This is a "comfort food" for any season, baked until golden brown and bubbling. Lovely as a side dish with any roast meats or vegetable dish.
The low FODMAP diet is not dairy-free but is lowered in lactose. This recipe uses lactose-free half and half milk which you can either buy or make your own.
Note: Monash University has lab tested oyster mushrooms and determined them to be low FODMAP in incredibly generous portions of 75 g per person, which is about 1 cup.
