1 (32 ounce) package frozen hash brown potatoes, thawed
1 (16 ounce) container sour cream
8 slices cooked bacon, crumbled
1 (1 ounce) package ranch dressing mix
2 cups shredded Cheddar cheese, divided, or more to taste
Preheat oven to 350 degrees F (175 degrees C). Grease a 13X9-inch baking pan with cooking spray or butter.
Combine hash browns, sour cream, bacon, ranch mix, and 1 cup Cheddar cheese in a large bowl; stir until well mixed.
Spread into baking pan; cover with aluminum foil.
Bake in the preheated oven for 45 minutes. Remove foil; sprinkle remaining Cheddar cheese evenly across potatoes. Bake until cheese is bubble and lightly browned around the edges, about 15 minutes.
