There’s Humungous Fungus Amongus, Ontario!

They may not be lookers (we’re talking about the more common types found in grocery stores), but sautéed in a little butter until golden brown, they transform into the most incredible umami-rich flavour bombs. Mushrooms are a powerhouse of nutrients, packed with vitamins, minerals and antioxidants. We should be eating more mushrooms!

Lucky for us, many farms in Ontario grow mushrooms year-round. From a crunchy spring salad to warm broths and soups in the fall, these versatile fungi can be used in all sorts of dishes, no matter the season.

There are three common varieties of mushrooms grown in Ontario: the ubiquitous white button, brown cremini and portobellos. A few farms also grow specialty mushrooms like oyster, shiitake, king oyster, and enoki. Grown inside warm humid rooms in large tiered trays of peat moss, cultivated mushrooms have a six-week growing cycle and are harvested by hand in stages or flushes.

Here are ten mushroom farms that grow and sell mushrooms to retailers, farm stands and restaurants across the province and beyond. When you pick up a pack of brown creminis from the grocery store, chances are they were grown on a farm in Ontario. So next time you’re perusing the produce aisle or eyeing a basket of fungi at the farmers’ market, keep an eye out for them!

Did You Know…

White button, cremini and portobello are in fact the same type of mushroom, Agaricus bisporus, but at different stages of growth?
The brown cremini is the older sibling of the white button, and portobellos are mature creminis that have been left to grow larger. But they do differ in taste. White button is the mildest tasting, followed by cremini mushrooms which are more flavourful. Since portobellos have more time to grow, they have less moisture than its younger counterpart. As a result, these mushrooms have a stronger, earthier flavour.
