How do you make Potato Leek Soup?
One of the easiest soups in the world to make is thankfully also the quickest. I sauté garlic and leeks in butter then add potatoes, a bay leaf, and broth, simmering until the potatoes are soft. Afterwards, I purée it until it’s smooth and I finish it off with some heavy cream to make this soup really irresistible.
What are the best potatoes for Potato Leek Soup?
For thick puréed soups, I like to use russets. If you like a chunky soup with a little more texture, use Yukon Golds, as they hold their shape better.
Can you freeze Potato Leek Soup?
This soup freezes fabulously; it’s great for stocking up on last-minute lunches and dinners when I don’t have time to cook.
Can you make Potato Leek Soup without dairy?
If you’re avoiding dairy, use olive oil for sautéing the leeks, and finish the soup with unsweetened nut milk in place of cream.

Should Potato Leek Soup be eaten hot or cold?
How you prefer to eat this soup is entirely up to you! Vichyssoise, a French potato leek soup, is traditionally eaten chilled. But because this recipe is made with chicken stock, I like to serve it piping hot, especially when it’s chilly outside.
Can you make Potato Leek Soup in a crockpot?
If you have a crockpot you’d like to use, place the leeks, butter, potatoes, bay leaves, and garlic in your crockpot. Season with salt and pepper to taste. Add the broth, just to cover the vegetables. Cover and cook on high for 4 hours, or low for 6 hours. Finish with the cream and chives.
How do you purée Potato Leek Soup?

- 3 cloves garlic minced
- 2 quarts chicken broth or vegetable broth
- 2 pounds potatoes cut into 1-inch cubes
- 1 bay leaf

To clean leeks:
