You can potentially store your sweet potato casserole for longer than this but for the best flavor and results, 4 months is the maximum recommendation.

We invite you to take a look at the following question and answer section. It contains some common question information that may prove to be useful for you as well. 

Do You Reheat Sweet Potato Casserole with Foil?

We do recommend that you leave your sweet potato casserole covered with foil during the majority of your reheating process. This will help keep your toppings from darkening too much or burning during the reheating process. 

How Long Can Sweet Potato Casserole Be at Room Temperature?

With nearly any dish that needs to be stored in the fridge or refrigerator, the rule of thumb is to not leave the dish at room temperature for more than 2 hours. This is because bacteria tend to grow most rapidly when dishes are between 40 and 140 degrees. 

2 hours is the safest protective time frame. If your sweet potato casserole is left out longer than 2 hours, you should consider discarding it for safety purposes. 

Are Sweet Potato Casserole and Candied Yams the Same Thing?

Sweet potatoes and yams are essentially the same things, right? Yams come from the same family as sweet potatoes but really they are quite different when you buy them fresh. While they are often associated as being the same thing, they are not truly the same. 

Do Marshmallows Get Soggy When Reheated?

Because the marshmallows were previously cooked and browned, you shouldn’t have to worry about anything becoming soggy or distasteful during your reheating process.

You can keep your pan covered in foil to prevent excessive cooking but sogginess should not be an issue.
