How to Store or Freeze This Dish
Allow the scalloped potatoes to cool completely at room temperature before storing. This prevents condensation, which can make the dish soggy.
Transfer the cooled scalloped potatoes to an airtight container. If you don't have a container large enough, you can use a baking dish covered tightly with plastic wrap or aluminum foil.
Store the container in the refrigerator. The scalloped potatoes will keep well for up to 3-5 days.
For freezing, portion the scalloped potatoes into individual servings. This makes it easier to reheat only what you need.
Wrap each portion tightly in plastic wrap, then place them in a freezer-safe bag or container. Label with the date to keep track of storage time.
Freeze the portions for up to 2-3 months. Beyond this, the texture and flavor may start to degrade.
To reheat refrigerated scalloped potatoes, preheat your oven to 350°F (175°C). Place the potatoes in an oven-safe dish, cover with foil, and bake for about 20-25 minutes or until heated through.
For reheating frozen scalloped potatoes, thaw them in the refrigerator overnight. Once thawed, follow the same reheating instructions as for refrigerated potatoes.
If you're in a hurry, you can reheat the scalloped potatoes in the microwave. Place a portion on a microwave-safe plate, cover with a microwave-safe lid or another plate, and heat on medium power for 3-5 minutes, checking and stirring halfway through.
To maintain the creamy texture, you might want to add a splash of milk or a small pat of butter before reheating. This helps to rehydrate the sauce and keep the dish moist.

- Heat on medium power for 2-3 minutes. Stir halfway through to ensure even heating.
- Continue heating in 1-minute intervals until the potatoes are hot.
Stovetop Method:
- Place the leftover scalloped potatoes in a non-stick skillet.
- Add a splash of milk or cream to help rehydrate the potatoes and prevent sticking.
- Cover the skillet with a lid and heat over medium-low heat.

Air Fryer Method:
- Preheat your air fryer to 350°F (175°C).
- Place the scalloped potatoes in an air fryer-safe dish.
