Ingredients Method

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.

FAQ

Is smoked sausage keto-friendly?

Most smoked sausages are keto-friendly, but always check labels.

Look for options without added sugars or fillers that increase carbs. Aim for 1–2 grams of carbs per serving or less.

Can I use raw sausage instead of fully cooked?

Yes, but brown it first to ensure it cooks through and develops flavor. Slice raw links, sear in a skillet until nicely browned, then add to the crockpot.

What can I serve this with to keep it low carb?

Cauliflower rice, roasted zucchini, sautéed cabbage, or mixed greens work well.

Lettuce cups are a fun handheld option if you want something light.

How can I thicken the sauce without adding carbs?

Uncover and cook on High for 15–20 minutes to reduce. You can also stir in a small knob of butter or cream cheese for body without adding flour.

Will frozen peppers work?

They’ll work in a pinch but can release more liquid and turn softer. If using frozen, reduce other liquids and plan for a slightly looser sauce.

Can I make this on the stovetop?

Yes.

Sauté the sausage, then cook peppers and onions until tender. Add seasonings, tomatoes, and paste. Simmer covered for 15–20 minutes, then uncover to reduce to your liking.

How spicy is this recipe?

Mild to medium, depending on your sausage and whether you add red pepper flakes.

Adjust heat to taste or skip the flakes for a gentle, kid-friendly version.

How many servings does this make?

It yields about 6 servings, depending on portion size and what you serve alongside. It’s easy to double in a larger slow cooker.
