Here’s the first thing you need to know: they are essentially the same cut of beef. Yes, you read that right. Both come from the exact same place on the cow—the primal rib section, ribs six through twelve.
So why the different names? It’s all about labeling and presentation. Think of it like your favorite jeans: they’re the same denim, but one pair is “vintage wash” and the other is “distressed.”
A rib roast is the straightforward, no-frills name for the cut. A prime rib roast is the same cut, but it carries a promise of higher quality—usually from a younger animal with more marbling. But wait, there’s more!
