HOW-TO & PRACTICAL

Which foods should you never put in the freezer?

Last updated:

Some foods should not be frozen because freezing damages their texture, flavor, or safety. These include eggs in shells, soft cheeses, fresh herbs, and certain produce like lettuce and tomatoes.

Cooked potatoesDevelop a mushy, grainy texture when frozen

Foods That Change Texture

Many foods become mushy, watery, or unpleasantly soft after freezing because ice crystals rupture cell walls. Raw vegetables with high water content like lettuce, cucumbers, and tomatoes become soggy and lose their crisp texture. Cooked potatoes also turn mushy when frozen and thawed. These foods are best consumed fresh rather than frozen.

Dairy and Cheese Products

Soft cheeses like cream cheese, ricotta, and feta become grainy, crumbly, and separate when frozen. Mayonnaise-based condiments and dressings also separate into an unappealing consistency. Hard cheeses freeze better than soft varieties. It is best to keep these items refrigerated rather than frozen.

Eggs and Egg Products

Raw eggs in their shells should never be frozen because the liquid inside expands and cracks the shell, allowing bacteria to enter. This creates a food safety risk. However, beaten eggs without shells can be frozen successfully if needed. Scrambled eggs and omelets also freeze poorly and become rubbery.

Fresh Herbs and Seasonings

Other Foods to Avoid Freezing

Fried foods become soggy and lose their crispiness. Battered items separate and develop an unpleasant texture. Canned foods should not be frozen in their original containers because the expansion can burst the can. Some bakery items like cream pies and custard-filled pastries also freeze poorly due to their fillings.
