How to freeze Au Gratin Potatoes
Everyone loves au gratin potatoes. Made with thinly sliced potatoes, butter and cheese sauce, and more cheese on top, it is easy to prepare but very appetizing indeed. It is the perfect side dish for almost anything on the menu from soups to salads, meats, and vegetables. Served while still warm, it simply makes meals heartier and more special, making it the ultimate comfort food.
Given that au gratin potatoes are so yummy, it's such a shame to let them go to waste. Good thing you can always freeze your leftover potato dish so you can enjoy them again later. Here's how:
1. Let your potato dish cool down completely. This step is important so that you don't raise the temperature inside the freezer and cause some of the foods stored there to thaw which could affect their texture and taste.
2. You can use the same baking dish if you plan on serving the whole tray or transfer your cooked cheesy potatoes into airtight and freezer-safe containers. Here's a tip: Freeze them in small batches so you can easily reheat them and avoid wasting food. Remember, it is unsafe to refreeze your reheated potato dish.
3. If you're using your baking dish, cover it tightly with multiple layers of plastic wrap or aluminum foil to seal in its freshness.
4. Label and consume within 2 weeks. Beyond this period, the quality of your potato dish might deteriorate.
Can you freeze cooked potato dishes?
Cooked potato dishes, especially those which are covered in butter and cream, are actually freezer-friendly. Some say that they can even last in the cold for 3 months but most cooks recommend that you consume your creamy potatoes in 2 weeks for best results. After all, why would you prolong serving this hearty dish when it goes well with just about anything you cook?
Can you freeze uncooked au gratin potatoes?
Raw potatoes contain so much water so that when you put uncooked potatoes in the freezer, they can turn mushy and grainy once thawed. To solve this dilemma, you can partially cook your au gratin potatoes; about halfway through, before storing them in the cold.
When you're ready to serve them, just defrost and finish cooking until it's completely warm and tender. Partner with roasted chicken or spicy sausage for a satisfying meal.
How long do potatoes au gratin last in the freezer?

Besides, why will you let this delectable dish stay in the freezer for so long?
