How to Store or Freeze This Dessert
Allow the apple oatmeal crisp to cool completely at room temperature before storing. This helps prevent condensation, which can make the topping soggy.
Transfer the cooled dessert into an airtight container. If you prefer, you can also cover the baking dish tightly with plastic wrap or aluminum foil.
Store the apple oatmeal crisp in the refrigerator for up to 5 days. The cool environment will help maintain the freshness and texture of the apples and the crisp topping.
For longer storage, consider freezing the apple oatmeal crisp. First, ensure it is completely cooled. Then, wrap the entire baking dish tightly with plastic wrap, followed by a layer of aluminum foil. Alternatively, you can transfer the crisp to a freezer-safe container.
Label the container with the date to keep track of its freshness. The apple oatmeal crisp can be frozen for up to 3 months.
When ready to enjoy, thaw the crisp in the refrigerator overnight. This gradual thawing process helps maintain the texture and flavor.
Reheat the apple oatmeal crisp in a preheated oven at 350°F (175°C) for about 15-20 minutes or until warmed through. This will help restore the crispiness of the topping.
If you're in a hurry, you can also reheat individual portions in the microwave. Place a serving on a microwave-safe plate and heat on medium power for 1-2 minutes, checking frequently to avoid overheating.
