Pork tenderloin (French: filet mignon de porc) is the long, narrow muscle located beneath the pork loin, along the inside of the backbone. It is one of the most tender cuts of pork and is naturally lean. A whole tenderloin commonly weighs several hundred grams, with size varying by animal and supplier. It is suited to quick cooking and portioned service.
Remove the tenderloin from beneath the loin and trim away the silverskin, a tough membrane that does not soften during cooking. Remove any excess fat and the small side muscle if required by the recipe. The tenderloin may be left whole, tied to an even thickness, cut into medallions or butterflied for stuffing.
Do not confuse pork tenderloin with pork loin. The loin is a much larger muscle along the back and is sold as chops or roasts; the tenderloin is smaller, narrower and cooks more quickly. The two cuts have different portion yields, cooking times and menu costs.
Pork tenderloin can be seared whole and finished in the oven, grilled, roasted or cut into medallions for quick pan-cooking. It is also suitable for stuffing or wrapping. Because it is lean, avoid excessive cooking and use a calibrated thermometer with the safe cooking process required in your jurisdiction. Rest briefly before slicing across the grain.
Example: sear a trimmed pork tenderloin, finish gently in the oven and serve with a mustard jus; alternatively, cut into medallions and sauté quickly with mushrooms and shallots.
Specify whole or portioned tenderloin, weight range, trim standard and whether the chain or side muscle is included. Record raw weight, trim loss and cooked yield to establish a consistent portion cost.
Chef’s tip: Remove the silverskin before cooking and tie uneven sections if necessary for consistent thickness. Do not overcook; the narrow tail end may need to be folded or tied to prevent it from drying before the thicker centre is ready.
Key distinction: Pork tenderloin is a small, tender muscle beneath the loin; pork loin is a larger cut with different cooking characteristics.
