The seasoning is simple and clean, letting the ingredients really shine. It’s also flexible—use whatever sausage you like and the colors of peppers you have on hand.

What You’ll Need

• Italian sausage links (pork or chicken), 1 to 1.5 pounds; use mild or hot based on preference
• Bell peppers, 3 large (mix of red, yellow, and green), sliced into strips
• Yellow onion, 1 medium, sliced
• Garlic, 3 cloves, minced
• Olive oil or avocado oil, 1 to 2 tablespoons
• Tomato paste, 1 tablespoon (optional, adds richness with minimal carbs)
• Chicken broth, 1/3 cup (low-sodium)
• Italian seasoning, 1 teaspoon
• Crushed red pepper flakes, 1/4 teaspoon (optional)
• Salt and black pepper, to taste
• Fresh parsley or basil, chopped, for garnish
• Fresh lemon juice, 1/2 teaspoon (optional, brightens the flavors)

Step-by-Step Instructions

1. Prep the sausage and veg: Slice the bell peppers and onion into strips. Mince the garlic.
   

   If your sausage is in links, you can either leave them whole or cut them into 1-inch pieces. Both work; whole links feel traditional, sliced cooks faster.

2. Brown the sausage: Heat a large skillet over medium-high. Add a little oil.
   

   Place sausage in the pan and cook until browned on all sides, about 6–8 minutes. If cooking whole links, transfer to a plate and slice into thick coins once cool enough to handle.

3. Sauté the peppers and onions: In the same skillet, add another drizzle of oil if needed. Add the peppers and onions with a pinch of salt.
   

   Cook, stirring occasionally, until they soften and get some color, about 6–8 minutes.

4. Add garlic and seasoning: Stir in the garlic, Italian seasoning, and red pepper flakes. Cook 30–60 seconds until fragrant.
5. Build a quick pan sauce: Push the veggies to the sides. Add the tomato paste to the center and cook it for 30 seconds to concentrate the flavor.
   

   Pour in the chicken broth and stir, scraping up the browned bits on the pan. This creates a light, savory sauce.

6. Combine and simmer: Return the sausage to the skillet. Toss everything together.
   

   Reduce heat to medium-low and simmer 3–5 minutes, just until the peppers are tender and the sausage is cooked through. Add black pepper and salt to taste.

7. Finish and serve: Turn off the heat. Add a squeeze of lemon for brightness and sprinkle with chopped parsley or basil.
   

   Serve hot in bowls, over cauliflower rice, or in lettuce cups.

How to Store

Let leftovers cool, then store in an airtight container in the fridge for up to 4 days. Reheat gently on the stovetop over medium-low heat or in the microwave until warmed through. For longer storage, portion into freezer-safe containers and freeze for up to 2 months.

Thaw overnight in the fridge, then reheat with a splash of broth to loosen the sauce.

Benefits of This Recipe

• Keto-friendly and low-carb: Peppers and onions keep carbs modest while sausage provides satisfying fat and protein.
• Weeknight fast: From start to finish in about 30 minutes.
• Flexible and forgiving: Swap sausage types, pepper colors, or herbs without losing the spirit of the dish.
• Meal-prep friendly: Holds up well in the fridge and reheats beautifully.
• Big flavor, minimal ingredients: Browning and a quick pan sauce give you depth without a long ingredient list.

What Not to Do

• Don’t overcrowd the pan: Too much at once will steam the ingredients instead of browning them.
• Don’t skip salting the vegetables: A pinch of salt early helps draw out moisture and improves texture and flavor.
• Don’t overcook the peppers: You want them tender-crisp with a little bite, not mushy.
• Don’t forget to check labels: Some sausages and broths contain added sugars or fillers that can add unwanted carbs.
• Don’t drown it in sauce: A light pan sauce is plenty; heavy sauces can mask the fresh flavors and bump up carbs.

Recipe Variations

• Spicy Calabrian Kick: Add a teaspoon of Calabrian chili paste or extra red pepper flakes for more heat.
• Chicken Sausage Light: Use chicken Italian sausage and finish with extra olive oil for a leaner profile with balanced fat.
• Mushroom Boost: Add 1 cup sliced cremini mushrooms with the onions for extra umami and volume.
• Cheesy Bake: Transfer to a baking dish, top with shredded mozzarella and a sprinkle of Parmesan, and broil until bubbly.
• Herb Swap: Try oregano and thyme, or finish with chopped basil for a fresher, summery twist.
• Smoky Style: Use smoked sausage or add a pinch of smoked paprika to the pan sauce.
• Roasted Sheet Pan: Toss sliced sausage, peppers, onions, oil, and seasonings on a sheet pan and roast at 425°F (220°C) for 20–25 minutes, flipping once.

FAQ

Is this recipe truly keto?

Yes. The main carbs come from peppers and onions, which are moderate and portion-controlled. Choose a sausage with no added sugar and a low-carb broth to keep it keto-friendly.

Can I make it without tomato paste?

Absolutely.

The dish will still be flavorful. If skipping tomato paste, reduce the broth slightly or simmer a minute longer to keep the sauce from being too thin.

What’s the best sausage to use?

Italian pork sausage (mild or hot) offers the most classic taste. Chicken or turkey sausage works if you prefer lighter meat—just add a little extra oil so the dish stays satisfying on keto.

How can I add more fat for keto macros?

Finish with a drizzle of extra-virgin olive oil, toss in a tablespoon of butter at the end, or sprinkle on some shredded cheese before serving.

Can I meal prep this?

Yes.

It keeps well for several days, and the flavors meld nicely. Store in single-serve containers with cauliflower rice for ready-to-heat lunches.

What should I serve it with?

Cauliflower rice, zoodles, spaghetti squash, or simply a bed of sautéed greens. For extra texture, try crisp romaine or butter lettuce cups.

How do I keep the peppers crisp?

Cook them over medium-high heat and avoid overcooking.

They should soften and char slightly at the edges but still keep some bite.

Can I make it dairy-free?

Yes. The base recipe is dairy-free. Just skip any optional cheese finish and use olive or avocado oil.

Will it still work without onions?

It will.

Add an extra pepper for volume and a pinch more Italian seasoning. A small splash of balsamic vinegar (just a tiny amount) can mimic onion sweetness while staying mindful of carbs.

Can I cook the sausage in the air fryer first?

Yes. Air fry at 375°F (190°C) until browned and cooked through, then slice and toss with sautéed peppers and onions in the skillet with the sauce.
