How To Cook Costco Standing Rib Roast: The Quick Version
Here are the instructions for cooking a Costco seasoned standing rib roast:
Traditional Method
- Preheat oven to 500°F
- Place prime rib in a shallow roasting pan on the center rack and cook for about 25 minutes
- Turn oven temp down to 350°F
- Roast until internal temp reaches around 115°F
- Remove prime rib from oven and let rest for 20-25 minutes
- Cut the twine holding the bone to the roast before slicing and serving
Reverse Sear Method
- Take prime rib out of the refrigerator and let stand at room temp for 60-90 minutes
- Preheat oven to 225°F
- Place prime rib in a shallow roasting pan on the center rack and cook until internal temp reaches 120°F (a 12 lb prime rib will take 3-4 hrs)
- Remove prime rib from oven and let rest for 30 minutes
- Turn oven temp up to 500°F
- Place prime rib back in oven for about 10 minutes to brown – final internal temp should be around 130°F
- Remove prime rib from oven and let rest for about 5 minutes
- Cut the twine holding the bone to the roast before slicing and serving
The reverse sear method is considered superior as it produces a more consistent doneness throughout the roast. Always use an instant read thermometer and remove the roast when it reaches 115°F for medium rare. The temperature will continue rising to 130-135°F as it rests.Plan on about 1 lb of bone-in prime rib per adult. A 10 lb roast will take around 4 hours to cook.

Pre-Cooking Preparation
Thawing and Marinating
Thawing frozen rib roast is crucial for optimal results. Place your roast in the refrigerator, allowing it to thaw slowly over 2-3 days. Quick-thaw methods can compromise texture.
Marinating? Consider a blend of olive oil, garlic, and fresh herbs. Let the flavors infuse for at least four hours, preferably overnight. This slow absorption builds a depth of flavor that brings your rib roast to life.
Tying and Seasoning
Tying the roast ensures even cooking. Use butcher’s twine to secure the roast, wrapping it tightly but without distorting its shape.
Seasoning? Be bold. Generously coat with sea salt, cracked pepper, minced garlic, and fresh herbs. Rub it in thoroughly, ensuring every inch is covered. This sets the foundation for how to cook Costco standing rib roast like a pro.

FAQ On How To Cook Costco Standing Rib Roast
How do you choose the best standing rib roast at Costco?
Opt for USDA Prime—Costco’s meat department offers some of the finest cuts. Look for marbling that runs throughout the meat. A bone-in ribeye roast is ideal, enhancing flavor.
Always check the sell-by date to ensure freshness. Trustworthy quality ensures an unforgettable holiday meal.
How should you season a Costco standing rib roast?
Season generously with sea salt, cracked black pepper, garlic, and fresh herbs like rosemary and thyme. A good rub locks in moisture and flavor.
Allow the seasoning to sit on the meat for at least an hour, or overnight if possible, for deeper penetration.
What is the ideal cooking time and temperature?
Preheat your oven to 450°F, then reduce to 325°F after placing the roast inside. Cooking time varies—generally, 15 minutes per pound.
Use a meat thermometer to check: 120°F for rare, 130°F for medium-rare. Always account for resting time to let juices redistribute.
Should you sear the rib roast before roasting?
Searing is key. Sear all sides in a hot skillet before transferring to the oven. This locks in juices and creates a flavorful crust. Ensure the skillet is preheated properly for an even, golden-brown sear, turning every couple of minutes to perfect each side.
How can you tell when the roast is done?
Use an instant-read meat thermometer. Insert it into the thickest part of the roast. For medium-rare, look for 130°F.
After removing from the oven, cover with aluminum foil. Let it rest for 20-30 minutes, during which the temperature can rise another 5-10 degrees.
Why is resting the roast important?
Resting the roast allows the juices to redistribute evenly throughout the meat, ensuring each slice is juicy and flavorful. Skipping this step can result in a dry, less flavorful roast. Tent with aluminum foil and let it rest for at least 20 minutes.
Can you use a convection oven to cook the roast?
Yes, you can use a convection oven. Set it to 425°F initially and then drop to 300°F. Convection circulates hot air, cooking the roast more evenly and sometimes faster. Keep an eye on internal temperature, as convection may shorten cooking times.
What are some side dishes to serve with a standing rib roast?
Consider classic sides like Yorkshire pudding, orzo pilaf, and roasted vegetables. Mashed potatoes, gravy, and a fresh garden salad also work wonderfully.
Complement the rich flavors of the rib roast with a balanced array of side dishes to enhance the meal.
How should you carve the standing rib roast?
Use a sharp carving knife. First, cut along the bones to remove them completely. Then, slice against the grain in even, 1/2-inch thick slices. Carving carefully ensures even pieces; the right technique makes serving easier and the dining experience better.
What can you do with leftovers?
Transform leftovers into delicious dishes. Think hearty sandwiches with horseradish sauce, or dice and add to beef stew.
Leftover rib roast can also be repurposed into tacos, stir-fries, or even as a protein addition to salads. Store properly in the refrigerator to maintain freshness.
