Ingredients for Awesome Mashed Potato Casserole

  • Yukon Gold Potatoes
  • 1/2 cup (1 stick) unsalted butter
  • Parmesan Cheese
  • 4 ounces cream cheese, softened
  • 1/4 cup chopped fresh chives
  • 2 cloves garlic, minced
  • Salt and pepper to taste

How to Make Awesome Mashed Potato Casserole

  1. Boil 3 lbs of peeled and quartered russet potatoes in a large pot of salted water until tender but still firm (about 15-20 minutes).
  2. Drain the potatoes thoroughly and return them to the pot. Cook over low heat for 1-2 minutes to dry out any excess moisture.
  3. Add 1/2 cup (1 stick) of softened butter, 2/3 cup of grated Parmesan cheese, 4 ounces of softened cream cheese, 1/4 cup of chopped fresh chives, 2 minced cloves of garlic, salt, and pepper. (Optional: Add 1/2 cup of milk or cream for extra richness).
  4. Mash the potatoes until completely smooth and creamy. You can use a potato masher, electric mixer, or food processor.
  5. Pour the potato mixture into a lightly buttered 9x13 inch casserole dish.
  6. Sprinkle the remaining 1/3 cup of Parmesan cheese evenly over the top.
  7. Bake in a preheated 350°F (175°C) oven for 20-25 minutes, or until golden brown and bubbly.

Chef's Tip for Extra Flavor

Small additions can make a big impact! Try a sprinkle of fresh herbs, a dash of your favorite spice blend, or a squeeze of citrus just before serving to really enhance the flavors of your dish.
