SEARED BEEF TENDERLOIN FILET WITH BéARNAISE SAUCE RECIPE - (4.7/5)

Steps:

• PREHEAT oven to 425 degrees with a rack in the center. TRIM tenderloin and cut into 6-8oz filets; season each filet with salt and pepper. Heat an ovenproof sauté pan over medium high heat for 5 minutes. SEAR filets in oil on one side for 4-5 minutes. Turn them over, place the pan in the oven, and roast to desired doneness: (RARE SEAR 5 MINUTES, ROAST 5 MINUTES REST 5 MINUTES,) (MEDIUM RARE: SEAR 5 MINUTES, ROAST 7 MINUTES, REST 5 MINUTES) (MEDIUM: SEAR 5 MINUTES, ROAST 9 MINUTES, REST5 MINUTES). Remove pan from the oven, transfer filets to a plate, tent with foil and let rest 5 minutes before serving. SERVE with Béarnaise sauce. Béarnaise SAUCE: BRING vinegar, wine, shallots and tarragon to a boil in a small saucepan over medium high heat. Boil until most of the liquid evaporates , about 5 minutes. OFF heat, add water then whisk in egg yolks until frothy. GRADUALLY drizzle in butter, whisking constantly to incorporate. Sauce should be thick, but thin it with a little water if needed. If it is too thin, return it to low heat and whisk constantly until thickened. STRAIN sauce through a medium mesh strainer into a heatproof cup. Season with lemon juice, salt, white pepper, and cayenne. Serve immediately.
