COOKING WHOLE BEEF TENDERLOIN RECIPES

Steps:

• In a large bowl, mix together oil, vinegar, mustard, thyme, sprigs of rosemary, bay leaf, smashed garlic, and honey. Add meat to bowl, cover with plastic wrap, and marinate in refrigerator for 1 hour or up to one day. Optional: Bring tenderloin up to room temperature before baking.
• Preheat oven to 450º. Line a rimmed baking sheet with aluminum foil and fit a wire rack inside. Remove tenderloin from marinade and pat dry with paper towels. Season all over with salt, pepper, rosemary, and minced garlic, then place on rack.
• Roast until cooked to your liking, about 20 minutes for rare. Let rest 5 to 10 minutes before slicing.
• Meanwhile, make sauce: In a medium bowl, whisk together yogurt, sour cream, horseradish, and lemon juice, and season with salt.
• Slice tenderloin and serve with sauce on the side.

Steps:

• Coarsely grind peppercorns and allspice together in a spice mill. Combine with salt in a small bowl. Sprinkle mixture evenly over exterior of roast. Add the grated garlic and rub in all over.
• Line a roasting pan with herb branches and set roast on top. Leave to absorb seasonings for at least 1 hour at room temperature, or refrigerate overnight (bring back to room temperature before proceeding). Heat oven to 400 degrees.
• In a large pot of well-salted boiling water, cook potatoes until just done, about 15 minutes. Remove with a spider or slotted spoon and place in an earthenware baking dish. In the same water, simmer parsnips until just done, about 8 minutes. Remove and add them to potatoes in baking dish. Pour melted butter over the potatoes and parsnips and use a brush to make sure they are well coated.
• Make the horseradish sauce: Whisk together crème fraîche, Dijon mustard, horseradish and cayenne in a small bowl. Season with salt and pepper and refrigerate.
• Roast the beef, uncovered, for about 1 hour. Check with an instant-read thermometer after 45 minutes. For medium-rare, take the roast out of the oven when thermometer registers 120 degrees (residual heat will cause roast to continue cooking as it rests). Remove the roast, tent it with foil, and let it rest for 15 minutes; the temperature should rise to 125 degrees. About 15 minutes after the roast goes into the oven, put in the baking dish of potatoes and parsnips, uncovered, and roast until beautifully golden brown, about 30 minutes.
• Slice the beef into 1/4-inch-thick pieces and arrange on a warmed platter, garnished with a big bunch of watercress. Pass the roasted vegetables and horseradish sauce separately.
