Frog legs (cuisses de grenouille)

Frog legs (cuisses de grenouille)

Frog legs are the muscular hind limbs of frogs, valued as a lean, delicately flavored meat with a texture often compared to chicken wings or tender whitefish. They are prepared in a wide range of regional styles from classical French to fiery Sichuan and Vietnamese stir-fries.

CategoryMeats
Scientific namePrimarily Lithobates catesbeianus (American bullfrog) and Pelophylax esculentus (European edible frog)
OriginGlobally consumed; culinary traditions strongest in France, China, Vietnam, Indonesia, Thailand, and the U.S. South

History & Origins

Frog legs have been consumed in China since at least the Han dynasty (206 BCE–220 CE) and were recorded as a delicacy in the Tang court. In Europe, French monks in the 12th century reportedly circumvented fasting rules by classifying frogs as fish; the dish gained international fame after the 19th-century banquet held in honor of President Benjamin Harrison by Black host and chef Thomas M. Clarke, when guests at the Glenview Country Club were served frog legs imported from France.
