The Dish That Commands a Room
When Personal Chef Robert L. Gorman arrives at your Greenwich, CT residence — whether for a private dinner party in the backcountry, a holiday celebration in Riverside, or an intimate weeknight supper off Round Hill Road — he brings with him a repertoire shaped by four decades of fine dining mastery. Few dishes announce that mastery quite like Steak Diane with Courvoisier Demi-Glace: a sauce that flares blue at the pan, perfumes the room with cognac and shallots, and lands on the plate as something close to edible theater.
For discerning clients across Greenwich, Darien, and the broader Fairfield County corridor, this dish has become one of Chef Gorman's signature tableside experiences — requested especially for New Year's Eve dinners, Valentine's Day celebrations, anniversary evenings, and holiday cocktail parties where a warm, dramatic entrée sets the tone for an unforgettable night.
"The best personal chef isn't the one who shows up with the fanciest ingredients — it's the one who transforms your dining room into the best restaurant in Greenwich."
A History Written in Flame & Cognac
Steak Diane traces its origins to the mid-20th century golden age of tableside service, when New York's most celebrated supper clubs — the Colony, the Drake, and later the 21 Club — competed to dazzle guests with theatrical cooking. The dish takes its name from Diana, the Roman goddess of the hunt, a nod to its bold, game-ready flavors. By the late 1940s and through the 1950s, captains at elite Manhattan restaurants were pan-searing thin medallions of beef over gueridon carts, finishing them in a brandy-flamed sauce that drew gasps and applause from the dining room.
The sauce itself is a study in classical technique: whole butter emulsification, Worcestershire-darkened pan fond, Dijon mustard for bite, a splash of heavy cream, and — crucially — a reduction of rich veal or beef demi-glace that provides the dish's silken body. The use of Courvoisier VS cognac — the brandy famously associated with Napoleon Bonaparte — lends a distinctly French imperial character that distinguishes Chef Gorman's version from lesser interpretations. Courvoisier's Charentais profile, warm with dried fruit and toasted oak, integrates into the demi with uncommon depth.
The dish fell from fashion in the health-conscious 1980s but has enjoyed a spirited renaissance among private dining enthusiasts and upscale personal chef clientele — precisely the Greenwich and Fairfield County market where Chef Gorman has built his practice. Today, Steak Diane is less a restaurant dish than a personal chef's showcase: it demands skill, timing, and confidence, and it rewards a host who wants their table to feel truly exceptional.
Sourced Locally, Finished Classically
Chef Gorman's commitment to Fairfield County's finest local purveyors means Steak Diane begins long before the pan heats. For this recipe, he sources premium beef tenderloin from Saugatuck Provisions Butchery in Westport — a craft butcher whose dry-aged and hand-cut selections are unrivaled in the region. Fresh herbs, including thyme and chives, come from Gilbertie's Herb Farm in Westport, Connecticut's oldest and most storied herb grower, where varietal quality is grown, not sourced. For special occasions demanding the finest beef, Chef Gorman turns to the legendary Pat LaFrieda custom cuts or taps Sankow's Beaver Brook Farm in Lyme, CT for heritage-breed options.
When the season permits, a stop at the Greenwich Farmers Market (held Saturdays at the Arch Street Teen Center parking lot) yields extraordinary shallots, farm-fresh butter, and local mushrooms that elevate the sauce's aromatic base beyond anything found in a grocery aisle. The Westport Farmers Market, operating year-round on Imperial Avenue, is another essential stop for alliums, microgreens, and specialty produce.

Method
-
Sear the beef. Heat a heavy stainless or carbon steel skillet over high heat until barely smoking. Add grapeseed oil. Season medallions aggressively with salt and pepper directly before placing in pan. Sear 90 seconds per side for medium-rare. Transfer to a warm plate and tent loosely with foil. Do not clean the pan — the fond is essential.
-
Build the aromatic base. Reduce heat to medium-high. Add 1 tbsp butter to the hot pan. Once foaming, add shallots and cook 2 minutes, stirring frequently, until softened and beginning to turn golden. Add garlic and thyme leaves; cook 45 seconds until fragrant.
-
Deglaze with Worcestershire. Add Worcestershire sauce to the pan. It will sizzle violently — stir it into the fond, scraping up all browned bits. Cook 30 seconds.
-
Flambé with Courvoisier. Remove pan briefly from flame (critical for safety). Add Courvoisier. Return to heat and tilt pan or use a long match to ignite. Let the flame burn for 20–30 seconds, shaking the pan gently, until alcohol burns off and flames subside. The room will briefly fill with the aroma of warm cognac — this is the moment.
-
Finish the sauce. Add warm demi-glace and stir to combine. Bring to a gentle simmer; reduce 2 minutes to a glossy, nappant consistency. Stir in Dijon mustard and heavy cream. Simmer 1 more minute. Remove from heat and mount with remaining 2 tbsp cold butter, swirling constantly to emulsify. Taste and correct seasoning.
-
Return the beef. Nestle the rested medallions and any accumulated juices back into the sauce. Turn once to coat and warm through — 30 seconds maximum.
-
Plate and garnish. Spoon sauce generously over medallions. Scatter chives and parsley. Lay a fresh thyme sprig across the plate. Serve immediately alongside pommes Lyonnaise or crispy haricots verts.
