Steak Diane is a timeless classic that brings the elegance of mid-century fine dining into the modern kitchen. This dish features tender, pan-seared steak medallions served with a luxurious sauce made from cognac, Dijon mustard, cream, and mushrooms. The sauce is flambéed for depth and drama, creating a rich, velvety coating that perfectly complements the beef.
Once a staple of upscale restaurants and tableside service, Steak Diane remains a symbol of sophistication and indulgence. It’s a dish that feels extravagant yet approachable, perfect for romantic dinners, celebrations, or when a touch of old-world charm is desired.
The Essence of Steak Diane
The essence of Steak Diane lies in its balance of flavors — the savory richness of the beef, the tang of Dijon mustard, the sweetness of cognac, and the creaminess of the sauce. The dish is traditionally prepared tableside, where the sauce is flambéed for a touch of theater. The result is a meal that’s both visually stunning and deeply satisfying.
It’s a dish that captures the glamour of classic dining while remaining simple enough to prepare at home.
Why This Recipe Works
This recipe works because it layers flavors through searing, deglazing, and reduction. The steak is seared to develop a caramelized crust, then removed while the pan is used to build the sauce. The cognac deglazes the pan, lifting the flavorful browned bits, while the cream and mustard create a smooth, rich finish.
The result is a perfectly cooked steak coated in a sauce that’s bold, balanced, and irresistibly silky.
Ingredients and Their Roles
Steak medallions (beef tenderloin or sirloin): The main protein, tender and flavorful.
Salt and black pepper: Essential for seasoning.
Butter and olive oil: Used for searing and adding richness.
Shallots and garlic: Add aromatic depth.
Mushrooms: Provide earthiness and texture.
Cognac or brandy: Deglazes the pan and adds complexity.
Dijon mustard: Adds tang and sharpness.
Worcestershire sauce: Enhances umami flavor.
Heavy cream: Creates a smooth, velvety sauce.
Fresh parsley: Adds color and freshness.
Step-by-Step Recipe
Ingredients
- 2 beef tenderloin steaks (about 6 ounces each)
- Salt and freshly ground black pepper, to taste
- 1 tablespoon olive oil
- 2 tablespoons butter, divided
- 1 shallot, finely chopped
- 1 cup sliced mushrooms
- 1 clove garlic, minced
- ¼ cup cognac or brandy
- 1 teaspoon Dijon mustard
- 1 teaspoon Worcestershire sauce
- ½ cup heavy cream
- 1 tablespoon chopped fresh parsley
Preparation
- Prepare the steaks. Pat the steaks dry with paper towels and season both sides with salt and pepper.
- Sear the steaks. Heat olive oil and 1 tablespoon butter in a large skillet over medium-high heat. Add the steaks and sear for 3–4 minutes per side for medium-rare, or until the internal temperature reaches 130°F (54°C). Transfer to a plate and cover loosely with foil.
- Sauté the aromatics. In the same skillet, add the remaining butter. Add shallots and mushrooms, cooking for 3–4 minutes until softened and golden. Add garlic and cook for 30 seconds until fragrant.
- Deglaze with cognac. Carefully add the cognac or brandy to the pan. If desired, flambé by tilting the pan slightly to ignite the alcohol (optional). Let the flames subside naturally.
- Build the sauce. Stir in Dijon mustard and Worcestershire sauce, scraping up any browned bits from the bottom of the pan. Add the cream and simmer for 2–3 minutes until the sauce thickens slightly.
- Return the steaks. Place the steaks back into the pan, spooning the sauce over them. Simmer for 1–2 minutes to warm through.
- Serve. Garnish with chopped parsley and serve immediately with the sauce spooned over the top.
Tips for Perfect Steak Diane
- Use tender cuts like filet mignon or sirloin for the best texture.
- Don’t overcook the steak; medium-rare is ideal for tenderness.
- Deglaze carefully if flambéing — keep a lid nearby for safety.
- Let the sauce reduce gently for a smooth, creamy texture.
- Serve immediately for the best flavor and presentation.
