Ingredients

  • 1 tablespoon olive oil
  • 3 medium carrots, chopped into ¼" pieces
  • 1 small yellow onion, finely chopped
  • 2 ribs celery, finely chopped (with leaves)
  • 1 cup green lentils
  • 32 oz vegetable stock (can use chicken stock or beef stock as well)
  • 1 14.5 oz can fire roasted diced tomatoes
  • 1 teaspoon dried oregano
  • 1 teaspoon garlic powder
  • ½ teaspoon dried basil
  • 2 teaspoon ground cumin
  • ½ teaspoon crushed red pepper flakes
  • 1 ½ tablespoon apple cider vinegar (preferably organic)
  • salt and pepper, to taste

Instructions

  • In a 5 quart saucepan or stockpot, heat olive oil over medium-low heat.
  • Add celery, onion, and carrot- season with salt and pepper, and cook until slightly softened and translucent, about 7 minutes.
  • Add spices, stir to combine and cook until fragrant, about 1 minute.
  • Add rinsed lentils, fire roasted tomatoes, 1 tablespoon vinegar (reserve ½ tablespoon for end of cooking) and stock- turn heat to high and bring to a boil.
  • Reduce heat to low and cover. Cook on low until soup is thickened and lentils and veggies are fully cooked, 45 minutes.
  • Finish soup with salt and pepper to taste, stir in reserved ½ tablespoon apple cider vinegar and serve!

Notes

  • Lentils: No soaking needed. Rinse the green lentils before adding them to the pot.
  • Stock: Use vegetable stock to keep the soup vegan, or substitute chicken or beef stock if preferred.
  • Spice level: Reduce or omit the crushed red pepper flakes for a milder soup.
  • Vinegar: Add the apple cider vinegar at the end so it stays bright and doesn’t interfere with the lentils softening.
  • Consistency: The soup will thicken as it sits. Add a splash of stock or water when reheating if needed.
  • Storage: Refrigerate leftovers in an airtight container for up to 4 days.
  • Freezing: Freeze for up to 3 months, then thaw overnight in the refrigerator before reheating.
