Dive into the world of hearty vegetarian soup with this Instant Pot Lentil Soup – no soaking required. Lentils, the unsung heroes of a quick weeknight dinner, effortlessly transform in the Instant Pot, creating a culinary revelation.

In just 15 minutes of cook time (plus pressure build-up time), you’ll have a comforting bowl that defies the need for pre-soaking. Picture the beauty of lentils mingling with wholesome ingredients, showcasing the Instant Pot’s efficiency.

Prep is a breeze – dice an onion, carrots, and celery, and sauté them in the Instant Pot with olive oil. Add minced garlic for flavor, then toss in rinsed lentils, diced tomatoes, vegetable broth, and a blend of spices. Ground cumin, coriander, smoked paprika, and a bay leaf come together for robust flavors.

Seal the Instant Pot and set it to pressure cook for 15 minutes. As it works its magic, you’re free to attend to other tasks. When the timer dings, let the pressure release naturally for 10 minutes, unveiling a fragrant soup.

Resting for 10 minutes after cooking allows the flavors to meld, enhancing the taste. Serve this soup as a main course, garnished with fresh parsley if desired. For an extra zing, offer lemon wedges on the side.

  • Instant Pot
  • Chopping board
  • Knife
  • Ladle
  • Wooden spoon
  • Measuring cups and spoons


  • 1 cup dry green or brown lentils rinsed
  • 1 large onion diced
  • 3 carrots diced
  • 3 celery stalks diced
  • 3 cloves garlic minced
  • 1 can (14 oz ) diced tomatoes
  • 6 cups vegetable broth
  • 2 teaspoons ground cumin
  • 1 teaspoon ground coriander
  • 1 teaspoon smoked paprika
  • 1 bay leaf
  • Salt and pepper to taste
  • 2 tablespoons olive oil
  • Fresh parsley for garnish (optional)
  • Lemon wedges for serving (optional)


  • Start by rinsing the lentils under cold water and set them aside.
  • Turn on the Instant Pot and set it to “Sauté” mode. Add olive oil and sauté the onions, carrots, and celery until they start to soften, about 5 minutes.
  • Add minced garlic and continue sautéing for another 1-2 minutes until fragrant.
  • Pour in the diced tomatoes, lentils, vegetable broth, ground cumin, ground coriander, smoked paprika, bay leaf, salt, and pepper. Stir well to combine.
  • Close the Instant Pot lid and set the valve to the sealing position. Cancel the “Sauté” mode and set the Instant Pot to “Manual” or “Pressure Cook” mode for 15 minutes.
  • Once the cooking time is complete, allow the Instant Pot to release pressure naturally for 10 minutes. Then, carefully switch the valve to the venting position to release any remaining pressure.
  • Open the lid and give the soup a good stir. Adjust salt and pepper according to your taste.
  • Let the soup rest for about 10 minutes before serving. This allows the flavors to meld.
  • Ladle the soup into bowls, garnish with fresh parsley if desired, and serve with lemon wedges on the side.
