Lets start by cutting leeks in half and chopping them. After you chop leeks place them in a big bowl and wash them with cold water until nice and clean.
Transfer bacon to a plate lined with paper towel, leave 2 tablespoons of bacon grease inside the Instant Pot. Now, add chopped leeks, cook for 5 minutes, stirring few times.
Also, into the same pot add salt and pepper to taste and 1/2 teaspoon dried thyme. Cover the lid and cook 10 minutes on a Soup/Broth mode. Make sure the steam release handle is in the ‘Sealing’ position.
Carefully, quick release the pressure by turning the steam release handle into venting position. Open the lid and serve Potato Leek Soup with bacon and fresh parsley. Enjoy!
