Top Tips
- Use real sweet potatoes when possible. Fresh sweet potatoes give the best flavor and texture compared to canned.

- Add topping last if prepping ahead. This keeps marshmallows or streusel from getting soggy.
- Let it rest before serving. A short rest helps it set and makes serving easier.
- Taste before baking. Always sample the filling so you can adjust sweetness and spices.
- Refrigerator: Let the casserole cool completely, then cover tightly or transfer to an airtight container. Store in the fridge for up to 4 days.
- Freezer: For best results, freeze the casserole without the topping. Wrap tightly in plastic wrap and foil, or use a freezer-safe container. Freeze for up to 2 months.
