Italian Lentil Soup

Italian Lentil Soup features brown or green lentils simmered with carrot, celery, onion, tomato paste, and plum tomatoes, flavored with oregano and optionally enriched by a Parmesan rind. After cooking, baby spinach is stirred in for freshness. The soup offers a tender lentil texture with savory tomato and herb notes, balanced by earthy vegetables and a finishing drizzle of olive oil or grated cheese if desired.

Description

This Italian Lentil Soup starts by gently sautéing diced onion, celery, and carrots in extra virgin olive oil until soft. Tomato paste is added and cooked to develop depth, followed by crushed plum tomatoes, dried oregano, lentils, water, and optionally a small Parmesan rind for richness. The soup is simmered until lentils are tender, then fresh baby spinach is stirred in, wilting with residual heat.

The resulting soup offers a wholesome combination of tender lentils with aromatic vegetables and a slightly tangy tomato base. The inclusion of Parmesan rind adds a subtle savory complexity that complements the mild peppery flavor of the lentils. This soup is filling and packed with plant-based protein and fiber.

It is traditionally served in bowls, often accompanied by crusty bread and optionally topped with a drizzle of olive oil or grated cheese. A splash of red wine vinegar can be added at serving to brighten the flavors.

The soup can be made ahead and stored for up to three days in the refrigerator, and it also freezes well for up to three months. Reheat gently to preserve texture and flavor.

Notes

  • Both brown and green lentils can be used; brown lentils cook quicker and have a milder flavor than green lentils.
  • Parmigiano Reggiano rind adds depth to the soup but can be omitted; serve with grated cheese if unavailable.
  • Finish with extra virgin olive oil or red wine vinegar for added flavor.
  • Store leftovers in the refrigerator for up to 3 days or freeze for up to 3 months; reheat in the microwave.
