How long is it good for:

Serve: As with most recipes with dairy products in them, you shouldn’t leave this Sweet Potato Casserole out for longer than 2 hours.

Freeze: If you’re going to freeze the casserole, we suggest freezing it before it’s baked and without the marshmallows. 

How to get the kids involved with this recipe:

Ages 2-3: Let them sprinkle the marshmallows and pecans on top of the sweet potato mixture. They will love doing this!

Ages 4-5: Have your little one mash the sweet potatoes. They will have fun using their muscles to do this!
