½ cup
salted butter, melted, plus more for greasing
1 teaspoon
garlic powder
½ teaspoon

1 teaspoon
kosher salt
Freshly cracked black pepper

frozen hash browns, thawed, patted dry
3 cups
grated cheddar cheese
⅓ cup

Minced fresh chives, for serving (optional)
Method
Preheat the oven to 375°F with a rack in the center position. Grease a 9x13-inch baking dish with butter.
In a large bowl, combine the sour cream, heavy cream, butter, garlic powder, onion powder, salt, and pepper.
Add half of the potatoes to the prepared baking dish in an even layer. Top with half of the cheddar cheese and the remaining potatoes. Pour the cream mixture over top and sprinkle with the parmesan and remaining cheddar.
Bake for 45 minutes, or until the potatoes are tender and the cheese is browned.
