Description

This hearty and flavorful Best Lentil Soup combines brown or green lentils with fresh vegetables like fennel, carrots, and spinach, enriched with fire roasted tomatoes and aromatic spices. A comforting, nutritious meal perfect for any season, easily prepared on the stovetop.


Ingredients

Scale

Vegetables

  • 1 medium yellow onion, diced
  • 1 fennel bulb, diced
  • 2 large carrots, peeled and diced
  • 3 cups baby spinach (or chopped standard spinach)
  • 1 clove garlic, grated

Liquids

  • ¼ cup olive oil
  • 28-ounce can diced fire roasted tomatoes
  • 1 quart vegetable broth
  • 1 cup water

Pantry & Spices

  • 1 ½ cups dry brown or green lentils
  • 1 teaspoon kosher salt
  • 1 tablespoon paprika
  • 1 tablespoon dried oregano


Instructions

  1. Prepare Vegetables: Dice the onion, fennel bulb, and peel and dice the carrots. Grate the garlic and set it aside to be stirred in after the soup is cooked.
  2. Sauté Vegetables: In a large pot, heat the olive oil over medium heat. Add the diced onion and fennel and sauté for 6 to 7 minutes until they become translucent and fragrant.
  3. Add Remaining Ingredients: Add the diced carrots, lentils, diced fire roasted tomatoes (with juices), vegetable broth, water, kosher salt, paprika, and dried oregano to the pot.
  4. Simmer Soup: Bring the mixture to a simmer over medium heat. Cover partially and let it cook for 22 to 25 minutes, or until the lentils are tender but not mushy.
  5. Finish and Serve: Stir in the baby spinach and the grated garlic, allowing the residual heat to gently wilt the spinach and infuse the garlic flavor. Let the soup rest for 5 minutes before serving. Adjust seasoning with additional salt and freshly ground pepper as desired. Serve immediately.
  6. Storage: Store leftover soup refrigerated for up to 4 days or freeze for 3 to 4 months.

Notes

  • You can substitute brown or green lentils interchangeably based on preference, but avoid red lentils as they cook differently.
  • Using fire roasted tomatoes adds a smoky depth to the soup; regular diced tomatoes can be used but will yield a milder flavor.
  • Grating the garlic instead of chopping provides a more even and subtle garlic infusion.
  • This soup freezes well, so consider making a double batch for easy meals later.
  • For a protein boost, add cooked sausage or chicken if not vegetarian.
