À la Béarnaise is a French cooking term that means “in the style of Béarn.”
Béarn is the former name for a region in the Pyrenees mountains of France. Now the area is roughly occupied by the département of Pyrénées-Atlantiques.
The term usually means with Béarnaise sauce but it can also mean something prepared in the cooking style of the region of Béarn.
This can mean with ham from the area, such as jambon de Bayonne, or with tarragon, capers or a splash of vinegar.
