Vacuum Seal Liquids: Easy Method

The video below demonstrates how to vacuum seal liquids into flat packages using a basic vacuum sealer. I use a FoodSaver vacuum sealer; the rolls of plastic and bags are BPA free. I assume that other brands would work equally well.

Over the years I’ve used this technique when freezing soups, stews, sauces, tomato puree, and more. Because the liquids are frozen into flat packages, they stack nicely in the freezer and conserve space.

Some people suggest first freezing liquid into cubes, then vacuum sealing the cubes. I find that extra step to be completely unnecessary, and the resulting packages are bumpy and don’t stack as well. Freezing the liquid directly into flat packages is faster, easier, and more efficient.

I recently noticed that there are expensive vacuum sealers for sale made specifically for liquids. Again, I find my method works perfectly well without investing in a larger, more expensive machine.

Tips for Vacuum Sealing Liquids

  • The edges of your packages may become wet if liquid is drawn out during the vacuum sealing process. Simply wipe with a dish cloth and then blot dry.
  • Before freezing, be sure your packages are dry, otherwise they may stick together in the freezer. As an option, you can layer a paper towel between each package.
  • The packages will stack better if they are all the same size.

    I have a basic Ziploc vacuum sealer without the ‘Moist’ option. I added a little liquid with the food and it sucked out a lot of liquid so that it over flowed in the trough.

      Hi Crystal,

      Hummmm. Next time, try pressing “seal” if you notice liquid is being sucked out. Every so often that happens to me, and I press “seal” to stop any more from being drawn out.

      I hope this helps,
      Judy

    I just purchased my very first Food Saver after wanting one for a long time. I am so happy to have found your tutorial on freezing liquids since that was one of the main reasons I bought it for. Your instructions were clear and easy to follow. Thank you.

    its hard to see but sounds like you are not only sealing but vacuuming out the excess air correct? How does it not suck the liquid up and prevent the seal? I have a nutrichef and the liquid gets sucked up past the seal line and it doesn’t fully seal. it would be helpful to see the sealing and vacuuming by filming the video right above the sealer instead of from the side. Thank you

      Hi David. Yes, after nudging out any trapped air bubbles, the air from the edge of the bag is sucked out before being sealed. Most of the time the machine starts sealing before any liquid is sucked out. Occasionally a bit of liquid is sucked out, but not enough to prevent a seal. Afterwards I just wipe the edge.

    I love my food safer but my freeze dryer has been a life changer. You should look into one.

      Hi Sandy,

      I did a quick google search. Wow they’re expensive – about twice as expensive as my 10 tray Excalibur with stainless steel shelves.

      Are you saying that you freeze dry sauces and soups?

        a freeze dryer will run you about $2,500+ and yes it will preserve soups, sauces, and most other foods for 25 years without loosing nutrition like we see with other methods.
