Heat 1 tbsp olive oil in a large skillet over medium-high heat. Add 1 lb mild or hot Italian sausage (casings removed) and cook, breaking it up, until browned. Drain any excess fat from the skillet and set the browned sausage aside.
02 -
In the same skillet (or a clean one), add 1 large yellow onion, diced, and cook until softened, about 5 minutes. Stir in 4 cloves garlic, minced, and cook for 1 minute more until fragrant, being careful not to burn the garlic.

Transfer the browned sausage, sautéed onion, and garlic to a 6-quart slow cooker. Add 2 large carrots, peeled and diced, 2 stalks celery, diced, and 1 (28 oz) can diced tomatoes, undrained. This forms the initial layer for your Slow Cooker Sausage and Lentil Soup Recipe.
04 -
Add 1 tsp dried thyme, 1 bay leaf, 1 1/2 cups dry brown or green lentils (rinsed), 6 cups low-sodium chicken broth, and 1 tbsp Worcestershire sauce to the slow cooker. Stir well to combine all ingredients for your Slow Cooker Sausage and Lentil Soup Recipe.
05 -
Cover the slow cooker and cook on LOW for 6-8 hours or on HIGH for 3-4 hours, until the lentils are tender and the vegetables are soft. This slow cooking process ensures a rich and flavorful Slow Cooker Sausage and Lentil Soup Recipe.
06 -
Once cooking is complete, remove and discard the bay leaf. Stir in 4 cups chopped kale (stems removed) until wilted, which typically takes about 5-10 minutes. Season the Slow Cooker Sausage and Lentil Soup Recipe generously with kosher salt and freshly ground black pepper, to taste. Garnish with 1/4 cup fresh parsley, chopped, before serving.
