What Is Lobster Mornay Sauce?

Lobster Mornay Sauce is a luxurious concoction that elevates the already sumptuous lobster meat. It is a creamy and rich sauce made primarily from butter, flour, milk, and cheese, often gruyère or cheddar. 

The sauce is delicately seasoned, usually with a hint of nutmeg, and then combined with succulent lobster meat. The mixture is typically poured over lobster halves and broiled until golden. 

With this in mind, to get the most out of the recipe, you may want to use fresh lobster. This dish is often celebrated in upscale restaurants, making it a delightful treat for seafood enthusiasts.

While it’s uncertain who first thought to combine this creamy sauce with lobster, it was likely an innovative chef seeking to get the most out of luxurious ingredients.
