What can I freeze?

You might be surprised how much you can freeze. Going away for the weekend? Milk, bread and grated cheese are commonly wasted staples that freeze well. You can also freeze raw or cooked chicken, fish and other meats. Fruit, chillies and ginger, as well as some vegetables that don’t have a high water-content freeze well (see below). Freezing your leftovers is a great way to save food (and time on busy weeknights), just don’t forget to portion and label it so you don’t play freezer roulette later on.

You can’t freeze vegetables that have a high water content, such as lettuce or cucumbers. Avoid freezing whole eggs, but separated egg yolks and whites do freeze (see our guide here). Yoghurt, single cream and low-fat cream cheeses don’t freeze well either.

Here are 8 more food waste freezer hacks to rescue your leftovers:

1. Freeze chillies and ginger whole

Fresh herbs don’t freeze well just as they are. Chop wilting herbs into a pack of butter, along with garlic, chillies and lemon zest if you like, then freeze it in slices to add direct to risottos, pasta, soups and stews. You could also add chopped herbs to ice cube trays and top up with olive oil to add direct to your cooking. 

6. Stock up!

A word of warning: while it’s completely safe to freeze food, do be careful when reheating frozen meat, fish and any cooked leftovers. Defrost them fully before reheating or cooking, and make sure they’re piping hot all the way through. It is safe to eat fruit and vegetables straight from frozen.

Cutting your food waste at home is a great place to start, but what about the waste that happens before it even gets to your shopping basket. Read more here on how Farmdrop helps you cut food waste from farm to fork.
