How to store and freeze food: fridge zones, storage times and safe thawing
What goes on which fridge shelf, which foods shouldn't be chilled, how long cooked dishes keep, how to freeze berries, herbs and meat without losing flavour, and how to thaw safely — no counter-top or hot water.
The right temperature
The fridge should hold 1–4 °C (34–40 °F) and the freezer −18 °C (0 °F) or lower. At +5 °C and above bacteria multiply noticeably faster, and food spoils early. If your fridge has no display, put a cheap thermometer on the middle shelf — the easiest way to check.
Don't cram the fridge full: cold air needs to circulate. And don't put hot food inside — cool the pot to room temperature (but for no longer than 2 hours) and only then put it away.
What goes on which shelf
A fridge has different zones, each with its own job:
- Top shelves — cooked dishes, leftovers, cheese, deli meats: things eaten without cooking.
- Middle shelves — dairy and eggs (in their carton, not in the door).
- Bottom shelf, towards the back — the coldest spot: raw meat, poultry and fish. Always on a plate or in a container so juices don't drip onto other food.
- Crisper drawers — vegetables and fruit that like higher humidity.
- Door — the warmest zone: sauces, drinks, butter. Not milk and not eggs.
What shouldn't go in the fridge
Cold harms some foods rather than protecting them.
- Tomatoes — lose flavour and turn mealy. Keep at room temperature.
- Bananas — go black. Avocados only ripen in the warm; refrigerate them once ripe.
- Potatoes — starch turns to sugar and they taste sweet. They need a dark, cool cupboard.
- Onions and garlic — go damp and sprout. Keep them dry, but away from potatoes: onions make potatoes sprout faster.
- Bread — goes stale faster in the fridge than on the counter. If you can't finish it, freeze it.
- Basil — blackens in the cold. Keep it like a bouquet in a glass of water on the counter.
Herbs, cheese and fruit
Stand parsley, dill and coriander like a bouquet in a jar of water, cover with a bag and refrigerate — they'll last 1–2 weeks. Or wrap the dry herbs in paper towel and keep them in a container.
Cheese 'suffocates' in cling film and goes mouldy. Wrap it in baking parchment or paper, then loosely in a bag.
Apples give off ethylene — a gas that speeds up ripening and spoilage of other fruit and vegetables. Store them separately.
How long cooked food keeps
Refrigerate leftovers within 2 hours of cooking, in closed containers. Split large amounts (a pot of soup) into shallow containers — they'll cool faster.
- Most cooked dishes, soups and sides — 3–4 days.
- Cooked rice — no more than a day.
- Salads with mayonnaise — 12–24 hours.
- Mince and raw fish — 1–2 days; raw meat in pieces and poultry — 2–3 days.
- When in doubt, don't taste it. Throwing it away is cheaper than food poisoning.
How to freeze properly
The enemies of freezing are air and slow freezing. Air causes freezer burn — dry grey patches and off flavours. So pack food flat in zip-lock bags, pressing out all the air. A flat bag freezes and thaws faster and takes less space.
Always label the bag: what's inside and the date. In three months you won't tell beef mince from pork.
- Berries: spread in a single layer on a tray, freeze for 2 hours, then tip into a bag. They won't freeze into one lump.
- Herbs: chop finely, pack into ice-cube trays, cover with olive oil or water and freeze. Ready-made cubes for soups and sauces.
- Bread: slice before freezing — take out one slice at a time, straight into the toaster.
- Vegetables (broccoli, green beans, carrots): blanch 1–3 minutes in boiling water, plunge into ice water, dry and freeze — they keep their colour and texture.
- Soups and sauces: cool and portion, leaving 2–3 cm at the top — liquid expands as it freezes.
How to thaw safely
Never thaw meat or fish on the counter at room temperature: the surface quickly warms into the danger zone while the middle is still frozen. Hot water is a bad idea for the same reason.
- In the fridge — the safest method. A 500 g piece of meat thaws roughly overnight, a whole chicken in about a day. Put it on a plate on the bottom shelf.
- In cold water — faster: submerge a sealed bag in cold water and change the water every 30 minutes. 500 g thaws in 1–1.5 hours. Cook straight away.
- In the microwave on defrost — fast, but the edges can start cooking. Cook immediately after thawing.
Common mistakes
What shortens food's life:
- The fridge is set to +6…+8 °C.
- Raw meat sits on the top shelf and drips onto ready-to-eat food.
- Milk and eggs are kept in the door.
- Tomatoes and bread are kept in the fridge.
- Food is frozen in unlabelled bags full of air.
- Meat is thawed on the counter or in hot water.
- A hot pot goes straight into the fridge — or is left on the stove overnight.
Questions and answers
How long do cooked dishes keep in the fridge?＋
Most keep 3–4 days. Cooked rice no more than a day, mayonnaise-based salads 12–24 hours.
What's the right way to thaw meat?＋
Best in the fridge: 500 g takes roughly overnight. Faster: in a sealed bag in cold water, changing the water every 30 minutes. Not on the counter and not in hot water.
Can I refreeze meat?＋
If it was thawed in the fridge, yes, with a slight loss of flavour. If thawed in water or the microwave, cook it first and freeze the cooked dish.
Why shouldn't tomatoes go in the fridge?＋
Cold breaks down the compounds responsible for flavour and aroma, and the flesh turns mealy. Keep tomatoes at room temperature.
