HOW TO COOK PRIME RIB BONELESS ROAST RECIPES

Steps:

• For the prime rib: Preheat the oven to 500 degrees F. Put the butter, horseradish, peppercorns and 2 tablespoons salt in a medium bowl and stir until evenly combined. Slather the seasoned butter evenly over the top and sides of the roast (leave the bottom bare) and put on a rack set in a large roasting pan. Roast for 35 to 40 minutes (5 minutes per pound), then turn the oven off and let the roast sit inside the oven for 1 1/2 hours (do not open the oven door during this time). It should be dark golden brown on the outside and medium rare on the inside.
• For the sauce: Meanwhile, whisk the sour cream, horseradish, 2 teaspoons salt and 1 teaspoon pepper together in a medium bowl until well combined. Stir in the chives, cover and refrigerate until ready to serve. 
• Cut the roast into 1-inch-thick slices and serve with the sauce.

Steps:

• In small bowl, mix softened butter, garlic, thyme, salt and pepper. Set aside.
• Spray 6-quart slow cooker insert with cooking spray. Pour beef-flavored broth into slow cooker. Rub beef roast all over with vegetable oil. Heat 12-inch skillet over medium-high heat. Cook 4 minutes on ribs side, then turn and cook 1 to 3 minutes each on other sides, until browned, holding roast upright in skillet with tongs if necessary.
• Transfer to slow cooker, ribs side down. Rub butter mixture on top and sides of roast. Cover and cook on Low heat setting 3 to 5 hours or until desired temperature in center. For medium-rare, cook 3 hours 30 minutes to 4 hours, or until meat thermometer inserted in center reads 135°F. For medium, cook 4 hours 30 minutes to 5 hours, or until meat thermometer inserted in center reads 145°F. Transfer roast to cutting board. Cover roast loosely with foil; let stand 30 minutes before carving. Cut into slices.
• Meanwhile, stir together Creamy Horseradish Sauce ingredients. Serve with roast.
