The sauce, rich and velvety, incorporates the textures of shallots and garlic. Its flavor profile is intricate, featuring Worcestershire sauce, flambéed cognac, mustard, and onions.

What Is Steak Diane?
Steak Diane typically refers to a pan-seared steak dish cooked in butter and finished with a flambéed cream and cognac sauce. While some recipes use strip steaks, we prefer tender beef filets or beef tenderloin medallions. Mushroom additions vary, with some recipes including them and others omitting.

The name “Diane” pertains to the pan sauce, crafted with mustard, cream, Worcestershire, and flambéed cognac.

Basting the steaks in butter ensures a flavorful, beefy saltiness that harmonizes beautifully with the cognac-infused sauce. Flambéing is a quick, safe process; however, without proper ventilation, omit this step or allow the alcohol to cook off over low heat.
