Make Ahead Instructions: If making this dish ahead of time cook the sweet potatoes and combine with the rest of the ingredients. Then smooth into baking dish and cover in the fridge. You can also make the pecan topping ahead of time. Just store everything together and store in a small airtight container in the fridge. Remove from fridge, add pecan topping and bake for 20 minutes. My grandma makes this dish the night before every year and it comes out perfect.Leftover Storage: Store leftovers in the fridge covered for up to 4 days.
