What Is Steak Diane?

Steak Diane is a classic French-inspired steak dish, traditionally made with:

Beef tenderloin or filet mignon
A pan sauce featuring butter, shallots, Dijon mustard, Worcestershire sauce, cream, and cognac

The steak is quickly seared, then finished with a luxurious sauce that balances richness, tang, and depth. Historically, the dish was flambéed tableside, creating drama and enhancing the flavor of the sauce.

The History of Steak Diane

Despite its French name, Steak Diane gained popularity in mid-20th-century America and Britain, particularly in upscale restaurants and hotel dining rooms. It is believed to be named after Diana, the Roman goddess of the hunt, a fitting reference for a dish centered around premium cuts of beef.

In the 1940s–1960s, Steak Diane symbolized refined dining—served sizzling hot, often flambéed, and paired with classic sides like potatoes and green vegetables.

How to Make Steak Diane (Step-by-Step)

1. Prepare the Steak

Remove steaks from the refrigerator 20–30 minutes before cooking. Season generously with salt and freshly ground black pepper.

2. Sear the Steak

Heat a heavy skillet over medium-high heat. Add butter and a little oil. Sear steaks for 2–4 minutes per side, depending on thickness, until browned and cooked to your preferred doneness. Remove and keep warm.

3. Build the Sauce

Lower heat slightly. Add shallots and garlic to the same pan and sauté until fragrant and softened.

4. Deglaze with Cognac

Carefully add cognac or brandy, scraping up browned bits from the pan. Let it simmer for 30–60 seconds to cook off the alcohol.

5. Add Flavorings

Stir in Dijon mustard and Worcestershire sauce. Allow the mixture to reduce slightly.

6. Finish with Cream

Add heavy cream and simmer gently until the sauce thickens into a silky consistency.

7. Return the Steak

Place steaks back into the pan, spooning sauce over them. Cook briefly to warm through.

8. Garnish and Serve

Finish with chopped parsley and cracked black pepper. Serve immediately.
