Ingredients

Scale

Vegetables and Aromatics

  • 2 tablespoons extra-virgin olive oil
  • 3 medium carrots, peeled and diced
  • 1 small sweet onion, diced
  • 3 cloves garlic, minced
  • 1/8 teaspoon crushed red pepper flakes
  • Salt and pepper, to taste

Main Ingredients

  • 2 cups dried red lentils, rinsed
  • 6 cups low-sodium chicken broth
  • 6 ounces kielbasa, cut into small bite-sized pieces

Seasonings and Finishing Touches

  • 1/2 teaspoon salt
  • 1/2 tablespoon dried Italian herbs
  • 2 & 1/2 tablespoons lemon juice

Instructions

  1. Prepare Crockpot: Coat a 6-quart crockpot with nonstick cooking spray to prevent sticking during the slow cooking process.
  2. Sauté Vegetables: Heat olive oil in a large nonstick skillet over medium-high heat. Add diced carrots and onion, sautéing for 4-5 minutes until tender. Add minced garlic and cook for about 20 seconds until fragrant. Season with crushed red pepper flakes, salt, and pepper.
  3. Combine Ingredients in Crockpot: Transfer the sautéed vegetable mixture to the crockpot. Add rinsed red lentils, low-sodium chicken broth, kielbasa pieces, and 1/2 teaspoon salt. Stir everything together, then cover the crockpot.
  4. Slow Cook the Soup: Cook the soup on low heat for approximately 5 and 1/2 hours, or until the lentils are tender and the flavors have melded beautifully.
  5. Finish and Season: Stir in dried Italian herbs and lemon juice. Taste the soup and adjust seasoning with additional salt and pepper if needed.
  6. Serve: Ladle the soup into bowls and enjoy on its own or with a side of crusty bread for a complete meal.

Notes

  • For a vegetarian version, substitute chicken broth with vegetable broth and omit the kielbasa or replace it with plant-based sausage.
  • Rinsing lentils before cooking helps remove debris and reduces foaming.
  • Adjust the amount of crushed red pepper flakes based on your preferred spice level.
  • Leftovers can be refrigerated for up to 4 days or frozen for up to 3 months.
  • Lemon juice added at the end brightens the flavor and balances the richness of the kielbasa.
