Instructions

Preheat the oven to 350°F. Grease a 9x13 casserole dish, set aside.
In a large sauté pan over medium-high heat, melt butter. Add onion and cook until translucent, about 5 to 7 minutes. Add garlic and cook for 30 seconds. Remove from the heat and set aside.
In a large bowl, combine all remaining ingredients: sour cream, cream of chicken soup, 1/2 cup melted butter, black pepper, shredded hash brown potatoes and shredded cheddar cheese; stir until well blended. Fold in the cooked onion mixture and pour into prepared baking dish.
In a medium sized bowl, combine the cornflakes and melted butter. Sprinkle evenly over the top of the casserole.
Bake for 40 to 45 minutes, or until bubbly and the top is browned. Serve hot!

Notes

Store: Let the casserole cool completely, then transfer it to an airtight container and refrigerate for up to 5 days.

Reheat: Simply microwave individual portions or cover and warm the whole dish in the oven at 350°F until heated through.

Freeze: Wrap the unbaked casserole tightly in plastic wrap and foil, then freeze for up to 2 months. When ready to enjoy, thaw overnight in the fridge and bake as directed.

Make Ahead: If you’d like to make this casserole ahead of time, you can assemble it a day before, but do not add the cornflake topping. Instead, cover it tightly with plastic wrap or foil and refrigerate for up to 48 hours. When ready to cook, set casserole at room temperature for 30 minutes. Top with the butter and cornflake topping and bake as directed.
