Method
Make the casserole
- Heat the oven to 350°F.
- Grease a 9x13-inch baking dish.
- In a large bowl, stir together the hash browns, cream of chicken soup, sour cream, cheddar, onion, 1/2 cup of the melted butter, salt, and pepper until evenly combined.
- Spread the mixture in the prepared baking dish.
- Bake for 30 minutes.
Add and bake the topping
- Toss the cornflakes with the remaining 4 tablespoons melted butter.
- Scatter the cornflakes evenly over the casserole.
- Bake for 15 to 20 minutes, until the casserole is bubbling around the edges and the topping is golden and crisp.
- Let the casserole rest for 10 minutes before serving.
Notes
For the crispiest topping, add the cornflakes only after the first bake. Refrigerate leftovers in an airtight container for up to 4 days; freezing is not recommended because the sour cream-based casserole can become grainy. For a gluten-free version, use gluten-free cream of chicken soup and cornflakes.
