Can You Freeze Sweet Potato Casserole?

Although it can be eaten any time of the year, sweet potato casserole is undoubtedly a sign that the holidays are around. 

There are a few other times when you can enjoy what tastes like dessert with your main meal since sweet potato casserole is a delicious mix of sweet potatoes topped with marshmallows for a soft, sticky, savory, and sweet vegetable dish all in one.

It would be tragic to see even a spoonful of sweet potato casserole go to waste just because you can’t finish the entire batch before it starts to go bad.

Luckily, sweet potato casserole can be frozen to extend its shelf life and it can also be transformed into new delicious meals. 

Here is everything you need to know when freezing sweet potato casserole.

Types of Sweet Potato Casserole

Popularly enjoyed over Thanksgiving and Christmas holidays, sweet potato casserole is a dish made by cooking sweet potatoes until soft and very tender, layered either sliced or mashed with butter and sugar, and topped with marshmallows before going into the oven to form a toasty caramelized coating.

Variations on the dish include the addition of pecan nuts, vanilla, or taking on a more savory approach and replacing the sweet marshmallows with a breadcrumb topping instead.

Can Sweet Potato Casserole Be Frozen?

Sweet potato casserole always seems to yield a large batch which means loads of leftovers. The great news is that sweet potato casserole can be frozen.

Whether it is a full dish made in advance or leftovers from your meal, sweet potato casserole is pretty easy to freeze and can be used in a variety of ways on defrosting.

Always protect the frozen food from contact with moisture and air as this will quickly lead to quality deterioration.

Only freeze sweet potato casserole which is still fresh and of good quality. Old sweet potato casserole will not freeze well and the quality will not improve on freezing.

How To Freeze Sweet Potato Casserole

If you are making your sweet potato casserole ahead of time with the intention of freezing it, preparing it in a disposable aluminum foil dish is highly recommended.

This way, the dish is suitable at both freezing temperatures and to go straight into the oven without having to worry about it cracking. You also won’t be stuck with a casserole dish occupied in the freezer if needed for other cooking.

Step 1: Cool

Let the casserole cool completely to room temperature. To speed up the cooling process, place the casserole in the refrigerator.

It is not advisable to leave the dish out of the refrigerator for more than 2 hours as there will be a high risk of harmful bacterial growth.

Step 2. Pack and Cover

If you are freezing an entire premade casserole, wrap the casserole dish with a double layer of cling film. Make sure that all the corners and edges are completely sealed and that there are no gaps where air can enter.

Wrap the dish again fully in a layer of foil, again ensuring that there are no exposed gaps.

For leftovers, scoop the casserole into freezer-friendly airtight containers. Cover with a lid ensuring that the container is completely protected from air entering.

Step 3: Label and Freeze

Label the containers with the date and contents and place it in the freezer.

How To Thaw Frozen Sweet Potato Casserole

Sweet potato casserole can go straight from the freezer into the oven with no need to thaw. If you do wish to thaw the casserole, place it in the refrigerator to defrost overnight.
