  • 3 Small Bay Leaves
  • Salt and Black Pepper to Taste
  • ¾ Cup Frozen Peas

Instructions

  • In a 6-Qt or 8-Qt instant pot, combine the lentils, onion, carrot, celery, potatoes and zucchini.
    1 ½ Cups Brown Lentils, picked through and rinsed, 1 Large Onion, 2 Large Carrots, 2 Ribs Celery, 2 Medium Potatoes, Cubed, 1 Medium Zucchini
  • Then, add vegetable stock, olive oil, garlic, thyme, bay leaves ,and black pepper and stir.
    5 Cups Low Sodium Vegetable Stock, 2 Large Cloves of Garlic, Minced, 1 ½ teaspoon Dried Thyme Leaves, 3 Small Bay Leaves, Salt and Black Pepper to Taste, 2 tablespoon Olive Oil
  • Place the lid onto the instant pot and set it to high pressure for 7 minutes.
  • After 7 minutes has elapsed, turn the instant pot off and let it naturally release for 5-10 minutes. See Note
  • After 5-10 minutes, manually release the pressure by pressing the quick-release valve. After the pressure has been released, open the lid, add the frozen peas, and stir. The peas will warm up in a few minutes with the heat of the soup.
    ¾ Cup Frozen Peas
  • Taste the soup for seasoning and add additional salt and pepper if necessary. Let the soup cool a bit before serving. This stays very hot for a while.

Notes

Don't have zucchini? Swap it out for 1 ½ Cups of chopped mushrooms or chopped green beans.
My favorite vegetable stock is Better Than Bouillon Vegetable Base.
Natural release just means to turn the Instant Pot off and let it sit there for 5-10 minutes before pressing the button to quick-release the pressure.
To store, scoop the stew into containers that have airtight lids. Place in the refrigerator for up to 4 days or freeze for up to a month.
