Literally the 'filet mignon' of beef roasts, this is a fantastic dish for a formal or holiday meal.
Sprinkle entire surface of beef tenderloin with coarse kosher salt. Place beef on rack set over large rimmed baking sheet. Refrigerate uncovered at least 24 hours and up to 36 hours.
Melt 2 tablespoons butter in large saucepan over medium-low heat. Add shallots; saute until soft, 3 minutes. Add Cognac, rosemary, and 1 teaspoon cracked pepper and cook until liquid evaporates, 1 minute. Add Port; bring to simmer. Add all of beef stock. Boil until reduced to 1 1/2 cups, about 20 minutes. Strain into medium saucepan, pressing on solids to extract as much liquid as possible. Discard solids in strainer. DO AHEAD: Can be made 24 to 36 hours ahead. Cool slightly, then cover and chill.
Let beef stand at room temperature 1 hour before roasting. Position rack in center of oven and preheat to 425F. Rub beef all over with oil; sprinkle with 2 tablespoons cracked peppercorns, pressing to adhere. Return beef to rack on baking sheet and roast until instant-read thermometer inserted into thickest part of meat registers 125F for medium-rare (135F to 140F in thinnest part), about 30 minutes. Remove roast from oven and let rest 15 minutes.
Bring sauce to boil; whisk in remaining 2 tablespoons butter. Season sauce to taste with salt and pepper.
Cut off string from roast. Cut roast crosswise into 1/2-inch-thick slices; arrange on platter. Serve with sauce.
TEST-KITCHEN TIP: Salting in advance, also called dry brining, is often done to improve the texture of sinewy cuts of meat. But it also works magic on tender cuts, amping up flavor and juiciness. It sounds counterintuitive; for years the accepted wisdom was that pre-salting dries out meat. But the moderate salting you'll be doing here does the opposite. Water is first drawn out of the meat and then gets reabsorbed; this saltier, more flavorful moisture helps intensify taste. What's more, the exterior of the tenderloin dries out slightly, making it quicker to brown in the oven.
WHAT TO DRINK: Chateau Coufran 2003 (France, $23). The leathery, earthy notes and subtle fruit in this medium-bodied Bordeaux are perfect for the tenderloin.
My Notes: First made 11/18/07. Had to sub a burgandy cooking wine as it was Sunday and the package stores were closed. Seared over a hot oak/lump fire and then cooked indirect heat (400f) for a little over an hour until it registered 130f on the probe thermometer. Tender, delicious, excellent. Used some of the sauce to finish off some sauted 'baby bella' mushrooms. The sauce was a great dipping sauce, full of flavor, but to use as a true sauce, reduce it more next time. Also, the beef stock recipe yields 3 cups so you can substitute 3 cups of beef broth.

Kathies52 4y agoFantastic done for dinner party last night for friends, so easy the fillet was superb would use recipe again and again and ag......
Cucinak 4y agoMade roast for the first time ever, on christmas and it turned out delicious. I didn't have port,so used marsala wine, and it seemed to work well. Also, didn't brine meat a day ahead. Instead, rubbed Omaha steak house marinade on it the morning I baked it, and let it set out at room temp for an hour or longer before searing it at 500 degrees. Yummy!
Joan32578 5y agoDry brine is great! Used on a round eye roast with excellent results
Clau03 5y agothanks for the recipe I learn the advance salted technic to make moist tender roast
chefhoward76 5y agoWe really enjoyed this wonderful recipe. Our family doesn't care for Port so I substituted a favorite red wine instead. The roast was easy to prepare and had great flavor. I recommend serving it on the rare to medium-rare side.
wcalleya 6y agoOne of my favorite dish....
Jeavou 6y agothe meat was great...the sauce didn't work out for me, it tasted good...but was just really not what it was supposed to be I think. The meat, dry brined, will be my new way to roast.
