Easy One-Pan Keto Sausage & Peppers - Weeknight-Friendly Flavor
Ingredients
- 1 to 1.25 lbs Italian sausage links (mild or hot; pork or chicken)
- 3 bell peppers, mixed colors, sliced into strips
- 1 large yellow onion, halved and sliced
- 3 cloves garlic, minced
- 2 tbsp olive oil (or avocado oil)
- 1 tsp dried oregano
- 1/2 tsp dried basil (or Italian seasoning)
- 1/2 tsp smoked paprika (optional, for depth)
- 1/4–1/2 tsp red pepper flakes (optional, for heat)
- 1–2 tbsp red wine vinegar (or lemon juice), to finish
- Salt and black pepper, to taste
- Fresh parsley, chopped, for garnish
- Parmesan cheese, shaved or grated (optional, for serving)
Instructions
- Slice the veggies: Cut bell peppers into strips and slice the onion. Mince garlic and set aside.
- Brown the sausage: Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add sausage links and cook 3–4 minutes per side until well browned. Remove to a plate; they will finish cooking later.
- Sauté peppers and onions: Add the remaining oil to the same pan. Toss in peppers and onion with a pinch of salt. Cook 6–8 minutes, stirring occasionally, until softened with some caramelized edges.
- Add garlic and spices: Stir in garlic, oregano, basil, smoked paprika, and red pepper flakes. Cook 30–60 seconds until fragrant.
- Return sausage and simmer: Slice browned sausages into 1-inch pieces and add back to the skillet. Reduce heat to medium-low and cook 5–7 more minutes, stirring, until sausage is cooked through and veggies are tender.
- Brighten and season: Drizzle in red wine vinegar, toss, and taste. Add more salt, pepper, or vinegar as needed. Finish with chopped parsley.
- Serve: Enjoy as is, or plate over cauliflower rice or zucchini noodles. Sprinkle with Parmesan if you like.

Health Benefits
- Keto-friendly macros: Sausage provides protein and fat, while peppers and onions add fiber with relatively low net carbs.
- Rich in vitamins and antioxidants: Bell peppers are high in vitamin C and carotenoids that support immune health and eye health.
- Satiety and steady energy: The protein and fat combo helps keep you full and supports stable blood sugar.
- Simple, whole ingredients: No heavy sauces or fillers—just real food with clean seasoning.
Common Mistakes to Avoid
- Skipping the sear: Browning the sausage builds flavor. Don’t rush this step.
- Overcrowding the pan: If your skillet is small, cook in batches so vegetables caramelize instead of steam.
- Undercooking the onions: Give them time to soften for that classic sausage-and-peppers taste.
- Forgetting acidity: A splash of vinegar or lemon brightens the dish and balances the richness.
- Using sugary sausages: Some brands add sugar.
Check labels if you’re tracking carbs strictly.
Alternatives
- Sausage swaps: Use chicken sausage, turkey sausage, or spicy chorizo. For a lighter option, try uncooked Italian sausage removed from casings and crumbled.
- Veggie variations: Add mushrooms or zucchini in the last few minutes. Swap some onions for shallots for a sweeter finish.
- Spice tweaks: Use Italian seasoning, fennel seeds, or a touch of garlic powder.
For smoky heat, add chipotle powder.
- Saucy version: Stir in 1/2 cup low-sugar marinara at the end for a saucier skillet meal.
- Serving ideas: Pile onto spaghetti squash, cauliflower mash, or a bed of sautéed greens. For non-keto eaters, serve with crusty bread.
FAQ
Can I use pre-cooked sausage?
Yes. Slice and brown the sausage just until it gets color, then proceed with the recipe.
Reduce the final simmer time since it’s already cooked.
Is this spicy?
It depends on your sausage and whether you add red pepper flakes. Use mild sausage and skip the flakes for a gentle flavor, or choose hot sausage for more heat.
How many carbs are in this dish?
Exact numbers vary by brand and portion size, but a typical serving lands around 7–10g net carbs, mostly from peppers and onions. Check your sausage label for the most accurate count.
Can I make it dairy-free?
Absolutely.
The base recipe is dairy-free as written. Just skip the optional Parmesan garnish.
What kind of pan works best?
A large stainless steel or cast-iron skillet (10–12 inches) is ideal. It helps get that golden sear and gives veggies room to caramelize.
How do I prevent soggy peppers?
Use high heat, don’t overcrowd the pan, and avoid covering the skillet.
Stir occasionally, but let the veggies sit long enough to brown.
Can I add tomatoes?
Yes. Add a handful of cherry tomatoes in the last few minutes. They soften and burst without turning the dish watery.
How can I make it more filling without adding carbs?
Serve over cauliflower rice, zucchini noodles, or steamed broccoli.
You can also add extra sausage or mushrooms for volume.
