Ingredients For Cheesy Potato Casserole Recipe
Potatoes: These are the base of the casserole, providing a hearty and filling component.
Cheddar cheese: Adds a rich, cheesy flavor that melts beautifully into the dish.
Sour cream: Contributes to the creamy texture and tangy taste of the casserole.
Cream of chicken soup: Enhances the creaminess and adds a savory depth of flavor.
Crushed cornflakes: Provides a crunchy topping that contrasts nicely with the creamy filling.
Melted butter: Helps to bind the cornflakes together and adds a rich, buttery flavor to the topping.

For an extra layer of flavor, consider sautéing the potatoes in a bit of olive oil and garlic before mixing them with the cheddar cheese, sour cream, and cream of chicken soup. This will give the potatoes a slight caramelization and enhance the overall taste of the casserole.

How to Store or Freeze This Dish
- Allow the cheesy potato casserole to cool completely after baking. This helps prevent condensation, which can make the dish soggy.
- Transfer the cooled casserole to an airtight container. If you prefer, you can also cover the baking dish tightly with aluminum foil or plastic wrap.
- Store the casserole in the refrigerator for up to 3-4 days. When ready to enjoy, reheat in the oven at 350°F (175°C) until warmed through, about 20-25 minutes.
- For freezing, wrap the cooled casserole tightly in plastic wrap, then again in aluminum foil to prevent freezer burn. Alternatively, use a freezer-safe airtight container.
- Label the container with the date and contents to keep track of freshness.
- Freeze the casserole for up to 2-3 months. When ready to eat, thaw overnight in the refrigerator.
- Reheat the thawed casserole in the oven at 350°F (175°C) for 30-35 minutes, or until heated through and bubbly.
- If reheating from frozen, cover the casserole with foil and bake at 350°F (175°C) for 45-50 minutes. Remove the foil for the last 10-15 minutes to allow the cornflake topping to crisp up.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover cheesy potato casserole in an oven-safe dish, cover it with aluminum foil to prevent it from drying out, and bake for about 20-25 minutes, or until heated through.
For a quicker option, use the microwave. Transfer a portion of the casserole to a microwave-safe dish, cover it with a microwave-safe lid or plastic wrap (leaving a small vent), and heat on medium power for 2-3 minutes. Stir halfway through to ensure even heating.
If you prefer a crispy top, reheat the casserole on the stovetop. Place a non-stick skillet over medium heat, add a small amount of butter or olive oil, and spread the casserole evenly in the pan. Cover and cook for 5-7 minutes, stirring occasionally, until heated through and the top is slightly crispy.
For an air fryer method, preheat your air fryer to 350°F (175°C). Place the casserole in an air fryer-safe dish or directly in the basket, and heat for 10-15 minutes, shaking the basket halfway through to ensure even heating. This method will give you a nice, crispy topping.
If you have a toaster oven, preheat it to 350°F (175°C). Place the casserole in an oven-safe dish, cover with foil, and heat for 15-20 minutes, or until warmed through. Remove the foil for the last 5 minutes to crisp up the top.
