I don’t know why, but I’ve really been craving potato leek soup lately. I know, it’s a really strange craving to have, but I impulse bought a leek last week, and have been deciding what to do with it for days. I need a hobby. Anyway, this leek obsession got me thinking that I should probably try to make a low carb potato leek soup, and see if that satisfied the craving.
Good news, it did. I wanted to make this recipe fairly simple, because it kind of bums me out when I’m all excited to make something, and realize I don’t have a lot of the ingredients. So, this is a combo of some pantry staples, and a leek. I’m assuming you have a leek if you’re looking up how to make potato leek soup.
I’m so tempted to say that this soup is my favorite, but I feel like I say that about everything. Regardless, this soup is for sure in my top five. It’s creamy and filling, and it’s the perfect way to warm up on a chilly day. This is also pretty simple recipe to execute, so if you’re at beginner level – it’s for you!
Notes on Making Low Carb “Potato” Leek Soup
- To store: refrigerate in an airtight container for up to 4 days, or freeze up to a month.
- To reheat: Warm in a covered saucepan over medium-low heat, until the desired temperature is reached.
- Make It A Meal: Top with a serving of Tempeh Bacon and dairy-free “cheddar” – it’s like a baked potato, but in soup form!
- This recipe happens to be vegan because I’ve used coconut oil and coconut milk in lieu of butter and heavy cream. However, if you’d really like to use butter and heavy cream, go right ahead!
- This soup really doesn’t taste at all like coconut, for those of you who are worried.
- You’ve probably noticed a lack of salt in the ingredients. This is because vegetable stock is incredibly salty, and you might want to hold off on adding salt until you’ve reached the dinner table.
- I actually opted to use Better Than Bouillon in place of vegetable stock, because it’s more convenient and I don’t use stock enough to keep a thing of it around.
- An immersion blender will be your best friend with this recipe, but you can use a regular blender, so long as it’s heat-safe.
- If you don’t have Herbes de Provence, you could use a poultry seasoning blend, or your preferred seasoning blend (like this one from Bragg’s).
- You can also make your own Herbes de Provence blend by mixing up any of the following: thyme, rosemary, marjoram, oregano, savory, basil, fennel seed and lavender.

Low Carb “Potato” Leek Soup
- 1 medium leek
- 1 tbsp coconut oil or olive oil
- 2 -3 cloves garlic, minced
- 12 oz riced cauliflower 340g, or about 3 cups
- 2 1/2 cups of vegetable stock or broth 600ml
- 1/2 cup full fat coconut milk (120ml)
- 1 tsp herbs de Provence
- 1 bay leaf
- 1/4 tsp cracked pepper plus extra, for garnish
- 2 tbsp sliced chives for garnish
- Prep the leek by slicing off the leafy part and the root; quarter the remaining stalk lengthwise. Rinse off the leek (they're usually really sandy) and slice it crosswise.
- Heat the oil in a heavy soup pot or Dutch oven over medium heat. Add the leek and cook for about 5 minutes, until the leek has softened. Stir in the garlic and cook for another minute.
- Add the riced cauliflower, broth, coconut milk, herbes de Provence, bay leaf and pepper and stir to combine. Cover and cook another 20 minutes, stirring occasionally, until the cauliflower has completely softened.
- Remove the bay leaf and blend the soup with an immersion blender until smooth. Alternatively, carefully pour the soup into a blender and blend until smooth.
- Divide the soup among four bowls, and garnish with chives and pepper.
