National Oysters Rockefeller Day is celebrated every January 10, primarily in the United States. This holiday honors the rich seafood dish known as Oysters Rockefeller, which originated at Antoine's, a historic Creole restaurant in the French Quarter of New Orleans. The dish was created in 1899 by Jules Alciatore, who substituted local oysters for escargot and named it after John D. Rockefeller to signify its richness. The traditional preparation involves topping oysters on the half-shell with a green sauce made from butter, herbs, and vegetables, with parsley being a key ingredient. To celebrate, individuals can enjoy Oysters Rockefeller at local seafood restaurants, prepare the dish at home, or share their experiences on social media using the hashtags #NationalOystersRockefellerDay and #OystersRockefellerDay. The day was established by Antoine's in 2017 to commemorate this iconic dish.
