Christmas Slow Roasted Prime Rib

Prep Time 15 minutes
Cook Time 4 hours 15 minutes
Refrigeration and Rest Time 45 minutes
Total Time 1 day
Servings 8 servings

Ingredients
  

  • 7-8 lb bone-in Prime Rib Roast with bones removed and tied back on
  • kosher salt
  • pepper
  • olive oil or clarified butter
  • 4-5 cloves minced garlic
  • soft butter

Instructions
 

18-24 hours ahead:

  • Place the prime rib on a wire rack on a cookie sheet. Heavily salt the prime rib and place uncovered into the refrigerator for 18-24 hours.
  • Remove prime rib from refrigerator 1 hour before baking to allow it to come closer to room temperature before cooking.

Time of Cooking:

  • Preheat oven to 250 degrees (not convection).
  • Mix together butter or olive oil with minced garlic. Spread mixture all over the roast. Pepper the entire roast.
  • Place roast uncovered into the preheated oven, with an oven-safe thermometer placed halfway through the roast, at the lower 1/3 of the roast closer to the bone, but not on the bone.
  • Roast until internal temperature is 115-120 degrees for medium-rare (about 4 hours for a 7-8 lb roast, or about 2 1/2 hours for a 5 lb roast). Remove from the oven, tent with foil, and let rest for 45 minutes, leaving thermometer in. (The roast will gain about 10-12 degrees while resting).
  • Heat oven to 450 degrees. Brush some soft butter over the roast and put back into the oven about 5-10 minutes to further brown the outside of the roast.
  • Remove from oven and it's ready to slice. Slice into 1/2 inch to 1 inch slices. (No resting time necessary as it's already rested).
  • Enjoy!
