About Mornay sauce

Mornay sauce is a French-style white sauce enriched with cheese, generally made by adding cheese to a béchamel base. It is smooth and creamy, usually pale in colour, with a mild dairy flavour and savoury cheese notes. Recipes vary in the cheese used and may include seasoning or other additions.

It is used as a sauce or topping in cooked dishes and is often baked until lightly browned. Mornay sauce may be prepared at home or sold ready-made, chilled, or shelf-stable. Thickness, richness, and flavour depend on the base sauce, cheese, and proportions, so the name does not define one fixed formulation.
