Oysters Rockefeller consists of oysters on the half-shell that have been topped with a rich sauce of butter, parsley and other green herbs, and bread crumbs, then baked or broiled. Lemon wedges are the typical garnish. The original sauce may or may not include spinach, a popular shortcut for achieving the dish’s signature green color.
Reportedly first made at Antoine’s Restaurant in New Orleans, Louisiana.
Rockefeller oysters are known for their distinctive green color. The rich green hue is reminiscent of money, leading to the dish’s name in honor of the wealthy John D. Rockefeller.
