- Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. To freeze, cool completely and store in a freezer-safe container for up to 2 months. Reheat in the oven or microwave.
- Gravy Tip: If your gravy is too thick, thin it slightly with milk before pouring it over the casserole to ensure even coverage.
