Keeping Soups & Stews Fresh: The Complete Guide to Vacuum Sealing Soup
Hey there! If you‘re like me, you love preparing big batches of hearty soups and stews, but struggle to keep leftovers fresh. Vacuum sealing is hands-down the best way I‘ve found to store soup and extend its shelf life. In this guide, I‘ll share everything I‘ve learned about getting the most out of vacuum sealed soups and stews.
Why Vacuum Sealing Works So Well for Soup
Vacuum sealing pumps out all the air surrounding food before sealing it in an airtight bag or container. This anaerobic (air-free) environment dramatically slows down spoilage and bacteria growth.
Why is this especially effective for soups and stews? A few reasons:
- Prevents evaporation – Vacuum sealing locks in moisture, so soups stay nutrient rich
- Inhibits mold – With no air, mold can‘t grow!
- Halts oxidation – No air means less oxidation that leads to off-flavors
- Deters bacteria – Anaerobic environment makes it harder for bacteria to thrive
- Saves space – Vacuum bags take up less room than rigid containers
On average, vacuum sealing gives soup 5-8X longer shelf life compared to conventional storage methods. Pretty amazing, right?
Now let‘s dive into the details on vacuum sealing various types of soups and stews…

Shelf Life Chart: How Long Soups Last When Vacuum Sealed
Want to know how long your soup will really last vacuum sealed? Here‘s a handy shelf life comparison chart for different types of soups and stews:
| Soup/Stew Type | Fridge (Vacuum Sealed) | Freezer (Vacuum Sealed) |
|---|---|---|
| Hearty Vegetable | 3-6 months | 6-12 months |
| Minestrone | 3-6 months | 6-12 months |
| Chicken Noodle | 3-6 months | 6-12 months |
| Potato | 3-6 months | 6-12 months |
| Tomato-based | 3-6 months | 6-12 months |
| Creamy Dairy-based | 2-3 months | 4-6 months |
| Seafood chowder | 2-3 months | 4-6 months |
| Meat-based with pasta/grains | 1-2 months | 3-4 months |
As you can see, vacuum sealing can keep soups fresh for months longer than refrigeration alone. But not all soups have equal shelf life – creamy and seafood chowders don‘t freeze as well. Meat and pasta-heavy soups also tend to deteriorate faster.
For optimal taste and texture, I recommend consuming most soups within 1-2 months of vacuum sealing. But they‘ll remain safe to eat for much longer when properly stored!
Tips for Maximizing Soup Freshness
To get the longest shelf life from your vacuum sealed soups, here are my top tips:
- Cool completely before sealing – Seal soups at room temp or chilled
- Portion into servings – Smaller bags thaw faster than one big one
- Press out air – Manually press out excess air before sealing
- Seal tightly – Double seal end of bag for a tight closure
- Label contents/date – Lets you know what‘s inside and when it was sealed
- Freeze ASAP – Freeze sealed soups right away for best quality
- Store in cool/dark spot – Heat and light degrade soup over time
- Inspect seal integrity – Look for air leaks or openings where air could get in
Following these best practices will ensure your soups stay fresher for as long as possible!
Vacuum Sealing Soup in Mason Jars
While vacuum bags are ideal, you can also vacuum seal soups and stews in wide-mouth Mason jars using a bit of a special technique:
- Lower jar halfway into vacuum sealer water bath
- Initiate vacuum cycle to seal on lid
- Submerge rest of jar to create full seal
- Label jar with contents & date
This gives an extra-tight seal that keeps soup fresh for 6-8 months stored in the pantry or fridge. I like using jars for thicker stews that don‘t pour as easily into bags.
Just keep in mind, you can only vacuum seal wide-mouth jars – standard jars don‘t work with this technique. And be sure to leave 1 inch of headspace at the top so food has room to expand as it freezes.
Choosing the Best Vacuum Sealer for Soup
Investing in a high-quality vacuum sealer designed for liquid foods really pays off. Here are the key features I recommend looking for:
- Removable drip tray – Catches drips and spills for easy cleanup
- Pulse mode – Allows you to vacuum in bursts to prevent crushing soft foods
- Moist/liquid setting – Optimized pressure for soups and thin liquids
- Wide sealing strip – Creates a sturdy, airtight seal across bag
- Chamber design (optional) – Allows sealing Mason jars and marinating foods
Some of my favorite soup-friendly vacuum sealer brands are Foodsaver, NutriChef, and Weston. Expect to spend $150-$300 for a vacuum sealer with the above capabilities.
Step-By-Step Guide to Vacuum Sealing Soup
Sealing up soup is easy once you get the hang of it. Just follow these simple steps:
- Allow soup to fully cool until just warm or at room temp
- Pour soup into vacuum sealer bag, leaving 1-inch headspace
- Manually press out excess air and flatten bag
- Seal one end of bag with vacuum sealer
- Place open end inside vacuum chamber
- Initiate "Moist Food" vacuum cycle
- Seal open end of bag
- Label bag with contents and freeze or refrigerate ASAP
And that‘s it – you‘ll have perfectly vacuum sealed soup ready for the freezer. I like to lay bags flat in the freezer so they freeze faster.
What Not to Vacuum Seal
Vacuum sealing is a game changer for soup storage, but it‘s not suitable for all foods. Avoid sealing:
- Fatty foods like oil, butter, nuts – Can leave oily residue
- Carbonated drinks – Bottles may explode under pressure
- Baked goods with crumbs – Can suck crumbs into sealer
- Leafy greens, herbs – Will be crushed and wilt faster
- Very moist foods – Can be sucked into vacuum chamber
Stick to soups, stews, cooked meats, stocks, and marinades for best vacuum sealing results.
Reheating & Food Safety Tips
To safely enjoy your vacuum sealed soups:
- Thaw overnight in fridge before reheating
- Bring to a rolling boil – This kills any bacteria present
- Cook for 2-3 minutes once boiling to ensure safety
- Check internal temp reaches 165°F with a food thermometer
- Avoid "danger zone" temps between 40-140°F when thawing or reheating
Always cook raw ingredients like meat and eggs thoroughly when reheating for food safety.
Creative Soup Recipes Perfect for Vacuum Sealing
To take advantage of vacuum sealing, look for soups and stews with sturdy ingredients that freeze well. Here are some of my favorite recipes:
- Hearty Minestrone – Packed with veggies & beans
- Chicken Tortilla Soup – Just thaw & serve
