Can You Put Metal In The Freezer?
Many people hesitate to freeze food in metal, worried it may crack, rust, or damage their freezer. The truth is, metal is one of the safest options for cold storage when used correctly. High-quality stainless steel and aluminum containers handle freezing temperatures well.
The key is knowing which types of metal work, how to store food safely, and what pitfalls to avoid. Here is everything you need to know about putting metal in the freezer.
Is Metal Freezer-Safe?
Good-quality stainless steel containers are perfectly safe for freezer storage. They won't crack under cold temperatures and are more durable than glass or thin plastic. Metal containers are a great eco-friendly option since they can be reused many times.
However, poor-quality steel or aluminum may corrode, so choosing sturdy, food-grade metal is important if you want to protect your food.
Leave Space for Expansion
When freezing liquids or moist foods, always leave room at the top of the container. Water expands as it freezes, which can damage the lid or warp the container.
About half an inch of empty space is usually enough to keep the food safe and prevent leakage.
Can You Freeze Sealed Cans?
Unopened cans should never be placed in the freezer. As the liquid inside expands, the can may bulge, crack, or even burst.
If you need to freeze canned goods, be sure to transfer them into a freezer-safe metal or plastic container first so they have room to expand.
Can You Freeze Baking Pans And Ice Trays?
Metal baking pans can go straight into the freezer, which is useful when it comes to freezing casseroles or baked goods. Stainless steel ice cube trays are also safe to freeze and long-lasting.
Always cover pans and trays with foil or wrap to prevent freezer burn and odors from seeping in.
The Right Way To Use Metal In Freezers
The safest method for freezing food in metal is to use food-grade stainless steel containers with tight-fitting lids. Pairing metal with silicone seals helps prevent air exposure and freezer burn.
Avoid using cheap, thin metals that can bend or rust. With the right container, metal is one of the most reliable ways to store soups, sauces, and leftovers in the freezer.
