Step 1

Preheat the oven to 375 degrees Fahrenheit. Generously grease a 9x13-inch baking dish with butter or cooking spray.

Step 2

In a large bowl, mix the thawed hashbrowns, cream of chicken soup, sour cream, melted butter, chopped onion, minced garlic, garlic powder, onion powder, salt, pepper, and 2 cups of shredded Colby Jack cheese until well combined.

Step 3

Spread the mixture evenly into the prepared baking dish. Top with the remaining 1 cup of cheddar cheese.

Step 4

Bake uncovered for 45-55 minutes until hot and bubbly, and the top is lightly golden brown. Let stand for 10 minutes before serving. Garnish with chopped green onions or parsley if desired. Enjoy!
