Madeira sauce is a savory French sauce defined as a demi-glace sauce with the addition of Madeira wine. The sauce is made by sautéeing shallots on butter, then adding bouquet garni and Madeira wine until the concoction is reduced. After that, demi-glace is added to the combination, which is whisked until everything is blended together.

This sauce is an ideal choice for red meat, chicken, steaks, and roasts, but it's most often used as an accompaniment to beef Wellington.
