Step 1

Peel and cut potatoes into cubes. Add to a large saucepan, and cover with water. Boil potatoes until fork-tender, about 15-20 minutes

Step 2

Drain water from potatoes, place the pot back on the stove over low heat and cook for 2-3 minutes continually stirring to cook the remaining excess water out.

Step 3

Using a potato masher, mash the potatoes and add butter, cream cheese, heavy cream, and garlic. Mash until your desired consistency is reached.

Step 4

Add salt and pepper to taste, and fold in sour cream.

Step 5

Spray a grill-safe dish with cooking spray, and spoon the potatoes into the pan and spread evenly. A 10x13 inch baking dish is a good size.

Step 6

Preheat pellet grill to 200°F following to factory directions. Place the potatoes onto the grill, and smoke for 30 minutes. Turn the heat up to 325 and grill for another 20-30 minutes, or until the top is golden brown and everything is piping hot.
