Forgot to take the chicken out of the freezer? It happens to everyone. So how do you thaw meat fast, without risking food poisoning? The safest method is always the fridge, but there are two quicker options when you need them: cold water in a sealed bag, and the microwave. Here's a butcher's guide to defrosting meat safely, with typical thawing times and what UK food safety guidance says.
Why defrosting matters
Freezing doesn't kill bacteria; it pauses them. As meat thaws, any bacteria present can start to grow again. The Food Standards Agency (FSA) describes the "danger zone" as 8–63°C, the temperature range where bacteria grow fastest. The aim of safe defrosting is to keep the meat out of that zone, which is why you should never defrost meat on the kitchen worktop.
Method 1: in the fridge (safest)
The FSA advises that the safest way to defrost food is in the fridge, ideally overnight. The meat stays cold the whole time.
- Put the meat in a container or on a plate big enough to catch drips.
- Keep it on the bottom shelf, below any ready-to-eat food.
- Once it's fully defrosted, use it within 24 hours, in line with FSA guidance.
Typical fridge thawing times (these vary with your fridge and how the meat is packed):
| Item | Approx. time in the fridge |
|---|---|
| Steaks, chops, chicken breasts, 400g mince | 12–24 hours (overnight) |
| 1kg pack of chicken pieces or diced meat | About 24 hours |
| 2kg joint | About 24–36 hours |
| 3kg+ joint | 2 days or more |
| Large bulk packs (for example, 5kg) | Portion before freezing, or allow 2+ days |
Rough rule of thumb: allow about 24 hours for every 2–2.5kg.
Method 2: in cold water (faster)
When you need meat defrosted in a few hours, cold water is much quicker than the fridge, because water transfers heat far better than air.
- Make sure the meat is in a sealed, leak-proof bag or container. The FSA's guidance for businesses says raw meat and poultry shouldn't be defrosted under cold water unless it's in a sealed container.
- Submerge it in a bowl or sink of cold water (never warm or hot).
- Change the water every 30 minutes, so it stays cold. This is standard advice from food safety agencies, including the US Department of Agriculture.
- Cook it as soon as it has thawed.
Typical cold water times: about 1 hour for small, flat packs such as steaks or chicken breasts, 2–3 hours for 1kg, and longer for joints.
Method 3: in the microwave (fastest)
Use the microwave's defrost setting, following the manufacturer's instructions, and turn or separate the meat regularly. The FSA advises using the microwave on the defrost setting directly before cooking. Microwaves defrost unevenly, and parts can start to warm or cook, so cook the meat immediately afterwards.
It's best for small items, like mince, steaks and chicken breasts, rather than large joints.
What not to do
- Don't defrost meat on the worktop or at room temperature.
- Don't use hot water. The outside warms into the danger zone.
- Don't leave defrosted meat out. Keep it in the fridge until you cook it.
- Don't let raw meat drip onto other food.
Planning ahead: a simple routine
The easiest way to avoid a last-minute thaw is to make it a habit. When you clear up after dinner, take tomorrow's meat out of the freezer and put it on a plate on the bottom shelf of the fridge. For a Sunday roast, move the joint to the fridge on Friday or Saturday, depending on its size. Keep a note on the freezer door of what's in there, so you can plan the week's meals at a glance.
Can you cook meat from frozen?
Some products are designed to be cooked from frozen, and the pack will tell you. Otherwise, the FSA advises defrosting food thoroughly before cooking. That's especially important for large joints and chicken, which might not cook through evenly from frozen.
Freeze smart, thaw faster
The quickest way to defrost meat is to freeze it well in the first place:
- Portion before freezing. Split bulk packs into meal-sized bags.
- Freeze flat. Thin, flat packs thaw much faster than thick blocks.
- Label and date everything.
Our 5kg Frozen Chicken Breast Fillets (£39.99) and Sirloin Steaks 900g-1.1kg (Frozen) (£22.99) arrive frozen. Separate what you need and thaw it overnight in the fridge. Some of our frozen products are marked on the product page as arriving at least partially defrosted, so check it and get it into the fridge or freezer straight away.
Refreezing
Follow the product's own instructions. As a general rule, FSA guidance is that if you've defrosted raw meat, cooking it before you freeze it again is the safe approach. Cooked food can be frozen, but should only be reheated once. See our meat freezer guide for how long each cut keeps.

Defrosting meat FAQs
How do you thaw meat fast?
Seal it in a leak-proof bag and submerge it in cold water, changing the water every 30 minutes, or use the microwave's defrost setting. Then cook it straight away.
What is the safest way to defrost meat?
In the fridge, ideally overnight, on the bottom shelf in a container that catches drips. The FSA recommends this method.
How long does meat take to defrost in the fridge?
Usually overnight for steaks, chops and mince, and about 24 hours per 2–2.5kg for larger joints.
Can you defrost meat on the worktop?
No. At room temperature, the outside of the meat can warm into the 8–63°C danger zone, where bacteria grow.
How long can defrosted meat stay in the fridge?
FSA guidance is to use food within 24 hours of it being fully defrosted.
