How to Make the Recipe
Step 1: Prep the Roast
Start by trimming any excess fat from the beef chuck roast, if needed. Season the roast on all sides with salt, paprika, onion powder, black pepper, and granulated garlic. This will form a flavorful crust as it cooks.
Step 2: Set Up the Traeger Grill
Preheat your Traeger grill to 225°F (107°C). If you’re using wood pellets, hickory or oak work well for this recipe, but any wood will give the roast a nice smoky flavor.
Step 3: Assemble the Roast
Place the seasoned chuck roast on the grill grate. Add the chopped carrots around the roast, then pour the water into the bottom of the roasting pan or a foil-lined tray. Place the stick of butter on top of the roast.
Step 4: Add the Flavorings
Sprinkle the au jus mix, ranch dressing mix, and granulated garlic over the roast. Place the whole pepperoncini peppers around the roast. Don’t worry if the peppers look a little too spicy—while they do bring some heat, they also add a tangy flavor that balances perfectly with the richness of the beef.
Step 5: Slow Cook the Roast
Close the lid of the Traeger and let the roast cook low and slow for 4-5 hours, or until the meat is fork-tender and pulls apart easily. The Traeger smoker ensures that the roast will stay juicy and flavorful throughout the cooking process.
Step 6: Shred and Serve
Once the roast is done, remove it from the grill and transfer it to a cutting board. Shred the meat with two forks and mix it with the juices and vegetables. Serve the pot roast with its rich gravy over mashed potatoes, rice, or bread for a comforting meal.

Tips for Making the Recipe
- Rest the Roast: Let the roast rest for 10-15 minutes after cooking before shredding to lock in the juices.
- Add More Liquid if Needed: If the roast looks too dry, add more water or beef broth during cooking to maintain a moist environment for the meat.
- Watch the Temperature: The key to a tender pot roast is low and slow cooking. Keep the temperature consistent on your Traeger for the best results.
- Don’t Skip the Butter: The butter helps create a rich, flavorful gravy that’s the highlight of the dish. Make sure to leave it on top of the roast as it cooks.
- Keep It Simple: The beauty of this recipe lies in its simplicity. Don’t worry about overcomplicating the flavors—let the Traeger do the work for you!
