Instructions
 

  • Cook the Potatoes:

  • Assemble the Casserole:
  • Transfer the potato mixture to a greased 9x13-inch casserole dish. Spread evenly with a spatula.
  • Top with Cheese:
  • Sprinkle the remaining 1/2 cup of cheddar cheese over the top of the casserole.
  • Bake:
  • Preheat your oven to 375°F (190°C). Bake the casserole for 20–25 minutes, or until the cheese is melted and golden.
  • Garnish and Serve:
  • Sprinkle with reserved green onions before serving. Serve warm and enjoy!
