How to Make Mashed Potato Pumpkin Gratin

  1. Preheat oven to 375°F (190°C).
  2. Spray a 1 1/2 to 2-quart gratin or baking dish with cooking spray.
  3. Peel and chop 2 lbs russet potatoes. Mince 2 cloves of garlic.
  4. Boil potatoes and garlic in a large pot of salted water over medium heat for 15-20 minutes, or until tender. Drain well.
  5. Return potatoes to the pot. Cook over low heat for 1 minute, stirring frequently, to evaporate excess moisture.
  6. Mash potatoes until completely smooth.
  7. Stir in 4 oz mascarpone cheese, 1/2 cup heavy cream (half and half), and 2 tablespoons of butter until melted and smooth.
  8. Stir in 1 cup pumpkin puree, 1 teaspoon salt, and 1/2 teaspoon black pepper until well combined.
  9. Pour the mixture into the prepared baking dish.
  10. Sprinkle generously with 1/2 cup grated Gruyère cheese.
  11. Bake for 30-35 minutes, or until heated through and the cheese is golden brown and bubbly.
