Ingredients (serves 2)
Steaks
-
Beef tenderloin steaks (or sirloin/ribeye) – 2 steaks, about 6 oz (170g) each, 1–1.5 inches thick
-
Salt and black pepper – to taste
-
Vegetable or canola oil – 1 tbsp (for searing)
Diane Sauce
-
Unsalted butter – 2 tbsp, divided
-
Shallot – 1 medium, finely minced (about 2 tbsp)
-
Garlic – 1 clove, minced
-
Cremini or white mushrooms – 4 oz (115g), thinly sliced
-
Brandy or Cognac – 1/4 cup (60ml)
-
Beef broth – 1/2 cup (120ml)
-
Worcestershire sauce – 2 tsp
-
Dijon mustard – 1 tsp
-
Heavy cream – 1/4 cup (60ml)
-
Fresh chives or parsley – 1 tbsp, chopped (for garnish)
Method
1. Prepare the steaks
Pat steaks completely dry with paper towels. Season generously on both sides with salt and pepper.
2. Sear the steaks
Heat oil in a large heavy skillet (cast iron or stainless steel) over medium-high heat until shimmering. Add steaks and cook:
-
For medium-rare: 2–3 minutes per side
-
For medium: 3–4 minutes per side
Transfer steaks to a plate and loosely tent with foil.
3. Make the sauce (do not wipe out the pan)
Reduce heat to medium. Add 1 tbsp butter to the pan. Sauté shallot and garlic for 30 seconds until fragrant. Add mushrooms and cook 2–3 minutes until golden brown and any liquid has evaporated.
4. Deglaze
Carefully pour in brandy – stand back as it may flare up. Stir, scraping up browned bits from the pan bottom. Let brandy reduce by half (about 30 seconds).
5. Finish the sauce
Add beef broth, Worcestershire sauce, and Dijon mustard. Simmer for 2–3 minutes until slightly thickened. Reduce heat to low, stir in heavy cream and remaining 1 tbsp butter until smooth. Taste and adjust salt/pepper.
6. Combine and serve
Return steaks and any accumulated juices to the pan. Spoon sauce over them and warm for 30 seconds. Serve immediately, garnished with fresh chives or parsley.

Pro tips
| Issue | Fix |
|---|---|
| Sauce tastes harsh or boozy | Cook the brandy down longer – it should smell sweet, not sharp |
| Sauce is too thin | Simmer an extra minute without cream, then add cream |
| Sauce is too thick | Splash in a little more broth or water |
| Steaks are overcooked | Use a meat thermometer (125°F/52°C for medium-rare, then carryover cooking to 130°F/54°C) |
Make it lighter
-
Skip the cream – finish sauce with an extra tbsp of cold butter off heat
-
Swap beef broth for bone broth and use Greek yogurt instead of cream (add at the very end without boiling)
