Freezing soup without plastic is a great way to reduce your environmental impact and avoid the health risks associated with plastic containers. Plastic containers and bags can leach harmful chemicals into your food, even when stored in the freezer. To freeze soup without plastic, you can use glass jars, stainless steel containers, or even milk cartons. Glass jars are perfect for freezing soups, stews, and sauces, but remember to leave some space at the top to prevent breakage as liquids expand when frozen. Stainless steel containers are easy to clean, keep your food fresh, and lock in nutrients, but they should never be used in the microwave. Reusable beeswax food bags and silicone freezer bags are also great alternatives to plastic.

What You'll Learn
Glass jars are perfect for freezing soup
When using glass jars for freezing soup, it is important to remember that liquids expand when frozen, so be sure to leave some space at the top of the jar to prevent breakage. You can also freeze the soup with the lid off, and then add a small amount of water to the top of the frozen soup to create a seal. Just remember to rinse the water off before defrosting.
Glass jars are also great for storing other liquids like sauces and broths, as well as for freezing fruits and vegetables. They are transparent, so it is easy to see what is inside, and they come in various sizes, making it convenient to store different portion sizes.
However, one downside of glass jars is their potential for breakage, especially when transferring between different temperatures. It is important to use sturdy jars and avoid overfilling to minimize this risk. Additionally, some glass jars have plastic lids, which may not be suitable if you are aiming for a completely plastic-free storage solution.

Leave room for liquids to expand in glass containers
Glass containers are a great way to store food in the freezer without using plastic. Glass is microwavable, dishwasher-safe, and freezable. However, when freezing liquids in glass, it is important to leave some room at the top of the container. This is because liquids expand when they freeze, and the glass will break if there is no room for the liquid to expand.
When freezing liquids in glass, it is recommended to leave approximately one inch of space at the top of the container. This allows for the expansion of the liquid as it freezes. If the container is filled to the brim, the glass may break as the liquid expands. It is also important to use sturdy glass containers, such as thick Pyrex or mason jars, to avoid breakage.
For those who prefer to freeze their liquids with a lid, it is recommended to leave the lid off during the initial freezing process. After the liquid has frozen, you can add about half an inch of water to the container and then seal it. This creates a water seal that further preserves the contents. When you are ready to defrost and use the frozen liquid, simply rinse off the water seal with warm water.
It is worth noting that some glass containers come with plastic lids. If you are looking to eliminate plastic altogether, you can opt for brands that use alternative materials, such as rubber and metal, to secure their lids. Additionally, when freezing liquids in glass, it is important to avoid extreme temperature changes. Allow the container to thaw slowly to prevent thermal shock, which can cause the glass to crack or shatter.
By following these simple guidelines, you can successfully freeze liquids in glass containers without plastic. Leaving adequate room for expansion, using sturdy containers, and being mindful of temperature changes will ensure the safe and effective freezing of your liquids without the need for plastic.

Stainless steel containers are a good alternative
When selecting a stainless steel container, opt for airtight options to ensure your soup stays fresh for longer. Some containers feature a silicone ring to enhance watertightness. While these containers are durable, it is advisable to leave some space at the top to prevent warping.
Stainless steel containers are available in various sizes, making them suitable for freezing different portions. They are ideal for larger items like meat, providing more space than traditional jars. Additionally, their sturdiness makes them less prone to breakage compared to glass alternatives.
When freezing soup in stainless steel containers, it is essential to leave some space at the top, as the liquid will expand when frozen. This precaution prevents the container from warping or becoming damaged. Always follow the manufacturer's instructions and guidelines for the specific stainless steel containers you choose to use.
