Ingredients

For the Prime Rib

  • 6 lb. standing rib roast excess fat cap and bones removed with meat secured with kitchen twine - ask your butcher to do all this!
  • 6 whole peeled garlic cloves thinly sliced
  • 2 tablespoons salt
  • 2 tablespoons pepper

For the Au Jus

  • 4 cups beef bone broth
  • 1/2 cup red wine or red wine vinegar
  • 1 teaspoon fresh rosemary chopped
  • 1 teaspoon fresh thyme chopped
  • Salt to taste

Instructions

  • Remove the prime rib from the fridge about 3 hours before you plan on cooking it.
  • Liberally season the meat with salt and pepper on all sides and loosely wrap it back up in the butcher paper.
  • Let the prime rib sit on the counter and come to room temperature for at 3 hours.
  • Heat your oven to 350°F.
  • Make small slits in the prime rib and stuff each slit with a slice of garlic.
  • Place the prime rib on a roasting rack that is set inside of a roasting pan.
  • Roast the prime rib for about 2 hours or until the internal temperature reaches 130°F.
  • Remove the prime rib from the oven, transfer it to a large platter (keep all the drippings in the bottom of the pan), and tent it with foil to keep it warm.
  • Let the prime rib rest for at least 20 minutes while you make the au jus.
  • Using potholders, remove the rack from the roasting pan and position the pan over two stove burners set to high heat.
  • Add the red wine to the drippings in the pan and cook over high heat, scraping the bottom of the pan with a wooden spoon until the sauce is reduced.
  • Add in the beef bone broth and cook until it is reduced by half.
  • Whisk in the fresh rosemary and thyme and season the sauce with salt to taste.
  • Slice the rested prime rib to your desired thickness, plate, and pour the au jus over top.
