Seasoned Bone In Standing Rib Roast at Costco – Cooking Instructions
Looking for a Holiday Prime Rib roast? You might want to consider the Kirkland Signature Standing Rib Roast at Costco. It’s a seasoned, bone-in beef roast, and it’s all ready to cook – great beef entree option for a holiday party or family dinner. This will slow roast in the oven, so plan on a minimum of about 4 hours for a 10lb rib roast. Seasoned with roasted garlic and Kirkland Signature olive oil, this roast is easy and it’s a crowd pleaser!
ProTip: Calculate out this rib roast’s cooking time (based on the size of your roast, and how well done (or rare) you like it cooked) the day before you need to roast it so you can be sure to set aside enough time and plan how/when to cook any side dishes. It’s not a significant amount of “active” time but does take a number of hours in the oven!
Serve your standing rib roast at Costco with mac n’ cheese, a nice cabernet and cheesecake or macarons for a quick and delicious holiday meal all from Costco! Looking for instructions for the Seasoned Rack of Pork or Garlic Rosemary Rack of Pork?

This item not part of the core product line at Costco, but we do see it return each year for the holidays! You can check local Costco inventory on this.

Product Label
Please double check the product label on the actual rib roast at your local Costco – these are locally prepared in the deli department and ingredients or cooking instructions may vary slightly from Costco to Costco location.
Although it is not officially labeled as Gluten Free or Keto – from my reading of the label I don’t see any gluten in the ingredient list and think this would be Keto friendly as well.

Should I put this on a roasting rack? And how long should it be set out ahead of cooking?
Apologies I was offline for a few days for the holidays – hopefully you found your answer but I did want to answer in case anyone else has the same question in the future. No, you don’t need to place it on a rack – you can cook it right in the container it comes in (I personally move it to a ceramic dish, but definitely do not need to do that) and it doesn’t need to come to room temperature before roasting. If you’re trying to reduce oven time (juggling multiple items) you could let it come to room temperature and that would probably reduce cook time slightly (I’ve never done it so I can’t say by how much, but logically it should reduce it a small amount – just use a meat thermometer to test it).
Will this be available for Thanksgiving?
I expect it will be in stores soon – any day now. I don’t have confirmation on that officially, but it’s a very popular item and I’ll be shocked if its not back this year. I will update this post with updated pricing and availability as soon as I see it in-store!
