Easy Prime Rib Roast

Rated as 4.64 out of 5 Stars

"I'm new to cooking, and I recently purchased a rib-eye roast, and had no idea what it was. I put a few ingredients together and cooked it and to my surprise, it was the best prime rib I've ever had. I thought I would share it with you. Hope you enjoy!"

  1. Mix garlic, rosemary, sage, thyme, salt, and pepper together in a small bowl. Pat garlic mixture over entire roast. Make an incision down the middle of the roast, keeping parallel with the bones. Place the roast in a plastic roasting bag and pour Worcestershire sauce and soy sauce into the bag, concentrating on the incision in the roast. Tie the bag and refrigerate roast to marinate, turning often, at least 2 hours.
  2. Remove roast from refrigerator and allow to come to room temperature, 1 to 2 hours. Remove roast from bag and discard marinade. Place roast, fat-side up, in a roasting pan.
  3. Preheat an oven to 500 degrees F (260 degrees C).
  4. Bake in the preheated oven for 15 minutes. Lower heat to 350 degrees F (175 degrees C) and continue cooking until an internal temperature of 145 degrees F (65 degrees C), about 1 hour. Let roast stand for 20 minutes before slicing.

Hands down m, AMAZING!! This was my very first attempt at prime rib. I love Prime rib and decided to try it for Easter. Like many of the other reviewers, I was nervous to be experimenting on ...

Turned out amazing! Had great flavor. Only thing I didn't use was rosemary. Took it out of the oven when the middle reached 125-130 degrees and let sit for 15.

Awesome! There were only 4 of us and I cooked a 2 1/2 pound roast. I cooked the roast for 15 minutes at 500 degrees and then reduced the oven to 325 degrees and cooked the roast for 30 minute...

Perfection. An absolutely must try rib roast. The rub makes the marinade delicious. My roast was 4.8 ounces and the timing worked out on the button. Thank you!

I went with a half cup of soya sauce on my 5lbs blade roast,marinade overnight,drained out the marinade ,3hours later, it turned out very well.

It was great

The prime rib was over cooked, which was a terrible thing to do with such an expensive cut of meat. But I did use the leftovers in beef and noodles they were awesome! I gave it a 4 star rating b...

I changed it up a bit. I did not use a cooking bag. I rubbed the roast with sea salt and ground black pepper, put it on a roasting pan. I preheated the oven to 500° and cooked the roast for 15 ...

This was a bit new to me, so I followed the directions. It wound up in the marinade a bit longer than 2 hours, yet all was fine. Our guests also enjoyed it. I'll do it again.
