Quick Answer

Salt Costco's bone-in pork rib roast generously, sear, slather with a mustard-herb crust, and roast at 350°F until 145°F internal — about 90 minutes. Carve at the table like a small standing rib roast. Total 110 minutes; serves 8.

The Costco rack of pork — also called a pork rib roast — is a dramatic cut that looks like a standing rib roast but costs a fraction of the price. Costco carries it frenched and ready to season. A simple herb and garlic crust is all it needs. Roast it low and slow to 145°F and the result is a juicy, deeply flavored centerpiece that feeds eight people for less than $40.

Instructions

  1. 1

    Remove the rack of pork from the fridge 1 hour before cooking. Pat dry with paper towels — a dry surface is key to a good sear and crust.

  2. 2

    Preheat oven to 450°F. Mix garlic, rosemary, thyme, olive oil, salt, pepper, paprika, and garlic powder into a paste.

  3. 3

    Rub the herb paste all over the surface of the pork, including between the bones. Place bone-side down in a roasting pan or large oven-safe skillet.

  4. 4

    Roast at 450°F for 15 minutes to develop a golden crust.

  5. 5

    Reduce oven temperature to 325°F. Continue roasting for 60–75 minutes until an instant-read thermometer inserted into the thickest part of the meat (not touching bone) reads 140°F.

  6. 6

    Remove from the oven and tent loosely with foil. Rest for 20 minutes — the internal temperature will carry over to 145°F, the USDA safe temperature for pork.

  7. 7

    Carve between the bones into individual chops. Finish with flaky salt and serve with pan drippings or a simple pan sauce made from the roasting juices.

Frequently Asked Questions

What is a rack of pork from Costco?+
A rack of pork (also called a pork rib roast or pork standing rib roast) is a bone-in pork loin with the rib bones attached and frenched — meaning the bones are cleaned and exposed for presentation. Costco typically sells them as 6–8 bone racks, making them ideal for dinner parties and holiday meals.
What temperature should I cook a Costco rack of pork to?+
The USDA recommends cooking pork to an internal temperature of 145°F, followed by a 3-minute rest. For a rack of pork, pull it from the oven at 140°F — it will carry over to 145°F while resting. Going above 155°F makes the meat noticeably drier.
How long does it take to roast a rack of pork?+
After the initial 15-minute high-heat sear at 450°F, the rack takes about 15–18 minutes per pound at 325°F. A 4-pound rack takes approximately 60–70 minutes. Always use a meat thermometer — oven temps vary significantly.
Should I cover a rack of pork while roasting?+
No — roasting uncovered is what develops the herb crust. However, cover the bone tips with foil if they start to darken too quickly. After the roast is done, tent with foil during the resting period to retain heat without steaming the crust.
How many people does a Costco rack of pork feed?+
A standard Costco rack of pork (6–8 bones) feeds 6–8 people as a main course, with one bone-in chop per person. If serving with substantial sides, an 8-bone rack can comfortably feed 8–10 guests.
