👩🍳Chef’s Tips
- Reheat in Portions: If possible, reheat only the portion you plan to eat rather than the entire casserole. This helps maintain the quality of the leftovers.
- Add Moisture: If the casserole seems dry after reheating, you can add a small amount of milk, cream, or melted butter to restore its creaminess. Mix it in gently.
- Check for Crispy Toppings: If your casserole has a crispy topping (e.g., marshmallows or nuts), and you’re using the oven to reheat, you may want to remove the foil for the last few minutes of reheating to crisp it up.
- Don’t Overdo It: Avoid overheating the casserole, as it can become mushy or dry. Reheat just until it’s hot throughout.
- Plan Ahead: If you know you’ll be reheating leftover sweet potato casserole, store it in individual portions in the fridge or freezer for easier reheating and less waste.
