One Pot Potato Soup Recipe
This hearty one pot potato soup recipe has a secret ingredient that gives it amazing taste! Part of the Sunday Supper series at On Sutton Place.
So…what’s the secret ingredient? The ingredient that gives this one pot potato soup recipe its amazing flavor is the addition of a leek. If you are like me, the first time I made this soup, I wasn’t sure what a leek was. It looks like a giant green onion, but has a very different taste. To prepare a leek, just chop off both ends and discard.
It’s a personal choice how much of the green part to include when you prepare the leek. You should have at least a 6-8 inch piece that includes both the green and white parts. A leek has a lot of layers, so wash it very well under running water. Slice it in half length-wise, then slice each half in half again. Finely chop the pieces and add it to your pot. If the layers sort of fall apart, just keep chopping. Once the leek is in the pot, it won’t matter.
The first several times I made this potato soup recipe, I used two pots…one for the soup, and one to make the roux. Recently, I discovered that it can be made all in one large pot, which makes clean-up so much easier! What follows is the one-pot method. Either way, this potato soup recipe is delicious!

One Pot Potato Soup Recipe Tips:
- It’s helpful to chop the vegetables, and measure out the other ingredients before assembling the soup. It makes the time spent at the stove much more pleasant!
- This one pot potato soup recipe could easily be adapted to a gluten-free dish. If you are on a gluten-free diet, but can tolerate dairy, simply substitute 1/4 cup of cornstarch for the 1/2 cup of flour.
- This soup can be stored in an airtight container in the refrigerator for up to 3 days. I recommend not freezing it. Dairy products and potatoes tend to get mushy and gritty when frozen.
- Any kind of potato can be used, but red or gold potatoes are recommended because they have a lower starch content, therefore they won’t add any extra thickness to your soup.
- If the soup gets too thick, simply add more milk or chicken stock. Taste and adjust the seasoning after thinning the soup.
- Tip from a reader: store cut up leek in an airtight container in the freezer for use in soups, salads, and pastas.
