Ingredients

Scale
  • 30 oz frozen hash browns (shredded style)
  • 10 large eggs, room temperature
  • 1 cup whole milk
  • 2 cups shredded sharp cheddar cheese
  • 1 cup shredded low-moisture mozzarella cheese
  • 4 tablespoons unsalted butter, melted
  • 1 medium yellow onion, finely diced
  • 1 teaspoon garlic powder
  • 1 teaspoon kosher salt
  • ½ teaspoon black pepper, freshly ground
  • ½ teaspoon paprika (smoked or regular)
  • Fresh chives or green onions for garnish (optional)

Instructions

  1. Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or non-stick spray.
  2. Spread frozen hash browns evenly in the prepared dish. Do not thaw.
  3. Drizzle melted butter over hash browns, distributing evenly.
  4. Sprinkle diced onion over hash browns.
  5. In a large mixing bowl, whisk together eggs, milk, garlic powder, salt, pepper, and paprika until smooth and uniform.
  6. Pour egg mixture evenly over hash browns. Tilt dish to spread.
  7. Sprinkle both cheeses evenly over the top. Reserve about ½ cup cheddar for the last 10 minutes if desired.
  8. Bake uncovered for 35 minutes. The top should be golden and edges bubbling. Center should be set (not jiggly).
  9. If top browns too quickly, tent loosely with foil for the last 10 minutes.
  10. Let rest for 5-10 minutes before cutting. Garnish with fresh chives or green onions. Serve warm.

Notes

For make-ahead: Assemble night before, cover, refrigerate. Let sit at room temperature 20 minutes before baking; add 5-10 minutes to bake time. For gluten-free, check hash brown package. For dairy-free, use dairy-free cheese, oat milk, and vegan butter. For a heartier version, add 1 cup cooked sausage, bacon, or ham.
