To Freeze:
Transfer to a foil baking pan and cover tightly with foil. Place in the freezer or fridge until ready to take camping.
When it comes to reheating on the campfire, pop it on the grate for about 20 minutes or until piping hot.
Use-by: You can freeze Shepherd’s Pie for up to 6 months. Allow to thaw in the cooler and it will keep for 2-3 days. Alternatively, freshly baked Shepherd’s Pie will last in the cooler for 3-5 days.
