Bacon-wrapped pork tenderloin on a pellet grill gives you the best parts of barbecue without a long ingredient list or a complicated finish. The pork stays tender, the bacon bastes the outside as it renders, and the smoke adds a wood-fired depth that makes every slice feel a little more special than a standard weeknight roast.
The trick is keeping the grill low enough for the bacon to render before the tenderloin dries out. A simple brown sugar and spice rub helps the surface take on color, while the pellet grill does the quiet work of building smoke flavor without blasting the meat with high heat. You end up with crisp-edged bacon, a juicy center, and slices that hold together instead of shredding the second the knife hits them.
Below, I’ve included the timing cues that matter most, plus a few smart swaps and storage notes if you want to work this into your regular rotation.
The bacon crisped up at the edges and the pork stayed pink and juicy all the way through. I pulled it right at 145°F like you said, and it sliced cleanly after resting.
Save this smoked bacon wrapped pork tenderloin for the next time you want a juicy center, smoky edges, and crisp bacon from the pellet grill.
The Bacon Needs Time to Render Before the Pork Dries Out
With bacon-wrapped tenderloin, the biggest mistake is rushing the heat. A hot grill can brown the outside before the bacon has a chance to render, which leaves you with rubbery strips and pork that’s already overcooked by the time the center reaches 145°F. Low-and-slow gives the bacon time to tighten, the fat time to baste the meat, and the smoke time to settle in.
The other thing that matters is how you wrap it. Slight overlap is enough to hold the bacon in place and cover the tenderloin evenly, but you don’t want thick double layers all over the surface. Too much overlap blocks smoke and creates uneven cooking, especially on the ends.
What Each Ingredient Is Doing in the Smoke
- Pork tenderloin — This cut is lean and tender, which is why it works so well with smoke. It cooks fast and slices cleanly, but it also dries out quickly if you overshoot the temperature, so pull it the moment the center hits 145°F.
- Bacon — Thin-cut bacon wraps and renders more evenly than thick-cut here. Thick bacon can stay soft while the pork finishes, so use standard slices if you want better texture and more reliable coverage.
- Brown sugar — It helps the rub cling and gives the bacon and pork a little caramelized edge. Don’t use a heavy hand, though, or the sugar can darken too fast on the grill.
- Paprika, garlic powder, and onion powder — These build the savory backbone of the rub without fighting the smoke. Smoked paprika works if you want a deeper barbecue note, but regular paprika keeps the flavor cleaner.
How to Keep the Bacon Wrapping Tight While the Pork Smokes
Building the Rub
Mix the brown sugar, paprika, garlic powder, onion powder, salt, and pepper into a dry rub, then coat the tenderloins all over. The surface should look evenly seasoned, not caked on, because thick patches of sugar can scorch before the bacon is done. If the rub feels damp or clumpy, break it up with your fingers before it hits the meat.
Wrapping the Tenderloins
Lay the bacon slices over the pork with a slight overlap so they hold together as they cook. Keep the wrap snug, but don’t stretch the bacon hard or it can shrink and pull away in the smoker. If the ends look bare, tuck the tail of a slice underneath instead of adding extra layers on top.
Smoking to Temperature
Preheat the pellet grill to 225°F with apple or hickory pellets, then smoke until the internal temperature reaches 145°F. Start checking early, because tenderloin can move from nearly done to overdone fast. If the bacon needs a little more color at the end, give it a short blast of higher heat for a few minutes, but don’t use that as your main cooking method.
Resting and Slicing
Let the pork rest for 10 minutes before slicing. That pause keeps the juices from running onto the cutting board the second you cut into it. Slice across the grain into thick medallions so the bacon stays attached and the center stays juicy.
Three Ways to Adjust This Pork Tenderloin Without Losing the Smoke
Use maple instead of brown sugar
A small spoonful of maple syrup in the rub gives the pork a rounder sweetness and a slightly stickier exterior. It browns faster than brown sugar, so keep the grill steady and watch the color near the end of the cook.
Make it dairy-free and gluten-free without changing the method
This recipe is naturally dairy-free and gluten-free as written, so the only real job is checking your bacon and seasonings for added fillers. That keeps the texture and smoke exactly the same, which is how a simple pork dish should stay.
Swap in applewood or cherry pellets for a milder smoke
Applewood gives the pork a softer sweetness, while cherry adds a little color and a gentle fruit note. Hickory is stronger and more classic barbecue, so choose the wood based on how pronounced you want the smoke to taste.
Scale it for a crowd
You can smoke the tenderloins side by side as long as air can move around them. Leave space between each one so the bacon sets evenly; crowding the grate traps steam and softens the wrap.
Storage and Reheating
- Refrigerator: Store sliced pork in an airtight container for up to 4 days. The bacon softens a little, but the flavor holds up well.
- Freezer: It freezes well if you wrap the slices tightly and pack them flat. Thaw in the refrigerator so the meat doesn’t lose more moisture than it has to.
- Reheating: Warm gently in a covered skillet over low heat or in a 300°F oven with a splash of broth. High heat dries out tenderloin fast and turns the bacon tough.

Method
- Mix brown sugar, paprika, garlic powder, onion powder, salt, and pepper in a bowl until evenly combined, then set aside. The rub should look uniformly speckled with spices.
- Rub the spice mixture all over the tenderloins, pressing lightly so it adheres. Cover every surface for consistent smoky flavor.
- Wrap each tenderloin with bacon slices, overlapping slightly as you go. The bacon should fully cover the top and sides without large gaps.
- Preheat the pellet grill to 225°F using apple or hickory pellets. Wait until the grill stabilizes so the smoke stays steady.
- Place the bacon-wrapped tenderloins on the grill and close the lid, then smoke for 60 to 90 minutes. Cook until the internal temperature reaches 145°F, and look for bacon that has darkened and tightened around the meat.
- Let the tenderloins rest for 10 minutes before slicing. The juices should settle and the bacon should stay crisp as you cut.
