Sauce bordelaise is a classical French brown sauce associated with Bordeaux. A traditional version is built around red wine, shallots and a brown stock or demi-glace base, often with thyme and bay. Some classical formulations include bone marrow as a garnish or finishing element. Recipes differ, and the name should not be confused with every sauce containing Bordeaux wine.
Reduce a dry red wine with finely chopped shallots and aromatics such as thyme and bay. Add a well-made brown stock or demi-glace base and simmer gently to develop flavour and reach the desired consistency. Strain if a smooth sauce is required. Some versions are finished with small pieces of poached bone marrow, which add richness and a characteristic texture.
The sauce should be savoury and concentrated, with a recognisable red-wine character and enough acidity to balance its richness. It is classically served with grilled or roasted beef, including entrecôte and beef tenderloin. Garnishes and final consistency vary by recipe.
Example: serve sauce bordelaise with grilled entrecôte, pommes frites and a seasonal green vegetable.
Chef’s tip: use a sound, dry red wine that you would be comfortable serving. Reduce carefully; excessive reduction can make the sauce harsh, tannic or overly concentrated. Taste the brown sauce base before adding salt.
Related term: Sauce marchand de vin is another French red-wine sauce, often simpler and more directly based on wine reduction, shallots and stock. The exact distinction varies between classical references.
