How to Make Au Gratin Hash Browns Potatoes

  1. Preheat oven to 350°F (175°C).
  2. Melt butter in a large skillet over medium heat. Add the chopped onion and cook until softened, about 5 minutes.
  3. Add the shredded potatoes, salt, and pepper to the skillet. Cook, stirring occasionally, until the potatoes are tender and lightly browned, about 10-15 minutes.
  4. Stir in the milk (or half-and-half).
  5. Pour the potato mixture into a greased 9x13 inch baking dish.
  6. Sprinkle the cheddar and Parmesan cheese evenly over the top.
  7. Bake for 30-40 minutes, or until the cheese is melted and bubbly and the potatoes are heated through and slightly crispy on top.
  8. Let stand for 5-10 minutes before serving. Enjoy!
