The trick to making the perfect medium rare prime rib is all in the cooking. The ingredients are quite simple:
Standing Rib Roast
Sea or Kosher Salt
Now, I am so sorry, but we need to do just the littlest bit of math. So pay attention to this part.
First, make sure your rib roast is at room temperature by leaving it on the counter for 3-4 hours.
Now, take the EXACT weight of your rib roast that's listed on the package and multiply that by 5 minutes. That is the amount of time you put the roast in a preheated 500 degree oven. After that time is complete, shut your oven off and walk away. DO NOT open the door. Don't look at it. Don't even think about looking at it. Don't even breath next to it. I don't care how many times your fire alarm goes off. DON'T TOUCH THE OVEN for a total of two hours.
Mine was 5.005 pounds. So I put it in a preheated 500 degree oven for 25 minutes. I then shut the oven off and let it sit in there for exactly two hours.
And I got....
Eat with some homemade horseradish cream sauce.
And DEVOUR. Stay merry this Christmas and always stay hungry!!
The Perfect Prime Rib Recipe
Standing Rib Roast (about 1-1.5 servings per pound)
Sea or Kosher Salt
Stick of Butter, softened
1/2 Teaspoon Dried Thyme
1/2 Teaspoon Dried Garlic Powder
1/4 Teaspoon Fresh Ground Pepper
Make sure roast is at room temperature by leaving it out on the counter for 2-3 hours. Preheat oven to 500 degrees. Smear outside of roast fat side up with herb butter. Multiply weight of roast by 5 minutes for total cooking time at 500 degrees. Quickly put the roast in the oven on the middle rack. As soon as time is reached, shut the oven off and leave untouched for 2 hours. This will result in a perfect medium rare prime rib. The cuts on the outside will be more done than those on the inside, so you should be able to accommodate everyones tastes at the table. Enjoy!
