A French sauce spoon or saucier spoon is a spoon that is typically the size and shape of a dessert spoon, but with a flattened bowl that has a thinner edge and a small notch on one side. As the name suggests, a French sauce spoon is used to eat the sauce accompanying a dish. The spoon's flattened bowl and thin edge aids scooping a thin layer of sauce from a plate without resorting to tipping the plate; the notch in the bowl allows oil or fat to drain away from the sauce.
Originally found mainly in France, French sauce spoons are becoming increasingly popular in high-end restaurants elsewhere.
French sauce spoons are sometimes referred to simply as "sauce spoons," but note that that term can also be used to refer to a spoon used to serve sauce.
