Freezing Soup: Plastic Bags, Safe?

can soup be frozen in plastic bags

Freezing soup is a great way to preserve leftovers or prepare for busy weeknights when there's no time to cook. It is possible to freeze soup in plastic bags, but there are a few things to consider. Firstly, it is important to let the soup cool to room temperature before transferring it to the bags to avoid increasing the temperature inside the freezer, which can affect other stored items. Secondly, when using plastic bags, it is recommended to use freezer-safe, BPA-free, gallon or quart-sized zip-top bags to maintain freshness and prevent freezer burn. Thirdly, laying the bags flat in the refrigerator or freezer optimizes space and makes thawing more manageable. Finally, while plastic bags are convenient, some people prefer to limit their plastic usage due to environmental and potential health concerns associated with low temperatures deteriorating the plastic. Alternatives include using reusable containers or ice cube trays for freezing soup.

Freezing soup in plastic bags vs. containers

Freezing soup is a great way to preserve your favourite recipes and ensure you always have a delicious meal ready to heat and serve. But what is the best way to freeze soup—in plastic bags or containers?

Freezing Soup in Plastic Bags

Freezing soup in plastic bags can be a convenient option if you're looking to save space in your freezer. Plastic bags, such as gallon-sized zip-top bags, are flexible and can be laid flat or stacked like records, maximising freezer real estate. They are also relatively inexpensive and can be purchased in freezer-safe varieties to maintain freshness. However, some people find the process of filling liquid soup into bags messy and prefer the structure of containers. Plastic bags can also be prone to freezer burn and may raise environmental and health concerns due to the use of plastic.

Freezing Soup in Containers

Rigid plastic containers or reusable silicone moulds are another popular option for freezing soup. They are easy to fill and provide a stable structure for storing frozen soup. Containers with flat bottoms and straight sides can be conveniently stored in the freezer and are microwave-safe for reheating. It's important to choose BPA-free plastic containers and ensure you leave about an inch of headspace as liquids expand when frozen. While containers may occupy more freezer space, they can be more manageable for portion control and inventory management when properly labelled.

The decision to freeze soup in plastic bags or containers ultimately depends on your personal preferences and considerations. Plastic bags offer space-saving flexibility and convenience, but may pose environmental concerns and present challenges during the filling process. Containers, on the other hand, provide structure and stability, making them easier to fill, store, and reheat. They are a good choice for portion control and inventory management but may require more freezer space. By understanding the advantages and disadvantages of each method, you can choose the best option for freezing and enjoying your favourite soups.

How to prepare soup for freezing in bags

Preparing soup for freezing in bags is a great way to save space in your freezer. Here is a step-by-step guide:

Cool the Soup:

Before transferring the soup to bags, it is important to let it cool down to room temperature. This is crucial to avoid increasing the temperature inside your freezer, which can affect other stored items. Place your pot of soup in a sink filled with cold water and ice, stirring occasionally, to speed up the cooling process.

Choose the Right Bags:

Select sturdy, freezer-safe plastic bags designed for freezing food. Look for zip-top bags that can be sealed airtight. These bags are ideal for stacking and storing efficiently in your freezer.

Portioning:

Freeze your soup in individual or family-sized portions. This way, you can easily thaw and reheat the exact amount you need. For a quart-sized bag, portion out about 2 to 3 cups of soup. For a gallon-sized bag, use approximately 3 quarts or 12 cups.

Filling the Bags:

Place each bag in a container, such as a measuring cup, and use your hand to hold it open. Use a ladle or measuring cup to fill the bag with cooled soup. Remember to leave about an inch of headspace or extra room in each bag, as liquids expand when frozen. Press out as much air as possible from the bag before sealing it shut.

Labelling:

Clearly label each bag with the type of soup, the date it was frozen, and any other relevant information. This helps you manage your frozen meals and ensures you consume the soup within an optimal period.

Freezing:

Lay the filled bags flat in a single layer on a baking sheet or the floor of your freezer. Freeze for 12-24 hours until the soup is completely solid. Once frozen, you can remove the baking sheet and stack the bags upright like books on a shelf for easy storage and access.

Now you know how to prepare and freeze soup in bags! It is a convenient method to preserve your favourite soups for future meals.

Pros and cons of freezing soup in plastic bags

Freezing soup in plastic bags has its advantages and disadvantages.

Pros

Plastic bags are a great way to save space in your freezer. They are flexible and can be laid flat or stacked, making them an efficient use of freezer space. Bags are also cheap and convenient, and you can easily portion out your soup into individual servings.

Cons

The process of getting liquid soup into bags can be messy, and it is difficult to fill the bags without spilling. Plastic bags are also bad for the environment and potentially your health, as low temperatures can cause the plastic to deteriorate. Bags are also more prone to freezer burn and can be messy when defrosting.

Some people prefer to freeze soup in containers and then transfer the frozen soup to bags to save space and avoid buying lots of containers. However, this can be a hassle, and it is recommended to wrap the frozen soup in plastic wrap before placing it in a bag to protect it from freezer burn.

Overall, freezing soup in plastic bags can be a convenient and space-saving option, but it has potential drawbacks related to the environment, health, and messiness.

Best types of soups to freeze in plastic bags

Yes, you can freeze soup in plastic bags. It is recommended to use freezer bags to save space and these are safe for freezing. However, some sources suggest that freezing in plastic bags can be messy and that plastic is not great for the environment or our health.

Now, here are some tips on the best types of soups to freeze in plastic bags:

Broth-based soups, stews, and chilis freeze well. You can also freeze stock, which can be used as a base for recipes. Chicken broth, beef broth, and vegetable stock are all good options. If you are freezing broth-based soups, use medium-high heat to reheat them on the stovetop.

Soups that are just broth or puréed will freeze the best. Soups with beans, noodles, rice, or large pieces of vegetables will become mushy once thawed. If you are freezing soups with beans or vegetables, use medium heat to reheat them on the stovetop and watch them closely to prevent burning.

When freezing soup in plastic bags, it is important to let the soup cool to room temperature before freezing. Leave about an inch of headspace in the bag, as liquids expand when frozen. Label the bag with the type of soup and the date it was frozen. Freeze the soup for 12-24 hours, and store it in the freezer for up to three months.

How to defrost and reheat frozen soup from plastic bags

Yes, soup can be frozen in plastic bags. It is recommended to use freezer-safe containers such as plastic freezer bags or rigid plastic containers. However, some sources suggest that freezing in plastic bags can be messy and is not environmentally friendly.

Defrosting:

  • It is recommended to thaw frozen soup in the refrigerator overnight. This is a safe method to ensure the soup reaches the desired temperature.
  • Alternatively, you can place the frozen soup bag under hot running water to loosen it up and then transfer the soup to a bowl or saucepan for further thawing.
  • If you plan ahead, you can leave the frozen soup bag on the counter to thaw at room temperature. This method may take several hours, depending on the volume of soup.
  • For a quicker option, fill your sink or a large bowl with hot water and place the frozen soup bag into it. This will help speed up the defrosting process.

Reheating:

  • Once the soup is thawed, you can reheat it on the stovetop or in a microwave.
  • For stovetop reheating, use medium-high heat for broth-based soups and medium heat for purees or stews. Stir frequently to prevent burning and keep an eye on any beans or vegetables in the soup.
  • If using a microwave, transfer the thawed soup to a microwave-safe bowl and heat in short intervals, stirring in between, until the soup reaches your desired temperature.
  • If the soup is still frozen solid, add a couple of tablespoons of water to the bowl before microwaving. This will create steam and help thaw the soup while preventing it from sticking to the bowl.

Please note that it is important to stir the soup occasionally during reheating, regardless of the method, to ensure even heating and maintain the soup's texture.
