The last American on this list may be considered the best chef from the United States, but at No. 7, he is one of the best in the world. Dan Barber owns the Blue Hill in New York and Bill Hill at Stone Barns in the state’s Hudson Valley.

A leader in farm-to-table cuisine, Barber has received numerous James Beard Foundation awards and was appointed to the President’s Council on Physical Fitness, Sports and Nutrition by President Barack Obama.

Barber has worked to create new vegetables, including the honeynut squash, a breed of squash that is smaller with more intense flavor.
