How to Make Diane Sauce
- Before cooking your sauce, cook your steak or protein of choice in the same pan over medium-high heat in 1 Tablespoon vegetable oil. Use a large, cast-iron skillet for best results. Remove and set aside the steak on a plate covered with foil. Do not clean the pan before step 2.
- Reduce the heat to medium and add butter. Once melted, add in sliced mushrooms and a pinch of salt and pepper. Sauté for 1-2 minutes, stirring frequently. Then, add in the garlic and onion to the skillet and sauté for another 2-3 minutes.
- Remove the saucepan from heat and add Cognac to the pan. Return pan to the heat once added - be careful as it may flare up! Sauté for 1-2 minutes to allow the alcohol to cook down. Then, add Dijon mustard, Worcestershire sauce, and beef broth, and stir well. Finally, add heavy whipping cream to the saucepan. Stir and allow it to cook for 5 minutes until the sauce thickens.
- Serve over your steak, and enjoy!
Sauce Diane Tips
- Want a little bit of a thicker sauce? Stir in a cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons water). Slowly pour into the bubbling sauce, stirring until desired thickness.
- Pairing this sauce with steak? Simply use the same pan you cooked the steaks in with the leftover oil, and make this while your steak rests.
- Want to substitute Cognac? Substitute for a quality brandy, or simply adding in a little extra Dijon mustard and Worcestershire sauce.
- We use cremini mushrooms in this recipe, but you can use any mushrooms you prefer, such as button, shiitake, or oyster mushrooms.
Can I substitute cognac for brandy in Diane Sauce?
Whether you use cognac or another type of brandy for the sauce doesn't really make much of a difference - however, I would recommend choosing a high-quality bottle of brandy.
And, add a little extra Dijon mustard and Worcestershire sauce for extra flavor if you are not using cognac.
Can I make Diane Sauce without alcohol?
If you don't want to use an alcohol-based ingredient I recommend using beef broth instead.
However, the Cognac used in Diane sauce adds a lot of flavor to the sauce, and most of the alcohol is cooked down and burns off during the cooking process, so I recommend using it if possible.
