How to Make Sweet Potato Casserole ahead of time.
You can pre-steam your potatoes and freeze or refrigerate (up to 3 days) them. I do suggest only freezing the steamed potatoes. For the best consistency, add the milk, butter, and cinnamon once the potatoes are defrosted and warmed.
To warm, allow potatoes to thaw. Once thawed, add the to a stock pot with milk, butter and cinnamon and heat. About 5-6 minutes.
Add marshmallows, pecans, and sugar over the top of the potatoes.
Bake for 15 minutes at 350 degrees f.
