Method
 

Prep and mix
  1. Preheat the oven to 350F and grease a 9x13-inch baking dish.
  2. In a mixing bowl, combine sour cream, cream of chicken soup, melted butter, mayonnaise, diced pimentos, 2 cups cheddar, grated onion, salt, black pepper, and cayenne pepper.
  3. Fold in the thawed hash browns until evenly coated.
  4. Spread the mixture evenly into the greased baking dish and top with the remaining cheddar.
Bake and rest
  1. Bake for 50-55 minutes at 350F until golden and bubbling at the edges.
  2. Rest for 10 minutes before serving to set the creamy casserole.

Notes

For the thickest, scoopable texture, use hash browns that are fully thawed and not watery, and keep the bake time in the 50–55 minute window so the edges bubble but the center stays creamy. Store leftovers covered in the refrigerator up to 4 days; reheat in the oven or microwave until hot. Freeze is not recommended because the dairy may break after thawing. For a lighter option, swap sour cream for a plain low-fat Greek yogurt and use reduced-fat cheddar (it will be slightly softer but still bake well).
