Method
- Heat the oven to 350 F. Butter a 9x13 inch baking dish generously, including the corners.
- Spread the thawed hash browns on a clean kitchen towel or a double layer of paper towels and press firmly to pull out the moisture. Wet potatoes make a loose casserole, so take the extra minute here.
- Melt the butter in a small saucepan. Measure out 4 tablespoons for the potato mixture and set the remaining 4 tablespoons aside for the topping.
- In a large bowl, stir together the sour cream, condensed cream of chicken soup, shredded cheddar, 4 tablespoons melted butter, diced onion, salt, and pepper until evenly combined.
- Add the dried hash browns and fold with a rubber spatula until every strand is coated. The mixture will be thick and heavy. Do not overwork it or the potatoes will break down.
- Scrape the mixture into the buttered dish and spread it level, pushing it into the corners. Cover tightly with foil.
- Bake covered for 50 to 60 minutes, until the casserole is hot through and bubbling visibly around the edges. A knife inserted in the center should come out steaming.
- While it bakes, toss the crushed corn flakes with the reserved 4 tablespoons melted butter in a medium bowl until the flakes look glossy and evenly coated.
- Remove the foil and scatter the buttered corn flakes evenly across the surface. Return the dish to the oven uncovered.
- Bake 15 minutes more, until the crust is deep golden and audibly crisp when tapped with a spoon.
- Rest 10 minutes before serving. The casserole firms up as it cools and cuts into clean squares instead of sliding apart.
