Angels on horseback is a hot hors d'œuvre or savoury made of oysters wrapped with bacon. The dish, when served atop breads, can also be a canapé.
The dish is typically prepared by rolling shucked oysters in bacon and baking them in an oven. Modern variations of angels on horseback include skewering and frying. Serving can vary widely to taste on either skewers or breads, with additional accompaniments or condiments. Angels on horseback differ from the similar, fruit-based, devils on horseback, but the dishes' names are sometimes erroneously considered synonyms.
