Freezing locks in vitamins and nutrients.

freezing

Freezing is a quick and convenient way to make your fruits and vegetables last well past harvest. When you freeze food correctly, it pauses the aging process and locks in the nutritional value, preserving the fresh-food goodness for a long time. Freezing also helps reduce food waste. If you bought too much, don't toss it away; instead, take a few minutes to freeze and save for later. Read Extension's Guide to Freezing Food and watch this short video on the supplies you'll need for freezing foods.

Follow these basic steps

  • Freeze food within a few days, making sure that potentially hazardous food, such as raw meat or cooked food, was never left at room temperature for more than 2 hours.  
  • Use proper packaging that is safe for the freezer. Use smaller containers, no more than 4-inches deep, to maintain quality and prevent ice crystals from forming.  
  • Ensure proper airflow by allowing space around the container when placing it in the freezer.  
  • Check your freezer temperature and maintain the freezer temperature at 0° Fahrenheit or less to freeze the food rapidly.  

Follow these steps for freezing produce

  • Wash and drain produce before removing cores, pits, seeds, skins, etc. Wash small amounts at a time through several changes of cold water. Do not let the produce soak.  
  • For fruits, determine how to prevent discoloration, if needed, and select your packing type. Most fruits have a better texture and flavor if packed in sugar or syrup. For more information, see Freezing Food: Fruit.  
  • For vegetables, following appropriate blanching times and cool quickly by plunging into cold ice water, then drain. Blanching is to scald vegetables in boiling water or steam for a short time. Determine if you are doing a dry or tray pack. For more information, see Freezing Food: Vegetables.  
  • Pack in proper containers, leaving sufficient space between the top of the packed food and the closure of the container.  
  • Label the container with the product name and the current date, and freeze at 0°F or below for 8-12 months for best quality.  

Select the proper container

  • Place food in airtight containers made of plastic or glass, such as plastic freezer containers with tight-fitting lids or wide mouth canning jars. Do not use regular glass jars; they break easily at freezer temperatures.  
  • Another option is to use plastic freezer bags and moisture-vapor resistant wrapping materials, such as plastic freezer wrap, freezer paper and heavy-duty aluminum foil, which are suitable for dry-packed foods with little or no liquid. Press to remove as much air as possible before closing.  
  • Before placing in the freezer, label the wrapping or the airtight container with the product name, the current date, and the recommended storage time.  

Thaw foods safely

Thaw using one of the four safe methods:  

  • Thaw in the refrigerator.  
  • Thaw food in a leak-proof plastic bag immersed in cold water, and change the water every 30 minutes.  
  • Thaw in the microwave and cook it immediately after it has been defrosted.  
  • Thaw during the cooking process, such as frozen hamburger patties on the grill.  

Never thaw foods outside or in a garage, basement, or on the kitchen counter. These methods can leave your foods unsafe to eat. Once food is thawed in the refrigerator, it is safe to refreeze it without cooking; however, the quality may suffer due to the loss of moisture when thawing. After cooking raw foods which were previously frozen, it is safe to freeze the cooked foods.  

Don't wait too long to transfer food from fridge to freezer

If you know you won’t be using raw meats within a few days, put them in the freezer as soon as possible to keep them from spoiling. Here's a handy guide to how long you can keep raw meat in the refrigerator.

  • Ground meat: Use or freeze within 1 to 2 days 
  • Poultry (whole or pieces): Use or freeze within 1 to 2days  
  • Roasts, steaks, or chops: Use or freeze within 3 to 5 days  
  • Fish: Use or freeze within 3 to 4 days 
  • Cooked leftovers: Use or freeze within 3 to 4 days  

Think twice before freezing these foods

While many foods freeze well, some have a proven track record of holding up poorly when frozen.

  • High-water content vegetables, such as lettuce, celery, cucumbers, and radishes, break down when frozen.  
  • Potatoes may darken and change texture when included in soups and stews.  
  • Half-and-half, sour cream, mayonnaise, and cottage cheese often become grainy or watery when frozen separately and not as an ingredient incorporated into other foods.
  • When frozen alone, cooked pasta products lose texture.
  • Gelatin and gelatin dishes weep when thawed.
  • Cooked egg whites become tough and rubbery.

Find answers to common questions about freezing food

Can I freeze milk?
Yes! Place into smaller airtight containers and leave an inch at the top to allow it to expand. Use within three months for best quality.  

Can I freeze eggs? 
Eggs can be stored in the refrigerator for at least one month. To store longer, crack eggs and mix the yolks with the whites. To prevent graininess, add 1 tablespoon sugar or 1⁄2 teaspoon salt per one cup of egg mixture. Strain through colander to improve uniformity. Allow an inch at the top of the container. Do not freeze eggs in the shell.  

Can I freeze cheese? 
Yes, you can freeze hard and semi-hard cheeses. For best results shred cheese or slice into small pieces before freezing. Cheese food products, such as sauces, dips, and processed cheeses usually freeze fine. Soft cheeses do not freeze well.  

Can I freeze bread? 
Yes! For commercial packaged bread or homemade bread, place in a heavy-duty freezer bag and freeze for up to 3 months for best quality.
