Vacuum sealing soup offers numerous advantages for both home cooks and meal preppers alike. Here are some key benefits:
1. Extended Shelf Life
One of the most significant advantages of vacuum sealing is the extended shelf life it offers. By removing air from the packaging, you can keep your soup fresh for weeks or even months.
2. Space Efficiency
Vacuum-sealed soup takes up less space than traditional storage methods. This is particularly beneficial for those with limited freezer space, as vacuum sealing allows you to stack and organize your items effectively.
3. Flavor Preservation
Vacuum sealing helps maintain the integrity of flavors in your soup. By keeping out air, the soup retains its taste and prevents freezer burn, which can alter the flavor profile.
Can You Vacuum Seal Soup? The Answer is Yes!
Now, let’s address the primary question: can you vacuum seal soup? The straightforward answer is yes, but there are a few caveats and best practices to follow.
Considerations Before Vacuum Sealing Soup
Before jumping into the vacuum sealing process, there are several important considerations to keep in mind:
1. The Right Type of Soup
Not all soups are created equal when it comes to vacuum sealing. Cream-based soups, for example, can separate and become unappetizing when thawed. Additionally, chunky soups might have larger pieces that can puncture vacuum bags. It’s best to opt for smooth, broth-based soups for vacuum sealing purposes.
2. Cooling the Soup
Vacuum sealing hot food can cause bags to steam up, creating a less effective seal. Therefore, it’s essential to allow the soup to cool to room temperature before vacuum sealing.
3. Suitable Vacuum Sealers
Not all vacuum sealers are designed to handle liquids like soups. Consider investing in a vacuum sealer that features a “liquid mode” or a pulse setting that can efficiently deal with softer foods.

2. Water Bath Thawing
If you’re in a hurry, you can place the vacuum-sealed bag in a cold water bath, changing the water every 30 minutes until thawed.
3. Direct Reheating
If using a vacuum container, you can often reheat the soup directly in the container. Just make sure that the container is microwave-safe.
Addressing Safety Concerns
While vacuum sealing soup can significantly extend its shelf life, it’s essential to follow safety guidelines to prevent any foodborne illnesses.
1. Food Safety Temperatures
To ensure your soup is safe for vacuum sealing and storage, make sure it has cooled to room temperature within two hours after cooking. This minimizes the risk of bacterial growth.
2. Freezer Duration
Vacuum-sealed soup can last in the freezer for up to 6 months. While it might still be safe to eat beyond this time frame, the quality may decline.
3. Signs of Spoilage
Always check for any signs of spoilage before consuming vacuum-sealed soup. Common signs include off-smells, unusual colors, or the presence of ice crystals inside the bag, indicating freezer burn.
Final Thoughts
Vacuum sealing soup is not only possible but also an excellent method to enhance your food preservation efforts. By following the outlined steps and considering safety guidelines, you can enjoy the convenience of homemade soups at any time. Whether you’re meal prepping, reducing waste, or just looking to keep your favorite varieties on hand, vacuum sealing is a game changer in the realm of soup storage.
From enhanced flavor to easier storage, the benefits of vacuum sealing soups are too good to ignore. So next time you whip up a batch of your favorite concoction, remember that with a little patience and the right techniques, you can enjoy your comforting soups long after you’ve created them. Happy sealing!
Can you vacuum seal soup?
Yes, you can vacuum seal soup, but it’s essential to follow specific guidelines to ensure safety and preserve the quality of the soup. First, allow the soup to cool completely before attempting to vacuum seal it. This helps to prevent steam from creating excess pressure inside the vacuum bag, which can lead to leaks.
Once cooled, it’s best to store the soup in a rigid container or use freezer-safe, resealable bags designed for liquids. If using a vacuum sealer, remember to leave enough space at the top of the bag to account for the expansion of liquids during freezing.
What is the best way to vacuum seal soup?
The best way to vacuum seal soup is to first freeze it in portion-sized amounts. Pour the cooled soup into freezer-safe containers or bags, ensuring that you leave some space for expansion. Freeze the soup until it’s solid, which typically takes several hours. Once frozen, you can then vacuum seal the portions easily without worrying about liquid spillage.
Alternatively, if you don’t want to freeze the soup first, you can use a vacuum sealer that is capable of handling liquids. In this case, seal the soup at a lower setting to minimize the suction that might pull liquid into the vacuum sealing machine. This method may be less common, but it can be effective if done carefully.
Is it safe to vacuum seal hot soup?
Vacuum sealing hot soup is not recommended due to safety and quality concerns. When hot soup is sealed, steam can create pressure that may cause the seal to break or lead to spills. Additionally, sealing hot food can create a breeding ground for bacteria if the food does not cool quickly enough, which can pose health risks.
To ensure safety, allow your soup to cool to room temperature before sealing it. You can also speed up the cooling process by placing the soup in an ice bath or dividing it into smaller portions. This way, you can vacuum seal the soup while maintaining both quality and food safety.
What type of vacuum sealer is best for liquids like soup?
There are two main types of vacuum sealers to consider when sealing liquids like soup: chamber vacuum sealers and external vacuum sealers. Chamber vacuum sealers are typically the best option for liquids because they remove air from the entire chamber, minimizing the risk of liquid being drawn into the machine. These sealers tend to be more expensive and are commonly used in commercial settings.
External vacuum sealers can also be used for liquids but require extra care. Some models come with a manual setting that allows you to control suction power, which is helpful for sealing liquid items. If using an external sealer, choose one designed for moist foods, and ensure you leave enough space at the top of the bag when sealing.
How long can vacuum-sealed soup be stored?
Vacuum-sealed soup can typically be stored for 1 to 3 years in the freezer, but its quality may diminish over time. Properly vacuum sealing soup helps to prevent freezer burn and maintain flavor. Always label your vacuum-sealed bags with the date and contents to keep track of how long they have been stored.
In the refrigerator, vacuum-sealed soup can last up to a week, depending on the ingredients. Soups with high acidity or those containing dairy may have a shorter shelf life. It’s important to use your best judgment when evaluating the freshness of any stored food.
Can you reheat vacuum-sealed soup?
Yes, you can reheat vacuum-sealed soup, but it’s crucial to do so safely. If the soup is frozen, consider transferring it to a pot and gently heating it on the stove. You can also thaw it overnight in the refrigerator before reheating. If you’re using a microwave, be sure to remove the soup from the vacuum-sealed bag, as plastic bags may not be microwave-safe.
When reheating, ensure that the soup reaches a safe temperature of at least 165°F (74°C) to kill any potential bacteria. Stir the soup while heating to promote even warming, and check for any hot spots to avoid burns from overly hot sections.
