Understanding Beef Cuts: A Primer
Before we dive into the specifics of top sirloin roast and prime rib, it’s essential to understand how beef cuts are classified. Beef cuts are typically divided into eight primal cuts, which are then further subdivided into sub-primals and retail cuts. The eight primal cuts are:

Each primal cut has its unique characteristics, tenderness, and flavor profile, which are influenced by factors such as the animal’s breed, age, and diet.
The Sirloin Primal Cut
The sirloin primal cut is located near the rear of the animal, between the ribs and the round. It’s a leaner cut, known for its tenderness and rich flavor. The sirloin primal cut is further divided into three sub-primals:
- Top sirloin
- Bottom sirloin
- Sirloin tip
The top sirloin sub-primal is the most tender and prized part of the sirloin primal cut.
Top Sirloin Roast: A Cut Above the Rest
Top sirloin roast is a retail cut that comes from the top sirloin sub-primal. It’s a boneless cut, typically weighing between 2-4 pounds, and is known for its rich flavor and tender texture.

Top sirloin roast is a popular choice for special occasions and holidays, as it’s relatively easy to cook and serves a crowd. It’s also a versatile cut, suitable for a variety of cooking methods, including oven roasting, grilling, and pan-frying.
The Rib Primal Cut: Home of the Prime Rib
The rib primal cut is located between the chuck and the loin primal cuts. It’s a rich, tender, and flavorful cut, known for its marbling (fat content) and rich beef flavor. The rib primal cut is further divided into two sub-primals:

The ribeye roll sub-primal is the most prized part of the rib primal cut, and it’s from this sub-primal that prime rib is cut.
