How to make Potato Leek Soup with White Cheddar:
Recipe Ingredients (In Addition to Leeks and Potatoes):
- Leeks: Leeks are alliums so they’re related to garlic, chives, shallots, and onions. They have a sweet, oniony flavor but unlike their relatives, they are best cooked rather than consumed raw. Leeks can also be very muddy so thorough washing is necessary. See below for how to do that.
- Russet Potatoes: I prefer Russet potatoes in this Potato Leek Soup for their starch content but you can also use waxy potatoes such as red or Yukon golds.
- Chicken Broth: When I don't make my own chicken stock / broth, I use Swanson Natural Goodness.
- White Cheddar Cheese: White cheddar cheese does not have any color added. May also use yellow cheddar cheese.
- Gather and prep all the ingredients.
- Start with the leeks. Leeks can be very muddy, so after halving and slicing the leeks, immerse them in a bowl of cold water.
- Swish the leeks around so any dirt that is trapped in the layers falls to the bottom of the bowl.
- Then scoop the leeks out with your hands or a slotted spoon, leaving any debris behind.
- Peel and cube the potatoes. I don't do this too far ahead of time because they can discolor unless you keep them immersed in water. There's no problem if you do that, just keep in mind they will discolor if not covered with water.
- Cook the leeks in a large pot until they're melty soft in the butter and oil. Stir them often and be careful to not brown or burn the edges.
- Add the garlic and cook briefly.
- Add the peeled and cubed potatoes, chopped fresh thyme and chicken broth.
- Bring to a boil, reduce the heat then simmer until the potatoes are tender.
- Add the cream and cheese.
- Puree using an immersion blender until the soup is silky smooth! If you don't have an immersion blender, grab one below in the affiliate links! You'll be glad you did!
- Season to taste with salt and pepper.
- Garnish with fresh chives and crispy bacon if desired!
- Total creamy, cheesy comfort in a bowl!
Chef Tips and Tricks:
- When a recipe requires softly cooked onions, leeks and shallots, I start with cooking them in fat, but will then add small amounts of water to help move the softening process along. This keeps them from getting brown, golden or burning because these vegetables have a lot of sugar in them.
- Immersion blenders are one of the most useful kitchen appliances you'll ever own. Besides pureeing soups, they're great for many things including smoothing out lumpy gravy or sauce.
Frequently Asked Questions:
Yes, it's possible to freeze potato leek soup. Thoroughly cool the soup then place in containers as desired. Freeze for 2 to 3 months. Thaw in the refrigerator then gently reheat over low heat. Whisk the soup several times while heating to bring it back together and smooth it out.
Absolutely! You can make Potato Leek Soup 2 to 3 days ahead of time. Cool thoroughly then refrigerate. Reheat on the stovetop on low heat until heated through.

It’s on the stove right now! This is my second time making this it is so good. I was short 2 cups of chicken broth but had vegetable broth. Hope it doesn’t change the taste too much. This is now my go-to potato soup!
Hi, Gail and thanks so much! I think the vegetable broth will be just fine--may change the color a bit. So glad you're enjoying! Thanks again!
I made this as is with the substitution of rosemary salt for plain salt just because I really like rosemary and potatoes together. Rave reviews all around! One of our guests said it was the best potato soup he'd ever eaten.
Hi, Barb and THANKS so very much! Love the idea of the rosemary salt; rosemary is definitely great with potatoes. Glad everyone enjoyed and thanks again so much!
