Bacon-wrapped pork tenderloin comes off the pellet grill with the kind of contrast that keeps it in regular rotation: a smoky, peppery crust, crisped bacon on the outside, and a center that stays juicy instead of drying out. The brown sugar in the rub helps the bacon take on color, but it doesn’t push the meat into candy territory. What you get is a savory-sweet bark with just enough smoke to taste deliberate.
The key is treating the tenderloin gently. Pork tenderloin is lean and cooks fast, so the grill temperature stays low enough to let the bacon render without burning before the pork is done. I also like overlapping the bacon slightly instead of stretching it tight; that gives it a better chance to stay put while it cooks and crisps.
Below, I’ll walk through the one part that matters most: getting the smoke and internal temperature lined up so the pork stays tender and the bacon finishes with real texture. There’s also a quick note on pellet choices and a few ways to adjust the rub if you want a little more heat or a less sweet finish.
The bacon crisped up beautifully and the pork stayed juicy all the way through. I pulled it at 145°F like you said and it sliced clean with that pink center everyone wanted.

Why the Bacon Needs Room to Render, Not Just Time to Cook
The biggest mistake with bacon-wrapped tenderloin is cooking hot enough to brown the bacon before the fat has time to render. That leaves you with streaky, rubbery slices clinging to a pork roast that might already be done underneath. A 225°F pellet grill gives the bacon a chance to tighten, render, and pick up smoke while the pork gently climbs to temperature.
The rub matters here too. Brown sugar and paprika help the outside color without needing a sugary glaze, and the seasoning stays simple enough that the smoke still comes through. If your bacon shrinks loose as it cooks, that usually means it was wrapped too tightly or overlapped too little. Slight overlap is the sweet spot.
What Each Ingredient Is Actually Doing in This Dish
- Pork tenderloins — This cut stays tender when it’s cooked to 145°F and rested. It’s lean, so it doesn’t forgive overcooking the way pork shoulder does. Buy tenderloins that are similar in size so they finish at the same time.
- Bacon — Thin-cut bacon renders faster on the pellet grill and helps the wrap tighten around the pork. Thick-cut bacon can work, but it often needs more time than the tenderloin wants, which is how you end up with under-rendered bacon. If thick-cut is all you have, plan on a little more cook time and watch the internal temperature closely.
- Brown sugar — This helps the exterior caramelize and gives the rub a little stick so it clings to the meat. You don’t need much. Too much sugar on a low-and-slow cook can turn the outside sticky instead of savory.
- Paprika, garlic powder, and onion powder — These build the base of the rub without making it muddy. Paprika supports color and smoke, while garlic and onion keep the pork tasting seasoned from edge to center. Use fresh spices if yours have been hanging around for years; old spices can taste flat after a long cook.
- Apple or hickory pellets — Apple gives a softer, slightly sweeter smoke that fits the bacon well. Hickory is bolder and a little more classic BBQ. Either works, but avoid very aggressive woods that can overpower the pork.
Smoke It Low, Then Pull It Before the Pork Gets Dry
Building the Rub
Mix the brown sugar, paprika, garlic powder, onion powder, salt, and pepper in a small bowl until the color looks even. You want every bite to taste seasoned, not just the surface. Pat the pork tenderloins dry first so the rub sticks instead of sliding off. If the meat is damp, the bacon will grab onto a sloppy layer instead of a seasoned one.
Wrapping the Bacon
Wrap each tenderloin with bacon slices, overlapping them slightly so the seams close up as the bacon shrinks. Start at one end and spiral the strips around the meat with just enough tension to hold them in place. If the bacon pulls too tight, it can split or slide during the cook. A snug wrap that still looks relaxed is what you want.
Managing the Pellet Grill
Preheat the pellet grill to 225°F and give it a few minutes to settle before the pork goes on. Set the tenderloins on the grate and close the lid; every peek costs heat and slows the render. The meat is done when the thickest part hits 145°F, not when the bacon looks perfect, because pork tenderloin dries out fast if you chase a darker exterior. If the bacon needs a little more color after the pork reaches temp, a short blast of higher heat at the end works better than overcooking the meat for the sake of the wrap.
The Rest and Slice
Let the tenderloins rest for 10 minutes before cutting. That pause keeps the juices inside the meat instead of running onto the board. Slice across the grain into thick pieces so the bacon stays attached in neat rounds. If you cut too soon, the center will look good but the juices will flood out and the slices will feel dry by the time they hit the plate.
How to Adjust the Rub, Smoke, and Wrap Without Breaking the Recipe
Make It Spicier
Add a pinch of cayenne or chipotle powder to the rub. That brings heat without changing the cook time, and the smoke from the pellet grill helps round out the sharpness. Keep it light if you still want the bacon and pork to lead the dish.
Use Thick-Cut Bacon
Thick-cut bacon gives you a meatier bite, but it renders slower and can stay soft when the pork is already done. If you use it, expect the tenderloin to stay on the grill closer to the full 90 minutes and check the center early so the pork doesn’t overshoot 145°F.
Dairy-Free and Gluten-Free as Written
This recipe already fits both of those needs without any changes. The only thing to double-check is your bacon and spice labels, since some brands sneak in sugar blends or anti-caking additives. Once those are clear, the recipe stays exactly the same.
Swap the Pellet Wood
Apple pellets give a milder finish, while hickory brings a deeper BBQ edge. Fruitwoods like cherry also work if you want the outside to pick up a little darker color. Stay away from woods that are too intense for a short cook, because tenderloin doesn’t sit on the smoker long enough to balance harsh smoke.
Storage and Reheating
- Refrigerator: Store leftovers for up to 3 days in an airtight container. The bacon softens as it sits, but the pork stays usable for sandwiches, wraps, or quick dinners.
- Freezer: It freezes well if you slice it first and wrap the pieces tightly. Freeze for up to 2 months, then thaw overnight in the refrigerator before reheating.
- Reheating: Reheat gently in a covered skillet over low heat or in a 300°F oven until just warmed through. High heat dries the pork out fast and makes the bacon tough instead of crisp.
