This low FODMAP mushroom crostini recipe is an Agur classic. My husband created it a few years ago and now it’s practically a holiday tradition. It’s definitely one of our favourites.

So how, exactly, is a recipe full of mushrooms low FODMAP? Magic! Just kidding. It’s actually science.

Did you know FODMAP molecules are water-soluble? This means they break apart in water. This recipe uses canned mushrooms (which have been packed in water), so some of their FODMAPs have leached out. Want to get nerdy with me? You can check out more information on the chemistry of FODMAPs here.

So what does this mean for you? According to a recent update from Monash University, small servings of canned mushrooms are low FODMAP. I’ve put more specific notes on portion sizes in the notes below.

Keep It FODMAP Friendly

These low FODMAP mushroom crostini will keep your taste buds and your tummy happy. Check out the notes below for tips on keeping this recipe FODMAP friendly.

First up is mushrooms. According to Monash University, canned mushrooms are safe in servings of 1/2 a cup (110 g) per sitting. Servings of 200 g or more are high in mannitol and should be avoided.

This recipe uses 1 can of mushrooms, which works out to 1 tbsp of mushrooms per crostini. This means you can have 4 mushroom crostini per sitting.

This recipe also uses two kinds of cheese: chèvre (goat) cheese and Asiago cheese. Both types of cheese are safe in servings of 1/2 a cup (60 g). But, we’re only using 2 tbsp of chèvre cheese and a sprinkle of Asiago for the entire recipe, so these won’t make a large contribution to your FODMAP load.

The final ingredient is your base. If you’re in the elimination phase, you need to use gluten-free bread or crackers. I used Glutino gluten-free bagel bites (original flavour).

I like using these for two reasons: 1) they’re a tiny bit salty which is nice with the deep earthy flavour of the mushrooms, and 2) they’re sturdier than crackers which means they won’t get soggy even if your guests aren’t quite on time.

Whose Side Are You On?

These low FODMAP mushroom crostini are awesome on their own, but if you’re using them for a large group or a holiday meal, you may need more options.

These crostini also work well with these low FODMAP garlic shrimp or my low fodmap caprese sticks. Both of these appetizers are also finger-friendly and relatively mess-free. Which is perfect for parties where people are moving around or standing.
