Costco Seasoned Prime Rib Cooking Instructions

Traditional Method:

1. Preheat oven to 500° F
2. Remove the plastic wrap foam tray from the aluminum container and place the Prime Rib into the oven on the center rack.
3. Cook for 25 minutes
4. Turn the oven down to 200° F and continue to cook for 20 to 35 minutes per pound, or until the internal temperature reaches the desired temperature (see below for internal temperatures)
5. Remove the Prime Rib from the oven and let rest for at least 3 minutes
6. Cut the twine holding the hone to the Prime Rib, place it on the cutting board, then slice and serve

Reverse Sear Method:

1. Take Prime Rib out of the refrigerator and let stand at room temp for 60-90 minutes
2. Preheat oven to 225° F
3. Place Prime Rib in a shallow roasting pan place on the center rack of the oven and cook until internal temperature of 120° F (a 12 lb Prime Rib will take 3-4 hrs)
4. Remove the Prime Rib from the oven and let rest for 30 minutes
5. Turn oven temp up to 500° F
6. Place Prime Rib back in the oven for about 10 minutes to brown – check the internal temperature before removing
7. Remove the Prime Rib from the oven and let rest for about 5 minutes
8. Cut the twine holding the bone to the roast before slicing and serving

Note: The roast will continue to cook a couple of degrees more after you remove it from the oven. Remove the Prime Rib a few degrees short of what you prefer the temperature to be. See below for the temperature guide.

Many people swear that the reverse sear method is far superior to the traditional method. Both will yield tasty results, but the reverse sear should produce a more consistent and uniform doneness throughout the entire roast.

Prime Rib Internal Temp Guide

Use these temperatures when making a standing rib roast. The temperature is the same whether you’re making a bone-in or boneless roast. The preferred internal temperature is usually medium rare.

• Rare Prime Rib: 120-129°F (Bright red center, lukewarm)
• Medium Rare: 130-134°F (Bright red center, pink edges, warm)
• Medium: 135-144°F (Pink and warm throughout)
• Medium Well: 145-154°F (Slightly pink center and warm throughout)
• Well Done: 155-164°F (Very little pink)

Always use an instant-read thermometer for measuring the internal temperature for the most accurate read.  Thermapen is the best you can get and is used by the pros (but it’s pricy); a very capable but less pricy option is the Lavatools Javelin Pro. Finally, Meater also makes a great Bluetooth-enabled smart meat thermometer option if you’re looking for more bells & whistles.
