper, or herbs as needed to suit your preference.
-
Step 6: Serve and Garnish
Once the sauce has thickened slightly and the flavors have deepened, remove the skillet from the heat. Ladle generous portions into bowls. Garnish with fresh chopped parsley and a sprinkle of grated Parmesan cheese, if desired. Serve immediately and enjoy!
Tips & Variations
- Gluten-Free Option: This recipe is naturally gluten-free! Just ensure your Italian sausage does not contain any gluten-based fillers. Most high-quality sausages are gluten-free, but always check the label.
- Vegan/Vegetarian Option: Easily transform this dish by swapping Italian sausage for plant-based Italian “sausage” or firm tofu, pressed and crumbled, seasoned with fennel and red pepper flakes. Use vegetable broth instead of chicken broth.
- More Veggies or Protein: Feel free to add sliced mushrooms, zucchini, or spinach during the last 5 minutes of simmering for extra nutrients. You can also add some cooked chicken breast or cannellini beans (if not strictly keto) for more protein.
- Spicy Version: If you love heat, increase the red pepper flakes to ½ teaspoon or more. You can also use hot Italian sausage for an extra kick! A dash of hot sauce at the end works too.
- Creamy Twist: For a richer, creamier sauce, stir in ¼ cup of heavy cream or cream cheese (keto-friendly!) during the last few minutes of simmering. It adds a lovely velvety texture.

Health Benefits
This Keto Italian Sausage and Peppers dish isn’t just delicious; it’s packed with wonderful health benefits too!
Bell Peppers: These colorful veggies are nutritional powerhouses. They are an excellent source of Vitamin C, which is crucial for immune function and skin health. They also contain Vitamin A, important for vision, and various antioxidants that help fight inflammation in the body.
Onions and Garlic: More than just flavor enhancers, onions and garlic are fantastic for your health. They contain sulfur-containing compounds that have been linked to heart health benefits and may have anti-inflammatory properties. Garlic, in particular, is known for its immune-boosting qualities.
Italian Sausage (Pork): When chosen wisely (look for lower sugar/carb options), Italian sausage provides a great source of high-quality protein, essential for muscle repair and growth. It also offers B vitamins like B12, important for energy metabolism, and minerals such as zinc and selenium, which support immune health.
Tomatoes: Even in canned form, tomatoes are rich in lycopene, a powerful antioxidant that gives them their red color. Lycopene is associated with heart health and may offer protection against certain types of cancer. They also provide Vitamin K and potassium.
This meal is also naturally low in carbohydrates and high in healthy fats and protein, making it incredibly satisfying and excellent for maintaining energy levels on a ketogenic diet.
Serving Suggestions
- As a Main Dish: This hearty dish is perfect on its own! Serve it in a bowl and enjoy every savory bite.
- With a Side: Pair it with a simple side salad dressed with olive oil and vinegar, or serve it over a bed of cauliflower rice to soak up all that delicious sauce.
- Keto “Hero” Sandwich: For a fun twist, spoon the mixture into a split, toasted keto hot dog bun or a large lettuce wrap for a low-carb “hero” sandwich experience.
- Meal Prep Powerhouse: Divide into individual meal prep containers for easy grab-and-go lunches or dinners throughout the week. It reheats beautifully!
Storage Tips
Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. This dish freezes exceptionally well!

To reheat, thaw overnight in the fridge (if frozen) and then gently warm in a skillet over medium-low heat, or microwave until heated through. You might need to add a splash of broth or water if the sauce has thickened too much.
