Method

  1. 1Season the pork tenderloin with Maritime Madness Frig That's Good Everything seasoning, then layer on the Mighty Mesquite dry rub.Trim the silverskin first — the thin pearly membrane along the top. It never renders and it bows the tenderloin as it shrinks. Two rubs layered gives depth: an all-purpose base and a smoky mesquite over it.
  2. 2Set the Traeger Woodridge to 250°F with maple pellets and smoke the tenderloin, tracking the internal temperature with a MEATER wireless thermometer.250°F over maple is gentle enough to bring a lean cut up evenly. A leave-in probe matters here because the entire method hinges on catching 125°F, and opening a pellet grill costs real recovery time.
  3. 3Pull the tenderloin off the smoker right at 125°F internal — this sets up the perfect finish without overcooking.125°F is a handoff, not a finish. A screaming pan adds 20°F on a piece this size, so pulling at your target would take you well past it.
  4. 4Sear it in a blazing hot frying pan, building a deep, caramelized crust while the internal temperature climbs to 145°F.Dry the surface before the sear — a tenderloin that has been sitting in a smoker sweats, and that moisture has to boil off before browning starts. Turn it onto every face including the sides, since it is round in cross-section.
  5. 5Rest for 5 minutes, then slice to reveal the smoke ring and juicy centre.145°F rested is the USDA safe temperature for whole-muscle pork and it is meant to be slightly pink. Rest five minutes, then slice across the grain.

What each ingredient is doing

Pork tenderloin
The leanest cut on the pig with almost no intramuscular fat, which is why the temperature discipline matters so much. It also cooks fast for its size, so the window is narrow.
Everything seasoning
The all-purpose base layer. Salt is doing the seasoning work; the rest is background.
Mighty Mesquite rub
Layered over the base. Mesquite is assertive but a 50-minute cook is short enough that it perfumes rather than dominates.
Maple pellets
Mild and slightly sweet, which suits pork and balances a mesquite rub. A strong wood on top of a strong rub would be too much.
Cast iron or heavy pan
For the sear. It needs to be genuinely screaming — a lukewarm pan will cook the tenderloin further without ever building a crust.

Pitmaster tips

  • Trim the silverskin before seasoning. It never renders and it contracts as it cooks, bowing the tenderloin into a curve.
  • 125°F off the smoker, not 145°F. A screaming pan adds roughly 20°F on a piece this size — skipping that margin overshoots.
  • Dry the surface before the sear. A tenderloin that has been sitting in a smoker sweats, and wet meat will not brown.
  • Get the pan genuinely screaming. A lukewarm pan cooks the tenderloin further without ever building a crust, which is the worst of both.
  • Turn it onto every face including the sides. It is round in cross-section and top-and-bottom only leaves most of the surface pale.
  • Use a leave-in probe. The whole method hinges on catching 125°F, and opening a pellet grill costs several minutes of recovery.
  • Slightly pink at 145°F is correct and safe. The USDA lowered the whole-muscle pork target in 2011.
  • Tuck and tie the thin tail if there is one, or it will be dry before the thick end is ready.
  • Cook it whole and slice after. Medallions cut before cooking have far more surface area for their volume and dry out much faster.
  • Maple under a mesquite rub is a deliberate balance — do not double up on strong smoke and a strong rub.

If it goes wrong

It came out well done
It came off the smoker too hot, or the pan sear ran long. 125°F is the handoff and the sear is a minute or two, not five.
No crust formed
The pan was not hot enough or the surface was damp. Dry the tenderloin after the smoke phase and get the pan properly screaming.
It curled as it cooked
The silverskin was left on. Slide a thin knife under it and strip it off before seasoning.
One end was overdone
The thin tail. Tuck it under and tie it, or accept that end will be more done and serve it to whoever prefers that.
It tastes over-smoked
Mesquite rub plus a strong wood. Maple is the right pairing here — if you used hickory or mesquite pellets too, that is likely the cause.

Ways to change it up

Sear on the grill instead
Rake the coals together or crank a gas grill and sear over live fire. More char, slightly less even crust than a pan.
Butter baste the sear
Add butter, garlic and thyme once the crust has formed and spoon it over. Adds richness a very lean cut lacks.
Bacon-wrapped
Wrap before smoking. The bacon bastes the tenderloin as it renders — real insurance on a lean cut.
Different glaze
Honey mustard or a BBQ sauce brushed on after the sear, off the heat, so nothing burns.
Straight smoke, no sear
Take it to 145°F on the smoker alone. Softer crust, more smoke, and considerably more forgiving.

What to serve it with

  • Sliced into medallions so the smoke ring shows.
  • 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 cold cider.

Storage & reheating

Sliced pork tenderloin keeps 3–4 days refrigerated. Store it as a whole piece and slice as you go if you can — whole meat dries out far more slowly than slices.

Because it is lean and was pulled at 145°F, reheating pushes it past where it should be. Warm slices gently in a covered pan with a splash of stock, or use them cold in sandwiches and salads, which is honestly the better outcome.

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

FAQ

What is a reverse sear and why use it on tenderloin?

You cook the meat gently first and sear at the end, rather than the other way round. The slow phase brings the interior up evenly with no grey band under the crust, and it gives the tenderloin time to take on smoke. The sear then builds the crust in a minute or two.

Why pull at 125°F when the target is 145°F?

Because a screaming pan adds roughly 20°F on a piece this size. Pulling at your target temperature means finishing well past it — and on the leanest cut on the pig, that is the difference between juicy and dry.

What temperature should pork tenderloin be cooked to?

Pull it at 145°F and rest. That is the USDA safe temperature for whole-muscle pork and it leaves the centre slightly pink, which is correct and safe. The old advice to cook pork to 160°F or beyond predates modern pork farming and is why tenderloin has a dry reputation.

Is pork tenderloin the same as pork loin?

No, and they are not interchangeable. Tenderloin is a small, thin muscle about a pound that cooks in under an hour. Pork loin is a much larger roast that takes considerably longer. Using loin timings on a tenderloin will ruin it.

Do I need a wireless thermometer?

It makes this method much easier. The whole approach hinges on catching 125°F, and on a pellet grill every lid opening costs several minutes of temperature recovery. A leave-in probe means you watch the number without ever opening the grill.

Why layer two rubs?

Depth. An all-purpose seasoning provides the salt and savoury base, and the mesquite rub adds a smoky top note. On a mild cut like tenderloin that layering gives more dimension than either rub used alone, without either dominating.

Know your cook

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.
