A boneless prime rib roast is the perfect romantic dinner because it’s just so dang easy! There’s not a lot of fuss involved with getting it on the table and, if you follow the directions, it comes out exactly right every single time. Once your romantic dinner is over you’ll have plenty left to add to your meal prep menus, too!

I always thought that prime rib was hard to make so I was totally shocked at how easy it was. I rubbed it down with my olive oil and herb mixture the night  before I was ready to cook it and that was all the preparation it needed. The flavor of the herbs soaked into the meat so that when it was cooked every single bit was juicy and full of flavor!

I really had only had prime rib roast at restaurants and on cruises prior to my making it myself. I figured it was too complicated for me. In my mind it was relegated to the same “don’t cook this at home, kids” shelf as whole lobster – which I will never ever cook because I can’t kill a live thing. Call me a wimp, call me a hypocrite but if I have to kill it or starve I’ll be starving, thanks.

I always hear about how great cruise ship fare is but I have to tell y’all, I’ve just gotten back from my fourth cruise and I’ve never been overly impressed with the food.

I mean, I’ve been on three major cruise lines and some are better than others but none of it has been anything that I’d go crazy over. By the last few days of vacation I can tell that it’s time to restock the kitchen. This cruise was a little different because I got sick so was on a diet of melba toast rounds and diet coke for the last three days.

All of that to say that prime rib roast is so easy to make there’s no real reason just to have it at restaurants — I promise. With Valentine’s Day on the horizon it’s a great possibility for a romantic dinner that keeps things nice and low carb.

About Boneless Prime Rib Roast

There always seems to be a lot of mystery surrounding prime rib roast, almost as if it’s one of those medieval dishes served only to kings. The truth is that, although it is an expensive cut, it’s so easy to make and so versatile there’s no reason not to have it as often as you like. Here are some prime facts about prime rib:

Where does prime rib come from?

Prime rib is a cut of beef that’s cut from the back of the upper rib section. It’s sometimes called a standing rib roast and is made up of seven ribs, which can be cut smaller or made boneless (as in this recipe).

What makes prime rib so good?

Prime rib has a large round or “eye” of meat in the center which is marbled with fat. The entire roast is also surrounded by fat. While the meat cooks the fat liquefies and adds flavor and juiciness to the meat. Also, since this comes from a part of the animal where the muscles are not used much it is extremely tender.

How long should I cook prime rib roast per pound?

If you follow the instructions here it will be a perfect medium rare but as a rule of thumb about 15 minutes per pound.

How long should I let the prime rib roast rest after cooking?

About 15 minutes is enough time for the meat to finish coming to the proper temperature and for the juices to settle into the roast.

What to Do with Prime Rib Roast Leftovers

If you create a cozy dinner for two with prime rib you’re going to have leftovers! No problem – I’ve got you:

  • Use the rarest portions in the center as prime rib another time. Since the center is often more rare than the ends it warms up well without overcooking. To use – thaw overnight in the refrigerator then add to a oven safe baking dish with 1/4 cup of beef broth. Cover with foil and heat in a 300F oven for 15 minutes.
  • If you have an electric meat slicer prime rib makes the best roast beef sandwiches ever.
  • Slice thinly and warm up with gravy to serve over cauliflower mash.
  • Use it for beef pozole verde.
  • Use it in place of chicken in this pot pie.
  • Cut it in chunks for stews.
  • Use it in wraps.
