Italian Lentil Soup with Sausage

This soup uses a Parmesan rind simmered in the broth to add depth without overdoing it. The balsamic at the end ties together the sweetness from the tomatoes and the richness from the sausage.

Ingredients (~6 servings)

  • 1 cup dry green or brown lentils, sorted and rinsed
  • 1 lb ground Italian sausage (pork or turkey, sweet/mild/hot)
  • 2 Tbsp olive oil
  • 1 medium onion, diced (~1 cup)
  • 2 large carrots, peeled and chopped (~1 cup)
  • 2 medium celery ribs, chopped (~3/4 cup)
  • 5 cloves garlic, minced
  • 2 Tbsp tomato paste
  • 3/4 cup dry white wine
  • 1 tsp dried basil
  • 1 tsp dried oregano
  • 1/2 tsp dried parsley
  • 1/2 tsp dried thyme leaves
  • 1/4 tsp crushed red pepper
  • 1/4 tsp garlic powder
  • 1/4 tsp ground black pepper
  • 8 cups reduced-sodium chicken broth
  • 1 can (14.5 oz) diced tomatoes, undrained
  • 1 oz piece of Parmesan or Pecorino Romano rind
  • 2 bay leaves
  • 2 well-packed cups bite-size chopped Lacinato kale
  • 1-2 Tbsp balsamic vinegar
  • Salt to taste
  • Grated Parmesan for serving

Sort and Rinse the Lentils

Pour 1 cup of lentils onto a plate and pick through them.

Toss any rocks, wrinkled lentils, or anything that looks off.

Rinse well in a sieve under cool water and set aside.

Brown the Sausage

Add 1 lb of Italian sausage to a large soup pot over medium heat.

Break it up with a wooden spoon and cook until fully browned and crumbly – this takes ~9-10 minutes.

Transfer the cooked sausage to a paper towel-lined plate to drain.

Wipe out the grease from the pot with a paper towel; you’ll use the same pot for the soup.

Sauté the Vegetables

Add 2 Tbsp of olive oil to the empty pot over medium heat.

Once the oil is shimmering, add the 1 cup diced onion, 1 cup chopped carrots, and 3/4 cup chopped celery.

Sauté for ~6-8 minutes until the vegetables are softening but not browned.

Add the 5 cloves minced garlic and 2 Tbsp tomato paste.

Cook for ~3 minutes, mashing the tomato paste into the vegetables as you stir – the paste should darken slightly and smell sweet.

Deglaze with Wine

Pour in 3/4 cup white wine and let it simmer for ~1-2 minutes.

Use a wooden spoon to scrape up any stuck-on bits from the bottom of the pot – these are flavor.

Stir everything together so the wine incorporates with the vegetables.

Add the Seasonings and Build the Soup

Add 1 tsp basil, 1 tsp oregano, 1/2 tsp parsley, 1/2 tsp thyme, 1/4 tsp crushed red pepper, 1/4 tsp garlic powder, and 1/4 tsp black pepper.

Stir to coat the vegetables evenly with the spices.

Pour in 8 cups of chicken broth and the can of diced tomatoes with their juice.

Add the cooked sausage, 1 oz Parmesan rind, 2 bay leaves, and the sorted lentils.

Stir everything together.

Simmer Until the Lentils are Tender

Bring the soup to a boil over medium-high heat, then reduce to a constant simmer.

Partially cover the pot with a lid – leave a large crack open so steam can escape and the soup can reduce.

Simmer for ~45 minutes, stirring occasionally.

The lentils should be tender and soft when you bite into one; if they’re still firm, keep simmering.

Add the Kale

Fish out and discard the bay leaves – they should be floating near the top.

Add 2 cups of chopped kale and simmer uncovered for ~7-8 minutes until the kale is tender and wilted.

Finish with Balsamic and Adjust Seasoning

Stir in 1 Tbsp balsamic vinegar and taste.

If you want more acidity, add another 1 Tbsp – the balsamic should brighten the soup without tasting like vinegar.

Taste for salt and add if needed; the broth and Parmesan rind usually provide enough but it depends on your broth.

Serve with crusty bread and grated Parmesan on top.
