Can You Freeze Sweet Potato Casserole?

You can make and freeze up to 3 months in advance.

The eggs will be raw when you freeze the casserole, but don't worry - they'll cook perfectly when baked with the sweet potatoes.

How To Freeze It - Unbaked

Prep the Dish: Line your baking dish with heavy-duty aluminum foil, letting the foil hang over the edges.
Prepare the Casserole: Make the casserole as the recipe says, but don't bake it yet.
Freeze: Fold the overhanging foil over the casserole, then put the dish in the freezer. Freeze for 24 to 48 hours until solid.
Remove and Wrap: Take the frozen casserole out using the foil as handles. Wrap it again with another layer of foil.
Label: Use a permanent marker to write the casserole name, topping ingredients and amount, and baking time on the foil. This helps you know what to do when you're ready to bake it.

Freeze for up to 3 months ahead. Thaw the casserole overnight in the fridge before adding toppings and baking.

Important: What About Toppings?

Freezing Casserole with Marshmallow Topping:

If your casserole has a marshmallow topping, freeze the entire (unbaked) casserole without the marshmallows.

Add Fresh Marshmallows Later: Just follow the recipe as instructed and bake with marshmallows.

Freezing Casserole with Crumbly Topping:

Separate Topping: Make the crumbly topping ahead of time. Place the uncooked topping in a zip-top bag or airtight container. You can freeze them the same amount of time like the entire unbaked casserole.
Store Separately: Store the topping in the freezer. When you're ready to bake the casserole, sprinkle the topping on before baking and follow the recipe instructions.

If you can, make the topping fresh on the day.

How To Freeze Leftover Baked Sweet Potato Casserole?

If you have leftover sweet potato casserole, you can keep it in the fridge for 4 to 5 days or freeze it for up to 4 months.

Keep in mind that toppings might become soggy once mixed with the casserole. Wrap the leftovers in foil and label them with the date, so you know when to use them for the best taste.

You can freeze it in the casserole dish or as individual portions in airtight containers.

Can You Refreeze Sweet Potato Casserole?

I would not suggest you refreeze a sweet potato casserole. Once it's thawed you should finish eating it with 2-3 days.

How To Thaw Frozen Sweet Potato Casserole

Take the sweet potato casserole out of the freezer and put it in the fridge at least 24 hours before you plan to bake it, keeping it wrapped. Thawing in the fridge is crucial due to the raw eggs in the casserole. Avoid thawing it on the kitchen counter.

If the casserole is in a baking pan, place a dish towel underneath to soak up any moisture. If it's wrapped in plastic wrap or aluminum foil, place it on a baking tray in the fridge to catch any moisture as it thaws.

How To Reheat Frozen Sweet Potato Casserole?

Remove the casserole from the fridge 2 hours before baking so it comes to room temperature. Placing a cold dish directly into the oven can cause it to crack due to the sudden temperature change.

Once it's at room temperature, follow your recipe's instructions for baking and adding toppings. Use an instant-read thermometer to check that the internal temperature reaches 165°F.

Tips

Seal the sweet potato casserole really well. You want to make sure no air gets in. If it does, the sweet potato casserole will get freezer burn and it won't taste good.
Write the date on the container or aluminum foil before you put in the freezer so you know how long before you should eat it.

FAQs

Does sweet potato casserole go bad?

Like all food, if left uneaten for a significant amount of time, it will go off.

How do you know if your sweet potato casserole is bad?

There are a few ways to determine if your sweet potato casserole is not fit for eating:

Does it smell okay? Take a sniff to see what it smells like.
Do you see any mold? Look for green or black spots on the casserole.
What is the texture? If it casserole is mushy or feels a bit slimy it may have gone bad.

Does it matter if I used canned instead of fresh sweet potatoes when it comes to freezing?

Though both freeze well the canned sweet potato will have more moisture than the fresh sweet potato.

Make sure to blot any excess moisture when you take the sweet potato out of the can so if you do freeze the casserole there isn't too much moisture. This will reduce the risk of a soggy or mushy casserole.

Can you freeze an unbaked sweet potato casserole?

YES, if your want to freeze the casserole unbaked make sure not to add the toppings. It is best to add the toppings just before you bake the casserole for the best taste and texture.
