Instant Pot Potato Soup

About this Recipe

My Mother is a master of potato soups of all kinds. When she got her hands on the Instant Pot … she was curious how it would compare with making soup in the soup pot. This Instant Pot Potato Soup Recipe turned out to be a really tasty alternative. It does mean getting all the ingredients in at the beginning and no adding extra ingredients to the soup pot which is a method she so often does.

My Grandma and Grandpa were the first of our clan to invest in the Instant Pot and instantly (!) were hooked, showing off with their quickly cooked meals and tender meats. At first my Mother and I were skeptical to get one for Grandmother’s Kitchen, but were lucky enough to be gifted with one for a birthday gathering. Now I can honestly say that for certain recipes, it has become a worthy tool that, yes, takes up some space, but really saves so much time in the kitchen. It is especially nice for cooking chicken and meats.

Grandmothers’ TIPS for Instant Pot Potato Soup Recipe:

1. Make sure you do NOT leave your meals cooking while you leave the home. Unless you have set it to slow cook, the settings are high pressure and so important to stick around. The good news is that it takes such a short time to cook that it is really no big deal to stay around.

2. Whatever you are cooking, the Instant Pot instructions say you need a minimum 1 1/2 cup of liquid to get to and maintain pressure. The liquid can be a water, juice, broth, wine or any other liquid you would like to flavor your cooking.

3. Look out for the MAX FILL line and do not go above it unless you like to clean up big messes.

4. Keep your face and skin AWAY from the steam when opening to avoid serious burns.

5. Do NOT use force to open the lid ever.

6. Locking the lid properly is important before any pressure cooking.

7. Get your own Instant Pot.



Makes: 6 Servings

1 Tablespoon butter, grapeseed or olive oil

1/2 large onion, diced

1 garlic clove, minced

3 cups water with one chicken bullion cube

1 box chicken broth (I used Pacific brand)

a few sprigs of dill chopped

7-8 medium to large russet potatoes, peeled and cut into 1 inch cubes

1 celery stalk, chopped

2 carrots chopped

1 1/2 teaspoons salt (more or less to taste)

1 cup milk (I used rice milk)

1 Tablespoon all purpose flour

green onions - Optional to sprinkle on top if desired

grated cheese - Optional to sprinkle on top if desired


1. Prepare all the vegetables, peeling and chopping and set aside.

2. Turn the instant pot onto sauté, add the butter, onions, celery and garlic and cook for a few minutes until soft.

3. Stir occasionally to keep from burning.

4. Add the water, chicken bullion cube and all the prepared vegetables.

5. Season with the salt and pepper.

6. Place the lid onto the instant pot and set the vent valve to ‘sealing’. Cook over manual high pressure for 10 minutes and when done quick release the pressure. This is very hot, so putting a damp tea towel over the valve and use an oven mitt to protect from getting burns. Once the steam has completely released and the pin has dropped open the lid.

7. Meanwhile stir together the milk and flour to form a ‘slurry’. I used a hand held blender to mix together to be sure there was no lumps in the flour.

8. Pour in the milk slurry.

9. Turn the pot to sauté and cook for 4-5 minutes until slightly thickened. Do a taste test and season to your own taste.

10. Serve the soup and add chopped green onions and grated cheese if desired.
