how to make Instant Pot Lentil Soup

Ingredients:

  • 2 tablespoons extra-virgin olive oil
  • 1 medium yellow onion (chopped)
  • 2 celery stalks (chopped)
  • 2 cups chopped carrots (about 4 medium)
  • 6 kale leaves (stems finely diced, leaves chopped)
  • 4 garlic cloves (grated)
  • 1 (14-ounce) can diced fire-roasted tomatoes
  • ¾ cup uncooked green lentils
  • 2 tablespoons white wine vinegar
  • 12 fresh thyme sprigs (bundled)
  • 1½ teaspoons sea salt
  • Heaping ½ teaspoon ground cumin
  • Freshly ground black pepper
  • 6 cups vegetable broth
  • Red pepper flakes (optional)
  • ½ cup chopped fresh parsley (for garnish)
  • Grated Parmesan (for serving, optional)
  • Crusty bread (for serving)

Directions:

  1. Select the Sauté function on your Instant Pot. Set the level to medium and the time to 8 minutes.
  2. When the Instant Pot is preheated, drizzle the oil into the pot and add the onion, celery, and carrots. Cook for 8 minutes until the vegetables soften.
  3. Next, add the kale stems, garlic, tomatoes, lentils, vinegar, thyme bundle, salt, cumin, and several grinds of pepper to the pot. Stir everything together.
  4. Pour in the vegetable broth and secure the lid on the Instant Pot. Pressure cook on high for 15 minutes.
  5. Allow the Instant Pot to release pressure naturally for 20 to 30 minutes. When the float valve drops, remove the lid and stir in the kale leaves. Add a pinch of red pepper flakes and season with salt and pepper to taste.
  6. Remove the thyme bundle. Garnish with parsley and grated Parmesan if desired. Serve with crusty bread.
