Ingredients
  

  • 1.5 pounds fully cooked smoked sausage (kielbasa, andouille, or bratwurst), sliced into 1/2-inch rounds
  • 3 bell peppers (mix of red, yellow, and green), sliced into thick strips
  • 1 large yellow onion, sliced into thick wedges
  • 3 cloves garlic, minced
  • 1 (14.5-ounce) can diced tomatoes, drained well (look for no-sugar-added)
  • 2 tablespoons tomato paste (no-sugar-added)
  • 1 tablespoon smoked paprika
  • 1 teaspoon dried oregano
  • 1/2 teaspoon crushed red pepper flakes (optional, adjust to taste)
  • 1/2 teaspoon ground black pepper
  • 1/2 teaspoon sea salt (adjust based on your sausage’s saltiness)
  • 2 tablespoons olive oil
  • 1 tablespoon red wine vinegar (or apple cider vinegar)
  • Fresh parsley, chopped, for garnish
  • Optional finishes: 1–2 tablespoons butter for gloss, grated Parmesan for serving

Method
 

  1. Prep the produce: Slice peppers into thick strips and the onion into wedges. Mince garlic. Keep the pieces on the thicker side so they hold up during slow cooking.
  2. Slice the sausage: Cut into 1/2-inch rounds. If you like lightly crisp edges, brown them in a skillet with 1 tablespoon olive oil for 3–4 minutes first. This step is optional but adds great flavor.
  3. Build the base: In the crockpot, add sliced peppers, onion, garlic, diced tomatoes (drained), and tomato paste. Drizzle with remaining olive oil.
  4. Season: Sprinkle in smoked paprika, oregano, crushed red pepper, black pepper, and salt. Stir gently to coat the vegetables.
  5. Add the sausage: Place sliced sausage on top, then pour in the red wine vinegar. The vinegar brightens the sauce and balances the richness.
  6. Cook low and slow: Cover and cook on Low for 5–6 hours or on High for 2.5–3 hours. Aim for tender peppers and onions and a cohesive, slightly thickened sauce.
  7. Finish the sauce: Taste and adjust seasoning. For extra richness, stir in butter until melted. If the sauce seems thin, uncover and cook on High for 15–20 minutes.
  8. Garnish and serve: Top with chopped parsley. Serve as is, over cauliflower rice, over sautéed cabbage, or in lettuce cups. Sprinkle with Parmesan if desired.
