A long-established Prime steakhouse supplier whose bone-in and dry-aged rib roasts suit a showpiece holiday roast.

Not for: Small households or anyone cooking on a tight budget, who would do better with a Choice boneless ribeye roast.

Grade, not name: Check for USDA Prime or upper Choice on the label. "Prime rib" is a cut name, not a grade, so the label alone guarantees nothing.
Size: Allow about one rib bone for every two people. This is the standard sizing rule for bone-in rib roasts.
Bone-in vs boneless: Bone-in gives more even cooking and flavor. Boneless is easier to carve. The bones insulate the meat and act as a built-in rack.
End of the rib section: The loin end (ribs 10–12, called first cut) has a larger, leaner eye. The chuck end has more cap and fat. Choose by whether you prefer a uniform eye or a richer spinalis cap.
Pull temperature: Pull around 120–125°F for medium-rare and let carryover finish it. Large roasts keep rising several degrees while they rest.

Assuming a roast labelled "prime rib" is USDA Prime.
Roasts tied with added fat or seasoning when the listing doesn't state the grade.
Undersized roasts, which overcook before they develop a crust.

No. It names the cut, and most roasts sold as prime rib are Choice.
