Smoked Corned Beef Recipe Pellet Grill: Applewood-Infused Tender Slices

I’ve perfected smoking corned beef on a pellet grill, and the results are worth every minute. This method transforms tough brisket into tender, juicy slices with a subtle applewood kiss.

The pellet grill offers precise temperature control, ensuring even cooking without constant attention. A slow smoke at 225°F lets the flavors meld deeply into the meat.

What emerges is corned beef with a delicate smoke profile and that signature pink center. The bark forms a flavorful crust while the inside stays moist and easy to slice.

This technique honors tradition while embracing modern convenience. Serve it with mustard or pickles for a meal that feels special.

Ingredients for Smoked Corned Beef Recipe Pellet Grill

Transform brisket into applewood-kissed tenderness with these precision ingredients for the pellet grill.

The corned beef brisket is non-negotiable—point cut has better marbling for smoking. Costco or local butchers often carry pre-brined options with good fat content. Applewood pellets from Traeger or Pit Boss deliver consistent smoke without overpowering. For the mustard, French’s yellow works perfectly as a binder for the bark. Avoid pre-ground pepper; whole peppercorns cracked just before use release more aroma.

No applewood pellets? Cherry or hickory work in a pinch but adjust smoke intensity. Swap brown sugar for honey or maple syrup if you prefer a different sweetness profile. For a darker bark, add 1 tsp of smoked paprika to the rub. The beef broth can be replaced with water in a pinch, but broth adds depth. Butter can be omitted, but it adds a luxurious finish.

Smoked corned beef keeps beautifully—store wrapped in foil in the fridge for up to 5 days. For longer storage, slice and freeze in portions for up to 3 months. Reheat gently in the broth to maintain moisture and that signature tenderness.

Step-by-Step Instructions for Smoked Corned Beef on Pellet Grill

Achieve perfectly tender results with this tested pellet grill method for corned beef brisket.

Step 1: Prepare the Brisket with Spice Rub

Rinse the 3 lb corned beef brisket under cold water to remove excess brine. Pat it completely dry with paper towels—this ensures the rub adheres properly and promotes bark formation.

In a small bowl, combine the 0.5 cup yellow mustard, 0.25 cup brown sugar, 2 tbsp black peppercorns, 1 tbsp kosher salt, 1 tbsp garlic powder, and 1 tbsp onion powder. The mustard acts as a binder for the spices. Coat the brisket evenly on all sides with this mixture, pressing it into the meat for maximum adhesion.

Let the seasoned brisket sit at room temperature for 30-45 minutes while you prepare the pellet grill. This allows the surface to dry slightly, which improves smoke absorption during cooking.

Step 2: Set Up the Pellet Grill for Low and Slow

Fill your pellet grill hopper with the 2 cups applewood pellets. Preheat the grill to 225°F using the smoke setting if available. Applewood provides a mild, sweet smoke that complements the corned beef without overpowering it.

Place a disposable aluminum pan on the grill grates beneath where the brisket will cook. Add the 1 cup beef broth and 0.25 cup apple cider vinegar to the pan. This liquid will catch drippings and create a moist environment, while the vinegar helps balance the richness of the meat.

Optional: Add the 4 whole fresh thyme sprigs to the liquid for an aromatic touch. The thyme will infuse the steam with subtle herbal notes as the brisket cooks.

Step 3: Smoke the Brisket to Perfection

Place the seasoned brisket directly on the grill grates, fat-side up. This position allows the rendering fat to baste the meat naturally as it smokes. Insert a meat probe into the thickest part of the brisket, avoiding the fat cap.

Smoke the brisket undisturbed at 225°F until the internal temperature reaches 165°F. This typically takes 5-6 hours for a 3 lb piece. Resist the urge to check or flip the brisket—every time you open the lid, you lose heat and smoke, which extends the cooking time.

You’ll know it’s ready for the next phase when the bark develops a deep mahogany color and the internal temperature stalls around 165°F. This stall is normal as moisture evaporates from the surface.

Step 4: Wrap and Finish to Tender Doneness

Once the brisket hits 165°F, remove it from the grill and wrap it tightly in pink butcher paper or heavy-duty aluminum foil. Wrapping at this stage helps power through the stall and keeps the meat moist. Return the wrapped brisket to the grill.

Continue cooking until the internal temperature reaches 200-203°F, which usually takes another 2-3 hours. At this temperature, the tough collagen in the brisket breaks down into gelatin, ensuring the meat becomes fork-tender.

Test for doneness by inserting a probe or fork into the thickest part—it should slide in with little to no resistance, like butter.

Step 5: Rest and Serve with Finishing Touch

Remove the brisket from the grill and let it rest, still wrapped, in a cooler or warm oven (170°F or less) for 1-2 hours. This resting period allows the juices to redistribute throughout the meat, ensuring every slice is moist and flavorful.

Unwrap the brisket and discard the thyme sprigs if used. Slice the brisket against the grain into ¼-inch thick pieces. For an extra layer of richness, brush the sliced meat with melted 0.5 cup butter just before serving.

The result should be tender slices with a beautifully smoked bark and juicy interior. Serve immediately with your favorite sides.

Storing and Reheating Leftovers

Refrigerator Storage

Let your smoked corned beef cool to room temperature (about 2 hours) before storing. I use New Seasons Market butcher paper to wrap mine, then place it in an airtight container. It’ll stay fresh in the fridge for up to 5 days. ❄️

Freezer Storage

For longer storage, slice the brisket and wrap portions tightly in heavy-duty foil or freezer bags. Squeeze out excess air to prevent freezer burn. It’ll keep beautifully for up to 3 months—perfect for meal prep.

Stovetop Reheating

Place slices in a pot with ½ cup beef broth and heat over medium-low heat for 10-15 minutes. This method keeps the meat moist and enhances the smoky flavor. I often add a splash of apple cider vinegar for brightness.

Oven Reheating

Wrap the corned beef in foil with ¼ cup broth and warm at 325°F for 20-25 minutes. This gently restores the tender texture without drying it out. It’s my go-to for Sunday leftovers. 🔥

Microwave Reheating

For quick lunches, place slices on a microwave-safe plate and cover with a damp paper towel. Heat on 50% power in 1-minute bursts, checking between each. This prevents the meat from becoming tough.
