Stephen Langlois is a Chicago area chef and author (with Margaret Guthrie) of Prairie: Cuisine from the Heartland (1991). As chef of Prairie restaurant in Chicago, Langlois was a pioneer in the local food movement.
Langlois was an innovative chef who defined American Midwestern cuisine in the 20th century. As chef of the now-closed Prairie from 1986 to 1997, Langlois showcased strictly Heartland regional fare, even steering clear of ocean fish. As Alice Waters delineated California cuisine, so Langlois highlighted foodstuffs of the Midwest, such as Iowa pheasant, Lake Superior whitefish and Sheboygan sausage.
