"This is a great meal with a crispy crust. The heat of the oven removes a bit of the bite of the hot sauce. Enjoy!"

  1. Preheat an oven to 500 degrees F (260 degrees C).
  2. Place the prime rib into a roasting pan, and rub all over the outside with the hot pepper sauce. Evenly sprinkle with garlic powder and Cajun seasoning.
  3. Roast, uncovered, in the preheated oven for 20 minutes, then reduce heat to 350 degrees F (175 degrees C), and continue roasting to your desired degree of doneness, or an internal temperature of 145 degrees F (65 degrees C) for medium, about 2 hours. Remove from the oven, cover with a doubled sheet of aluminum foil, and allow to rest in a warm area 30 minutes before slicing.
  4. While the roast is resting, scrape the drippings from the roasting pan into a skillet. Place the skillet over medium heat, and stir in the sliced mushrooms. Cook and stir until the mushrooms have softened and begun to release their liquid. Serve alongside the sliced prime rib.

this was absolutely delicious. I made it as directed and it could not have been more perfect. I posted a pic on fb.

I purchased a boneless prime rib with the plan to use my new electric slicer. I cooked the prime rib as directed, watched the internal temperature, let it rest, and then sliced. It was better ...

absolutely awesome. did mine in convection oven and heating time is right on. with convection knock time down to 1.5 hrs and and shorten searing time by five minutes

I give this recipe 5 stars with adding extra cajun seasoning. It gives the roast a wonderful crust! This has become our favorite!

Adding the Tony Chachere's seasoning really made the meat delicious! I have a huge shaker of the stuff that my mom gave me and I have never found another recipe that used it. Thanks!

Wish I could give you a hug right now. Best recipe I have made on this site to date....Thank you for posting. 120 degrees makes a perfect medium rare.....other than the internal temp I followed ...
