Low FODMAP mushrooms

  1. Oyster Mushrooms

Oyster mushrooms have a distinct oyster-like shape hence the name. They have a mild delicate flavour and a pleasant subtle aroma. Oyster mushrooms offer versatility in cooking, allowing them to be prepared in various ways such as stir-frying, grilling and roasting.

People commonly incorporate them into soups, stews, risottos, pasta dishes, and vegetarian/vegan recipes as meat substitute.

They are the only tested mushrooms that are low FODMAP in large quantities as they only become moderate in FODMAPs at a very large serving of 1kg!

  1. Canned Champignons Mushrooms

Canning reduces the FODMAP content of foods as the FODMAPs leech out in the canning liquid. 

Canned mushrooms are easy to find and have a long shelf life. However, their texture is quite different compared to fresh mushrooms. They tend to be softer and less firm. The flavour is also different however they do still retain some of the earthy and umami characteristics associated with mushrooms. 

They can be used in a variety of recipes including pasta dishes, stir fries, soups, stews, casseroles and as a pizza topping. 

When using these it is essential to drain and rinse them well. Limit your serving size to <200g.
