Prime Rib is my favorite thing on our Christmas table. F-A-V-O-R-I-T-E. You know, just enunciating it out for you so that you know how sincere I am in that statement. 😉

I have prepared it many different ways, and two of those ways I’ve already showcased on the blog. They are all absolutely delicious and which one you choose to make totally depends on the method and the amount of time you wish to spend. The method that I’m sharing today is one that requires zero prep & is the easiest way to make a prime rib that I’ve ever made and it comes out perfectly cooked every single time.

The other prime rib recipes that I have on here are also perfect, but both require a little more work and prep than this one does. I feature one that’s a Deep Fried Prime Rib, and the crust that forms on that baby makes my mouth water when I think about it. It’s totally different, but totally delicious. And secondly, I feature another one that is roasted which I developed along with the chefs at the Certified Angus Beef commission and it features a delectable crust that will not fall off when you slice it. All are delicious!

This particular recipe (in contrast to the others here on the Mrs)  just can’t be screwed up, no matter what you do. Well, I’ll take that back. If you fail to remove it from the oven and just let it cook all day long – it will definitely be ruined. But, if you follow these super simple directions, you will end up with a perfectly cooked prime rib each and every time with very minimal effort.

You just sprinkle it with the seasonings, pop it in the oven at high heat for 20-30 minutes (depending on how big your prime rib roast is, refer to the recipe below), and then…

Turn off your oven and walk away for 2 hours. Turn on a Hallmark Christmas movie. Take a nap (but set an alarm haha). Read a book. But whatever you do, don’t open up that oven door for 2 hours… no matter how good it smells. Just leave it be. It’s working some magic in there and if you disturb it, the magic will all be done. Don’t take away the prime rib’s magic. -grin-

Easy peasy. Super simple. Delicious, tender, perfectly cooked prime rib each and every time. Enjoy!

Foolproof Prime Rib


  • 4 pounds boneless prime rib roast
  • 1/4 cup olive oil OR softened unsalted butter
  • 1 heaping teaspoon black pepper
  • 6 tablespoons of chopped fresh herbs I like a combo of thyme, rosemary, & basil or parsley.
  • 6-8 cloves minced garlic
  • 1 teaspoon garlic salt


  • Place roast on a plate and bring to room temperature for best results, about 3-4 hours.
  • Preheat your oven to 500 degrees.
  • Combine butter or oil, pepper, fresh herbs, & minced garlic in a bowl & stir to blend. Spread butter/oil mixture evenly over entire roast. Season roast generously with garlic salt.
  • Roast the 4 pound prime rib (see cook's note if using a larger or smaller roast) in the preheated oven for 20 minutes. Turn the oven off, leaving the roast in the oven with the door closed. Do not open the oven door at all for exactly 2 hours. Remove roast from the oven - let rest for 10 minutes. Slice and serve.
