Method
Preparation
- Preheat the oven to 350°F and grease a 9 x 13-inch baking dish with cooking spray.
- In a small bowl, gently toss the crushed cornflakes with the melted butter and set aside.
- Melt the 4 tbsp butter in a skillet over medium heat. Add the finely chopped onion and cook for about 5 minutes until tender and translucent.
- In a large bowl, stir together the cooked onion and its butter, sour cream, cream of chicken soup, and 2 cups of cheddar cheese. Season with salt and pepper, and mix until smooth.
- Gently fold in the thawed hash browns until fully coated in the creamy mixture. Spread the mixture evenly in the prepared baking dish.
- Sprinkle the remaining 1/2 cup cheddar cheese over the top and finish with the buttered cornflake mixture.
Baking
- Bake for 40 to 45 minutes, or until bubbling around the edges and golden brown on top.
- Let the casserole rest for about 10 minutes before serving.
Notes
This casserole is easy to make ahead; just store the creamy base in the dish and add the cornflake topping before baking. It pairs well with roasted chicken or a green salad.
