The King of Fat: The Ribeye
When it comes to commonly available beef cuts, the ribeye is almost universally recognized as the champion of fat. Derived from the rib section of the cow, this cut is famous for its extensive intramuscular fat, or marbling. The abundance of fat is not an accident; it's the very characteristic that makes the ribeye so juicy, tender, and intensely flavorful. As the steak cooks, the marbling melts into the muscle fibers, basting the meat from the inside and preventing it from drying out. This robust, beefy flavor makes it a favorite among steak connoisseurs, though its richness might be overwhelming for some. A bone-in ribeye, also known as a cowboy steak, can add even more flavor during the cooking process. The average ribeye can contain a significant amount of fat per serving, and while specific numbers vary based on size and grade, it consistently ranks at the top for fat content.
The Ultra-Premium Contender: Wagyu
For those willing to invest in a truly exceptional experience, Wagyu beef takes the concept of a fatty steak to an entirely new level. Wagyu cattle are genetically predisposed to develop significantly more intramuscular fat than conventional beef breeds. This results in an incredibly intricate, spiderweb-like marbling pattern that gives the meat a distinct, melt-in-your-mouth texture. The fat in Wagyu also has a different chemical composition, including a higher concentration of monounsaturated fatty acids, which melt at lower temperatures. This is what creates that unique, buttery sensation. Premium Wagyu cuts, such as A5 grade, can have fat percentages far exceeding typical beef. Due to this extreme richness, Wagyu is often served in smaller portions, as a little goes a very long way.
Other Notable Fatty Cuts
While the ribeye and Wagyu are the headliners, other cuts also offer a high degree of fat and flavor. The porterhouse and T-bone steaks, both cut from the short loin, feature a T-shaped bone separating a tenderloin filet and a New York strip. This combination provides a varied texture and flavor profile, and the presence of the bone adds to the juiciness. The porterhouse, in particular, comes from further back on the loin and contains a larger portion of the tenderloin. Short ribs are another high-fat cut, known for their rich, hearty flavor that benefits immensely from slow-cooking methods like braising. The fat and connective tissue break down during the long cooking process, resulting in incredibly tender, flavorful meat.
The Importance of Marbling
Marbling is the single most important factor when determining the fat content of a steak and, consequently, its flavor and tenderness. USDA grading, which assesses quality, is heavily based on the degree of marbling. Prime grade beef, for example, is reserved for the most heavily marbled cuts, followed by Choice and Select grades, which have progressively less marbling. A well-marbled steak not only has more flavor but also a more luxurious, juicy texture.
Comparison: Fatty vs. Lean Steak Cuts
| Feature | Ribeye Steak | Filet Mignon | Sirloin Steak | Wagyu Beef |
|---|---|---|---|---|
| Fat Content | Very High (Abundant Marbling) | Very Low (Minimal Marbling) | Moderate (Less Marbling) | Exceptionally High (Intense Marbling) |
| Tenderness | High (Melts in your mouth) | Very High (Extremely tender) | Moderate (Can be chewy) | Extreme (Melts like butter) |
| Flavor | Rich, Beefy, Robust | Mild, Delicate | Moderate, Hearty | Extremely Rich, Buttery |
| Texture | Succulent, Juicy | Silky, Smooth | Firm, Chewy | Unbelievably Tender |
| Best For | Grilling, Pan-Searing | Pan-Searing, Roasting | Grilling, Sautéing | Special Occasions, Minimal Cooking |
How to Cook a Fatty Steak for Best Results
To properly cook a fatty steak like a ribeye, you need to manage the rendering of the fat. The goal is to melt the marbling into the meat, not to burn the exterior fat. High-heat methods like grilling or pan-searing are ideal, but a popular technique is the reverse sear. This involves cooking the steak slowly at a low temperature until it reaches a desired internal temperature, then quickly searing it on a very hot surface to develop a delicious crust. This method ensures the fat renders evenly while preventing the steak from overcooking. For extremely fatty cuts like Wagyu, a gentle touch is key. Simply pan-sear for a short time to preserve its unique texture and flavor.

Conclusion
When asking what has the most fat on a steak?, the definitive answer depends on your preference for richness and budget. For a widely available and classic cut, the ribeye is the clear winner, prized for its abundant marbling and robust flavor. For the ultimate, most decadent experience, premium Wagyu beef, with its genetic predisposition for extensive fat, takes the crown. Other cuts like the porterhouse offer a balanced fat profile, while slow-cooked preparations can transform cuts like short ribs into tender, fatty delights. Ultimately, understanding the role of fat and marbling allows you to choose the perfect steak for your desired flavor and cooking method.
The Fattiest Cuts of Steak
- Ribeye: Often called the king of steaks, the ribeye is known for its intense marbling and high fat content, providing a rich, juicy, and beefy flavor.
- Wagyu Beef: This premium beef is genetically engineered for high intramuscular fat content, creating a decadent, melt-in-your-mouth texture.
- Short Ribs: While often braised, these ribs have a high-fat ratio that breaks down into tender, juicy meat during slow-cooking.
- Porterhouse: A large cut featuring both a tenderloin and a strip steak, the porterhouse combines different textures and flavors with substantial marbling.
- Brisket: This cut benefits from long, slow cooking, which breaks down its significant fat and connective tissue into a tender, flavorful final product.
- Ground Beef: The fat-to-lean ratio for ground beef can be controlled, with common blends like 80/20 and 70/30 offering varying levels of richness.
