Sauce Diane is a creamy, savory sauce for steak made with mustard, Worcestershire, beef stock, cognac, Dijon and cream. It is a classic London recipe, dating back to the 1930s. While it is somewhat rarely served today, it is a delicious sauce, worthy of a position in any good chef’s culinary repertoire. I hope you try it, I’m sure you will love it!

More Information
Sauces and Gravies are Important
Sauces and Gravies are important in culinary arts because they add flavor that complements or contrasts with the foods they are served with. They can serve to moisten, add texture, and bind ingredients together. A good sauce or gravy is an almost necessary ingredient when creating the perfect bite.
About Sauces
There is a good discussion and summary of sauces in an article published on The Culinary Pro website, About Sauces.
When I was a child, when I grew up I wanted to become a sauce chef, or saucier. I was responsible for making Cajun Red Sauce, and Cajun Tartar Sauce, among other things. I loved this responsibility! Now that I’m much older, I admit that I have never formally worked as a saucier. But I still love making sauces! I’ll be adding this linked article to my research to help me decide which new sauces I want to make and publish here.
Choosing a Cognac
While the cognac does add flavor to Sauce Diane, its primary function is to deglaze the pan. Choose a cognac or brandy that tastes good, but don’t waste your money on VSOP or XO. It will quickly evaporate in the pan!
Pairings
Steak Diane tastes amazing with Garlic Mashed Potatoes and Bacon Wilted Spinach. Make sure to include some warm French Baguettes with Herbed Butter. The flavors in Steak Diane are bold, so pair with a hearty red wine, such as Cabernet Sauvignon.
