Steak in Red Wine Sauce

Seared filet mignon finished with a glossy red wine pan sauce is French bistro cooking stripped to its essentials. The steaks get a hard sear for a dark crust, then rest in a warm oven while shallots and garlic soften in butter in the same pan.

The sauce comes together by deglazing with dry red wine and beef stock, then reducing by half until it coats the back of a spoon. That reduction concentrates the wine’s tannins and fruit into an intense, silky sauce that clings to each slice of steak. A pinch of thyme adds an herbal note without competing with the wine.

Searing over high heat for just one minute per side before reducing to medium-high locks in a crust without overcooking the center. Filet mignon is a lean, tender cut that dries out quickly, so restraint with the heat is everything.

Chef Tips

• Let the steaks come to room temperature for 20 minutes before cooking. Cold meat from the fridge sears unevenly and stays rare in the center while the outside overcooks.
• Pour off the grease before making the sauce. The rendered fat from searing would make the wine sauce greasy instead of clean.
• Use a wine you’d actually drink. Cooking concentrates the flavor, so a bad wine makes a bad sauce.

Variations

• Swap beef stock for veal stock if you can find it. Veal stock has more body and creates a silkier, richer sauce.
• Add a tablespoon of Dijon mustard to the finished sauce for a sharper, more peppery bite.
• Stir in a splash of heavy cream at the end for a Bordelaise-style creamy wine sauce.
