How to Make Au Gratin Potatoes

  1. Preheat oven to 325°F (160°C).
  2. Wash and scrub 2 lbs of russet potatoes thoroughly. Do not peel.
  3. Place potatoes in a large pot and cover with cold water. Add 1 teaspoon of salt. Bring to a boil, then reduce heat and simmer for 20-25 minutes, or until a fork easily pierces the potatoes.
  4. Drain potatoes and let cool completely. Once cool, peel and cut into 1/2-inch cubes.
  5. In a large bowl, combine the cubed potatoes with 1/2 cup of heavy cream, 1/2 cup of milk, 1/2 teaspoon of salt, 1/4 teaspoon of black pepper, and 1/2 teaspoon of garlic powder.
  6. In a separate bowl, mix together 1 cup of shredded cheddar cheese, 1/2 cup of shredded Gruyere cheese (or substitute with more cheddar), and 1/4 cup of grated Parmesan cheese.
  7. Pour the potato mixture into a greased 9x13-inch baking dish. Sprinkle the cheese mixture evenly over the top.
  8. Cover the baking dish with foil and bake for 30 minutes.
  9. Remove foil and bake for an additional 15-20 minutes, or until the top is golden brown and bubbly, and the potatoes are tender.
  10. Let stand for 5-10 minutes before serving. Enjoy!
