What You’ll Need
Before getting started, ensure you have all the necessary supplies. Here’s what you’ll need:
Essential Equipment
- Foodsaver Vacuum Sealer: A Foodsaver model with a jar sealer attachment is essential for this process.
- Mason Jars: Choose the size appropriate for your needs – pint, quart, or half-gallon jars are all excellent options.
- Jar Lids: Use new lids for a proper seal; avoid reusing older lids, as they may not seal correctly.

- Basin or Sink of Water: This is optional but can help with sealing liquids.
Step-by-Step Guide to Vacuum Sealing Mason Jars
Follow these easy steps to vacuum seal your mason jars effectively.
Step 1: Prepare Your Mason Jars
Begin by washing your mason jars and lids in hot, soapy water. Rinse thoroughly and allow them to dry completely. If you’re dealing with sticky residues or want to ensure that they’re sanitized, you can also run them through a dishwasher cycle.
Step 2: Fill the Jars
Once your jars are clean and dry, it’s time to fill them with your food items. Here are some tips:
- Leave Headspace: When filling the jars, ensure you leave about an inch of headspace for dry goods and about ½ inch for liquids. This is crucial for creating an effective seal.
- Avoid Overfilling: Do not pack the jars too tightly, as this can prevent the vacuum from forming properly.
Step 3: Prepare the Foodsaver Vacuum Sealer
Next, set up your Foodsaver vacuum sealer. Follow these steps:
- Connect the hose to the jar sealer attachment.
- Plug in the Foodsaver sealer and turn it on.
- Ensure that you have properly set the sealer to the jar vacuum sealing mode. Most Foodsaver models come with this option, making it easier to switch between bag sealing and jar sealing.
Step 4: Place the Lid on the Jar
Once your jar is filled, place the clean, new lid onto the jar. Ensure that the sealing surface of the jar is clean before placing the lid to create an airtight seal.
Step 5: Initiate the Vacuum Seal Process
- Align the jar with the Foodsaver jar sealer attachment.
- Gently press the jar into the attachment. It should fit snugly and securely.
- Turn on the Foodsaver vacuum sealer, and the machine will start removing air from the jar. If you’re sealing liquids and have a basin of water, tilting the jar slightly can help create a better seal without spilling.
Step 6: Monitor the Vacuum Process
As the Foodsaver runs, you’ll hear a humming noise and see the air being pulled out. Keep an eye on the lid; once it’s pulled tight and stays in place, the jar is ready. This process usually takes a few moments. Once finished, the Foodsaver will automatically stop, and the lid should be tightly sealed onto the jar.
Step 7: Remove the Jar
Carefully lift the jar off the Foodsaver attachment. Make sure you allow the jar to sit undisturbed for a few minutes to ensure the seal sets correctly.
Step 8: Check the Seal
To ensure that your jar is sealed successfully, gently press down in the center of the lid. If it doesn’t pop back up, you’ve created a good seal. If the lid pops back up, the jar did not seal correctly, and you may need to try sealing it again or transfer the food to a new lid.
Best Practices for Vacuum Sealing Mason Jars
To get the most out of your vacuum sealing experience and ensure that your food remains safe and delicious, keep the following tips in mind:
Don’t Overpack Your Jars
Always remember that overpacking can lead to poor sealing. Giving food enough space is essential for creating a proper vacuum seal.
Use Quality Foods
The quality of the food you are sealing can impact how long it stays fresh. Always use high-quality, non-perishable items for the best results.
Label Your Jars
Consider labeling your jars with the date and contents. This helps in keeping track of what you have stored and when it was sealed, which is particularly useful for longer-term storage.
| Food Type | Recommended Jar Size | Shelf Life When Vacuum Sealed |
|---|---|---|
| Dried Beans | Quart | 1-2 years |
| Rice | Quart | 1-2 years |
| Herbs & Spices | Pint | 6 months – 2 years |
| Granola | Quart | 6 months – 1 year |

What is vacuum sealing, and why should I use it with Mason jars?
Vacuum sealing is a method of preserving food by removing air from a container, which prevents oxidation and spoilage. When using Mason jars, vacuum sealing not only extends the shelf life of your food but also helps maintain its flavor, color, and nutritional value. This method is particularly effective for dry goods, spices, and even some liquids, enabling a broader range of storage options for home cooks.
Using a vacuum sealer like FoodSaver with Mason jars provides an airtight seal that can keep your food fresh for extended periods, often several times longer than traditional storage methods. This is particularly beneficial for pantry items, pre-prepared meals, or seasonal produce, allowing you to save money and reduce food waste.
How do I prepare Mason jars for vacuum sealing?
Before vacuum sealing, ensure your Mason jars are clean and dry to prevent any contamination or spoilage. It is essential to wash them in hot, soapy water and rinse them thoroughly. You can also run them through your dishwasher to ensure they are sterile. Any leftover moisture can lead to mold growth, so be sure to let them dry completely.
When filling the jars, leave some headspace (about 1 inch) at the top. This space is necessary for proper sealing and allows for any expansion of contents. If you’re sealing liquids, consider letting them cool before sealing, as hot liquids can create steam that may interfere with the vacuum process.
Can all types of food be vacuum sealed in Mason jars?
While a variety of foods can be vacuum sealed in Mason jars, not all products are ideal for this method. Dry goods such as grains, pasta, and spices are excellent choices, as they benefit greatly from being kept airtight. However, vacuum sealing is also suitable for softer foods like fruits and vegetables, provided they are blanched first to preserve texture and flavor.
That said, certain items with a high moisture content—such as salads or delicate berries—can be tricky. These foods may become crushed during the vacuum sealing process. Additionally, avoid sealing foods that release gases, like freshly baked bread, as the vacuum seal may not hold effective due to the gases produced during fermentation or spoilage.
What equipment do I need for vacuum sealing Mason jars?
To vacuum seal Mason jars, you will need a vacuum sealer, such as the FoodSaver, specifically designed for this purpose. Additionally, ensure you have the appropriate accessory lid or attachment that fits over the lid of the jar and allows for efficient vacuum sealing. These accessories are essential, as they create the necessary suction to remove air from within the jar.
You will also need the Mason jars themselves, which come in various sizes depending on your storage needs. Always use canning jars that are designed to withstand the pressure changes from vacuum sealing to ensure safety and effectiveness. Investing in high-quality jars will ensure longer-lasting results and reduce the risk of breakage during the process.
How do I use my FoodSaver to vacuum seal Mason jars?
To vacuum seal Mason jars with your FoodSaver, start by filling the jars with your desired food, ensuring to leave enough headspace. Once filled, place the flat lid on the jar, followed by the ring to secure it. Fit the vacuum sealing attachment over the top of the jar lid and make sure it is aligned properly to create a seal.
Next, turn on your FoodSaver and select the jar sealing option. The machine will remove the air from the jar, and once it has completed the process, you’ll hear a change in sound. Remove the attachment and check the seal by pressing down the center of the lid; if it’s firm and doesn’t pop back, you’ve successfully vacuum sealed your Mason jar.
How long can I store vacuum-sealed Mason jars, and how do I know if they’re still good?
Vacuum-sealed Mason jars can greatly extend the shelf life of your food, often by several months to years, depending on the contents. Dry goods like grains and beans can last up to 1-2 years in optimal storage conditions, while vacuum-sealed fruits and vegetables may last several months, depending on their ripeness when sealed. Always store the jars in a cool, dark place to maximize longevity.
To check if your vacuum-sealed Mason jar is still good, examine the seal and the contents. The lid should remain concave and should not pop when pressed. If you notice any signs of spoilage, such as mold, off smells, or changes in color or texture, it’s best to discard the contents to ensure safety. Regularly inspect and consume your stored food to avoid waste and maintain freshness.
Can I re-seal Mason jars after they’ve been opened?
Yes, you can re-seal Mason jars after they’ve been opened, provided that the food is still fresh and safe to eat. To do this, remove any spoiled portions and ensure the remaining contents are clean and dry. If you’ve partially consumed dry goods or leftovers, it’s important to check for any signs of spoilage before attempting to re-seal.
When you’re ready to re-seal, simply follow the same process as before: transfer the contents back into a clean Mason jar if necessary, leave appropriate headspace, and fit the lid accordingly. Use your FoodSaver to vacuum seal the jar again, ensuring that you maintain the quality and freshness of the contents for extended storage.
