Are rib-eye steaks and prime rib the exact same beef, but simply cut, cooked, and served differently?

I wanted to make prime-rib at home for one or two people, but did not want to make a whole prime rib. It’s just too much food and I don’t want it to be leftover. Someone told me I could get a really big rib-eye steak and bake it at 400 for 20 minutes, then lower the heat to 200 until the meat was 120 F inside, and it would be pink and perfect just like a prime rib and that it was the same meat.

I have a hard time believing this but I don’t actually have any idea if it’s true or not.

Can anyone confirm or deny this for me?

Wow. Talk about fast response. Yahoo won’t let me pick an answer yet, and I’ll probably have to flip a coin w/ all these good ones, but I’m looking forward to french dip sandwiches, prime rib at home w/ horseradish and au jus, and also, hitting it with some cold mesquite smoke (far end of the smoker – small fire) for a touch of outdoor flavor. This is going to be wonderful. I love prime rib but didn’t know it was feasible to make a small amount at home for a reasonable price.

Ribeye and Prime Rib are from the same cut of meat… if you are wanting to do a small prime rib (boneless) then just ask butcher at most grocery stores to cut you a 2-3 lb boneless Prime Rib. Most will do it no problem,and they will usually tie up the roast as to not get mis shaped. Ribeye, although from the same loin, is usually cut from the fat cap end, meaning it is more marbled than what you may fine in a prime rib. That or just do a whole prime rib, use the left overs, for beef stew, stroganoff, endless options there:) Good luck,
