Instructions

1. Preheat and Prepare the Dish

Set your oven to 350°F (175°C). Coat a 9×13-inch baking dish with nonstick spray. If the hash browns are still quite frozen, spread them on a sheet pan for 10–15 minutes to finish thawing.

2. Make the Creamy Mixture

In a large bowl, whisk together the condensed cream of chicken soup and sour cream until smooth and blended.

3. Add Cheese and Seasonings

Mix in about 1 1/2 cups of the shredded cheddar, reserving the last 1/2 cup for topping. Add salt and pepper if desired.

4. Combine with the Potatoes

Gently stir in the thawed hash browns, coating them thoroughly. Spread the mixture evenly in your prepared baking dish.

5. Top and Bake

Scatter the remaining 1/2 cup of cheddar cheese over the top. Bake uncovered for 45–55 minutes, or until the casserole is bubbly around the edges and the top is melted and lightly golden.

6. Rest and Serve

Let the casserole sit for about 10 minutes before serving for the best texture.
