How To Properly Store And Freeze Your Brisket

How you wrap and store your brisket is crucial since it will have a direct impact on its quality and flavor. 

Oxygen and dehydration are two things you want to avoid as much as possible. These are your meat’s biggest enemies, and the best way to defend your brisket from them is a food vacuum sealer.

Using a vacuum sealer can help get rid of the oxygen around the brisket. Meanwhile, the thick plastic wrap will be able to prevent evaporation from rearing its ugly head. Besides, it will keep all the moisture in while preventing freezer burn. 

If you don’t have a vacuum sealer, what you can do is to use a cling film to wrap your beef brisket as tightly as possible. Then, hold the plastic wrap in place with an aluminum foil. Next, place your mean in a sealable freezer bag. The aluminum foil will prevent freezer burn while the plastic bag will ensure that odors will not penetrate it.

Most people will freeze their brisket whole. But if you slice them, ensure that they’re in the bag and pour in a few pan drippings, au jus, and leave any jelly stuck on your beef. These will keep all the slices tender and moist once you thaw them later on. Also, you will use the juice when reheating the brisket.

Here are some additional tips to keep in mind:

  • Do not forget to label the bags of your brisket with the date when you place it in the freezer. Also, make sure to include everything that’s in the bag. 
  • Only use heavy-duty aluminum foil when storing your brisket. The last thing you want is to use a cheap one that will easily rip out while you’re storing your meat, exposing it to contamination.
  • If you’ll slice your beef, let the slices cool first and sit in their juice before storing them. Do not put them directly in the freezer so that they won’t dry out once you reheat them.
  • Place your brisket slices on flat sheets of baking paper during their initial freezing. One they’re firm, you can place them in the bags, making sure to follow the steps mentioned above.

How you freeze your leftover brisket will mainly depend on whether you want to slice it before or after freezing it. Here are the pros and cons of each:

Slicing Before Freezing


  • When you slice your brisket before freezing, you’ll bee able to reheat the slices individually. This is very convenient if you only want to reheat a few slices at a time.

  • You may end up with dried out slices if you’re not careful enough.
  • Sliced meats have more surface area, making it more prone to exposure to contamination. So make sure to put your brisket slices in the freezer right away as soon as you’ve prepared them to avoid any problems.

Slicing After Freezing


  • Freezing a whole brisket will help retain more of its moisture.
  • It’ll be less prone to contamination since there’s less surface area exposed.
