Instant Pot Potato Soup. A simple potato soup, ready in under an hour thanks to pressure cooking.
- 2 tablespoons butter
- 1 medium onion, diced
- 1 clove garlic, crushed
- ½ teaspoon dried thyme
- ½ teaspoon fine sea salt
- 4 cups chicken broth (homemade or low-sodium store bought)
- 1 ½ teaspoons fine sea salt (if using homemade broth)
- 3 pounds of russet potatoes, peeled (about 6 medium potatoes), peeled and cut into 1-inch chunks
- 2 tablespoons corn starch
- 1 cup whole milk
- Shredded cheddar cheese
- Chopped green onion
- Chopped cooked bacon (or bacon bits), optional
- Sauté the onion, garlic, and thyme in butter: Melt the butter in an Instant Pot set to sauté mode - medium. (Use medium heat in other pressure cookers.) Add the onion and garlic, and sprinkle with the thyme and ½ teaspoon sea salt. Sauté until the onion softens, about 5 minutes, stirring and scraping often with a flat edged wooden spoon to make sure nothing sticks to the bottom of the pot.
- Potatoes and broth in the pot: Pour the chicken broth into the pot, then stir in the teaspoon of fine sea salt (if using homemade chicken broth) and add the potatoes.
- Pressure cook for 5 minutes with a Quick Release: Lock the lid and cook at high pressure for 5 minutes. (Use “manual” or “pressure cook” mode in an Instant Pot.) Quick release the pressure from the pot. After quick-releasing the pressure, remove the lid away from you – be careful, the steam is scalding hot.
- Simmer the cornstarch and milk slurry: Set the Instant Pot to sauté mode - medium again (medium-high heat on a stovetop), and bring the soup to a simmer. While the soup is heating, put the cornstarch in a small bowl, and slowly whisk in ¼ cup of the milk to make a cornstarch slurry. Once the soup is simmering, slowly stir the cornstarch slurry and the rest of the milk into the soup. Simmer the soup for 3 minutes to thicken the cornstarch.
- Serve: Ladle into bowls, sprinkle with the shredded cheddar, green onion, and (optional) bacon. Serve and enjoy!
