Sauce Bigarade is a classic French sauce which features the flavour of bitter orange. It is one of the few French sauces which can be classed as sweet and sour. Often called orange sauce, bigarade sauce was originally made with "bigarades," the Provençal name for bitter oranges.

This is a sweet-and-sour sauce usually used to accompany roast or pan-fried duck. The sharpness of the bitter orange cuts through both the sweetness of the sauce, and any fatty taste of the meat it is served with.

Classically, the sauce is based on a gastrique (carmelized sugar mixed with wine vinegar) to which is added veal stock or demi-glace sauce, along with the juice and blanched rind of bitter Seville oranges.
