How to Make Potato Soup in an Instant Pot
There are just a few simple steps to make the best Instant Pot potato soup. I’ll give you my best tips to make sure your soup turns out perfect!
The first step is to sauté the aromatic ingredients, which in this soup are onion and garlic. I like to cook the onion in a little butter, because I like the flavor that the butter adds to the soup. You can use olive oil if you prefer.
Once the onion is soft, you’ll add some minced garlic to the pot. You’ll want to press cancel to turn off the Instant Pot’s sauté mode right after adding the garlic, since it takes a few minutes for the pot to cool down. (You can always remove the inner pot from the base if you need it to cool more quickly. Be sure to use oven mitts because the inner pot will be hot.)
Before adding the remaining ingredients, you need to deglaze the pot to remove any browned bits that might be stuck to the bottom. All you have to do is pour in a little bit of broth and scrape up any bits from the bottom of the pot.
Next, you will add the remaining ingredients and pressure cook the soup for 6 minutes on manual. The Instant Pot will take a few minutes to come to pressure and then the cook time will begin counting down. When the cook time ends, you will let the pot release naturally for about 10 minutes before quick releasing any remaining pressure.
Once the steam and pressure have all been released and the pin drops down, it is safe to take the lid off of the pot. Now all that you need to do is mash some of the potatoes and thicken your soup!
This soup thickens really well, using the Instant Pot’s sauté mode. You’ll stir in a slurry of milk and cornstarch and then stir the soup until it is as thick as you want it. If you are making this soup ahead, keep in mind that it will thicken as it cools. Use a potato masher or wooden spoon to mash some of the potatoes. I like to leave some whole potato pieces in the soup for texture.
How to make Loaded Baked Potato Soup in your Pressure Cooker
To make Instant Pot loaded baked potato soup, all that you need to do is load up your bowl of soup with your favorite baked potato toppings. Try these potato soup toppings:
- cooked, crumbled bacon
- shredded cheese
- sliced green onions or chives
- sour cream or plain Greek yogurt
Cooking Tips for Instant Pot Potato Soup
- Use Yukon gold potatoes to make the best potato soup. Gold potatoes are waxy and buttery, with a low starch content. Their creamy, moist texture will give your potato soup the best thick, creamy and smooth texture.
- Chop your potatoes into 1/2-inch size pieces, so that they will cook in the time given in the recipe.
- To make Instant Pot potato leek soup, you can add 1 large or 2 small leeks to this recipe. Slice and wash the leeks and sauté them with the onion.
- To make your soup dairy-free, substitute unsweetened, unflavored almond milk in place of the whole milk. Use olive oil instead of butter.
- To make vegetarian potato soup, use vegetable broth and keep your toppings vegetarian.
Instant Pot Potato Soup
- 1 tablespoon butter
- 1 cup chopped yellow onion
- 3 cloves garlic (minced)
- 2.5 pounds Yukon gold potatoes (cut into 1/2-inch pieces)
- 2 carrots (sliced)
- 1/2 teaspoon dried oregano
- 3/4 teaspoon salt (or to taste)
- 1/4 teaspoon black pepper (or to taste)
- 1/4 teaspoon cayenne pepper (optional, for spice)
- 2.5 cups low sodium vegetable broth (or chicken broth)
After Pressure Cooking:
- 1 cup milk (whole milk preferred)
- 1 tablespoon cornstarch
Optional Toppings, for Serving:
- shredded cheddar cheese
- cooked crumbled bacon
- sliced green onions or chives
- Press the Saute button on your Instant Pot to turn on saute mode. Add the butter to the pot. When the Instant Pot is hot, add the onion and cook, stirring often, until onion has softened, about 3 minutes.
- Add the garlic to the pot and press Cancel to turn off the Instant Pot. Stir for 30 seconds.
- Pour in a little bit of the broth and stir, scraping up any browned bits stuck to the bottom of the Instant Pot. Add the potatoes, carrots, oregano, salt, pepper, cayenne (if using) and remaining broth to the Instant Pot. Stir.
- Close the Instant Pot lid and turn the steam release valve to the sealing position. Using the Manual/Pressure Cook function, set the cook time to 6 minutes. The Instant Pot will take about 15 minutes to reach pressure and then the cook time will begin counting down.
- When the cook time ends, allow the pot to naturally release for 10 minutes by just letting it sit. After the 10 minute natural release, use the handle of a long spoon to carefully turn the steam release valve to the venting position. Once all of the steam escapes and the pin drops down, carefully open the Instant Pot lid.
- In a small bowl or liquid measuring cup, stir together the 1 cup milk and 1 tablespoon cornstarch. Turn the Instant Pot on saute mode and stir in the milk and cornstarch mixture. Use a potato masher to mash some, but not all, of the potatoes. Let the soup simmer, stirring, until it thickens slightly.
- Press cancel to turn the Instant Pot off. Serve the soup with toppings, as desired.
- You can make this potato soup up to 3 days ahead. It reheats well. When you are thickening the soup, keep in mind that it will continue to thicken as it cools.
