Can you refreeze hash browns?

Hash browns are a common and popular staple for many people and cultures around the globe who have each their own unique signature recipes for this all-time favorite. Regardless of what else may be included in individual recipes, hash browns are made primarily of potatoes.

The potatoes are finely grated or diced so that the pieces are quite small and then they are fried in hot oil. Due to the starch present in potatoes, they naturally coalesce and solidify into a patty as they cook in the oil, producing a cake-like portion of culinary goodness.

Hash browns originated in the United States in the late eighteen hundreds as a breakfast item and traditionally this has remained the case as most people still consider the hash brown a breakfast item.

In the southern region of the US which is associated with culinary greatness, the hash brown is crafted into a more delicious relish by incorporating chilies, garlic, cinnamon or cardamoms, bell peppers, and other garnishings.

Fast food giants such as Mcdonalds and Burger King began to produce the beloved delicacy in the 1980s, again as a breakfast item, commercializing the making and sale of hash browns as we know them today.

What happens to hash browns when they thaw?

When frozen food thaws, in this case, hash browns, the crystallized moisture contained in the cells of the food slowly melts and flows throughout the food in the form of droplets of water soaking the ingredients that make up the food. 

The hash browns lose the crunchy quality they have when purchased and when frozen. The soaking wet potatoes will lose their texture and their taste making them less tasty than they were before thawing out.

If you thaw out your hash browns in the refrigerator, the process is much slower and the hash browns may be able to get back that crunchy texture should you heat them up in the microwave or on a pan. They will however not taste the same as the originally fresh item.

If hash browns thaw at room temperature, they will become soggy and that much more difficult to successfully reheat to the desired food quality they came with. 

They are however still safe to consume provided they have not been exposed to air and bacteria for too long such that they begin to go bad and emit a foul smell. If this happens simply discard them. 

The non-acidic nature of potato starch means bacteria can develop very fast once the process of thawing has begun. 

Room temperatures are particularly favorable to dangerous microorganisms that cause food poisoning so make sure thawed hash browns are cooked and eaten as soon as they are thawed. 

But if you change your mind in the process, you may want to return them to the freezer. If you decide to refreeze hash browns this is what you ought to know.

Can you refreeze hash browns?


You can refreeze hash browns after thawing the question is really how much thawing they have already undergone and at what temperatures.

In the refrigerator.

If they had been in the refrigerator which is approximately at 40 degrees Fahrenheit, the hash browns will still be in great condition with most of their moisture remaining within the cells of the food despite no longer being in crystallized form.

While the hash brown may not regain its previous crunch, it will still freeze back to solid form retaining a lot of the flavor and texture. 

This is still, however, dependent on how long the hash browns remained thawed within the refrigerator. Hours are quite alright, a day is within reason and three days should not be exceeded.

Beyond three or four days refreezing should completely alter the nature of the hash brown and when you reheat it eventually it will be a tasteless mess not worthy of the effort.

If you cannot recook the hash brown creatively to create a new potato-based dish then this over-thawed patty should be thrown out. 

Refrigerated hash browns are not automatically safe for consumption in the long run since bacteria only acts slower in the refrigerator part of your fridge but do not altogether deactivate or die.

The much lower temperatures in the freezer are unfavorable for most bacteria to thrive and will either die or become completely inactive leaving your hash browns that much fresher for up to a month or more if the power holds.

Simply put you can safely refreeze hash browns if they have not been thawed for long.

At room temperature.

Hash browns thawed at room temperature likely have moisture leaking from them in the form of water. This means that if you refreeze your hash browns they will have changed in consistency and composition, affecting the taste and texture of the food.

That said, they are still safe for consumption as long as you can ascertain that the smell has not begun to change. 

While there is not a fixed amount of time as to how long they can safely thaw at room temperature before beginning to go bad, in forty-eight hours, even the appearance of the hash browns will have considerably changed due to oxidation of the starch and by seventy-two hours, the characteristic smell of fermenting food will be evident.

To be safe, if your hash browns have been on your kitchen island for about eight hours, it is time to consume them or refreeze them since further exposure will render them either tasteless or dangerous to consume.

Refrozen hash browns in this scenario will not be tasty once you retrieve them from your freezer a second time but they will be safe to consume.


Thawed food loses moisture leaving the food without the succulence it had when fresh or when freshly frozen.

Refreezing solidifies the food back but since the food has acquired a different consistency, refreezing cannot restore the food to its original state. It only stops the food from deteriorating further and losing even more of its succulence and moist goodness.

Hash browns can be safely refrozen but the taste will be notably different.
