What Are the Benefits of Flash Freezing

Before we walk you through how to flash freeze food—what are the benefits of flash freezing vs regular freezing?

Flash freezing comes from the restaurant and commercial food industries where blast chillers are used to quickly drop the temperature of food. 

Better Texture and Nutrient Preservation

When you freeze food, the moisture content expands and forms crystals. These crystals tend to rupture the cell walls in fruits and vegetables, which is why frozen foods are usually soft or mushy when you defrost them. 

Flash freezing usually produces much smaller, fine ice crystals. This equals less mushiness and better food integrity. Because flash freezing causes less cell rupturing, it can also help to maintain the nutrients in certain frozen foodstuffs. 

Less Waste, More Convenience

Once you know how to flash freeze food, you can wave goodbye to spoiled fresh produce. Anytime you have excess food that’s suitable for flash freezing, you can save it for future use. 

Having flash frozen food on hand can also be super convenient. Did you know that Americans spend almost 400 hours in the kitchen per year? Flash freezing is a great way to food prep ahead of time and streamline meals. 

If you follow the right steps, you also won’t have to struggle with big lumps of food that are frozen solid.

How to Flash Freeze Like a Pro

Starting by cleaning and preparing the food you want to flash freeze. Slice up things like carrots and quarter large fruit like peaches. 

Cover a cookie sheet (or other flat tray) with baking paper. Arrange the individual pieces of food, taking care that the sides don’t touch or overlap. 

Slide your trays into the freezer and leave them for a couple of hours. 

Once your food items are mostly frozen, remove the trays. Portion out the contents into freezer bags or containers. 

For things like burgers and steaks, you can separate the individual pieces with baking paper to further prevent them from sticking together. 

Squeeze out as much excess air as possible, or, even better—vacuum seal your bags. Label your containers and bags, making sure to include the date. You can also list the number of portions.  

Pack back into your freezer, sit back, and enjoy the feeling of accomplishment.

How Long Will My Flash Frozen Food Last

Berries and certain fruits can keep for up to a year in the freezer.
