Steak Diane with Demi-Glace Sauce

Follow our step-by-step guide on how to make Steak Diane with Demi-Glace Sauce.

1. Step 1

   Start by generously seasoning your steaks on both sides with salt, then let them rest at room temperature while you whip up a delicious sauce.

2. Step 2

   In a mixing bowl, combine demi-glace, Dijon mustard, Worcestershire sauce, tomato paste, and a pinch of cayenne pepper.

3. Step 3

   Stir until everything is well blended and set aside.

4. Step 4

   Next, heat a splash of oil in a skillet over high heat, making sure the surface is evenly coated.

5. Step 5

   When the oil starts to smoke, it’s time to add the steaks along with a few chunks of butter.

6. Step 6

   Sear the steaks for about 2 to 3 minutes on each side, aiming for that perfect rare finish with an internal temperature of 125°F (52°C).

   Once done, transfer the steaks to a warm plate to rest.

   Now, add shallots to the skillet and sauté for 2 to 3 minutes until they soften and become fragrant.

   Carefully remove the skillet from the heat and pour in some Cognac, igniting it with a lighter to burn off the alcohol—this adds a wonderful depth of flavor! Once the flames die down, return the skillet to high heat and bring the mixture to a boil, stirring occasionally to reduce it slightly.
