Do You Have to Refrigerate Rhubarb Crisp?

Yes, you should refrigerate rhubarb crisp after it has cooled.

Here’s why:

● Short-term (same day): If you’re serving it within a few hours, it’s fine to leave it covered on the counter.

● Longer storage (1–4 days): Store it in the refrigerator, tightly covered with foil or plastic wrap. This helps prevent spoilage and keeps the topping from becoming too soggy.

● Reheating tip: For best texture, reheat in the oven or toaster oven to re-crisp the topping.
