If you’re like me defrosting frozen ground beef is a common kitchen scenario. After all buying in bulk and freezing is an easy way to save money and reduce trips to the store. But when it comes time to thaw that brick of frozen beef for tonight’s tacos, what’s the best method? Can you really just toss it in a bowl of cold water and let it defrost quickly that way?
As a home cook and food safety advocate, I’ve done lots of research on the safest thawing techniques While the cold water method often gets suggested for fast thawing, there are some risks to be aware of. In this article, I’ll walk through the safety considerations of using cold water to defrost ground beef. Read on to learn the expert recommendations so you can decide if it’s right for your kitchen
Overview of the Cold Water Thawing Method
First, let’s review the basics of thawing ground beef in cold water. Here’s a quick rundown of the process:
-
Place the frozen ground beef in a leak-proof plastic bag or container. This prevents water from seeping into the meat during thawing.
-
Fill a bowl or sink with the coldest tap water possible. Submerge the bagged beef completely.
-
Change the water every 30 minutes to keep it maximally cold.
-
Allow about an hour per pound of meat for full thawing.
-
Once thawed, immediately cook the ground beef. Don’t allow it to sit at room temperature.
At first glance, this seems like an easy way to quickly defrost ground beef to use in recipes. But given the highly perishable nature of raw meat, it pays to take a closer look at whether this hurried thawing method is worth the risk.
The Dangers of Thawing Meat at Room Temperature
Here’s the first red flag with the cold water technique – despite your best efforts, that water is gradually warming up to room temperature as the meat defrosts. And thawing ground beef completely at room temp can be hugely problematic from a food safety standpoint.
According to USDA guidelines, meat should never be thawed at room temperature. This is because the warm temperature creates an optimal breeding ground for bacteria. Leaving raw meat to linger for several hours in the temperature danger zone between 40°F and 140°F is asking for trouble.
Even if that cold tap water starts out at 40°F or below, it likely only takes about 20-30 minutes before it reaches that risky room temperature zone. This means the majority of the thawing time, your ground beef is at an unsafe temperature.
Higher Risk of Bacterial Contamination
When defrosting ground beef in cold water, it’s extremely difficult to ensure it stays out of the temperature danger zone. And even a little time at unsafe temps can lead to rapid bacterial overgrowth on the raw meat.
Salmonella, E. coli, Listeria, and other nasty pathogens thrive in the 40°F to 140°F range. Just a small starting dose of bacteria on your ground beef can multiply to dangerous levels after several hours of thawing at room temperature.
This significantly raises your risk of severe food poisoning if you were to then cook and consume that meat. Any bacteria present likely wouldn’t get killed off, even with thorough cooking.
Safety Precautions You Should Take
Okay, maybe you aren’t totally convinced to ditch the cold water method yet. I get the convenience factor, and it does shave significant time off the thawing process. If you do choose to thaw ground beef in cold water, here are some important safety steps to take:
-
Check the water temperature frequently with a thermometer. Throw out and replace once it hits 40°F.
-
Don’t leave the meat unattended. Monitor it to minimize time in the danger zone.
-
Disinfect any platters or surfaces the raw meat touches.
-
Cook the beef thoroughly to 160°F immediately after thawing.
-
When in doubt, throw it out. Don’t risk eating questionable meat.
But ultimately, even with these precautions, thawing in cold water still comes with risks due to the fluctuating water temperature. For vulnerable groups like pregnant women, children, and the elderly, it’s better to avoid this method altogether.
The Verdict: Choose a Safer Thawing Method
At the end of the day, while cold water thawing seems appealing for its speed, food safety experts agree it’s wiser to opt for a slower thawing method that keeps ground beef consistently cold. Here are some safer alternatives to consider:
-
Thaw in the refrigerator: Keep meat in original packaging and allow 1 day per 5 lbs.
-
Microwave defrost: Use the defrost setting in 2-minute increments with frequent flipping.
-
Cook from frozen: Skip thawing and just increase cook times as needed.
-
Cold water bath: Only works for small cuts like steaks. Use ice water and fully submerge.
For optimal food safety, plan ahead and thaw ground beef overnight in the fridge. While cold water defrosting might save you some time, it’s just not worth the bacteria risks for vulnerable groups. Use a thermometer and trust your nose to stay vigilant.
The next time your recipe calls for thawed ground beef, resist the urge to take risky shortcuts. Instead, keep harmful foodborne pathogens at bay and protect yourself using smarter, safer thawing methods. Your stomach will thank you!

Q: Please detail the step-by-step instructions for defrosting ground beef using the microwave
A: This is a little trickier depending on your microwave. Most microwaves have a defrost setting or button, so you can use that. The key here is to use low power setting for short bursts until thawed. Most meat needs about 8 minutes per lb but that can differ by microwave or cut of meat. It can also be hard to thaw food in the microwave because it can turn more delicate meats into mush and change the texture of your final meal by “cooking” them.
Q: Please detail the step-by-step instructions for defrosting ground beef using cold water
A: If you can’t wait a day to thaw, you can place wrapped ground beef into cold water. Be careful to use sealed packages instead of paper ones, because packages that leak or dissolve will make the water dirty. It’s not necessary to keep the water running, so putting frozen ground beef in a bowl of cold water works. Change the water about every 30 minutes and most products will be thawed in just a few hours. Never use warm water to thaw meat, as it provides a perfect environment for bacteria to grow. Make sure that the container with the meat and water stays in the sink and not on the counters so that any splashes don’t get on them.

How long can frozen ground beef sit in water?
How do you thaw ground beef?
Run water constantly over the bag of protein until thawed, or place the bag of ground beef in a bowl full of cold tap water and ensure it is completely submerged. If you choose the latter method, it is less hands-on than running water over the package, but “the water must be changed every 30 minutes as the food continues to thaw,” Brigman says.
Can You thaw beef in cold water?
Make sure that the water stays cold. You don’t want to thaw beef in warm water. Although it would thaw faster in warm water, it also makes it more likely to get bacteria on the outer layer of beef. One pound of ground meat will take about one hour to defrost in a bowl of water, then it should be cooked right away.
Can You defrost ground beef in cold water?
To defrost ground beef in cold water, make sure the beef is sealed in a leak-proof package, like a resealable plastic bag. “Set the plastic bag with the frozen meat in a sink or, preferably, in a large bowl, cover with cold water, and weigh the package of meat down with something heavy,” Detwiler says.
Can You refreeze thawed beef?
Although it would thaw faster in warm water, it also makes it more likely to get bacteria on the outer layer of beef. One pound of ground meat will take about one hour to defrost in a bowl of water, then it should be cooked right away. You should not refreeze meat that has been thawed using the cold-water method.
