Lentil Sausage Soup

This soup has so much hearty flavor to it, it’s incredibly satisfying with those protein-packed lentils, savory sausage, vegetables, and optional add-ons like chopped kale or spinach.

Some of my most popular soup recipes include sausage, it just adds so much flavor. (Be sure to try my Sausage Tortellini Soup, Sausage and Potato Soup, and Zuppa Toscana recipes next!)

Also- don’t be thrown by the flavor enhancers in this recipe: Worcestershire sauce, hot sauce, and mustard powder. They add the best depth of flavor but you can’t detect them outright. They’re my favorite secret weapons in cooking.

How to Make It

See recipe card below this post for ingredient quantities and full instructions.

Cook and crumble the sausage over medium heat. Reserve 1 Tbsp. drippings and set the sausage aside. Sauté the onions, carrots, and celery in the reserved drippings and butter until softened. Add garlic and cook for 1 more minute, then add the flour and tomato paste and cook for 2 minutes.

Add the chicken and beef broth in splashes, and use a silicone spatula to “clean” the bottom of the pot to add more flavor to the soup.

Add the Worcestershire sauce, hot sauce, lentils, and seasonings. Bring to a boil, then reduce to a simmer. Cover partially and simmer for 45 minutes, stirring occasionally.

Add the sausage back to the soup along with the diced tomatoes. Simmer for 10 minutes. A little water or broth can be added to thin the soup out slightly if desired. Serve!

Best Lentils for Lentil Soup

  • Dry Brown or French Green Lentils are best in lentil soup. Red lentils and canned lentils won’t hold up well.
  • Note that green lentils take longer to cook due to their tougher exterior.
  • I use Goya brown lentils in this recipe.

Pro Tips

  • Chopped Kale or Spinach make great additions to this soup. Kale can be added during the last 5 minutes, spinach during the last 3 minutes.
  • The Worcestershire sauce, hot sauce, and mustard powder can’t be tasted outright but act as flavor enhancers in this soup. The hot sauce doesn’t make it spicy, this is the hot sauce I use.
  • Low Sodium broth may be used if desired as sausage also contains salt.
  • For brothier soup, use 3/4 lb. or 1/2 lb. sausage.
  • Ground Turkey can be used instead of sausage for a lighter option.

Storage

  • Store in an airtight container and refrigerate for up to 3 days or freeze for up to 3 months. This soup freezes very well for future meals.

Instructions

  • Cook the Sausage: Remove the casings from the sausage if you purchased links. Preheat a large pot over medium heat. Add the sausage and cook and crumble to break it apart.

Set the sausage aside on a paper towel lined plate. Reserve 1 tablespoon drippings. (Butter can be used if you don’t have drippings.)

  • Add the flour and tomato paste and cook for 2 minutes. Add the chicken and beef broth in splashes, and use a silicone spatula to “clean” the bottom of the pot to add more flavor the soup.
  • Add the Worcestershire sauce, hot sauce, lentils, bay leaf, and seasonings. Bring to a boil, then reduce to a simmer. Cover partially and simmer for 45 minutes, stirring occasionally.
  • Add the sausage back to the soup along with the diced tomatoes, Simmer for 10 minutes. A little water or broth can be added to thin the soup out slightly if desired. Serve!

Notes

Pro Tips:
  • Chopped Kale or Spinach make great additions to this soup. Kale can be added during the last 5 minutes, spinach during the last 3 minutes.
  • The Worcestershire sauce, hot sauce, and mustard powder can't be tasted outright but act as flavor enhancers in this soup. The hot sauce doesn't make it spicy, this is the hot sauce I use.
  • Low Sodium broth may be used if desired as sausage also contains salt.
  • For brothier soup, use 3/4 lb. or 1/2 lb. sausage.
  • Ground Turkey can be used instead of sausage for a lighter option.
  • Green lentils may also be used for this recipe, however they take longer to cook due to their tougher exterior. Canned or Red lentils shouldn't be used for this recipe.
Crock Pot Method
  • Note: Reserved sausage drippings and flour are not needed for this method. 
  • Brown the sausage in a skillet as outlined and transfer to a paper towel lined plate.
  • Meanwhile, melt 2 tablespoons butter in the Crock Pot and add the diced onions, carrots, celery, garlic, and tomato paste. Toss to coat.
  • Add the cooked sausage, Worcestershire sauce, hot sauce, lentils, seasonings, diced tomatoes, and chicken/beef broth. 
  • Cover and cook on high for 4-5 hours or on low for 7-8.
  • Note: Higher altitudes may require more cooking time and crock pot temperatures do vary. Opening the crock pot during cooking will set the time back at least 30 minutes as heat escapes when the lid is removed.
