How to Store / Freeze This Dish
Allow the au gratin potatoes to cool completely before storing. This prevents condensation from forming, which can make the dish soggy.
Transfer the cooled 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 au gratin potatoes will stay fresh for up to 3-4 days.
For longer storage, consider freezing. Wrap the entire baking dish tightly with plastic wrap, followed by a layer of aluminum foil to prevent freezer burn.
Alternatively, you can portion the potatoes into individual servings and place them in freezer-safe containers or resealable plastic bags. This makes reheating easier and more convenient.
Label the containers with the date to keep track of how long they’ve been stored. Au gratin potatoes can be frozen for up to 2 months.
When ready to reheat, thaw the potatoes in the refrigerator overnight. This ensures even reheating and prevents the dish from becoming watery.
Preheat your oven to 350°F (175°C). Transfer the au gratin potatoes to an oven-safe dish if they were stored in a plastic container.
Cover the dish with aluminum foil and bake for 20-25 minutes, or until heated through. For a crispy top, remove the foil during the last 5-10 minutes of reheating.
If you prefer to use a microwave, place the potatoes in a microwave-safe dish and cover loosely. Heat on medium power in 2-3 minute intervals, stirring in between, until hot.
Enjoy your reheated au gratin potatoes as a delicious side dish to complement any meal!
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover au gratin potatoes in an oven-safe dish. Cover with foil to prevent drying out and bake for 20-25 minutes or until heated through.
For a quicker method, use the microwave. Place a portion of the potatoes in a microwave-safe dish. Cover with a microwave-safe lid or plastic wrap, leaving a small vent. Heat on medium power for 2-3 minutes, stirring halfway through to ensure even heating.
If you prefer a crispy top, use the broiler. First, reheat the potatoes in the microwave for 2-3 minutes. Then, transfer them to an oven-safe dish and broil on high for 2-3 minutes until the top is golden and bubbly.
For stovetop reheating, place the potatoes in a non-stick skillet over medium-low heat. Cover with a lid and heat for 10-15 minutes, stirring occasionally to prevent sticking and ensure even heating.
If you have an air fryer, preheat it to 350°F (175°C). Place the potatoes in the air fryer basket in a single layer. Heat for 5-7 minutes, shaking the basket halfway through to ensure even heating and a crispy top.
