Notes
Storage & Leftovers
Store any leftovers in an airtight container in the refrigerator for up to five days. This stores and reheats well.
Freezing
This dish also reheats and freezes well. To freeze the sweet potato casserole with marshmallows, make it up until the point you are going to add the marshmallows. Cover, freeze, and store until you need it. It should keep for 4-6 months.
Make Ahead
You can easily make this ahead of time for a holiday meal. Make the mashed sweet potatoes and put them in a casserole dish. It can stay in the fridge up to 48 hours before your event. Let it warm to room temperature for about 30 minutes before baking. When you are ready to bake the sweet potato casserole with marshmallows, ADD the marshmallow on top and bake according to the instructions.
Vegetarian
Traditional marshmallows are not completely vegetarian. If you are not comfortable eating gelatin, please substitute out vegan marshmallows.
Casserole Dish
I make this casserole in a 1 ½ quart oval casserole dish. I'll often double it, and then it fits in a standard 9x10 dish.Nutrition
