Step 1

The first step is to make the marinade. You will need to prepare this two days in advance. To make, mix all ingredients for marinade. Mix well until combined and refrigerate overnight. This allows enough time to integrate all those wonderful flavors together.

Step 2

The second step is to marinade the ribeye. Place the prime rib on a rack in a large pan. Pour half the marinade over the top side and rub it all over. Next, flip the meat over, pour the rest of the marinade, and rub all over. Cover the pan and refrigerate overnight.

Step 3

Preheat your oven to 450 degrees Fahrenheit. Bake the meat for 30 minutes just until the outside of the meat is brown and seared. Then, lower the heat to 250 degrees Fahrenheit. Continue baking for another two hours or until your meat thermometer says 120 degrees.

Step 4

That's the temperature for medium-rare. If you want to increase the level of doneness, wait until the reading is 10 degrees higher for each state (i.e. 130 for medium, 140 for medium-well, etc.).

Step 5

Give your meat at least an hour to rest before slicing. This will give the juices time to settle in the meat, resulting in an even juicier and tastier prime rib.

Step 6

Slice and enjoy. Congratulations, you did it! It's time to reap your rewards. Carve that tender meat, have a taste, and serve with Au jus.
