What temp and time to reheat Shepard's pie?

To reheat shepherd's pie, preheat your oven to 350°F (175°C). Cover the dish with aluminum foil to prevent it from drying out, and heat for about 25-30 minutes, or until it reaches an internal temperature of 165°F (74°C). If using a microwave, heat on medium power for about 5-7 minutes, stirring occasionally, until thoroughly warmed.
