Your freezer is the best money-saving tool in the kitchen. Used well, it means less waste, cheaper shopping and a homemade dinner on nights you can’t face cooking. Here’s what works, what doesn’t, and how to do it safely.
Freezes brilliantly
- Soups, stews, curries, chilli and pasta sauces — the ultimate freezer food.
- Bread — slice it first so you can toast straight from frozen.
- Raw and cooked meat and fish, well wrapped.
- Grated cheese, butter and milk (milk may separate a little; shake it well).
- Berries and sliced bananas — perfect for smoothies and baking.
- Herbs chopped into ice-cube trays with a little oil or water.
- Cooked rice, as long as it’s cooled quickly and frozen promptly.
Doesn’t freeze well
- Salad leaves, cucumber and radishes — they turn limp and watery.
- Hard-boiled eggs — the whites go rubbery.
- Cream- or yoghurt-based sauces — they can split. Freeze the base and add the dairy when reheating.
- Fried and crispy food — the crunch doesn’t survive.
- Raw potatoes — they go grainy. Cooked mash and roast potatoes freeze fine.
How to freeze food properly
- Cool it quickly — split big batches into smaller containers — and freeze it within a couple of hours of cooking.
- Portion it so you only defrost what you need.
- Squeeze out the air. Air causes freezer burn — the dry, greyish patches that spoil texture.
- Freeze bags flat, then stand them up like files once they’re solid.
- Label everything with what it is and the date. You won’t remember.
Keep your freezer at -18°C. Food stays safe while it’s frozen, but quality slowly drops, so aim to eat most cooked dishes within about three months.
Defrosting safely
- The safest way is in the fridge, overnight, on a plate to catch drips.
- Once defrosted, cook or eat it within 24 hours.
- Don’t refreeze raw food that has defrosted — but you can cook it and then freeze the cooked dish.
- Reheat until steaming hot all the way through, and only reheat once.
