How to Defrost Ground Beef Safely

Ground beef dinners like lasagna, burgers and casseroles are almost always in the dinner rotation. So, stocking up on ground beef when it’s on sale and freezing extra packages is a no-brainer. But, when it comes to defrosting and using that ground beef, things can be a little less clear. To help out, we’ll walk you through how to defrost ground beef, regardless of whether you have a day, an hour or five minutes.
Before we talk about defrosting ground beef, you should know how long ground beef can be kept in the freezer.

How to Defrost Ground Beef in the Fridge
If you have 24 hours, defrosting ground beef in the fridge is the way to go. The fridge is the best method for thawing ground beef because it works slowly to evenly defrost the meat. Plus, the fridge will keep your ground beef under 4°C, above which is the “danger zone” for bacteria growth.
To defrost ground beef in the fridge, place your beef in a bowl or zip-top bag and place it on the bottom shelf of your fridge. The bag or bowl will catch any condensation from leaking all over your fridge. After 24 hours, 450g of ground beef should be fully thawed and ready to cook. If you’re defrosting a larger or thicker package of ground beef, it might take a little longer than a day. The best way to defrost steak has a similar method and time frame, by the way.

How to Defrost Ground Beef in Water
Defrosting ground beef in water takes a fraction of the time it takes in the fridge, usually only about an hour. For this method, place your package of ground beef in a zip-top bag, push out as much air as you can and securely close the top. Then, place the bag of ground beef in a large bowl, covering it with cold water. You might want to place something heavy, like a bowl or plate, on top of the bag of beef to keep it under the water. Let the beef defrost for about an hour, being sure to change the water out when it warms, around the 30-minute mark.
Like with the fridge method, defrosting ground beef in water could take a little longer than an hour, depending on the weight and thickness of the package. Don’t try to rush the process by using warm or hot water; It will encourage bacteria growth and even start cooking parts of the ground beef.

How to Defrost Ground Beef in the Microwave
While professional chefs avoid defrosting in the microwave, you can safely defrost ground beef in the microwave in just a few minutes. To do so, transfer the ground beef to a microwave-safe container and pop it in the microwave. Set your microwave to the defrost setting (or, change it to 40-50% power) and microwave the beef for 30 seconds. Flip the ground beef and continue to microwave in 20-30 second increments, flipping after each, until the beef is defrosted.
Since the microwave’s a much hotter method, your ground beef might start cooking a bit on the outside while the inside isn’t fully defrosted. This is perfectly safe, as long as you fully cook the ground beef immediately after it’s microwaved. If you prefer to not have any of your beef cooked in the microwave, you can always transfer and cook the meat in a skillet when it’s still a little frozen in the middle.

Common Questions for Defrosting Ground Beef

Are there ways I shouldn’t defrost ground beef?
Yes, there are methods you definitely shouldn’t use to defrost ground beef. The main method to skip is leaving frozen ground beef out on the counter. The reason goes back to that danger zone of 4°C -60°C.
Leaving ground beef, or any meat, out at room temperature can make bacteria that cause foodborne illnesses to grow and get you very sick.

How long does defrosted ground beef last?
If you defrosted your ground beef in the fridge, it can be stored there, raw, for up to two days.
However, ground beef that has been defrosted in water or the microwave should be cooked right away to prevent bacteria growth.

Can I refreeze defrosted ground beef?
No, we wouldn’t recommend it. While you can technically refreeze ground beef that’s been defrosted in the fridge , it will affect the meat’s flavor and texture. Ground beef that’s been defrosted in water or the microwave should never be refrozen as it has gotten too close or entered the bacteria danger zone.
If you need to refreeze some or all of the ground beef you’ve defrosted, we recommend fully cooking the beef, allowing it to cool and then freezing it.
