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 casseroles that are still fresh and of good quality. Old sweet potato casserole will not freeze well and the quality will not improve on freezing.

Make Ahead Sweet Potato Casserole

Since holiday dinners can get a little crazy, you can make sweet potato casserole beforehand and freeze it to save time and stress. We suggest making the sweet potato filling to save prep time, and adding the topping ingredients on the day you are having your holiday meal.

This super easy sweet potato casserole recipe only requires five ingredients.

Fill a large bowl with water and wash six large sweet potatoes to remove any dirt. Using a clean cutting board, peel and slice (or chop) the sweet potatoes.

Place the peeled sweet potatoes in a large pot and boil for around 25 minutes or until fork tender. Drain them and place them in a large mixing bowl together with ½ a cup brown sugar, two tablespoons butter, and one teaspoon cinnamon or pumpkin spice—whichever you prefer.

Using a potato masher, mash the sweet potatoes while still hot, folding in the other ingredients as you go.

If you prefer keeping it chunky, just ensure that the butter, sugar, and spice is well mixed throughout. The ingredients should melt together with the hot sweet potatoes. Now that the casserole filling is ready for baking, your prep for this Thanksgiving side dish is done.

You can either freeze it in the casserole dish you are going to bake it in or in freezer bags using the freezing instructions below.

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 baking 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 baking 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 plastic wrap. Make sure that all the corners and edges are completely sealed and that there are no gaps where air can enter.

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

For leftovers, scoop the casserole into a freezer-friendly airtight container. Alternatively, you can scoop it into a freezer bag. Press out any excess air before sealing the bag.

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

When it’s almost time to bake your dish, let the sweet potato mixture thaw overnight or for a few hours in the fridge.

If you froze the sweet potato mixture in freezer bags, butter an oven-proof dish and transfer the thawed mixture into the dish in an even layer. Add two cups of mini marshmallows on top and bake for 20 minutes to 25 minutes at 375°F until you have a golden topping. Add chopped pecans if you prefer a crunchy topping.

Leftover sweet potato casserole can go straight from the freezer into the oven with no need to thaw. Simply warm it through. Alternatively, place the casserole overnight in the refrigerator to defrost safely and simply warm it through it in the microwave.
