Freezing Sauerkraut FAQ
Can You Freeze Sauerkraut and Pork?
Although raw or freshly made sauerkraut is best suited for freezing, there is no need to throw out cooked sauerkraut with pork because it is safe to freeze this dish. But since this side dish is cooked, you should freeze it as soon as it has cooled down. To freeze pork and sauerkraut, just spoon the dish into a resealable freezer bag or airtight container. If you’re using a bag, squeeze out as much air as you can before sealing. Write the storage date then stick flat in the freezer. If you want to make thawing easier, we highly suggest dividing a large batch of cooked sauerkraut into single serving portions. Also, try to strain some of the liquids to preserve the crunch of the vegetables. When it comes to reheating, baking in the oven or using a non-stick frying pan would be the best options.
Can You Freeze Sauerkraut and Kielbasa (Sausage)?
Similarly to sauerkraut and pork, there’s no reason not to freezer sauerkraut and sausage. Once the dish has cooled, divide the leftovers into as many portions as you need and transfer them into freezer bags. Label the bags with name and date if needed, then put them into the freezer. Reheat on a non-stick frying pan. Before reheating I’d suggest thawing it on the countertop for an hour or so. This way it’s partly defrosted and it’s much easier not to burn this dish on the frying pan.
Does Freezing Sauerkraut Kill Good Bacteria (Probiotics)?
Fermented foods like sauerkraut are teeming with beneficial bacteria called probiotics. These microbes aid in digestion and promote better health. A 4 to 6 ounce serving of sauerkraut contains trillions of probiotics. But if you made a large batch of sauerkraut, does freezing affect the live culture in the side dish?
There is conflicting information about this issue. Although probiotics are temperature sensitive and the possibility that these beneficial bacteria could die once frozen is high, they won’t be wiped out completely once the sauerkraut is frozen and thawed. Freezing the sauerkraut will only enhance the killing of the probiotics but some of them could survive the cold temps by lying dormant. It is worth noting, however, that the lactic acid in sauerkraut could kill probiotics in storage.
