How to Thaw Meat Safely: Fridge, Cold Water and Microwave

The safest way to thaw meat is in the refrigerator, at 4 °C (40 °F) or below, allowing roughly a full day for every 2 to 2.3 kg. When you are short on time, thaw it sealed in cold water, changing the water every 30 minutes, or use the microwave, but in both cases cook it right away. Never thaw meat on the counter, especially in a hot kitchen.

Why counter thawing is risky

Frozen meat is safe indefinitely while it stays frozen, because freezing stops bacteria from multiplying. As soon as it starts to thaw, any bacteria that were present can become active again. The US Department of Agriculture's Food Safety and Inspection Service (USDA FSIS) calls the range between 4.4 °C and 60 °C (40 °F to 140 °F) the danger zone, where bacteria grow quickly.

On the counter, the outer layer of a roast or a turkey sits in that zone for hours while the center is still frozen. In Quintana Roo and Yucatán, where kitchens are often above 30 °C, that happens even faster. FSIS advises that perishable food should not be left out more than two hours, or more than one hour when the temperature is above 32 °C (90 °F). That is why the three safe methods are the fridge, cold water and the microwave.

Method 1: in the refrigerator (best)

Fridge thawing takes planning, but it is the safest and gives the best texture, because the meat never leaves a safe temperature. Keep your fridge at 4 °C or colder and check it with a thermometer; a colder fridge will thaw more slowly. Put the package on a plate or tray on the lowest shelf so any drips cannot reach other food.

FSIS estimates at least 24 hours for every 5 lb (about 2.3 kg) of a large item like a turkey, and its turkey guidance gives 24 hours per 4 to 5 lb (about 2 to 2.3 kg). Even small items need time: a 1 lb (about 450 g) package of ground meat takes about a full day. Once thawed, ground meat, poultry and seafood keep another 1 to 2 days in the fridge before cooking, and beef, pork or lamb roasts, steaks and chops keep 3 to 5 days.

Refrigerator thawing times

Approximate times at 4 °C or below, based on USDA FSIS guidance converted to metric. Thickness, shape and how cold your fridge runs all change the time, so check that the center is soft before cooking.

Item	Typical size	Thawing time in fridge	Keeps after thawing
Whole turkey	4 to 7 kg	About 1 day per 2 to 2.3 kg (2 to 4 days)	1 to 2 days
Whole chicken	1.5 to 2 kg	About 1 day	1 to 2 days
Beef or pork roast	1.5 to 2.5 kg	About 1 day per 2 to 2.3 kg (1 to 1.5 days)	3 to 5 days
Steaks and chops	200 to 500 g	Overnight to 1 day, depending on thickness	3 to 5 days
Ground meat	450 to 500 g	About 1 day	1 to 2 days
Fish fillets	150 to 500 g	Overnight to 1 day; remove vacuum packaging first	1 to 2 days
Shrimp	500 g to 1 kg	Overnight	1 to 2 days

Method 2: in cold water (faster)

Cold water thaws meat far faster than air because water transfers heat better. The meat must be in a leak-proof package or a sealed zip-top bag, otherwise water can carry bacteria onto it and the meat absorbs water. Submerge it completely in cold tap water and change the water every 30 minutes so it stays cold. Do not use hot water, which warms the surface into the danger zone.

According to FSIS, a package of about 450 g can thaw in an hour or less, a 1.5 to 2 kg package in 2 to 3 hours, and a whole turkey takes about 30 minutes per pound, roughly 1 hour per kg. Cook meat thawed this way immediately.

Steaks or ground meat, 450 to 500 g: up to about 1 hour.
Roasts or whole chicken, 1.5 to 2 kg: about 2 to 3 hours.
Whole turkey: about 1 hour per kg, so a 6 kg bird needs about 6 hours.

Method 3: in the microwave (fastest)

Microwave thawing works for small portions you plan to cook immediately. Remove the meat from plastic wrap and vacuum bags, place it in a microwave-safe dish, use the defrost setting by weight and turn or separate pieces as they soften. Some edges will start to cook while the center is still frozen, which is why the meat must be cooked right after thawing. It is not a good option for large roasts or turkeys.

Can you refreeze thawed meat?

Meat thawed in the refrigerator can be refrozen without cooking, although it may lose some quality because of moisture lost during thawing. Meat thawed in cold water or in the microwave should be cooked before refreezing. Once cooked, it can be frozen again. Any meat left out of the fridge for more than two hours, or one hour in hot weather, should not be refrozen.

You can also skip thawing altogether: FSIS notes that meat and poultry can be cooked from frozen, but it will take about 50 percent longer. This works well for steaks, burgers and fish fillets; it is less practical for a whole turkey.

Vacuum-sealed packages

Vacuum-sealed meat is convenient to thaw. The packaging is already leak-proof, so beef, pork, lamb and chicken can go straight into a cold water bath; check first that the bag has no punctures. In the fridge, leave the package on a plate in case it leaks.

Fish is the exception. Clostridium botulinum, the bacterium behind botulism, can grow without oxygen, and some types can grow at refrigerator temperatures. Food safety specialists at Michigan State University and state agencies such as Wisconsin's Department of Agriculture and Rhode Island's Department of Health therefore advise removing fish from its vacuum packaging, or at least opening it, before thawing. If you need to thaw fish fast, move it to a regular zip-top bag and use the cold water method, then cook it right away.

Organic Rancher products arrive vacuum-sealed and frozen, so the same rules apply: move them to the freezer on arrival and thaw only what you will cook.

Frequently asked questions

How long does it take to thaw a turkey in the fridge?

Plan on about one day for every 2 to 2.3 kg. A 6 kg turkey needs around three days, so take it out of the freezer early.

Can I thaw meat on the counter if I cook it soon?

It is not recommended. The surface can reach unsafe temperatures while the inside is still frozen, especially in a hot kitchen. Use the fridge, cold water or the microwave instead.

Is it safe to refreeze thawed meat?

Yes, if it was thawed in the fridge and has not been left out. Meat thawed in cold water or the microwave should be cooked first, then it can be frozen.

Can I cook meat straight from frozen?

Yes. It is safe, but allow about 50 percent more cooking time and check the internal temperature with a thermometer.

Why should I open vacuum-packed fish before thawing?

Without oxygen, some botulism-causing bacteria can grow even at fridge temperatures. Opening the package removes that low-oxygen environment.
