Method

  1. 1Coat the pork tenderloin generously with Jerry's Faves 'The Classic' BBQ dry rub.Trim the silverskin first — the thin pearly membrane along the top. It does not render and it bows the tenderloin as it shrinks. Pat dry, then coat generously.
  2. 2Set up a charcoal grill for two-zone cooking with Kingsford briquettes.Coals banked to one side, a third to a half of the grate left empty. Tenderloin is the leanest cut on the pig and direct heat alone takes it from raw to dry in minutes.
  3. 3Sear over direct heat, then finish over indirect heat for full control.Sear first, then move across. Going sear-last on something this thin means the outside is already cooked before the crust forms.
  4. 4Pull the pork at 145°F and rest until it climbs to about 152°F.145°F is the USDA safe temperature for whole-muscle pork and it is meant to be slightly pink. Pull there and let carryover take it to about 152°F.
  5. 5Slice and serve.Slice across the grain after resting. Cook it whole rather than as medallions — pre-cut medallions have far more surface area for their volume and dry out much faster.

What each ingredient is doing

Pork tenderloin
The leanest cut on the pig with almost no intramuscular fat, which is why the 145°F target is a genuine ceiling rather than a suggestion. It also cooks fast for its size.
BBQ dry rub
A savoury all-purpose blend. On a lean cut the rub is doing more of the flavour work than it would on a fatty one, so be generous.
Charcoal briquettes
Steady and predictable, which suits a two-zone setup over a short cook. Lump burns hotter with more drift.

Pitmaster tips

  • Trim the silverskin before the rub goes on. It is the thin, pearly membrane along the top, and it does not render or soften — left on, it shrinks and bows the tenderloin as it cooks.
  • Tenderloin is the leanest cut on the pig, which is exactly why two-zone matters. Direct heat alone takes it from raw to dry in a couple of minutes with no margin in between.
  • Sear first, then move it across. Going sear-last on something this thin means the outside is already cooked before the crust forms.
  • 145°F is the current USDA safe temperature for whole-muscle pork, and it is meant to be slightly pink in the middle. The old well-done advice predates modern pork and is what gives tenderloin its dry reputation.
  • Pull at 145°F and let carryover take it to about 152°F while it rests. Resting a lean cut is not optional — cut into it straight off the grill and the juice ends up on the board.
  • Cook it as one whole piece and slice after. Medallions cut before cooking have far more surface area for their volume and dry out much faster.
  • Trim the silverskin before seasoning. It never softens and it contracts as it cooks, bowing the tenderloin into a curve.
  • Cook it whole and slice after. Medallions cut before cooking have far more surface area for their volume and dry out much faster.
  • Tuck and tie the thin tail if there is one, or it will be dry by the time the thick end is safe.
  • Slightly pink at 145°F is correct. The USDA lowered the whole-muscle pork target in 2011, and cooking to the old 160°F is why tenderloin has a dry reputation.

If it goes wrong

It is dry
Past 145°F. Use a thermometer rather than a timer and pull the moment it reads — tenderloin has no fat reserve to recover from overcooking.
It curled as it cooked
The silverskin was left on. Slide a thin knife under it and strip it off before seasoning.
The outside burnt before the middle was done
Too long over direct heat. Sear for colour only, then move to the indirect side to finish.
It cooked unevenly end to end
Tenderloin tapers. Tuck the thin tail underneath and tie it, or start that end further from the coals.
The centre was pink and I was worried
Slightly pink at 145°F is correct and safe for whole-muscle pork. The rules changed in 2011 and most home cooks have not updated.

Ways to change it up

Bacon-wrapped
Wrap the seasoned tenderloin in bacon before grilling. It bastes an extremely lean cut as it renders — real insurance.
Brined
A 30–60 minute brine adds a margin of safety on a lean cut. Pat very dry afterwards or the crust suffers.
Stuffed
Butterfly, fill with apple and sage or cheese and jalapeño, roll and tie. Adds time on the indirect side.
Reverse sear
Indirect to 130°F then a hard sear to finish at 145°F. More control on a thicker tenderloin.
Glazed
Honey mustard or a BBQ sauce in the last five minutes on the indirect side. Late and thin, since both are sugary.

What to serve it with

  • Apple sauce or a fruit chutney — an old pairing for good reason.
  • Roast or mashed potatoes.
  • Something green and sharp against a mild cut.
  • A pan sauce or mustard on the side.
  • A cold cider.

Storage & reheating

Sliced pork tenderloin keeps 3–4 days in the fridge. Because it is so lean, it reheats badly with dry heat — warm the slices covered with a splash of stock or juice at a low temperature, or use them cold in sandwiches and salads, which is honestly the better outcome. Store it as a whole piece and slice as you go if you can; whole meat dries out far more slowly than slices.

Cooked tenderloin freezes for about three months, though the texture tightens. Raw tenderloin freezes better — up to six months wrapped airtight. Thaw either in the fridge overnight rather than on the counter.

FAQ

What temperature should pork tenderloin be cooked to?

Pull it at 145°F and rest it. That is the USDA safe temperature for whole-muscle pork and it leaves the centre slightly pink, which is correct and safe. Cooking to 160°F or beyond is what makes tenderloin dry — it has almost no fat to protect it.

Is pork tenderloin the same as pork loin?

No, and they are not interchangeable. Tenderloin is a small, thin muscle about a pound or so that cooks in 20–30 minutes. Pork loin is a much larger roast that takes well over an hour. Using loin timings on a tenderloin will ruin it.

Why cook it over two zones instead of just grilling it?

Because it is lean and thin. Direct heat browns the outside in a couple of minutes, which is not long enough for the middle to come up — so you sear over the coals for crust, then move it to the indirect side where it can reach 145°F without the surface overcooking.

Do I need to brine pork tenderloin?

It is not required if you pull it at 145°F, which is where most dry tenderloin actually goes wrong. A short brine does add insurance and seasons the meat through, but accurate temperature and a real rest do more for juiciness than a brine covering for an overcooked piece of meat.

More information, cause recipe back stories are stupid

No 500-word life story — just the good-to-know stuff on what’s actually in this cook. Here’s the rundown on every real ingredient, health and nutrition wise.

Pork
Pork is a protein-rich meat that's especially high in thiamine (vitamin B1) — more than most other meats — plus B6, niacin, and selenium. Tenderloin and loin are lean; shoulder and belly are richer, so portion the fattier cuts.
