Notes

Ensure all leftover components are fresh and at proper serving temperatures before assembling; this casserole is about reheating and melding flavors. For an enhanced flavor profile, consider adding a dash of poultry seasoning or fresh herbs (like thyme or sage) to the turkey mixture. If your stuffing or turkey feels a bit dry, a tablespoon or two of chicken or turkey broth can be incorporated into their respective layers. For an extra textural contrast, a sprinkle of toasted breadcrumbs mixed with melted butter can be added over the mashed potato layer during the last 10 minutes of baking. Always taste and adjust seasoning, especially salt and pepper, as leftover components can vary in their initial seasoning.
