Looking for a Thanksgiving or Christmas 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!
