This recipe for Marinated Mushrooms is one that my husband Jack developed many years ago. At the time, Jack was managing food service for a private club in Boston that catered to politicians, military leaders and celebrities. Typically – for those high-profile guests – the menu was hand-picked for each visiting dignitary, and special staff was brought in to serve.
But when there was a break in dignitary and celebrity visits, the club turned back into a high-end private dining room with magnificent views of the Boston skyline and surrounding suburbs. For those dinners, Jack’s team served a standard menu that was developed and then approved by the president of the association that owned and managed the office building.
There was one item that the association president insisted on having available every day possible – these marinated mushrooms – and we’re sharing this delicious recipe with you today!
The mushrooms are lightly blanched in boiling water until tender, then drained and cooled. Then the mushrooms are marinated in a mixture of garlic, onions, herbs and spices, as well as Madeira wine, sherry, Dijon mustard, a touch of sugar and olive oil – all of which give these mushrooms a wonderful depth of flavor! These super flavorful marinated mushrooms should be chilled at least overnight before serving to ensure that the flavors are absorbed into the mushrooms, then served slightly chilled or at room temperature.
These marinated mushrooms are a fantastic side to a steak or other hearty meat and potatoes dinner – but they are also great served at a summer cookout!
