Smoked Potatoes Au Gratin
  • 3 large russet potatoes or 4 medium, scrubbed clean
  • 2 tbsp butter, melted
  • 2 cups heavy cream
  • 2 tbsp flour
  • 1-1/2 tsp garlic powder or 2 cloves garlic, finely minced
  • 1/2 tsp onion powder

  • Black pepper to taste
  • 2 cups medium cheddar cheese
  • Prep Time: 30 minutes
  • Cook Time: 1.5-2 hours
  • Skill Level: Easy
  • 6 generous servings


  1. Light cooker according to instructions. We recommend opening up the intake all the way to let the cooker get extra hot. The top thermometer should read at least 300 degrees. For a more smoky flavor, add a few chunks of wood to the lit charcoal.
  2. While the cooker is heating up, start by thinly slicing the potatoes as uniformly as possible.
