We’ve all been there: We’re running low on pantry items but still want something hearty and satisfying for dinner. Or we just don’t want to spend much time in the kitchen. Either way, this comforting Italian lentil soup with pasta is made for those moments (as is this similar lentil soup).

This recipe doesn’t call for many ingredients. There are no carrots and celery, unless you want them, and it relies on pantry standbys like lentils, pasta, and tomato paste. It’s not, however, short on flavor.

Thanks to the red lentils, this soup also cooks quickly, and you can easily have it on the table in 30 minutes—or 25 if you prep ingredients faster than I do.

Pro Tips

Rinse lentils right before adding to the pot: Red lentils tend to clump if you let them sit after rinsing.

Variations & Substitutions

-Add one diced celery rib and one diced carrot to the onion and garlic.
-Replace the onion with a shallot.
-Use any small pasta you like, such as small pasta shells, elbows, or farfalline.
-Stir in some leafy spinach near the end for more color and nutrients.
-Use chicken broth or stock for a richer flavor, unless you want to keep it vegetarian.
-Use brown or green lentils instead. These lentils require more cooking time, so hold off on adding the pasta until the lentils have a few minutes left to cook fully. You may also need to add up to another cup of liquid. You can use water to make up the difference.

Recipe FAQs

Can I make this soup ahead of time?

Yes, and there’s not a lot of pasta in the soup, so it won’t absorb the liquid as much as other pasta soups might.

Do red lentils taste different than brown lentils?

Yes, they taste milder and slightly sweeter than brown lentils.

Why do red lentils turn mushy when cooked?

They turn mushy because, unlike other lentils, their seed coat is removed.

Storage

Refrigerator: Store in an airtight container in the fridge for 3-4 days.
Freezer: Freeze in a freezer-safe container for up to 2 months.
Reheat: Warm through in a pot on the stovetop or in a microwave-safe container in the microwave. If taking from the freezer, defrost in the refrigerator first before reheating.

Ingredients
  

  • 2 tablespoons extra virgin olive oil
  • cup yellow onion peeled and minced
  • 3 garlic cloves peeled and minced
  • 1 tablespoon tomato paste
  • 4 cups low-sodium vegetable broth
  • 1 cup red lentils rinsed (Note 1)
  • cup ditalini pasta rounded cup
  • 1 bay leaf
  • 1 teaspoon kosher salt
  • Ground black pepper
  • Pinch red pepper flakes
  • Grated Pecorino Romano cheese
  • Handful Italian flat-leaf parsley minced (optional)

Instructions
 

  • Heat the olive oil in a medium-sized pot over medium-low to medium heat. Add the onion and garlic and saute for about 2 minutes until the onion becomes soft and translucent. Stir often so the onion and garlic don't darken too much.
  • Add the tomato paste and cook for 30 seconds to 1 minute, stirring constantly, to cook out the raw tomato flavor.
  • Pour in the broth, cover the pot, and raise the heat to high to bring the broth to a boil. Stir in the lentils and pasta along with the bay leaf, salt, black pepper, and red pepper flakes. Reduce the heat to a gentle simmer. Cover the pot with a lid so that it's mostly covered, but not entirely.
  • Simmer for 10-15 minutes, until the pasta is al dente and the soup has thickened. Remove bay leaf. Ladle the soup into bowls and garnish with the Pecorino and parsley, if using. Enjoy!

Notes

Note 1: Rinse the lentils right before you add them to the pot. Red lentils sometimes clump together if you rinse them and let them sit.
