How To Use The Foodsaver Vacuum Seal

If you’ve just bought a FoodSaver vacuum sealer, you’re probably excited to start preserving your food. Learning how to use the FoodSaver vacuum seal system is the key to getting the most from your machine and keeping your food fresh for much longer.

This guide will walk you through everything, from setup to advanced tips. We’ll cover the basics, common mistakes to avoid, and clever uses you might not have thought of. By the end, you’ll be sealing like a pro.

This section covers the core process. While models vary, the fundamental steps are the same for most FoodSaver vacuum sealers. Always check your manual for specific instructions for your model.

What You’ll Need to Get Started

Before you begin, gather your supplies. Having everything ready makes the process smooth and efficient.

Your FoodSaver vacuum sealer machine.
FoodSaver vacuum seal bags or rolls (make sure they’re the right type for your model).
The sealing accessory you need (usually the included vacuum sealer hose).
Fresh food you want to preserve.
A clean cloth or paper towel (for wiping bag edges).

Step-by-Step Sealing Instructions

Follow these numbered steps for best results. It’s simpler than it seems once you get the hang of it.

Prepare Your Food: For best results, food should be cool or frozen. Pat meats and veggies dry with a paper towel to remove excess moisture. Moisture can interfere with the vacuum and sealing process.
Cut and Position the Bag: If using a roll, cut a bag length that gives you at least 3 inches of extra space above the food. Place your food inside, keeping the top opening clean and dry.
Start the Vacuum Seal: Place the open end of the bag into the vacuum channel on your machine. Make sure the bag’s end is flat and fully inside the sealing area. Close the lid until it locks.
Select the Mode: Choose the appropriate setting. Use “Dry” for solid foods like meats, nuts, and dry goods. Use “Moist” for foods with more liquid, like soups, sauces, or marinated items. Some models do this automatically.
Activate the Machine: Press the vacuum seal button. You’ll hear the machine remove the air and then heat the seal bar to close the bag. The process usually stops automatically.
Check the Seal: Once the light goes off, open the lid. Gently tug on the sealed end to ensure it’s completely closed and airtight. If the seal feels weak, you can run it through the “Seal Only” cycle again.

Using the Canister and Hose Attachment

Your FoodSaver isn’t just for bags. The hose attachment opens up a world of possibilities with special containers.

Connect the hose to your FoodSaver machine and to the valve on a FoodSaver canister or jar sealer lid.
Press the accessory button (often marked with a hose icon) or select the correct mode.
The machine will remove the air from the container and stop. This is perfect for storing leftovers, dry goods, or marinating meat quickly right in the container.

Essential Tips for Perfect Sealing Every Time

A few simple tricks can make a huge difference in the quality of your seal and the longevity of your stored food.

Avoiding Common Mistakes

Even experienced users can make these errors. Being aware of them will save you bags and frustration.

Overfilling the Bag: Leave enough space—about 3 inches—between the food and the top of the bag. This gives the machine room to grab the bag and create a proper seal.
Sealing Wet or Dirty Bag Edges: Any moisture, crumbs, or grease on the inside of the bag’s opening can prevent a strong seal. Always wipe the inside clean with a dry cloth before sealing.
Using the Wrong Setting: Trying to seal liquid-heavy food on a “Dry” setting can cause liquid to be sucked into the machine, which can damage it. When in doubt, use the “Moist” setting or freeze liquids first.
Ignoring the Gasket: The rubber seal around the vacuum channel needs to be clean and intact. Check it regularly and wipe it clean to maintain a good suction.

Pre-Freezing for Better Results

For messy or liquid items, pre-freezing is your best friend. This technique, often called “flash freezing,” is incredibly useful.

Place items like soup, stew, or juicy berries on a parchment-lined baking sheet.
Freeze them until they are solid (usually 2-4 hours).
Transfer the frozen blocks to your vacuum bag and seal as normal. This prevents mess and ensures a perfect vacuum around each piece.

Creative Uses Beyond Leftovers

Your FoodSaver is a versatile tool. Here are some smart ways to use it that go beyond just storing meat in the freezer.

For Meal Prepping and Portion Control

Vacuum sealing is a game-changer for planning meals. It saves time and reduces waste.

Cook a large batch of chicken breasts, rice, or vegetables. Portion them into single-serving bags, vacuum seal, and refrigerate or freeze. Reheat quickly in boiling water.
Seal individual portions of snacks like nuts, crackers, or cheese sticks to grab and go.

For Sous Vide Cooking

If you enjoy sous vide, your FoodSaver is essential. Vacuum sealing locks in flavor and ensures even water bath cooking.

Season your protein, place it in a bag with herbs or butter, and vacuum seal. The airtight bag guarantees perfect heat transfer during the long, low-temperature cook.

For Protecting Valuables

The vacuum seal isn’t just for the kitchen. It creates a waterproof, airtight barrier that’s great for protection.

Seal important documents, photos, or first-aid supplies before camping or boating trips.
Store seasonal clothing or blankets to protect them from moths and moisture.
Create airtight containers for craft supplies like glitter or messy dyes using the hose attachment.

Cleaning and Maintaining Your Machine

Proper care ensures your FoodSaver lasts for years. Neglecting maintenance is a common reason for early failures.

Routine Cleaning Steps

You should clean your machine after every few uses, or immediately if any liquid gets inside.

Unplug the machine and let it cool completely.
Open the lid and remove any visible debris from the vacuum channel and sealing area.
Wipe the entire sealing area, the rubber gasket, and the inside of the lid with a damp cloth. Dry thoroughly.
Empty the drip tray if your model has one. Some newer models have a removable tray that can be washed.

Dealing with Clogs and Weak Suction

If your machine seems weak or won’t seal, a clog is often the culprit. Food particles or moisture can block the vacuum pathway.

Consult your manual for specific cleaning instructions for the vacuum port. Often, you can use a pipe cleaner or cotton swab to gently clear the opening.
Ensure the bag is not blocking the vacuum channel when you close the lid; it should lay flat.
If problems persist, the charcoal filter (on some models) may need replacement. Check your manual for guidance.

Frequently Asked Questions (FAQ)

Here are answers to some of the most common questions about using a FoodSaver sealer.

Can I reuse FoodSaver bags?

It is not generally recommended. The sealing process melts the plastic layers together. Cutting below the seal and trying to reseal can compromise the bag’s integrity and may not create an airtight closure. For reusable options, focus on the hard plastic canisters designed for multiple uses.

What can’t I vacuum seal?

Avoid sealing raw mushrooms (they release gases), soft cheeses that can be crushed (like brie), and fresh garlic or onions (their gases can cause botulism risk in anaerobic environments unless frozen). Also, never vacuum seal anything you intend to fry, as the bag can collapse in hot oil.

How long does vacuum-sealed food last?

In the freezer, vacuum-sealed meat can last 2-3 years compared to 6-8 months with standard wrapping. In the refrigerator, cooked meals or deli meats can last 1-2 weeks instead of just a few days. Always label your bags with the date and contents.

Why did my bag fail to seal properly?

The most common reasons are: 1) Moisture or crumbs on the sealing area, 2) A wrinkle in the bag material at the seal line, 3) An overfilled bag, or 4) A worn-out sealing strip on an older machine. Double-check your technique and ensure the bag is smooth and clean before trying again.

Is it safe to cook food in the vacuum bags?

Only if the bag is specifically rated for cooking, like those intended for sous vide. Standard vacuum bags are made for storage and freezing and may leach chemicals if heated directly. Always check the bag’s packaging for cooking instructions and temperature limits.

My machine is beeping, what does that mean?

Beeping usually indicates an error. Common causes include an open lid, a bag that’s too short or not inserted correctly, or a clog that’s preventing proper vacuum. Turn the machine off, unplug it, check for blockages, and ensure the bag is placed correctly according to the manual.

Mastering your FoodSaver takes a little practice, but the benefits are immense. You’ll reduce food waste, save money by buying in bulk, and make meal planning simpler. Start with dry, easy items like crackers or frozen vegetables to build your confidence. Before long, you’ll find new and inventive ways to use your sealer in your daily routine. Remember to keep the sealing area clean, don’t rush the process, and always label your bags clearly.
