  • Total Time: 6 hours 50 minutes
  • Yield: 6 servings

Ingredients

Scale
  • 1 lb dried red kidney beans, soaked overnight (or 2 (15 oz) cans red kidney beans, drained and rinsed)
  • 8 oz andouille sausage, sliced
  • 1 tbsp olive oil
  • 1 medium onion, diced
  • 1 green bell pepper, diced
  • 2 celery stalks, diced
  • 3 garlic cloves, minced
  • 1 tsp smoked paprika
  • 1 tsp cayenne pepper (adjust to taste)
  • 1 tsp dried thyme
  • 1 tsp dried oregano
  • 1 bay leaf
  • 4 cups low-sodium chicken broth
  • Salt and black pepper to taste
  • Fresh green onions, for garnish
  • 2 cups cooked white rice, for serving

Instructions

  1. If using dried beans: rinse and soak overnight. Drain and place in slow cooker.
  2. Heat olive oil in a skillet over medium heat. Brown sausage slices for 3–4 minutes. Add onion, bell pepper, and celery; cook 5 minutes until softened. Stir in garlic and spices; cook 1 minute.
  3. Transfer sautéed mixture to slow cooker. Add soaked beans, broth, and bay leaf. Cook on LOW 6–7 hours (or HIGH 3–4 hours) until beans are tender.
  4. For canned beans: skip soaking and add beans with sautéed mixture. Cook on LOW 2–3 hours.
  5. Remove bay leaf. Season with salt, pepper, and extra cayenne if desired. Serve over rice and garnish with green onions.

Notes

  • For vegetarian version, omit sausage and add 1 cup cubed sweet potato + 1 tsp liquid smoke.
  • Beans thicken as they cool—add extra broth or water when reheating.
  • Make ahead and refrigerate for up to 4 days or freeze for 3 months.
