Sauce Chasseur, also known as "Hunter's Sauce," is a classic French sauce typically made from a base of demi-glace, which is a rich brown sauce. It is flavored with shallots, mushrooms, and often includes white wine or brandy. This sauce is commonly used to enhance the flavors of game meats, such as venison or pheasant, but can also complement other meats and poultry. The preparation of Sauce Chasseur involves sautéing the shallots and mushrooms, deglazing the pan with wine, and then adding the demi-glace. The sauce is usually finished with fresh herbs like tarragon or parsley, giving it a fragrant and earthy profile that pairs well with hearty dishes.
