Is there a difference between pork fillet and pork tenderloin?
This is the core of the confusion. The terms "pork fillet" and "pork tenderloin" refer to the exact same cut of meat. In North America, the cut is most commonly known as pork tenderloin, while in the UK and other parts of the world, it is often called pork fillet. Since they are the same, their fat content is also identical. Both are a long, thin muscle that runs along the pig's backbone. Because this muscle is rarely used for movement, it is exceptionally tender and contains very little fat.
Why pork tenderloin is a lean option
Pork tenderloin, or fillet, stands out as one of the leanest cuts available. Unlike pork loin, which is a wider cut that often includes a fat cap, the tenderloin has minimal to no visible fat. This makes it a heart-healthy option that is low in saturated fat. Its leanness means it cooks quickly, but also that it can dry out if overcooked, so proper cooking techniques are essential to retain its moisture and delicate flavor.
Comparing fat content: Pork tenderloin vs. pork loin
It is important not to confuse pork tenderloin with pork loin, as they are different cuts with different fat content. The term "loin" refers to a larger, thicker cut from the back, whereas the tenderloin is a smaller, more delicate cut. This distinction is crucial for both cooking and nutrition planning. The higher fat content in pork loin provides more moisture and flavor during longer, slower cooking methods, while the tenderloin thrives with quick, high-heat applications.

Cooking techniques for lean pork
Because pork fillet/tenderloin is so lean, it requires careful cooking to prevent it from becoming dry. Here are some techniques that work best for this delicate cut:
- High-Heat Searing: A quick sear in a hot pan or on the grill creates a flavorful crust while keeping the inside tender and juicy. This method is perfect for medallions.
- Roasting: For a whole fillet, roasting at a high temperature for a short time is ideal. This is often done after an initial sear to lock in juices.
- Marinating: Since it has a mild flavor, tenderloin readily absorbs marinades. A good marinade will not only add flavor but also moisture, protecting the meat from drying out.
- Stir-frying: Cutting the fillet into thin strips and stir-frying them quickly ensures they are cooked through without losing their tender texture.
The misconception about different cuts
The confusion between pork fillet and pork tenderloin is largely a matter of regional terminology. Other cuts, like pork loin, are structurally and nutritionally different, and it's these differences that cause the varied fat content. Always check the label or ask your butcher to ensure you are buying the cut you intend to. The pork tenderloin/fillet is a small, premium cut, whereas the loin is a much larger, more robust cut.
Conclusion: The leanest cut for quick cooking
To definitively answer the question, neither pork fillet nor pork tenderloin has more fat, as they are the same cut of meat. The defining characteristic of this versatile cut is its exceptional leanness. With minimal fat and marbling, it offers a heart-healthy protein source that is ideal for quick-cooking methods. For those prioritizing low-fat meat, the pork tenderloin/fillet is an excellent choice. By understanding that the two names are interchangeable and recognizing the difference from other pork cuts like the pork loin, you can make informed decisions in the kitchen and at the grocery store.
