How to Cook Costco’s Rack of Pork!

You can tell it’s a holiday weekend when Costco restocks the shelves with their Kirkland Signature Rack of Pork.  These roasts are perfect for a holiday feast and look impressive when served on the bone.

Costco sells two versions of this product.  One is unseasoned and still in the cryovac while the other has been fully seasoned.  The coking instructions are the same for either version.

How to Cook a Rack of Pork

Cooking the rack of pork that you get from Costco is incredibly easy because it has already been pumped with a salty pork broth solution that is going to keep the meat extremely juicy and flavorful even if you overcook it a little.

There is a thin fat cap on one side of the roast but you do not need to do anything to it other than add seasoning as it will render while cooking.

Regardless of which cooking method you employ you want to cook the pork to an internal temperature of 140-145F.  Anything less than 140F is not safe to eat and going past 145F starts to make the meat dry and tough.

Oven Roasted

Below is a nice video recipe for roasting a rack or pork in the oven along with some root vegetables.

The roast gets coated with a seasoning blend and is roasted at 325F along with the vegetables for  about an hour and 15 minutes to an hour and 30 minutes.  Again, your target internal temperature is 140-145F.

Slow Smoked

I enjoy slow cooking these roasts on my pellet grill to get a little smoke flavor into the meat.

I coat the roast with a sweet/salty/spicy rub and then smoke it at 225F for 2.5 hours or until an internal temperature of 145F is reached.  I give the roast a little baste of barbecue sauce right before it comes off the pit for a little more flavor and color.

How Many People Can You Feed?

This rack comes in a cut that weighs about five pounds and has eight bones.  When you subtract the weight of the bones you will have about 4.5 pounds of meat.

A very natural serving size is a thick slice that has one bone.  Since there are eight bones per roast then you can carve out eight servings.

The question is, do you want people to be able to have one or two servings?

You can count on feeding eight people with this roast as long as you have plenty of side dishes.

    I’ve been making this for about 5 or 6 years now, and it’s always a hit. I’ve tried it with some different seasonings, but always come back to just salt & pepper. One thing I can say for sure, if you leave it in the oven until 145, it will be over-cooked.

    I sear the fat side for 2 minutes in a 12″ cast iron skillet, flip it over, and put it in a 450* oven for 10 minutes, to make sure the fat is crispy. Then, lower to 300 and cook about 25 minutes, or until 135 on a meat thermometer. Pull from the oven and place on a heated dish, and cover with foil. Let rest for 10 min while you finish your sides, and make a pan sauce from the drippings. Carve, and serve. So simple, but so elegant!
