This is a premium, well-marbled cut from the rib primal, specifically ribs 6 through 12, broiled to render its fat and create a deeply savory, beefy flavor. The texture is a luxurious combination of tender, juicy lean meat and rich, unctuous fat, with a satisfying chew. Nutritionally, it is a dense source of high-quality protein and fat, providing significant calories and essential nutrients like iron and B12.

↓ Full nutritionPeople adore the profound, beefy umami flavor that intensifies with broiling, creating a caramelized, slightly crispy exterior. The luxurious mouthfeel from the rendered fat makes it a celebratory centerpiece for meals, deeply rooted in barbecue and steakhouse culture.
The high fat and calorie density can be a concern for those monitoring energy intake or managing heart health. The cooking method (broiling) can produce heterocyclic amines (HCAs) if charred. To counteract, practice portion control, trim excess fat before eating if desired, and avoid charring by cooking to the recommended internal temperature without burning. Pair with fiber-rich vegetables like broccoli or a leafy salad to add bulk and nutrients.
The 'ribeye' steak is actually cut from this same primal section (ribs 6-12), but from the ribeye muscle within the rib, making it a more specific, boneless portion of the same flavorful area.

What is the difference between a ribeye steak and a rib steak?
A ribeye is a boneless steak cut from the rib primal. A rib steak (or 'cowboy steak') is cut from the same area but includes the bone, which can add flavor during cooking.
Why is this cut called 'prime'?
'Prime' is the highest quality grade given by the USDA, indicating abundant marbling (intramuscular fat), which results in superior flavor, juiciness, and tenderness.
How should I cook this cut for best results?
Broiling, grilling, or pan-searing followed by oven finishing are ideal. The goal is a high-heat sear for a crust, while cooking to your preferred doneness (medium-rare is often recommended to keep it juicy) and allowing it to rest before slicing.
