Legends Steakhouse Prime Rib of Beef

Massage entire loin with Johnny Fleeman's Steak Marinade & Seasoning. You do this so the seasoning will stick to the meat.
With the fat side up (cooking side) sprinkle entire side with Ground Rosemary Seasoning (spice).
Sprinkle loin generously with Johnny Fleeman's Prime-Rib Seasoning.
Place loin in Browning Bag with seasoned side up; set on sheet pan or cake pan. Place in pre-heated oven at 250 degrees. Set timer for 2.5 hours. Ovens may vary. Check the prime-rib loin after the first hour for an internal temperature of 125 degrees. Keep cooking until an internal temperature of 125 degrees is reached for a rare to medium rare loin.
Use the beef drippings for a great Au Jus for dipping. You may have to add a little canned beef broth depending on the number of guest.
Slicing - try to keep the seasonings on the edges for great plate presentation.
