This is actually a draft in progress, I’m posting as we go using an iPhone app. The following is the recipe we were going to use, but couldn’t find until too late. Updates to follow!
Prime Time for Revisiting Prime Rib of Beef
Unfortunately, despite our best efforts, it’s sometimes more like you cutting through a dry, overcooked roast while they stare daggers at you.
You can almost hear them thinking, “Way to screw up $80 worth of beef, jerk. I hope there’s lots of gravy.”
Well, hopefully this proven mathematical method will increase your chances for success significantly. This is a new video revisiting the same method I featured in this Prime Rib post a few years ago, which only used photos. There are lots of great comments on the original post, and if you’re skeptical, you should go check them out.
Here is the formula for what was called, “Method X.” The rib is brought to room temperature. Overnight is good, but at least 6 hours (this is CRITICAL)! Season anyway you like. Then multiply the exact weight times 5 minutes. For me it was 5.35 x 5 = 26.75 minutes, which we round up to 27.
The rib is cooked at 500 degrees F for exactly that many minutes. Then the oven is turned off. You wait 2 hours without opening the door. You then remove the prime rib and slice into the most perfectly medium-rare meat you’ve ever seen. By the way, I will be posting a short how-to for a quick au jus soon. Enjoy!
- To use this method you must have a full-sized, modern oven. It must have a digital temperature setting that indicates when it is preheated. Older ovens with manual controls can vary greatly, and the doors may not have the proper insulation.
- I’ve heard from lots of people that have used electric ovens and reported great results.
- This is a specific formula for achieving a perfectly pink prime rib cooked somewhere a shade under medium rare. I have no info on altering it for other degrees of doneness.
4 to 8 pound Prime Rib of Beef, bone-in, fat cap removed (ask the butcher to explain)
kosher salt as needed
1/4 cup soft butter
1 tablespoon freshly ground black pepper
1 teaspoon Herbes de Provence (this is just a dried herb blend – you can use any thing you like, or just salt and pepper)

What we ended up doing
We lathered it with butter, then “liberally” applied porterhouse and roast seasoning (“liberally” not necessarily meaning we borrowed the stuff with no intent to repay), then seared that sucker at 500F for 15 minutes. We then lowered the temp to 325F and are now watching the Cowboys lose while we drool.
More to follow.
Not yet, up to 140F. Another 30 minutes 😦
Checking under the hood.
We yanked it out of the oven, wrapped it in foil, and let it sit for 30 minutes while flailing about finishing everything else.
Good stuff. Cowboys lost, we ended up watching a Netflix streaming movie and enjoyed the evening.
Happy New Year, y’all!
