Vacuum sealing is one of the best ways to keep food fresh longer, reduce waste, and organize your kitchen — but when it comes to liquids, most people run into the same problem:
“Every time I try sealing soup or sauce, it gets sucked into the machine!”
If you’ve experienced this, you’re not alone. It’s one of the most asked questions online — on Reddit, Google, and cooking forums. The good news?
Vacuum sealing liquids is possible, and it’s actually easy — as long as you use the right method.
Here is the complete guide on how to vacuum seal soups, sauces, broths, stews, smoothies, curries, and any liquid without making a mess.
Why Vacuum Sealing Liquids Is Tricky
When the vacuum pump removes air from the bag, it also tries to pull out anything loose inside — including:
-
Liquids
-
Steam
-
Oils
-
Moisture
This causes:
-
Messes inside the machine
-
Weak or failed seals
-
Leaking bags
-
Bacteria risk if food is sealed while hot
This is why liquids need a slightly different approach.
Method #1 (Most Reliable): Freeze First, Then Vacuum Seal
This is the method recommended most often on Reddit — and it works perfectly with your Chef Preserve Vacuum Sealer.
How to do it:
-
Pour the liquid into the vacuum bag.
Fill only 50–70% of the bag. -
Lay the bag flat in the freezer.
Freeze for 1–2 hours, just until it becomes firm. -
Once the liquid is semi-solid, place it back in the vacuum bag (if needed).
-
Vacuum seal it normally.
Now the pump pulls out air without sucking up any liquid.
Why this works
-
Frozen or semi-frozen liquids stay in place
-
No moisture reaches the seal
-
The bag seals perfectly
-
Cleaner, safer, and more airtight
Best for:
-
Soups
-
Sauces
-
Broths
-
Smoothies
-
Stews
-
Chili
-
Curries
-
Mashed foods
-
Anything runny
This method is simple, safe, and prevents 100% of the mess.
Method #2: Use Vacuum-Seal Containers (Clean, Easy & Reusable)
If you want the easiest way to vacuum seal liquids — no freezing, no mess —
use special vacuum-seal containers.
👉 You can mention that we also sell these containers, designed for this exact purpose.
How it works:
-
Pour your liquid inside the container.
-
Lock the lid.
-
Place the vacuum sealer on the air valve.
-
Press the button — the air gets sucked out without touching the liquid at all.
Why containers are great:
-
No leaking
-
No freezing required
-
Perfect for large batches
-
Ideal for meal prep
-
100% reusable
-
Stackable and organized
-
No disposable bags needed
-
Works with hot or cold food (just don’t seal boiling liquid)
Perfect for:
-
Weekly soup portions
-
Sauces & dressings
-
Marinades
-
Cut fruit in juice
-
Meal-prep broths
-
Leftover stews
-
Baby food
-
Coffee concentrates
-
Overnight oats
For many customers, containers become their favorite vacuum-sealing method for liquids.
What About Hot Food?
Never vacuum seal hot liquids.
Why?
-
Steam prevents a proper seal
-
Creates pressure inside the bag
-
Moisture weakens the bag
-
Increases bacteria risk
Always let liquids cool for 20–30 minutes before sealing — even if you’re using containers.
How Long Do Vacuum-Sealed Liquids Last?
In the fridge:
-
Soups: 7–10 days
-
Broths: 10–14 days
-
Sauces: 7–14 days
-
Smoothies: 3–5 days
-
Stews & chili: 7–10 days
In the freezer (vacuum sealed):
-
Soups: 1–2 years
-
Broths: 1–2 years
-
Sauces: 1 year
-
Stews: 1 year
-
Smoothies/purees: 8–12 months
Vacuum sealing dramatically extends freshness by preventing freezer burn and oxidation.
Pro Tips for Perfect Results
✔ Leave space at the top
Liquids expand when frozen.
✔ For bags: freeze flat
You get freezer-friendly “soup bricks” — easy to stack.
✔ Label the bags/containers
Include date + contents.
✔ Don’t overfill
Keep 3–4cm of space near the seal.
✔ For stews: strain first
Seal the solids, freeze the liquid separately.
Conclusion
Vacuum sealing liquids doesn’t have to be messy.
With the right method, you can store soups, stews, sauces, marinades, smoothies, and more — cleanly and safely.
Two ways to do it perfectly:
-
Method 1: Freeze the liquid first for a perfect bag seal.
-
Method 2: Use vacuum-seal containers (which we also offer) for the easiest, cleanest, reusable solution.
Either way — your food stays fresher longer, tastes better, and you save money every week.
