Make Ahead Information
To make this casserole ahead of time, simply prepare the mashed sweet potatoes and streusel as instructed but keep separate – meaning, don’t assemble the casserole.
Allow the sweet potatoes to cool and then place in an airtight container in the fridge. Place the prepared streusel in ziploc bag or airtight container in the fridge as well. These will keep for 2 to 3 days.
Assemble when you are ready to bake and add an additional 5 to 8 minutes to the cooking time.
