I love to add leeks, sweet potatoes, and pumpkin to my potato soup. You would sauté the leeks with the garlic and scrub, peel and cube the sweet potato, turnips, and or pumpkin, decreasing one potato for the add-on. Use 1/2 cup up to one cup of diced pumpkin, sweet potatoes, or turnips to replace one potato.
This is an easy recipe, add more potatoes, vegetables to your liking. Ensure you have at least 2-3 inches of liquid covering the vegetables in the Instant Pot.

Creamy or Chunky Potato Soup?
Our house prefers chunky soup. In order to have a few chunks of potatoes or add-ons, remove about a cup of cooked potatoes or add-ons before using the immersion blender to blend the soup, right in the Instant Pot. Gently stir the potatoes back in the soup once the immersion blending is completed.
How to Thicken Potato Soup Without Flour
Powdered milk is a good thickener for potato soup as well as 100% natural instant potato flakes. Stir the powdered milk into the soup while it’s hot. If you want a thickened vegan soup, try using about 2 tablespoons of cornstarch or arrow root whisked in cold water before adding to the hot soup to eliminate lumps.
Potato Soup Not Using the Instant Pot
If you choose to make the soup on the stove-top, that’s easy too. Sauté the onions, garlic, celery, and optional leeks in a pot. Gently boil the soup until the potatoes are fork-tender. This takes around 15-20 minutes. (If you are not partial to boiling; steaming or microwaving the potatoes is another method to cook the vegetables). Add the rest of the ingredients to the drained potatoes. Use the immersion blender or use a potato ricer to “mash the potatoes” and still well into the soup. Garnish with fresh or dried parsley.
What spices to add to potato soup?
Our favorite spice to sprinkle on the soup is garam masala. It gives it just the right amount of flavor. If you would like to make your own spice, I have a whole blog post on How to Make and Use Garam Masala.
Potato Soup Ideas
When it comes to soup, we are big-time bread eaters. I love any type of bread. In the summer I will make buttermilk biscuits. You can see the blog, recipe, and video on Homemade Flaky Biscuits From Scratch for Two. During the cooler months of the year, I prefer yeast rolls like buttermilk rolls, which you can find at Easy Buttermilk Wheat Bread Machine Rolls.
How Long Does Potato Soup Last in the Fridge?
Once I finish eating the soup and while it is still hot, I put it in a canning or Weck jar and place the lid and ring or gasket on; which makes it self-seal. By doing this method, the soup will last in the fridge for at least a week. Normally, the potato soap will stay fresh 3-4days.
Can You Freeze Potato Soup?
Yes, you can freeze potato soup. It’s best to use the same day soup for freezing to ensure freshness. This really only works well without any type of dairy in it. If you use milk or cream, the milk will separate and the soup will be grainy. I use Ball freezer jars for freezing soup but I have seen others lay the soup flat in plastic storage bags to freeze then store like files.
