Ingredients

  

Casserole Base

• 1 package frozen shredded hash browns 30-ounce, thawed
• 1/2 cup unsalted butter 1 stick, melted, plus extra for greasing
• 1 can condensed cream of chicken soup 10.5-ounce
• 1 container sour cream 16-ounce
• 1/2 cup yellow onion finely chopped
• 1 tsp salt
• 1/2 tsp black pepper
• 2 cups shredded sharp cheddar cheese divided

Topping

• 1 1/2 cups cornflakes crushed, optional for topping

Instructions

 

• Preheat your oven to 350 degrees F (175 degrees C). Lightly grease a 9×13-inch baking dish with butter or cooking spray, ensuring all surfaces are covered to prevent sticking.
• Make sure your frozen shredded hash browns are fully thawed. If they are still frozen, you can rinse them under cold water in a colander and squeeze out excess moisture thoroughly, or let them sit at room temperature for about 30 minutes. This step is crucial for achieving the correct casserole texture.
• In a large mixing bowl, combine the condensed cream of chicken soup, sour cream, melted unsalted butter, finely chopped yellow onion, salt, and black pepper. Stir vigorously with a whisk or spatula until all the ingredients are well incorporated and the mixture appears smooth.
• Add the thawed shredded hash browns and 1 cup of the shredded sharp cheddar cheese to the soup mixture. Gently fold with a sturdy spatula until the hash browns are evenly coated with the creamy mixture and the cheese is distributed throughout.
• Carefully pour the entire hash brown mixture into the prepared 9×13-inch baking dish. Use the back of a spoon or a spatula to spread the mixture evenly into a single layer.
• Sprinkle the remaining 1 cup of shredded sharp cheddar cheese evenly over the top of the hash brown mixture. If you desire a crispy topping, evenly scatter the crushed cornflakes over the cheese layer.
• Bake in the preheated oven for 45 to 60 minutes. The casserole is ready when it is hot and bubbly around the edges, and the cheese and cornflake topping (if used) are golden brown and crisp.
• Remove the casserole from the oven and let it rest on a wire rack for 10 to 15 minutes before serving. This brief resting period allows the casserole to set slightly, making it easier to scoop and ensuring it holds its shape.

Notes

Ensure hash browns are fully thawed to achieve the correct texture. Letting the casserole rest before serving makes it easier to scoop.

Ways to Customize Your Hashbrown Bake

• Extra Cheesy Version: Add a cup of Monterey Jack or pepper jack cheese for more complexity.
• Protein Boost: Mix in cooked diced ham or crumbled bacon for a heartier dish.
• Vegetarian Option: Use cream of mushroom soup instead of chicken for a meat free version.

My Favorite Tips for Hashbrown Casserole Success

• Thaw Thoroughly: Ensure hash browns are completely thawed and dried to avoid watery results.
• Even Coating: Mix gently but thoroughly so every shred gets creamy coverage.
• Golden Brown Test: Bake until edges bubble and top turns golden brown for perfect doneness.
• Resting Time: Let it set for 15 minutes before serving for cleaner slices, similar to my garlic mashed potatoes method.

How to Keep Your Hashbrown Casserole Fresh

• Store: Refrigerate in an airtight container for up to 4 days, covering tightly with plastic wrap.
• Freeze: Wrap entire dish or portions tightly and freeze for up to 3 months before thawing overnight.
• Reheat: Warm in a 350°F oven for 15-20 minutes until heated through, covering if browning too quickly.
• Make Ahead Tip: Assemble the night before and refrigerate, then add 10-15 minutes to baking time.
