How to Smoke a Brisket on a Pellet Grill

Here is how to smoke a brisket on a pellet grill: trim and season a whole packer brisket, cook it fat side down at a low setting until a dark bark forms, wrap it in foil or butcher paper to get through the stall, then keep cooking until a probe or fork slides in with little resistance. Rest it, still wrapped, and slice it against the grain. The pellet grill maker recipes reviewed here agree on that order but not on the numbers, so this guide puts their smoker settings, wrap points and finish temperatures side by side and explains what each step does.

Propane and charcoal grills are for outdoor use only (NFPA), and no grill should be used inside a home, garage or camper because of the risk of carbon monoxide poisoning (CDC); for pellet and wood-fired models, follow your manual.

Food-safety note: the internal temperatures quoted in this guide are tenderness cues taken from manufacturer recipes. They are not food-safety minimums. Use a food thermometer and check the USDA FSIS safe minimum internal temperature chart for the safe temperature and any rest time for beef.

What You Need Before You Start

The Alabama Cooperative Extension System recommends two kinds of thermometer for smoking: an oven-safe thermometer that reads the air temperature inside the smoker, and an internal thermometer that checks the meat before it comes off the heat. A pellet grill’s controller display and built-in meat probe, if your model has one, can serve those roles; either way, plan to have a probe in the meat for every phase of this cook.

• A whole packer brisket. Traeger’s brisket recipe uses a 12 to 14 lb packer; the Pit Boss Classic Smoked Brisket recipe uses a 10 lb brisket.
• Dry pellets and a full hopper. Traeger’s recipe calls for hickory. Check the hopper before you start, because the cook runs for many hours.
• Heavy-duty aluminum foil or butcher paper for the wrap.
• An old towel and a clean, empty cooler if you plan to use the cooler rest described in the Pit Boss recipes.
• A long slicing knife and a large cutting board with room for both muscles.

Step 1: Choose and Trim the Brisket

A full packer brisket has two muscles. Traeger’s recipe notes that the flat is leaner and better for slicing, while the point is fattier and better for shredding or burnt ends. Because one cut holds both a lean and a fatty muscle, the recipes below rely on internal temperature and feel rather than a fixed timetable.

The Pit Boss Barbecue Beef Brisket recipe says to trim the surface fat with a sharp knife the night before cooking, leaving about 1/8 to 1/4 inch of fat. Traeger’s recipe also starts from a trimmed packer but does not give a thickness.

Step 2: Thaw and Season Ahead of Time

Start with a fully thawed brisket. The Alabama extension guidance says to thaw meat in the refrigerator and explains why: smoking cooks at low temperatures, so frozen meat would stay in the temperature danger zone too long before reaching a safe internal temperature. A large packer needs a long time to thaw in the refrigerator, so build that into your schedule.

Season generously on all sides. Traeger’s recipe coats the brisket with a beef rub, wraps it in plastic wrap, and refrigerates it for 12 to 24 hours. Pit Boss seasons the meat side first, then the fat side, covers the brisket, and refrigerates it overnight. If you use a liquid marinade or injection instead, the same extension page says to marinate in the refrigerator, never at room temperature.

Step 3: Set Up and Preheat the Pellet Grill

Clean before you light. The Pit Boss recipe says to clean the grates and grease tray and make sure the firepot is clean. Then check your pellets. On its pellet storage page, Traeger says poor pellet quality, often caused by poor storage, is the No. 1 cause of temperature issues, and that moisture can make pellets crumbly enough to clog the auger or fail to ignite. On a cook this long, a pellet problem late at night is hard to recover from, so start with dry pellets that snap cleanly.

Set the temperature. The makers do not agree on one number:

• Traeger’s recipe sets the grill to 225°F and preheats with the lid closed for 15 minutes.
• Pit Boss’s Classic Smoked Brisket also starts at 225°F.
• Pit Boss’s Barbecue Beef Brisket preheats to 250°F and waits for the grill to settle before the meat goes on.
• Traeger’s wrapping guide notes that Traeger pro Matt Pittman keeps his grill at 275°F for the entire cook.

All four settings sit inside the range the Alabama extension guidance gives for smoker air temperature: hold it between 225°F and 300°F throughout the cooking process. A lower setting gives more time for smoke and bark; a higher one shortens the day. For a first brisket, 225 to 250°F follows the published recipes most closely.

Step 4: Smoke Until the Bark Sets

Place the brisket directly on the grates, fat side down, as both the Traeger and Pit Boss recipes do, and close the lid. Traeger inserts the probe into the thickest part of the meat at the start. The Pit Boss Barbecue Beef Brisket recipe waits 4 hours, then inserts the probe into the fat seam between the point and the flat so the tip sits in the center of that seam.

This first phase builds the bark, the dark crust on the surface. Traeger’s wrapping guide describes the goal as a mahogany-colored crust and says most of the smoke flavor gets into the meat during the first few hours of cooking. The recipes give these first-phase targets:

• Traeger: about 6 hours at 225°F to reach 160°F internal.
• Pit Boss Classic: about 3 to 5 hours at 225°F to reach 150 to 160°F.
• Pit Boss Barbecue Beef Brisket: 4 hours at 250°F, then about 2 more hours with the probe in, wrapping at 150 to 160°F.

The Stall and When to Wrap Brisket on a Pellet Grill

Somewhere in the middle of the cook, the internal temperature stops climbing. Traeger’s wrapping guide says this happens when the meat nears 165°F, attributes it to evaporation cooling the surface, and says it can last as long as six hours. Wrapping traps the moisture so evaporative cooling stops and the temperature starts rising again.

The recipes disagree on the exact wrap point, so here they are in parallel:

A practical reading of the table: start watching the bark at about 150°F and wrap when its color and firmness are where you want them, which in these recipes falls between 150 and 170°F. Wrapping earlier gets you through the stall sooner; wrapping later gives the bark more time to firm up.

Wrapping in foil

Traeger’s wrapping guide calls foil the original “Texas Crutch” and suggests it for beginners because it is easy to seal tightly. It describes laying two arm-length sheets of heavy-duty foil on top of each other, setting the brisket on them, and wrapping as tightly as you can. The tight seal speeds the cook, but the guide warns that it also makes the bark moist and softer. Pit Boss’s Barbecue Beef Brisket recipe uses foil too: it seals the brisket on three sides, runs the probe wire between the sheets, pours in a can of beef consommé, closes the last side, and sets the package on an extra sheet of foil so it does not stick to the grate and tear.

Wrapping in butcher paper

According to Traeger’s guide, butcher paper speeds the cook like foil does but lets some smoke through, and wrapping with it takes practice to get right. Choose paper if you care more about bark texture than about the easiest wrap.

Not wrapping

You can leave the brisket unwrapped for the whole cook. Traeger lists three trade-offs of wrapping: slightly less smoke flavor, a softer bark, and a higher risk of overcooking because the temperature can rise quickly once wrapped. Skipping the wrap avoids those, but you sit through the full stall, so plan extra hours.

Step 5: Finish by Feel, Not by the Clock

After wrapping, the brisket goes back on the grill until it is tender. Here the published numbers spread the most: Pit Boss Classic pulls at 192°F, Pit Boss Barbecue Beef Brisket checks at 200°F and allows up to 205°F, Traeger’s recipe goes to 204°F, and Traeger’s wrapping guide says around 203°F. These are tenderness targets, not food-safety thresholds. For the safe minimum internal temperature and any rest time for beef, check the USDA FSIS chart.

Because the numbers vary, the recipes also tell you how to judge tenderness by feel:

• Traeger’s wrapping guide says to cook to temperature, not time, and warns that following recipe timing instead of a thermometer is how beginners end up with overcooked, mushy brisket. It suggests checking the meat temperature at least every 30 minutes after wrapping, then every 15 minutes once it reads 190°F.
• Pit Boss’s Barbecue Beef Brisket recipe opens the foil at 200°F and pushes a dinner fork into the flat. If it goes in and out “like a hot knife through butter,” the brisket is done. If there is much resistance, reseal the foil, cook to 205°F, and check again.

Check the flat as well as the point. Traeger describes the flat as the leaner muscle, and Pit Boss does its fork check in the flat.

Step 6: Rest, Then Slice Against the Grain

Do not slice straight off the grill. Traeger’s recipe rests the brisket in its foil for at least 30 minutes. Both Pit Boss recipes go longer: wrap the foiled brisket in a clean towel, place it in a small clean cooler, and rest it for at least 2 hours. The Pit Boss Classic recipe adds that the longer the brisket rests, the more moisture it keeps when you carve. If you unwrapped to re-crisp the bark, Traeger’s guide notes the brisket will cool quickly but stays tender as long as it reached its finish temperature first; it suggests about 225°F for that unwrapped re-crisp.

To slice, follow the Pit Boss method:

1. Lift the brisket out of the foil and save the liquid.
2. Separate the point from the flat by running the knife along the fat seam between them.
3. Slice the flat across the grain into slices just thick enough to hold together.
4. Cut the point into 1/2 inch cubes by slicing across the grain first, then with the grain.
5. Pour some of the reserved foil liquid over the slices and cubes.

Storing Leftovers

A whole packer usually leaves leftovers. The Alabama extension guidance says to store leftovers within two hours, or within one hour if the air temperature is above 90°F. Divide them into small portions in shallow containers, and refrigerate them or pack them in a cooler with ice or gel packs.

Common Problems and Fixes

• Grill temperature swings or the fire goes out. Start with Traeger’s top cause, the pellets. If they are crumbly, dull, or there is a lot of clumped sawdust, Traeger says moisture may have compromised them. Its pellet storage page advises keeping pellets dry and airtight and emptying the hopper before prolonged rain or high humidity.
• The temperature has not moved for hours. That is the stall, not a broken probe. Wrap to push through it, or wait it out if you want an unwrapped bark.
• The bark turned soft. Foil traps moisture. Switch to butcher paper next time, wrap later, or briefly unwrap at the end as Traeger’s guide describes.
• The flat is dry and crumbly. Traeger’s guide connects overcooking to following the clock instead of the thermometer. Check more often after 190°F and confirm with a probe or fork.
• The brisket went into the smoker partly frozen. Avoid this entirely; the extension guidance says to thaw in the refrigerator first because of the low cooking temperatures.

When This Method Is Not the Right Fit

A whole packer on a pellet grill rewards patience, and it is not for every situation:

• Skip it for a fixed dinner time with no slack. The recipes list 8 to 12 hours of cooking plus a rest of 30 minutes to 2 hours or more, and the stall alone can add hours. Start early enough that the long rest in the Pit Boss recipes fits before you serve.
• Skip foil if a firm bark is your priority. Use butcher paper or no wrap and accept a longer cook.
• Do not start with damp pellets. Traeger links moisture-damaged pellets to clogged augers and failed ignition, which matters most on an overnight or all-day cook.

FAQ

What temperature should I smoke a brisket at on a pellet grill?

The maker recipes reviewed here use 225°F (Traeger, Pit Boss Classic) or 250°F (Pit Boss Barbecue Beef Brisket), and Traeger notes one pitmaster who runs 275°F. The Alabama extension guidance says to keep smoker air between 225°F and 300°F throughout the cook.

When should I wrap a brisket on a pellet grill?

Wrap once the bark has the color and firmness you want. The recipes compared here wrap between 150 and 170°F internal: Pit Boss at 150 to 160°F, Traeger’s recipe at 160°F, and Traeger’s wrapping guide at 165 to 170°F.

How long does it take to smoke a brisket on a pellet grill?

Traeger’s recipe lists a 12-hour cook for a 12 to 14 lb packer, and the Pit Boss recipes list 8 to 10 hours, before resting. Every brisket is different, so cook to temperature and tenderness, not to the clock.

Should I use foil or butcher paper?

Foil is easier to seal and speeds the cook, but it softens the bark; Traeger suggests it for beginners. Butcher paper lets some smoke through and keeps the bark firmer, but it takes practice to wrap well.

At what internal temperature is brisket done?

For tenderness, the recipes pull brisket between 192°F and 205°F and confirm with a probe or fork that slides in with little resistance. Those are tenderness cues, not food-safety minimums. Check the USDA FSIS safe minimum internal temperature chart for the safe temperature and any rest time for beef.

How long should brisket rest?

Traeger rests it in foil for at least 30 minutes. Pit Boss wraps the foiled brisket in a towel and rests it in a cooler for at least 2 hours, noting that a longer rest keeps more moisture in the meat. These recipe rests are about moisture and slicing, not food safety.

The sequence is simple: trim, season ahead, smoke low until the bark sets, wrap through the stall, finish by tenderness, and rest before slicing. Where the makers disagree on numbers, keep your grill between 225 and 300°F, wrap somewhere between 150 and 170°F, and let a probe or fork, not a timer, tell you when the brisket is ready.
