How to Make 4 Ingredient Potato Soup 

A full printable version of this recipe with ingredient measurements is available at the bottom of this post.

STEP ONE: In a large Dutch oven or pot, heat some olive oil over medium-high heat. Add in your chopped onion and saute for 5 minutes, or until soft and slightly translucent.

STEP TWO: Add in your peeled and chopped potatoes and season a bit with some salt and pepper. Add the vegetable broth so that it covers the potatoes and bring everything to a boil.

Reduce the heat and cover. Let simmer over medium heat for about 20 minutes, or until you can pierce the potatoes with a fork. Remove the pot from heat and stir in your milk (or cream if you’re using it).

STEP FOUR: If you’d like, you can add in some additional ingredients such as butter, thyme, or garlic powder. Serve your soup with crumbled pieces of bacon, cheddar cheese, chopped green onions, or another garnish of your choice!

Do You Have to Add Flour to Potato Soup?

Many soups begin with a roux (a mixture of flour and butter). This helps to add extra creaminess and thicken the mixture. Because potatoes are naturally starchy, you don’t really need that extra step for my 4 ingredient potato soup!

The goal is to make an easy soup with few ingredients, so feel free to leave out the flour!

What is the Best Potato For Soup?

Waxy varieties are best for soups and stews. They’re also sometimes called boiling potatoes if you want to keep your eye out for that at the supermarket.

That said, the best potato for this old fashioned potato soup recipe is whatever you have on hand! Don’t feel obliged to run out to the store to pick up a specific kind.

How Do You Cut Potatoes for Potato Soup?

Be careful to chop your potatoes into evenly sized pieces for this easy potato soup recipe. If they are different sizes, they won’t cook evenly.  Ideally, you’ll want them to be in cube form about 1-inch in size.

What To Serve With Potato Soup?

As mentioned, you can serve my old fashioned potato soup with some bread and a salad. Here are some other yummy side dish ideas:

One of the best things about this easy soup with few ingredients is that you’ll have plenty of space in the kitchen to whip up something else to serve alongside it!

How Long Will Homemade Potato Soup Last in the Refrigerator?

You can place any leftover creamy potato soup in an airtight container in the fridge. It will keep for 3 to 4 days. 

You can freeze this soup, but be aware that the texture may be a bit different when you thaw it. If you do decide to freeze it, make sure that it has cooled completely before you do. It will keep in the freezer for up to 6 months.
