This big-batch pie serves 8, so you can eat half straightaway and cool and freeze the remaining half to enjoy in week 4.
Just remember – if you’re batch cooking, let food cool thoroughly before freezing – break it down into portions so it cools quicker, and get it into the freezer within 2 hours. And make sure everything is well wrapped, and labelled for future reference so you’re not playing freezer roulette! Simply thaw in the fridge before use, and use within 48 hours. If you’ve frozen cooked food, don’t freeze it again after reheating it.
