ROAST BEEF RACK RECIPES

Steps:

• 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; sauté 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 425°F. 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 125°F for medium-rare (135°F to 140°F 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.
• Chateau Coufran 2003 (France, $23). The leathery, earthy notes and subtle fruit in this medium-bodied Bordeaux are perfect for the tenderloin.

Steps:

• Set up your sous vide water bath with the temperature set to 136℉
• In a small bowl, mix the minced rosemary and garlic with the smoked paprika, mustard and onion powders, salt, and pepper.
• Rub the beef down with Worcestershire sauce, then spread the spice rub over the whole roast.
• Vacuum seal the roast in a plastic bag and cook it at 136℉ for 24 hours. When the roast is done cooking, drain the liquid into a small bowl and set the roast aside for finishing.
• To get a nice crust on the outside of the beef roast, place it on a broiler pan and finish it in a 350ºF oven for 15 minutes, turning it halfway through. Once the roast comes out of the oven, let it rest for 5 to 10 minutes before serving.
• The juices from the roast can be served as an au jus. To make the au jus take the liquid from the bag the roast was cooked in and bring it to a boil in a small saucepan for three to five minutes.
• The au jus is especially good when you're using the roast beef to make French Dip sandwiches.
