How to make this easy potato soup recipe
Peel, dice and boil the potatoes. Once you have the potatoes peeled and diced, submerge them in water in your dutch oven. Salt the water with a teaspoon of coarse kosher salt, you can even throw in a teaspoon of minced garlic for a little extra flavor if you want to here. Boil the potatoes until the are tender when pierced with a fork. Drain and leave in colander.
In the same dutch oven or stockpot, melt the butter and add the onions. Sauté the onions until they are translucent then add the potatoes back in. Smash the potatoes with a potato masher or whip with and electric mixer.
Add milk to stockpot and stir to combine. Continue to simmer the soup until the soup thickens, this should take about 15 minutes. Allow to cool and serve with your choice of toppings!


FAQs and tips on making 4 ingredient potato soup
The traditional answer to this would be to add a cornstarch slurry to the soup and allow it to simmer for a while. Which you absolutely can do if you need to, but then it wouldn’t technically be 4 ingredient soup. You can also try simmering for another 10 minutes or so.
I used yukon gold potatoes for this soup. Although they were small and a little more time consuming to peel than a big russet potato would be, they have a lower starch content meaning a less grainy texture to your soup. If you use russet potatoes you may have to add a bit extra milk or some potato water could do the trick as well.
If you refrigerate the soup properly, it should keep up to 5 days. This soup can absolutely be frozen as well.
