Ingredients

Cowboy Butter

  • 1 cup (2 sticks / 227 g) unsalted butter, softened
  • 2 tablespoons coarse Dijon Mustard
  • 2 tablespoons fresh chives, chopped
  • 2 tablespoons fresh parsley, chopped
  • 4 teaspoons fresh thyme
  • 4 teaspoons garlic, minced
  • 2 teaspoons lemon juice
  • 1 teaspoon paprika
  • ½ teaspoon kosher salt
  • ¼ teaspoon pepper
  • ¼ teaspoon cayenne pepper
  • ¼ teaspoon crushed red pepper flakes

Prime Rib

  • 1 boneless prime rib roast, 6-7 pounds

Instructions

Cowboy Butter

  • In a medium bowl, add the softened butter, dijon mustard, chives, parsley, thyme, garlic, lemon juice, paprika, salt, pepper, cayenne, and red pepper flakes. Mix together until combined. This recipe makes about 1 ⅓ cups of cowboy butter. (You could also mix the ingredients in a food processor.)
  • Reserve ⅓ cup of the cowboy butter for serving. The remaining butter will be used to season the prime rib.

Prime Rib

  • Remove the prime rib roast from the refrigerator and let it sit at room temperature for 2 hours to ensure even cooking.
  • If the roast is uneven in shape, use kitchen twine to tie it at 2-inch intervals to help it cook evenly.
  • Preheat the oven to 500°F. Position the oven rack in the lower third of the oven to fit the roast.
  • Place a roasting rack inside a large roasting pan. Set the roast on the rack.
  • Pat the roast dry with paper towels. Rub the roast generously with the cowboy butter.
  • Roast at 500°F for 15 minutes to develop a browned, flavorful crust.
  • Without opening the oven door, reduce the oven temperature to 325°F. Continue roasting for about 13 to 15 minutes per pound.
  • Start checking the internal temperature with a meat thermometer* 30-40 minutes before your estimated end time. The roast is ready when the thickest part reaches: 120°F to 125°F for medium rare; 130°F to 135°F for medium.
  • Once the desired temperature is reached, remove the roast from the oven.
  • Tent loosely with aluminum foil and let rest for 30 minutes. This allows the juices to redistribute.
  • Slice against the grain for the most tender bite and serve with the reserved cowboy butter, softened at room temperature or slightly melted.

Notes

*Since you are not opening the oven door, be sure to use a meat thermometer that has an external wire probe that allows you to see the temperature of the meat throughout the cooking process. These numbers I am giving you are just a guide; you should be checking the temperature regularly so the prime rib won’t be overcooked.
