Our freezer door was left open and some mince felt a bit squidgey so i thawed it like i should and cooked a huge shepherds pie which i then froze all cooked - so today i want it for tea - i am currently defrosting it in th microwave but its taking forever - can i cook from frozen or should i defrost throughly and then (i am no domestic goddess!) what temp and how long in a fan oven to reheat??
Please dont laugh at me !
