Can't find a low FODMAP vegetable stock? That's okay - I have a quick and simple recipe you can make in just 15 minutes (no cooking required). This stock concentrate freezes well and the salt helps give the concentrate a powder texture. This stock recipe doesn't contain a lot of salt compared to commercial stocks, so you may need to add an extra seasoning of salt and pepper to your meals as needed. So far my favourite use of this low FODMAP vegetable stock is in soup.
Note on celery & fennel: Both celery and fennel bulb can be high FODMAP in large serves. However, when mixed with water each cup of stock only contains 3.15g of fennel blub and 1.5g of celery, which is well within the safe low FODMAP serving sizes.
Make sure you buy a leek that has long green tips (this is the low FODMAP part), as you can’t use the white/light green leek bulb (this part is high FODMAP).
Choose processed products like sun-dried tomatoes, roasted red peppers, or olives that do not contain onion or garlic in the brine/oil.
