The short answer: yes, you can vacuum seal soup, and there are three ways to do it. With a suction vacuum sealer, freeze the soup solid first, then seal it. With a chamber vacuum sealer, seal chilled soup as a liquid, no freezing needed. With a chamber sealer deep enough for jars, stand jars of soup upright and seal them with their own lids. All three end in the same place: the refrigerator or the freezer. Vacuum sealing does not make soup shelf stable.
If your sealer just drank the broth, it is not you
You made a big pot of chili. You ladled it into a bag, clamped the bag in the sealer, and pressed the button. For a second it looked fine. Then the broth started crawling up the bag toward the machine, the seal came out wet and wrinkled, and now there is chili in the drip tray. Again.
Most people blame themselves at this point. Too full. Wrong bags. Should have pressed seal sooner.
It is none of those. It is the method. A suction vacuum sealer pulls air out through the open end of the bag, and anything that can flow goes along for the ride. Better bags and better timing do not change that. Once you see that the problem is how the air leaves, the three fixes below make sense.
Why a suction sealer pulls liquid, and why a chamber sealer does not
A suction sealer clamps the mouth of the bag and pulls. The pressure at the opening is lower than the pressure in the rest of the bag, so everything in the bag gets pushed toward the opening. Fine for a steak. With soup, the liquid reaches the seal area before the air is gone, and a wet seal is a weak seal.
A chamber vacuum sealer puts the whole pouch inside a sealed chamber and lowers the pressure in the entire chamber at once. Here is the one sentence that matters: the pressure is the same inside the pouch and outside it, so nothing pushes the liquid toward the opening. The soup just sits there while the air leaves. Then the seal bar closes the pouch, air returns to the chamber, and the pouch pulls tight.
More on the two designs: suction vacuum sealers versus chamber vacuum sealers and the guide to chamber vacuum sealing.
| Method 1: freeze first, suction sealer | Method 2: chamber sealer, pouches | Method 3: chamber sealer, jars | |
|---|---|---|---|
| Best for | Soup or stock a few times a year | Wet food every week: soup, stock, marinade, sous vide | Broth and stock by the pot, stored in glass |
| Seal it as a liquid? | No. Freeze it solid first | Yes, once it is chilled | Yes, once it is chilled |
| What you need | The sealer you already own, textured bags, freezer space | A chamber sealer and smooth chamber pouches | A chamber sealer deep enough for jars to stand up |
| Where it goes after | Freezer | Refrigerator or freezer | Refrigerator or freezer |
First, for every method: cool the soup the right way
We make vacuum sealers. We are not food safety experts, so here is what the people who are say, in their words.
The USDA Food Safety and Inspection Service says: "To prevent bacterial growth, it's important to cool food rapidly so it reaches as fast as possible the safe refrigerator-storage temperature of 40° F or below. To do this, divide large amounts of food into shallow containers. A big pot of soup, for example, will take a long time to cool, inviting bacteria to multiply and increasing the danger of foodborne illness. Instead, divide the pot of soup into smaller containers so it will cool quickly."
The same page adds: "Hot food can be placed directly in the refrigerator or be rapidly chilled in an ice or cold water bath before refrigerating." And on timing: "Within 2 hours of cooking food or after it is removed from an appliance keeping it warm, leftovers must be refrigerated."
The FDA gives the target temperatures: "Keep the refrigerator temperature at or below 40° F (4° C)" and "The freezer temperature should be 0° F (-18° C)."
There is a practical reason to chill soup too. When pressure drops, liquids boil at a lower temperature, so warm soup in a chamber sealer can bubble up and make a mess. A long vacuum cycle and high elevation make it more likely. It is not cooking anything. Chill it in the refrigerator first, then seal.
Method 1: freeze it first, then seal it with a suction sealer
This works. If you only seal soup now and then, it is the right answer, and you do not need a new machine.
- Cool the soup first, then portion it into freezer-safe containers or stand open bags upright in a loaf pan.
- Freeze until the soup is solid all the way through.
- Move the frozen block into a textured vacuum sealer bag, or leave it in the bag you froze it in.
- Vacuum and seal as you would any solid food. Nothing is liquid, so nothing gets pulled toward the machine.
- Label the bag and put it straight back in the freezer.
Freeze in flat, shallow portions so the blocks stack and you never thaw more than you need.
The trade-off is time and planning. The soup goes into the freezer, comes back out hours later, gets sealed, and goes back in. It also only works for food headed to the freezer. It does nothing for marinade you want to use tonight or stock that is going in the refrigerator. For seasonal ideas, see our fall soups post. For what should not be vacuum sealed at all, see foods you should not vacuum seal.
Method 2: seal it as a liquid with a chamber vacuum sealer
This is the method that fixes the cause instead of working around it.
- Chill the soup in the refrigerator first. Warm liquid can bubble up under vacuum.
- Fill a chamber pouch no more than about half full, so the liquid sits well below the seal bar.
- Lay the open end of the pouch across the seal bar with the whole pouch inside the chamber, and keep the liquid end lower than the bar.
- Close the lid and run the vacuum and seal cycle. Watch the first one through the lid. If the liquid starts to bubble, stop the cycle and seal.
- Wipe the pouch, label it, and put it in the refrigerator or freezer. Freeze pouches flat and they stack like books.
The habits that matter are small: do not overfill the pouch, keep the liquid below the seal bar, keep the whole pouch inside the chamber, and chill first.
What you get back is speed and range. Chilled soup goes into a sealed pouch in one step, then back to the refrigerator or into the freezer. Stock, brine, sauce, and curry work the same way. Meat can go into a pouch with its marinade and straight into the refrigerator, and vacuum marinating gets flavor into meat faster than a bowl does. If you cook sous vide, this is the difference between a bag with butter and aromatics in it and a bag you had to keep dry.
One owner of our USV32 chamber sealer put the payoff this way in a review on avidarmor.com: "This thing has *MORE* than paid for itself in food savings."

Method 3: stand jars upright in a chamber sealer
If you make broth or stock by the pot and would rather store it in glass, a jar is the easiest container for liquid. A jar stands up, so the broth sits at the bottom, well below the lid, through the whole cycle.
The catch is height. Most chamber vacuum sealers are only a few inches tall inside, so a pint or quart jar will not fit. We designed the JARMAX with a chamber 8.5 inches deep for exactly this reason. Six pint jars or four quart jars stand upright and seal in one cycle, using their own two-piece lids.
- Start with cool liquid. Warm liquid can bubble up under vacuum.
- Pour it into jars and leave room at the top. If the jars are going in the freezer, use straight-sided jars made for freezing.
- Set the lids on and screw the rings on loosely.
- Stand the jars upright in the chamber and run the cycle.
- Tighten the rings, label the jars, and put them in the refrigerator or freezer.
If something does spill, the JARMAX has a removable silicone liner with a pour spout. Lift it out, pour it off, wash it.
This is not canning. A vacuum sealed jar of broth has not been heated or sterilized. University of Minnesota Extension says plainly that vacuum sealing a jar does not result in the same shelf stable food that canning provides. Jars of soup, broth, and stock go in the refrigerator or freezer, every time. Our step by step guide to vacuum sealing mason jars covers the jar methods in full, and the guide to the best vacuum sealer for mason jars compares the tools. For a stock worth sealing, try this venison bone broth. If your jars hold freeze-dried food instead, see how to store freeze-dried food.
The honest objections to a chamber sealer, all in one place
If Method 2 sounds good, you are probably already listing reasons it will not work in your kitchen. Here they are.
They are heavy
True. Avid Armor chamber sealers run from 13.05 pounds for the USV1 up to 26.4 pounds for the USV32. The USV20 is 17.55 pounds. Most owners give one a permanent spot on the counter or a cart.
Will it open under my cabinets?
Check this before you buy, because the lid swings up. The USV20 is 17 inches tall with the lid open, so it opens under standard 18 inch upper cabinets. The JARMAX is a deep chamber machine and needs 25.5 inches with the lid open, so it wants an open counter, an island, or a cart.
Do I have to change oil?
No. Avid Armor's full size chamber sealers use a dry piston pump. There is no oil to buy and no oil to change. The parts that wear over time are the seal bar and the lid gasket.
The pouch size is limited
True, and it is the real trade-off. The pouch has to fit inside the chamber, so maximum pouch size runs from 10 by 10 inches up to 11 by 13 inches depending on the model. A suction sealer can make a bag of any length from a roll. If you seal whole fish or long cuts, that matters.
The pouch puffed up, or the soup started to boil
Both are normal physics. The little air left in the pouch expands as the chamber pressure drops, so the pouch swells, then collapses tight when air returns. Liquids boil at a lower temperature as the pressure drops, so bubbling means the liquid reached its boiling point inside the chamber. Three things make that more likely: warm soup, a long vacuum cycle, and high elevation, where the air pressure is already lower. It is not cooking. Chill the soup in the refrigerator first, and if it still bubbles, shorten the vacuum time.
There is a learning curve
There is, and owners say so. One USV32 owner named Neal wrote in a July 2026 review on avidarmor.com: "The vacuum is strong enough to rupture bags placed incorrectly (e.g., if the bag opening is not fully within the sealed chamber)." He also noted: "Vacuum force is adjustable, and at high levels can crush super delicate contents." Both are avoidable. Keep the whole pouch inside the chamber, and use a shorter vacuum time for delicate food. If a seal ever fails, this guide to fixing common seal issues walks through the causes.
The bags are different
They are, in a good way. Chamber sealers use smooth chamber pouches instead of textured bags, and smooth pouches cost less.
A suction sealer is the right answer if
- You seal soup, stock, or sauce only a few times a year. Freeze first and you are done.
- Most of what you seal is dry or solid: cuts of meat, cheese, vegetables, dry goods.
- You need long bags for whole fish, ribs, or jerky sticks. A roll makes any length.
- Counter space is tight and the machine has to live in a drawer.
We sell suction sealers too, and for a lot of kitchens they are the right tool. Liquid is simply the one job they were not designed for.
A chamber sealer is the right answer if
- Wet food is a weekly thing in your kitchen: soup, stock, chili, curry, brine, marinade.
- You cook sous vide and want fat, butter, or marinade in the bag.
- You batch cook and want flat, stackable freezer portions without the freeze, seal, refreeze routine.
For most home cooks making that step, the USV20 is the practical place to start: an 11.5 inch seal bar, pouches up to 11 by 10 inches, vacuum time you set yourself, and a lid that opens under standard cabinets. If your liquid lives in jars, the JARMAX has the chamber deep enough to stand them up.

From the community: sealing soups and liquids
These are community members talking about chamber vacuum sealers in general. None of these people reviewed the JARMAX. The JARMAX is new. This is how people in the community talk about this category.
I have a chamber vacuum sealer. I like it because I can do things with liquid in them. I can seal soup. can also seal stuff with liquid butter, and olive oil.
Community discussion, r/sousvide
Get a chamber vacuum sealer. It’s better in every single way except the cost. Slightly more up front but the bags are way cheaper. Plus they can seal bags of liquid.
Community discussion, r/Hunting
The best meal prep device I've ever purchased is a chamber vacuum sealer. Stews, soups and sauces are now boil-in-the-bag meals, and so easy to prep, vacuum seal and freeze.

What owners say about sealing liquids
The JARMAX is new, so these are verified buyers of our other chamber sealers, in their own words. Each one says which machine they own.
Questions people ask
Can you vacuum seal soup?
Yes, three ways. Freeze the soup solid and any vacuum sealer can seal it. Use a chamber vacuum sealer and you can seal chilled soup as a liquid. Or stand jars of soup upright in a chamber sealer deep enough for jars. Whichever you use, vacuum sealed soup is still perishable and goes in the refrigerator or freezer.
Can you vacuum seal liquids?
Yes, with the right method. A suction vacuum sealer pulls air out through the bag opening and liquid follows the air, so freeze liquids first. A chamber vacuum sealer lowers the pressure around the whole pouch at once, so the liquid stays put and you can seal it without freezing. Sealed soup, stock, sauce, and marinade still belong in the refrigerator or freezer.
Why does my vacuum sealer suck up liquid?
Because of how a suction sealer works, not because of anything you did. It pulls the air out through the open end of the bag, and anything that can flow travels with the air toward the seal area and the drip tray. Freezing the liquid first solves it. A chamber vacuum sealer avoids it entirely.
How do you vacuum seal soup without freezing it first?
Use a chamber vacuum sealer. The pressure drops evenly inside and outside the pouch, so nothing pushes the soup toward the opening. Chill the soup, fill the pouch about half full, keep the liquid below the seal bar, and run the cycle. Then refrigerate or freeze it.
What is the best vacuum sealer for liquids?
A chamber vacuum sealer. It is the type designed to seal liquid as liquid. If you seal soup or marinade a few times a year, a suction sealer plus the freeze first method is a good answer and costs less. If wet food is a weekly part of your cooking, a chamber sealer is the better tool.
Do I have to cool soup before vacuum sealing it?
Yes. The USDA says to cool food rapidly and to divide a big pot of soup into smaller containers so it cools quickly. There is a practical reason too: liquids boil at a lower temperature when the pressure drops, so warm soup can bubble up inside a chamber sealer, and a long vacuum cycle or high elevation makes it more likely. Chilled soup seals cleanly.
Why does the pouch puff up in a chamber vacuum sealer?
As the chamber pressure drops, the small amount of air left in the pouch expands, so the pouch can swell partway through the cycle. That is normal. When air returns to the chamber, the pouch collapses tight around the food.
Can you vacuum seal soup in mason jars?
Yes, in a chamber vacuum sealer deep enough for jars to stand upright, such as the Avid Armor JARMAX. The jar's own two-piece lid seals it. This is not canning. It does not heat or sterilize the soup, so the jars go in the refrigerator or freezer, never on a pantry shelf.
Does vacuum sealing soup make it shelf stable?
No. Vacuum sealing removes air. It does not cook, sterilize, or preserve food the way pressure canning does. Soup, stock, broth, and sauce must be kept in the refrigerator or freezer whether they are vacuum sealed or not.
Can you vacuum seal marinade with meat?
Yes. In a chamber vacuum sealer, meat and marinade go in one pouch and straight into the refrigerator. With a suction sealer, freeze the marinade in the bag first. Avid Armor chamber sealers also have a marinate function for an open dish inside the chamber.
