BONELESS BEEF RIB ROAST RECIPES

Steps:

• Preheat the oven to 450°. In a small bowl, mix the mustard with the garlic, thyme, pepper and 2 teaspoons of kosher salt. Whisk in the olive oil.
• Set the meat, bone side down, in a roasting pan and season it lightly with salt. Roast the meat in the lower third of the oven for 20 minutes.
• Remove the meat from the oven and reduce the temperature to 350°. Brush the mustard coating all over the top and sides of the meat and roast for about 1 1/2 hours longer, rotating the roasting pan 2 or 3 times for even browning. The meat is done when an instant-read thermometer inserted in the center of the roast at the thickest part registers 120° (for medium rare). Transfer the roast to a carving board, cover it loosely with foil and let rest for 20 to 30 minutes.
• Set the roast on its side and run a long, sharp knife between the bones and meat; remove the bones and set them aside. Turn the roast right side up. Carve the roast 1/4 to 1/2 inch thick and transfer the slices to warmed plates. Pour any carving juices over the meat and serve at once. For bone-gnawing carnivores, cut down between the rib bones and pass them on a plate.

Steps:

• Season roast all over with 2 Tbsp. steak seasoning. Transfer to a wire rack set inside a rimmed baking sheet and let sit at room temperature 1 hour.
• Preheat oven to 225°F. Roast beef until an instant-read thermometer inserted into the center registers 120°F, 3 1/2–4 hours (start checking every 5–10 minutes after 3 1/2 hours). Tent with foil and let sit at least 30 minutes and up to 1 hour. Increase oven temperature to 500°F.
• Meanwhile, whisk sour cream, horseradish, pepper, salt, and 1/4 cup mustard in a small bowl; set aside.
• Remove string from roast; discard. Stir butter and remaining 1/4 cup mustard in another small bowl. Using a pastry brush, thickly coat roast with mustard-butter sauce. Coat with remaining 2 Tbsp. steak seasoning. Roast beef until a brown crust forms, 5-10 minutes. Transfer to a cutting board and carve. Serve with sour cream sauce alongside.
• Sour cream sauce can be made 1 day ahead. Transfer to an airtight container and chill.
