Pork Tenderloin
The psoas major — a slim strap tucked beneath the spine that stabilizes the animal rather than moving it, and so never toughens. It's the most tender muscle on the pig and among the leanest: a whole one runs about a pound and two inches across, under 3% fat, with no bone and hardly any waste.

Twenty minutes from fridge to dinner, and four from perfect to chalky.
Buy it if
You're cooking for two or three and you want a fast, lean roast with no bone and nothing to trim.
It is not pork loin, and the mix-up is expensive. The loin is the big muscle that sits on top of the spine and can weigh ten pounds. The tenderloin is the small one underneath it, weighing about one. Recipes and packaging blur the two constantly, and nothing transfers between them: a tenderloin is finished in twenty minutes, a loin roast takes an hour or more. Following a loin recipe with a tenderloin produces something closer to jerky.
Lean is the entire constraint. With no marbling, there's no fat melting into the muscle to cover for you, and no buffer at all against an extra few minutes. Everything people do to this cut — brining, stuffing, wrapping it in bacon, pulling it early — exists to work around that one fact.
Mild, and honest about it. Flavor in pork lives mostly in the fat, so the leanest muscle on the animal is also the quietest. That isn't a flaw so much as a job description: the tenderloin is a carrier for a rub, a marinade, or a sauce, and it takes them unusually well. If you want the meat itself to be the point, buy a rib chop or a piece of belly.
The same muscle costs a fortune on a cow. Beef tenderloin is the most expensive cut on the steer; pork tenderloin is among the cheapest on the pig. It's the identical muscle in the identical place doing the identical nothing — the price gap is about the animal, not the anatomy.

How to cook Pork Tenderloin
| Best methods | Roast Pan sear Grill Sous vide Smoke |
|---|---|
| Skip | Braise |
| Cook to | Pull at 140–142°F and let carryover carry it to 145°F, then rest three minutes. This lean, five degrees is the whole difference between juicy and chalky. |
High heat, short time, thermometer. Sear it hard on all sides to build color, then finish in a hot oven — a whole tenderloin only needs about fifteen to twenty minutes total, and there is no version of this cut that benefits from going slowly.
Don't braise it. There's no connective tissue to convert, so long wet cooking just shreds the fibers and gives you nothing back.
Carryover is a real factor on something this small. It will climb several degrees off the heat, which is why it comes off the pan before it reads done, not when it does.

Common questions
Do I need to remove the silverskin?
Yes. It's the iridescent band running along one side, and it neither renders nor softens — it contracts as it heats and bows the whole tenderloin out of shape. Slide a thin knife under one end, angle the blade up toward the membrane, and strip it off in lengths.
Why are the ends overcooked before the middle is ready?
Because a tenderloin tapers — one end is a thin tail perhaps half the thickness of the center, and it hits temperature long before the thick end does. Fold the tail back under itself and tie it with string so the whole thing is one even cylinder.
Is wrapping it in bacon worth it?
It's a reasonable fix for a real problem: the cut has no fat of its own, and bacon supplies fat and salt from the outside. The cost is browning — the bacon insulates the meat and gives up moisture, so you get no crust underneath. Cook it hot enough to crisp the bacon, or accept a soft exterior.
How many people does one feed?
Two or three. There's no bone and almost no trim, so a one-pound tenderloin is close to a pound of food — figure five or six ounces a head. They're usually sold two to a package for exactly that reason.
