A definite different twist on an old classic. This prime rib will really spice things up! Use the pan drippings for au-jus or make some delicious Yorkshire Pudding. Whip up a batch of fresh horseradish sauce and serve this prime rib with garlic asparagus or a fluffy baked potato. Please note the total time includes 1 hour for marinating.

  • Cut ribs from roast, and place in a roasting pan. They will act as a roasting rack. Rub the meat all over with the soy sauce mixture. Then rub and coat with the Cajun seasoning mixture. Let marinate for at least one hour or wrap in plastic, and chill overnight.

  • Preheat the oven to 500 degrees F (260 degrees C).

  • Remove any plastic from roast, and place pan into the preheated oven. Roast uncovered for 15 minutes in the preheated oven. Pour water into the pan to produce moist heat. Reduce oven temperature to 300 degrees F (150 degrees C), and continue roasting for 1 hour and 10 minutes, or until the internal temperature is at least 130-140 degrees F/55-60 degrees C) for medium rare, or (145-155 degrees F/63-68 degrees C) for medium . Let the roast stand for 30 minutes before carving to let the juices return to the center.

Supurb flavor!! I used a 7 lb roast and added 2 Tbsp garlic powder to chili powder and blackened seasoning. Also, I added a cup of wine to the 2 cups of water in bottom of pan, which enhanced the flavor of the au jus. Will probably use chili powder with a little more "zip" next time for added spice (used mild this time). Final note: Pull your roast just before you think you should, then let it sit as recommended. Meat keeps cooking even after it's removed from oven, and you can always cook longer if it's too rare, but you can never uncook it. Overall, this is a must-try if you enjoy flavorful, delectible prime rib!! Read More

My family agreed that we really didn't taste any difference in the meat. To prepare this was time consuming and to no advantage. Sorry Bill but the 'old classic' is easier and faster for working mothers pressed for time. Read More

This is an excellent recipe but at what point do the seasonings become redundant? I mean 3/4 cup of chili powder? I added all the ingredients together and by the time I got too the soy sauce I'm wondering why do I need another 1/2 cup of chili powder. So I added the blackened seasoning to the bowl and added 1/3 cup of soy sauce instead of 1/4. Then I splashed enough water in it to desolve the sugar and wet the seasonings. I also did't separate the meat from the bone. I poured the mixture over the meat. It was very thick and clung nicely.I let it sit in the fridge for an hour then I cooked it as directed to 145 and was quite pleased with the result. I will definitly use it again and I will try it on pork spare ribs. Read More

I love the blackened taste but there's a fair bit of waste with the bones in this cut. I wonder if you could get more value for your money by using the same spice mixture with a boneless cut. Read More

this is one of my favorite meat entrees to make but a prime rib is often too expensive for my budget so I replace with a cheaper boneless cut like shoulder or butt most of the time. cooking time is about the same. it's less decadent but you get similar flavors. since it's cheaper I can stretch the meal a bit farther and have leftovers for roast beef sandwiches the next day!

I cooked this for my staff today for our Christmas "lunch". I was a little worried that it would be too spicy for some but everyone raved about the taste. Great recipe....won't be the last time I prepare prime rib this way! Read More

I dont make it this way every time but it has become our favorite and most requested for Christmas! I followed directions and the spices formed a crust which we peeled off before carving. Such a great flavor all the way through to the middle hardly anyone used Au Jeus spell or horseradish! You know its great when all you hear is MMMMMMMM Chewing and clancking silverware! Read one review that said it wasnt flavorful enough she must have really messed up because I have had Prime Rib from everywhere its my favorite and this is definately the most flavorable recipe I have had! It was hard the first time to put that much chili powder on a 150 roast but am I ever glad I did! I recomend following recipe exactly at least the first time chill overnight and remove from fridge 1 hour before cooking. Cook to your liking! ENJOY- 6 Stars Read More
