This ham and cheese hash brown casserole is a delicious and easy-to-make recipe perfect for breakfast or brunch. It's a simple make-ahead dish that's a must for the holidays or any time you're feeding a crowd.
Heat oven to 350 degrees. Coat a 9x13-inch baking pan with cooking spray and set aside.
Add potatoes, ham, and cheese to a large bowl. Toss to combine and add the mixture to the bottom of the prepared baking dish.
In a large bowl, whisk together eggs, milk, salt, onion powder, garlic powder, and pepper. Pour the mixture over the potatoes, ham, and cheese. Using the back of a spoon or spatula, press everything down, so the egg mixture covers all the ingredients.
Bake casserole for approximately 1 hour, checking at the 50-minute mark. The center should be set, and the edges golden brown.
Remove the casserole and let cool for 10 minutes. Sprinkle on chopped chives, slice and serve.
Notes
How To Thaw Hashbrowns:
Refrigerate overnight: This is the safest and most gentle way to thaw frozen hash browns.
Microwave: This is the quickest way to thaw frozen hash browns. Place them in a microwave-safe dish and cook on high for 2–3 minutes, or until thawed. Be careful not to overcook the hash browns, as they will become mushy.
Drain and pat dry: This method is a good compromise between speed and safety. Place the hash browns in a colander and run cold water over them until they are thawed. Then, pat them dry with paper towels.
To Make Ahead:
Prepare the casserole up to the baking step. Cover and refrigerate overnight. In the morning, let the casserole come to room temperature for 30 minutes before baking.
