Ingredients
  

  • 1 bag 30 oz frozen hash browns, thawed
  • 8 tbsp melted butter
  • 1 can 10 3/4 oz condensed cream of chicken soup
  • 1 small onion chopped
  • 2 cups shredded cheddar cheese divided

  • 1 tsp salt
  • 1/2 tsp pepper
  • Fresh grated potatoes optional substitution
  • Cream of mushroom or cream of celery soup optional
  • Monterey Jack Gruyere, or blended cheeses (optional)
  • Greek yogurt or cream cheese optional substitute for sour cream

Method
 

  1. Preheat oven to 350°F and grease a 9x11-inch baking pan.
  2. In a large bowl, combine onion, 1 cup cheddar cheese, salt, and pepper.
  3. Add sour cream and cream of chicken soup; whisk until smooth.
  4. Fold in thawed hash browns and melted butter until evenly coated.
  5. Transfer mixture to baking pan and top with remaining cheddar cheese.

Notes

Always drain thawed hash browns thoroughly to avoid a watery casserole. Maintain 350°F for consistent cooking and avoid overmixing to preserve potato texture.
