Bacon-wrapped pork tenderloin comes off the smoker with a mahogany crust, salty edges of crisp bacon, and a center that stays juicy instead of drying out. The sweet-spiced rub melts into the bacon fat as it cooks, so every slice tastes smoky, savory, and just a little caramelized around the outside.
The trick is steady low heat and patience. Pork tenderloin is lean, which means it can go from perfect to dry fast if you rush it, but wrapping it in bacon gives it a little protection while the pellet grill does the work. A light brown sugar rub helps the bacon brown without burning, and the final internal temperature matters more than the clock.
Below, I’ll show you how to keep the bacon on, how to tell when the tenderloin is done, and what to change if you want a little more smoke or a different seasoning angle.
The bacon stayed on, the rub turned into this perfect little crust, and the tenderloin was still juicy at 145. I let it rest the full 10 minutes and the slices held together beautifully.
Save this pellet grill smoked bacon wrapped pork tenderloin for the next time you want smoky pork with crisp bacon and a juicy center.
The Bacon Trap Most Smoked Tenderloins Fall Into
Pork tenderloin doesn’t need much time on the smoker, and that’s where a lot of cooks get into trouble. The bacon wants longer than the pork does, so if you chase crispy bacon by pushing the cook too far, the tenderloin dries out before the wrap is where you want it. This version works because the rub starts the browning, the bacon overlaps just enough to stay put, and the grill sits low enough that the pork can come up to 145°F without rushing.
The other mistake is cutting too soon. Pork tenderloin looks done the moment it comes off the heat, but the juices need a few minutes to settle back into the meat. Slice it right away and those juices run onto the board instead of staying in the meat where they belong.
What the Rub and Bacon Are Doing Here
- Pork tenderloin — This cut stays lean and tender if you stop at 145°F. Don’t swap in pork loin and expect the same timing; a loin is thicker and needs a different cook, or the bacon will finish long before the center does.
- Bacon — Regular sliced bacon wraps better than thick-cut here because it firms up in the same window the pork finishes. Thick-cut bacon can stay floppy unless you extend the cook, which pushes the tenderloin past its best texture.
- Brown sugar — This helps the bark darken and gives the bacon a glossy edge. Light or dark brown sugar both work, but dark brown sugar brings a deeper molasses note and can brown a little faster.
- Paprika, garlic powder, and onion powder — This is the backbone of the rub. Smoked paprika adds a little extra smoke if your pellets are mild, and garlic plus onion give the pork a savory base that balances the bacon.
- Salt and pepper — Pork tenderloin needs enough salt to taste seasoned all the way through, not just on the surface. Season the rub generously so the bacon and pork both pull from the same seasoning mix.
Building the Wrap So the Bacon Stays Put
Mix and Season First
Stir the brown sugar, paprika, garlic powder, onion powder, salt, and pepper together before you touch the meat. That keeps the seasoning even, and it helps the sugar distribute instead of clumping in one spot. Rub it over every side of the tenderloins, pressing it on so it sticks. If the surface looks dusty instead of coated, go back and work the rub in with your hands.
Wrap With Slight Overlap
Lay the bacon slices over the pork with a small overlap so the seams hold together as the fat renders. Start at one end and spiral around the tenderloin so there are no big gaps. If the bacon wants to slide, the tenderloin was probably too wet; pat it dry before seasoning, and the wrap will behave better on the grill.
Smoke at 225°F Until the Center Hits 145°F
Set the pellet grill for steady indirect heat with apple or hickory pellets. Put the tenderloins on the grate and let them smoke for 60 to 90 minutes, depending on thickness. The real target is temperature, not time: pull them when the center reaches 145°F. If the bacon isn’t as crisp as you want at that point, give it a few extra minutes, but watch closely so the pork doesn’t overshoot.
Rest Before Slicing
Let the tenderloins sit for 10 minutes before you cut them. That short rest is what keeps the slices juicy and helps the bacon stay attached when you move them to the board. Use a sharp knife and slice across the grain so each piece stays tender and the smoky bacon wrap shows off cleanly.
How to Adapt This for Different Smokers and Diets
Make It a Little Spicier
Add 1/2 teaspoon cayenne or chipotle powder to the rub. That gives the sweet bacon a sharper edge and works especially well if you’re serving the pork with creamy sides or baked beans.
Use Turkey Bacon for a Lighter Version
Turkey bacon can work, but it won’t render the same way or crisp around the pork the same way pork bacon does. Brush it lightly with oil before wrapping and expect a softer finish with less of that classic smoky bacon texture.
Try Maple Instead of Brown Sugar
A small drizzle of maple syrup in place of some of the brown sugar gives the rub a rounder sweetness and a deeper glaze on the bacon. Use just enough to coat; too much turns sticky before the pork has time to smoke properly.
Storage and Reheating
- Refrigerator: Store leftovers in an airtight container for up to 4 days. The bacon softens a bit in the fridge, but the pork stays tender if you don’t overcook it the first time.
- Freezer: Freeze sliced portions for up to 2 months. Wrap tightly and thaw in the fridge so the bacon and pork warm evenly instead of drying out at the edges.
- Reheating: Reheat covered in a 300°F oven until just warmed through. The common mistake is blasting it in the microwave, which toughens the pork and turns the bacon rubbery.

Ingredients
Equipment
Method
- In a small bowl, mix brown sugar, paprika, garlic powder, onion powder, salt, and pepper until evenly combined. The mixture should look like a uniform, speckled rub.
- Rub the spice mixture all over the pork tenderloins, pressing lightly so it adheres. Cover every surface so the seasoning creates a flavorful crust under the bacon.
- Wrap each tenderloin with the bacon slices, overlapping slightly as you go. Arrange the bacon so it fully covers the tenderloin and stays snug.
- Preheat your pellet grill to 225°F using apple or hickory pellets. Wait until the grill is stable at temperature before adding the meat.
- Place the bacon-wrapped tenderloins on the grill and smoke for 60 to 90 minutes. Cook until the internal temperature reaches 145°F, and smoke should be visible throughout.
- Remove the tenderloins from the grill and rest for 10 minutes before slicing. The bacon should look set and slightly crisp as the juices redistribute.
- Slice the tenderloins into medallions and serve immediately. The interior should show a light pink center at 145°F.
