  • 6 cups prepared mashed potatoes OR 6 large russet potatoes, peeled and chopped
  • 8 ounces cream cheese, softened reduced fat is okay

  • 2 teaspoons salt
  • 1/2 teaspoon black pepper
  • Instructions

  • Preheat oven to 350 degrees and grease a 2-quart baking dish.
  • If using prepared mashed potatoes, move ahead to step 3. If using russet potatoes, place potatoes in a large pot, cover with water, cover the pot and bring to a boil. Cook for 20-25 minutes until potatoes are very tender, drain the pot. Transfer potatoes to a large bowl and mash until smooth.
  • Combine potatoes with cream cheese, sour cream, half cup shredded cheese, onion powder, garlic powder (if using), salt, and pepper and mash/mix everything til combined and smooth.
  • Spoon potatoes into prepared baking dish. Top with remaining cheese.
  • Cover the baking dish and cook for 35-40 minutes. Switch to BROIL for 3-5 minutes longer (watch closely so the cheese doesn’t burn). Allow to cool slightly before serving.
