Cut Location: Both prime rib and standing rib roast come from the same section of the cow—the rib primal—but the difference lies in how they're prepared.
Prime Rib Quality: The term "prime rib" is often associated with high-quality beef, but it doesn't necessarily mean the roast is from USDA Prime-grade beef.
Preparation: A standing rib roast is usually cooked as a whole roast, often with the ribs left on to "stand" during cooking, which helps distribute heat evenly.
Bone-In vs. Boneless: Standing rib roast is usually bone-in, meaning the ribs are left attached to the meat.
Cooking Method: Both cuts are typically roasted in an oven, but the standing rib roast is more often cooked with the ribs standing up.
Serving Style: The standing rib roast is often served as a whole piece and carved at the table, giving it a more dramatic presentation.
Cost and Availability: Prime rib is often considered a more premium option, especially in restaurants, and may be more expensive due to the perceived higher quality.
