Heat 1 tbsp olive oil in a large skillet over medium-high heat. Add 1 lb lean beef sausage, breaking it up, and cook until browned. Remove sausage, leaving drippings. Add 1 large yellow onion, 2 large carrots, and 2 celery stalks to the skillet; sauté for 5-7 minutes until softened.

Stir in 4 cloves minced garlic and 2 tbsp tomato paste into the skillet with the vegetables. Cook for another 1-2 minutes until fragrant, stirring constantly. This builds a rich flavor base for your Hearty Beef Sausage & Lentil Soup (Slow Cooker).

Transfer the browned sausage and sautéed vegetables to a 6-quart slow cooker. Add 1 1/2 cups rinsed brown or green lentils, 1 (28 oz) can diced tomatoes (undrained), 6 cups low-sodium beef broth, 1 tbsp Worcestershire sauce, 2 bay leaves, 1 tsp dried thyme, and 1/2 tsp smoked paprika.

Stir all ingredients well in the slow cooker. Cover and cook on low for 7-8 hours, or on high for 3-4 hours, until the lentils are tender and the flavors have melded. This slow cooking process is key for a truly Hearty Beef Sausage & Lentil Soup (Slow Cooker).
05 -
About 30 minutes before serving, stir in 4 cups chopped kale (tough stems removed) into the slow cooker. Replace the lid and continue cooking until the kale is wilted and tender, about 15-20 minutes.

Remove the bay leaves. Taste the Hearty Beef Sausage & Lentil Soup (Slow Cooker) and season generously with salt and black pepper to taste. Ladle into bowls and serve warm, perhaps with a crusty bread.
