Plastic, glass, and silicone are all suitable for freezing soup, though glass and silicone will likely last longer.
The best types of containers for freezing soup are reusable glass, freezer-safe containers. However, if you are gifting soup, you can also use freezer-safe gallon-size plastic bags or Tupperware.

If using glass containers, be sure they're made of tempered glass that can be frozen. If you're using any type of plastic, be sure it's BPA-free. I especially love freezing soup flat in zip-top gallon-sized bags, as I feel it's a more efficient use of (very precious) freezer real estate.
Glass containers, in contrast, are toxin-free, easier to clean, and safe for freezing and heating. Choosing glass food storage containers helps reduce exposure to environmental toxins, which is crucial for overall health and reducing the risk of chronic illness.
Room can be left in containers to account for this expansion but it is not always able to prevent damage to a container. Polypropylene and PVC are both plastics that are brittle at temperatures below freezing. Polystyrene is considered brittle at 68°F and is very brittle at temperatures below freezing.
In reality, glass has no freezing point. It's solid and for that reason, technically can't be frozen. Still, if you want to chill a glass for your cocktail, a temperature of 32°F/0°C, or even a little colder should be enough. Naturally, it's a matter of personal preference.
When freezing soup, you can use whatever container you want as long as it's safe for the freezer and you leave the headspace as noted above. You can use freezer-safe containers made of plastic or glass as well as freezer-safe bags. There are also handy silicone freezing trays available made specifically for soup.
Freezing soup with milk or cream in it.
Soups that contain milk or cream, like chowders and bisques, also don't hold up well in the freezer — they tend to take on a grainy texture and separate when defrosted and rewarmed.
To thaw your soup, we recommend putting it in the refrigerator overnight or placing it in a bowl or pot on the counter for an hour. If you have frozen your soup in Souper Cubes, we recommend popping the soup cube out and placing it in a bowl or pot for thawing.
Our borosilicate glass products can be put into freezer and can resist till -40°c. All our borosilicate glass products have a thermal shock resistance of 220°C. That means that, if your Cook & Store dish is frozen to a maximum of -20°C then it can be put directly into an oven at a maximum of 200°C.
Jars with tapered sides or straight sides are freezer safe; shouldered jars are not.
Frozen foods remain safe indefinitely.
You can also try Souper Cubes, which are like ice cube trays but for soup servings. If you want to maximize freezer space: Ladle cooled soup into freezer-safe quart- or gallon-sized plastic bags. Freeze flat and stack once the soup is fully frozen. (This is one of our favorite freezer organization tips!)
Freeze it fast.
Lay resealable freezer bags flat on a baking sheet to create thin, stackable layers. Flat freezing speeds up the freezing process and saves precious freezer space. For containers, leave some airflow around them until the soup is frozen solid, then stack them neatly.
I generally use quart-sized Ziploc freezer bags. Don't overfill the bags: Liquids expand as they freeze, so be sure to leave a little extra room to account for this.
Naturally, many were caught off guard by this revelation, with some previously believing the brand's soups were made in-house. However, according to a Panera employee on Reddit, Panera's soups are made off-site in a factory and transported to the restaurants while frozen in pre-portioned packets.
Go for glass or something reusable like silicone. Do you need an affordable and easy-to-store option? Plastic deli-style containers are a great choice available in a variety of sizes. Plastic, glass, and silicone are all suitable for freezing soup, though glass and silicone will likely last longer.
It's a personal choice—glass is more durable and recyclable, but also more expensive. Plastic is typically budget-conscious and lightweight, but it's not exactly sustainable. Whatever your needs are, we tested the best freezer containers for soup, meal prep, and more.
They can withstand extreme temperatures without cracking or breaking. And that makes them perfect for freezer storage. However, don't introduce sudden temperature changes because that comes with a higher risk of breakage!
Keeping your soup cool in the freezer means finding the best way to freeze them for you. Here are three types of containers you can use: 1. Glass containers: You can use glass containers like mason jars to store soup so long as you protect their contents with plastic wrap.
If a jar is narrow, or has sides that taper inwards, the extra pressure placed on the glass sides as the contents freeze will make it crack (which relieves the stress).
Scratch the glass with a hard object like a key. If the scratch feels smooth, the glass is tempered.
