An onion sauce can refer to any sauce that contains onions and can be made in a variety of ways. Some versions may include caramelized onions, while others may be based on a roux or cream sauce. Onion sauce can be used as a condiment for meats, vegetables, or served as a dipping sauce. It can also be used as a base for other sauces, such as mushroom and onion sauce.
A luscious onion sauce, exuding a velvety texture, is artfully crafted by combining 1¼ cups of cooked and pureed onions with 1½ cups of Béchamel sauce and a generous addition of 2 tablespoons of cream. This delectable creation serves as a splendid accompaniment to a myriad of dishes, be it egg-based delicacies, vegetable preparations, or the timeless classic of cutlets.
