This sausage and lentil soup is the perfect cozy dinner! It’s easy to make, absolutely good for you, and can handedly feed a hungry crew!
Why I Love This Recipe
This soup is hearty, easy to make, and makes a lot! This stew is packed with kale, lentils, Italian sausage, and tomato paste. This is nothing but flavorful comfort food in a bowl.

Ingredients in This Sausage and Lentil Soup
- Bulk spicy Italian sausage. If you can only find links, that’s totally fine. You’ll just need to remove the sausage from its casing.
- Mirepoix. called the trio of aromatics! Diced onion, celery and carrot lay the flavor foundation (and crunch) for this soup.
- Garlic. Fresh garlic is the way to go (always)!
- Tomato paste. This adds depth of flavor and body to the soup, though if you don’t have it, that’s OK.
- Brown or French green lentils. Either variety works here, just steer clear of red lentils and du Puy lentils (aka black beluga) lentils.
- Canned crushed tomatoes. Crushed tomatoes add nice body to the soup. For a brothier soup with chunks of tomato, use canned diced tomatoes with their juices.
- Worcestershire sauce. This is totally optional, but if you have it I recommend adding a splash. Worcestershire adds depth of flavor and savoriness to this soup.
- Kale. I prefer Tuscan kale here (also called Dinosaur or Lacinato). Regular kale will also work, as would any hardy green like Swiss chard or mustard greens.
- Parsley. A dose of freshness, though if you don’t have it on hand, no worries.

Step-by-Step Instructions for Making Sausage Lentil Soup
- Brown the sausage in a large pot or Dutch oven. Transfer the sausage to a bowl and reserve 1 tablespoon drippings in pot.
- Add mirepoix (onion, carrots and celery) and garlic to pot and cook until softened.
- Stir in tomato paste and cook 1 minute then stir in lentils, water, canned tomatoes and Worcestershire.
- Bring the soup to a boil, then reduce to a simmer and cook, partially covered with a lid, until the lentils are tender, about 30 minutes.
- Stir in kale by handful until wilted then stir in sausage and parsley.
- As always, season with additional salt and pepper to taste before serving.
TIP: I like to add a bit more water at the end to thin it out. If you would prefer this to be more like a stew, skip the added water at the end.
Slow Cooker Instructions
You can definitely cook this in a slow cooker. I would still cook the onions, carrots, celery and garlic on the stove top for a few minutes prior to adding them to the slow cooker with the lentils, tomatoes, water and Worcestershire. Cover and cook the soup on high for 3–4 hours or low for 6–8 hours until lentils are tender.
