Equipment

  • measuring cups and spoons
  • colander
  • cutting board
  • sharp knife
  • Instant Pot (I used a 6-quart Instant Pot)
  • mixing spoon

Ingredients

  • 1 cup green lentils
  • 1⅓ cups Yukon gold potatoes diced (approximately 1 medium potato)
  • ½ cup red onion diced
  • ½ cup carrots diced
  • ½ cup celery diced (about 2 medium stalks)
  • 5 cloves garlic minced
  • 2 bay leaves
  • tablespoons tomato paste
  • ½ teaspoon dried oregano
  • ½ teaspoon dried thyme
  • ¼ teaspoon kosher salt
  • 3 cups low-sodium vegetable broth
  • ½ to 1½ tablespoons red wine vinegar (or more to taste)
  • freshly ground black pepper

Instructions

  • Soak lentils: Soak the lentils in water for at least 30 minutes while you chop the vegetables and measure the spices.
  • Fill the Instant Pot: Drain the lentils and add them to the Instant Pot. Add the potatoes, onion, carrots, celery, garlic, bay leaves, tomato paste, oregano, and thyme.
  • Add broth: Pour in the broth and stir, making sure all ingredients are submerged.
  • Cook: Lock the lid in place and set the Pressure Release knob to Sealing. Select Pressure Cook on High for 5 minutes and press Start.
  • Release pressure: After the 5-minute timer finishes and beeps, let the pressure release naturally for at least 10 minutes. Then, carefully switch the Pressure Release knob to Venting to release any remaining pressure.
  • Serve: When the float valve drops, open the lid, remove the bay leaves, and stir in ½ tablespoon of vinegar and freshly ground black pepper. Taste and adjust with more vinegar, pepper, or salt as needed. Serve hot and enjoy!
