When you want mashed potatoes with depth and smoke, don’t overlook your pellet grill. These Traeger Roasted Garlic Mashed Potatoes combine wood-fired roasted garlic, rich dairy, and a touch of smoke for the creamiest, most flavorful mashed potatoes you’ll make at home. They’re a perfect side for roasts, turkey, pork, or any main you want to elevate.

Traeger Roasted Garlic Mashed Potatoes Recipe
Mashed potatoes are often the highlight of a meal — done well, they can steal the show. Done poorly, they can disappoint even the best main course. This Traeger version aims for silky creaminess with a little texture, smoky aromatics from roasted confit garlic, and rich layers of butter, smoked cream cheese, and sour cream.
The goal here is to keep some bite so the potatoes aren’t baby-food smooth, while still remaining luxuriously creamy. Smoked cream cheese and roasted garlic add depth, while heavy cream and softened butter create that melt-in-your-mouth mouthfeel. Finishing the dish on a pellet grill adds a subtle wood-fired note that pairs beautifully with roasted meats and hearty mains.

How to Make These Mashed Potatoes
Below is an overview so you can understand the workflow. Full step-by-step instructions and exact ingredient amounts are provided in the recipe card further down.
Recommended shortcuts: if you have smoked roasted garlic cream cheese and smoked garlic confit prepared in advance, use them for the most authentic flavor. If not, regular cream cheese and pan-sautéed or powdered garlic will still deliver excellent results.
- Boil the potatoes: Cook peeled, cubed russets in well-salted water until fork-tender. Drain and return to the pot to evaporate any remaining water over low heat.
- Mash and enrich: Mash the potatoes to your preferred texture and fold in softened butter, smoked cream cheese, heavy cream, roasted garlic, and sour cream. Adjust salt and pepper to taste.
- Finish on the pellet grill: Spread the mashed potatoes into a grill-safe baking dish, smoke at low heat to add a subtle wood-fired flavor, then raise the heat to brown the top and heat through.
- Serve warm: Serve immediately beside your favorite protein for an elevated rustic side dish.

Serve These With
These mashed potatoes pair exceptionally well with beef, pork, poultry, and seafood. They’re especially good with slow-roasted or smoked mains that can stand up to the potatoes’ richness. Popular pairings include pot roast, smoked turkey, prime rib, butter-basted roasts, and smoked pork loin. Use them as the creamy base for gravies and pan sauces.
Recipe Card — Traeger Roasted Garlic Mashed Potatoes
Yield: 12 servings
Prep Time: 10 minutes • Cook Time: 1 hour • Total Time: 1 hour 10 minutes
Ingredients
- 6 pounds russet potatoes, peeled and cut into pieces
- Water, plus 3 tablespoons salt for boiling
- 2 cups butter, softened
- 1 cup smoked cream cheese, softened (or regular cream cheese)
- 1 cup heavy cream
- 6 cloves roasted confit garlic (or roasted garlic cloves)
- 1 cup sour cream
- 2 teaspoons salt, plus more to taste
- 1 teaspoon pepper
Instructions
- Peel and cube the potatoes into evenly sized pieces. Place in a large saucepan, add cold water to cover, and add 3 tablespoons of salt. Bring to a boil and cook until the potatoes are fork-tender, about 15–20 minutes depending on cube size.
- Drain the potatoes well, return the pot to low heat, and stir for 2–3 minutes to evaporate any lingering water. This helps keep the potatoes from becoming gummy.
- Using a potato masher (or ricer for a smoother texture), mash the potatoes to your desired consistency. Add the softened butter, smoked cream cheese, heavy cream, and roasted garlic. Mash and fold until evenly combined. For small chunks and texture, stop mashing earlier.
- Stir in sour cream, then taste and season with the 2 teaspoons of salt and 1 teaspoon of black pepper. Adjust seasoning to your preference.
- Prep a grill-safe baking dish (a 10×13-inch pan works well) with cooking spray or a thin coating of butter. Spread the mashed potatoes evenly in the dish.
- Preheat your pellet grill to 200°F following manufacturer instructions. Place the baking dish on the grill and smoke for 30 minutes to impart a gentle wood-smoke flavor. Increase the grill temperature to 325°F and continue cooking for another 20–30 minutes, or until the top is slightly golden and the potatoes are piping hot through.
- Remove from the grill and let rest a few minutes before serving. Spoon generous portions next to your chosen main course and garnish with chopped chives or parsley if desired.

Tips, Variations, and Storage
- For a smoother texture, push cooked potatoes through a ricer before adding dairy. For a chunkier, rustic mash, use a sturdy masher and stop when you reach the preferred texture.
- If you don’t have smoked cream cheese or confit garlic, substitute regular cream cheese and pan-roasted garlic or 2–3 teaspoons garlic powder. The smoke finish on the grill still adds a pleasant wood-fired note.
- To reheat, place leftovers in a covered dish and warm gently in a 350°F oven until heated through, stirring and adding a splash of cream if needed to restore creaminess.
- Make-ahead: Prepare the mashed potatoes through the point of placing in the baking dish, chill, and then finish on the grill or in the oven when ready to serve.
