This gluten free potato leek soup recipe is perfect for a cold winter’s evening. It’s healthy, hearty, and easy to make.
Don’t you just love a hearty soup on cold nights? Winter has been pretty chilly this year in my college town, and this gluten-free potato leek soup recipe always lifts my spirits.
I have some dietary requirements, so I like being really clear about what’s in my food. I’m happy to say that this potato leek soup is:
- Gluten-free
- Soy free
- Grain-free
- Low FODMAP, if you moderate what parts of the leek you use and make lactose substitutions
- With substitutions: dairy-free
After a long day of freezing in college classes, I love coming home to a warm and hearty meal. I usually make this soup on the weekend and then eat it for a couple of weekday nights.
It can last for a while in the fridge. I’ve also put it in the freezer for a few months at a time, and it defrosts fine without losing flavor.
I’ve started keeping a few single-serving Tupperware containers of my potato leek soup in the freezer, just as a backup. It’s a great meal to have on hand if you come down with a cold. Another good meal for when you’re sick is gluten-free chicken soup.

Health benefits of the main ingredients
Disclaimer: Statements regarding health benefits are not intended to diagnose, treat, cure, or prevent any disease or health condition.
Leeks
Nourish by WebMD says that leeks are high in antioxidants that may have anti-diabetic, anti-inflammatory, and anticancer properties. They’re high in vitamin K, which helps with strong bones.
Potatoes
Potatoes are a starchy vegetable with lots of vitamin C and potassium. WebMD says that the skins are also high in fiber.
Cheese
Healthline says that dairy products, such as milk and cheese, are rich in calcium, vitamins A and B12, zinc, phosphorus, and riboflavin. Evidence suggests that dairy products can protect your teeth from cavities.
Tips for making this soup
This meal is very simple to make but needs a bit of time to simmer. Here are some of my suggestions:
- If you are low-FODMAP, use the green part of the leeks and substitute the butter and milk with vegan butter and coconut milk.
- If you don’t have a blending device, cut the leek into very small pieces.
- Coconut milk works well in this potato leek soup, but can make it taste more bland than with regular milk.
- Salt and pepper not long before serving and taste regularly so you don’t risk over-salting the soup.
- This potato leek soup goes great with grated cheese, chopped chives, and pan-fried chicken bacon.
- Other soups you may like: Classic chicken soup, or tofu, mushroom, and bok choy miso soup

Gluten Free Potato Leek Soup

Ingredients
- ½ large leek (bottom or top)
- 2 tablespoons butter (dairy free substitution: vegan butter)
- 4-5 medium potatoes
- 4 cups pre-made gluten free and low FODMAP chicken stock
- ½ cup milk (dairy free substitution: coconut milk)
- Salt and pepper to taste
- Optional: chicken-bacon, grated cheese, chopped chives
Instructions
- Finely chop the leek.
- Chop the potato into small cubes.
- Melt the butter in a pot over medium-high heat.
- Add the leeks and fry, stirring regularly, until fragrant and just beginning to brown.
- Add chicken stock to the pot.
- Add potatoes and bring to a simmer.
- Cook for 30-40 minutes.
- Blend the soup until smooth, either by adding it to a blender or by using a hand-held blending device.

Notes
If you are low-FODMAP, use the green part of the leek and substitute the butter and milk with vegan butter and coconut milk. If you do not have any sort of blender, cut the leeks as small as possible and mash the potatoes with a fork once they are cooked. Use less than ½ cup coconut milk if you substitute, as it can make the soup taste blander than regular milk.
