Low FODMAP Leek and Potato Soup

January 14, 2019 by Amy

Looking for a simple lunch idea? With a rich, hearty flavour, this low FODMAP leek and potato soup will keep you warm all winter long!

Heads up, this post uses affiliate links. If you make a purchase using one of the links I’ve provided, I’ll receive a small sum of money. You can read more about my affiliations here.

Somehow every summer I forget how much I love soup. Maybe it gets too hot here in Canada, or maybe I’d rather eat my potatoes as french fries in the summer? I’m not sure. But, every winter, I curl up with a warm bowl of soup and I fall in love all over again.

This leek and potato soup is an old favourite of mine. I made a few easy FODMAP-swaps so you can enjoy it too! Let me know what other kinds of soups you like in the comments and I’ll see what I can do to put your favourite soup back on the menu!

Think this low FODMAP leek and potato soup sounds great, but you don’t have time to try it now? Don’t worry! You can PIN THIS POST for later.

Keep It FODMAP Friendly

This low FODMAP leek and potato soup is the perfect sidekick for a cold winter day! Check out the notes below for tips on keeping this recipe FODMAP friendly.

First up, leeks. According to Monash University, the green part of a leek is low FODMAP in servings of 2/3 of a cup per sitting. Servings of 1 cup or more are high in the polyol mannitol, so measure carefully.

This recipe uses 1 cup of leeks total, which works out to 1/4 cup per person. This is well within Monash’s recommended range.

Next up, potatoes. According to the Monash app, potatoes don’t contain any FODMAPs. That means you can eat as many as you want without adding to your FODMAP load. Woohoo!

We’ll also be using vegetable broth. I haven’t found a low FODMAP vegetable broth at my local store, yet. So I normally either make my own or use this low FODMAP vegetable soup base from Fody Foods Co.

Last but not least, dairy products. This recipe uses both butter and whole milk. If you’re in the elimination phase of the Low FODMAP Diet, you need to use lactose-free products. For my Canadian peeps, both Nielson and Lactantia have lactose-free lines that go up to 35%.

So, do you need to use lactose-free butter, then? Nope! According to the Monash app, butter doesn’t have any FODMAPs (because it’s all fat). Just double-check the ingredients for “milk solids” and you’re good to go!

FODMAP math

You are what you eat! Check out the notes below to see how many servings of each FODMAP group are in 1 cup of this recipe.

Fructose = 0
Lactose = 0
Fructan = 0
GOS = 0
Polyol = 0.3
