How to Store or Freeze Your Rhubarb Crisp
- Allow the rhubarb crisp to cool completely at room temperature before storing. This helps prevent condensation, which can make the topping soggy.
- Once cooled, cover the baking dish tightly with plastic wrap or aluminum foil. Alternatively, transfer the crisp to an airtight container.
- Store the covered rhubarb crisp in the refrigerator for up to 5 days. The cool environment will help maintain its freshness and texture.
- For longer storage, consider freezing the rhubarb crisp. First, ensure it is completely cooled. Then, wrap the baking dish in a layer of plastic wrap followed by a layer of aluminum foil. This double wrapping helps prevent freezer burn.
- If you prefer, you can also portion the rhubarb crisp into individual servings and place them in airtight containers or freezer bags. This makes it easier to thaw and reheat single servings.
- Label the containers or bags with the date to keep track of how long the rhubarb crisp has been stored. It can be frozen for up to 3 months.
- When ready to enjoy, thaw the rhubarb crisp in the refrigerator overnight. For a quicker option, you can also use the microwave on a defrost setting.
- To reheat, preheat your oven to 350°F (175°C). Place the rhubarb crisp in an oven-safe dish and cover with aluminum foil. Heat for about 15-20 minutes or until warmed through. Remove the foil for the last few minutes to help crisp up the topping.
- For a microwave option, place a portion of the rhubarb crisp on a microwave-safe plate and heat on medium power for 1-2 minutes, checking frequently to avoid overheating.
