A nice convection oven recipe to try !
* 4 portabella mushroom caps (5 in. wide)
Set mushroom caps, gill side up, in a single layer in a lightly oiled 10- by 15- inch pan. Bake in a 400° oven until caps are flexible enough to bend easily, about 12 minutes (about 9 minutes in a convection oven). The roasted portabellas is ready to serve !
