How to Store or Freeze This Dish
Allow the au gratin potatoes to cool completely before storing. This helps prevent condensation, which can make the dish soggy.
Transfer the potatoes to an airtight container. If you don't have one large enough, you can use multiple smaller containers or even resealable plastic bags.
Store the container in the refrigerator. The au gratin potatoes will keep well for up to 3-5 days.
For freezing, wrap the baking dish tightly with plastic wrap, followed by a layer of aluminum foil. This double layer helps prevent freezer burn.
Alternatively, you can portion the potatoes into individual servings and place them in freezer-safe containers or bags. This makes reheating easier and quicker.
Label the containers with the date. This ensures you use the au gratin potatoes within 2-3 months for the best quality.
When ready to reheat, thaw the potatoes in the refrigerator overnight. This gradual thawing helps maintain the texture and flavor.
Reheat in the oven at 350°F (175°C) until heated through, usually about 20-25 minutes. If reheating from frozen, it may take up to 45 minutes.
For a quicker option, you can reheat individual portions in the microwave. Place the potatoes in a microwave-safe dish, cover with a microwave-safe lid or plastic wrap, and heat on medium power until warmed through, stirring occasionally.
To restore the crispy top, you can place the reheated au gratin potatoes under the broiler for a few minutes. Keep a close eye to avoid burning.
How to Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Place the leftover au gratin potatoes in an oven-safe dish. Cover with aluminum foil to prevent drying out. Bake for about 20-25 minutes, or until heated through. For a crispy top, remove the foil during the last 5 minutes of reheating.
Microwave Method: Transfer a portion of the potatoes to 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, then check and stir. Continue heating in 1-minute intervals until thoroughly warmed. Be cautious, as the cheese can become very hot.
Stovetop Method: Place the potatoes in a non-stick skillet over medium-low heat. Add a splash of milk or cream to help rehydrate the dish. Cover and heat for about 10-15 minutes, stirring occasionally, until the potatoes are heated through and the cheese is melted.
Air Fryer Method: Preheat your air fryer to 350°F (175°C). Place the au gratin potatoes in a suitable air fryer dish or basket. Heat for 10-15 minutes, shaking or stirring halfway through, until the potatoes are hot and the top is crispy.
Toaster Oven Method: Preheat your toaster oven to 350°F (175°C). Place the potatoes in an oven-safe dish and cover with foil. Heat for 15-20 minutes, removing the foil for the last 5 minutes to crisp up the top.
