I was recently in St Petersburg Russia and had a great lunch at Tsar Restaurant (note: avoid bottled water, each one cost $25). I decided to try the Chicken Kiev, which was pretty common on the restaurant menus in St. Petersburg, and it seemed so “Russian” (though I later discovered that it’s not).
Chicken Kiev is actually French in origin. Russian aristocracy became very interested in French cuisine in the 1700s and they would send their Russian chefs to France to train or bring French chefs into Russia. A French chef called Nicolas Francois Appert invented Chicken Kiev in the early 1800s. Appert's invention became famous and Russian chefs tried to imitate Chicken Kiev, calling the dish "cotelettes de volaille" instead of Chicken Kiev.
Early restaurants in New York City changed the name back to Chicken Kiev, in an attempt to attract the new Russian immigrants and this name stuck. Traditionally, it is deep fried in oil, but I found a recipe from America’s Test Kitchen that achieves the same crisp coating with frying.
