So, you’ve dived headfirst into the wonderful world of sous vide cooking. You’ve seen the perfectly pink steaks, the impossibly juicy chicken breasts, and the flawlessly cooked vegetables that look like they came straight from a five-star restaurant. But maybe you’re running into a little snag: your Ziploc bags keep floating, you’re not getting that perfect, uniform cook, and you’re starting to wonder if there’s a better way. Let me tell you, there is. If you’re serious about elevating your culinary game, the first step is to buy a vacuum sealer for sous vide cooking. It’s not just a fancy gadget; it’s the key that unlocks the full potential of your sous vide machine, turning good results into consistently great ones.
Why is a Vacuum Sealer a Game-Changer for Sous Vide?
You might be asking, “Can’t I just use the water displacement method with a regular plastic bag?” You can, and it’s a decent starting point. But a vacuum sealer is like upgrading from a bicycle to a sports car. A proper vacuum seal removes virtually all the air from the bag, which is crucial for two main reasons.
First, it ensures maximum surface contact between your food and the heated water. Think of it like this: any air pocket trapped in the bag acts as an insulator, preventing heat from transferring evenly to your food. This can lead to unevenly cooked spots—a tragedy for that beautiful piece of steak you’ve been dreaming about.
Second, it prevents the dreaded “floating bag” syndrome. We’ve all been there. You carefully place your bag in the water bath, turn your back for a minute, and come back to find it bobbing on the surface like a buoy. A vacuum-sealed bag is dense and air-free, so it sinks and stays submerged, guaranteeing a perfect, edge-to-edge cook without needing to weigh it down with a spoon or a binder clip.
“The quality of your seal is just as important as the precision of your water temperature. A perfect vacuum is the foundation of a perfect sous vide cook.” – Chef Julian Carter, author of “The Modern Kitchen.”
The Two Main Players: Chamber vs. Edge Sealers
When you start looking to buy a vacuum sealer for sous vide cooking, you’ll quickly discover there are two main types on the market. Understanding the difference is key to choosing the right one for your kitchen.
Edge (Suction) Sealers: The Home Cook’s Hero
This is the type most people are familiar with. They’re compact, sit on your countertop, and are relatively affordable. They work by placing the open end of a specially textured bag into the machine, which then sucks the air out before heat-sealing the edge.
- Pros:
- Affordable: Great for beginners and home cooks on a budget.
- Small Footprint: Easy to store in a cabinet or on the counter.
- Versatile: Excellent for sealing solid foods and prepping for the freezer.
- Cons:
- Struggles with Liquids: They tend to suck liquids up into the machine, which can result in a failed seal and a big mess.
- Requires Special Bags: You need to use embossed or textured bags, which can be more expensive.
Chamber Sealers: The Professional’s Powerhouse
Chamber vacuum sealers are the big leagues. You place the entire bag inside a chamber, close the lid, and the machine removes the air from the entire chamber. This equalizes the pressure inside and outside the bag, so liquids stay put. Once the air is removed, a sealing bar inside clamps down and seals the bag.
- Pros:
- Seals Liquids Flawlessly: Perfect for soups, stews, marinades, and infusions.
- Stronger, More Reliable Seal: Generally provides a superior, commercial-grade vacuum.
- Cheaper Bags: Uses smooth, simple vacuum pouches, which cost significantly less in the long run.
- Cons:
- Expensive: A significant investment compared to edge sealers.
- Large and Heavy: Takes up a lot of counter space and is not easily portable.
For most home sous vide enthusiasts, a high-quality edge sealer is more than enough to get the job done beautifully.
How to Use a Vacuum Sealer for Sous Vide: A Step-by-Step Guide
Got your new machine? Fantastic! Let’s walk through the process. It’s incredibly simple once you get the hang of it.
- Prep Your Food: Pat your protein dry with a paper towel. Add any dry seasonings, herbs, or a small amount of fat like butter or oil.
- Choose the Right Bag Size: Select a bag that gives you at least a few inches of extra space at the top. You don’t want to overfill it.
- Place Food in the Bag: Gently slide your food into the bag, arranging it in a single, flat layer. This is crucial for even cooking.
- Position the Bag in the Sealer: Open the sealer and place the open end of the bag across the seal bar, making sure it’s lying flat and wrinkle-free within the vacuum channel.
- Seal it Up: Close the lid and lock it. Press the “Vacuum & Seal” button. The machine will whir to life, sucking out the air until the bag is shrink-wrapped around your food, and then it will automatically apply heat to create a strong seal.
- Inspect the Seal: Once the cycle is complete, open the lid and check the seal. It should be clear, complete, and have no gaps or wrinkles. If you’re sealing something for a long cook, it never hurts to add a second seal just above the first one for extra security.
Pro Tips for the Perfect Sous Vide Seal Every Time
After sealing thousands of bags, I’ve learned a few tricks that make a world of difference.
- Cuff the Bag: Before adding your food, fold the top two inches of the bag outward to create a cuff. This prevents any moisture or food particles from getting on the sealing area, which can cause a weak seal.
- Freeze Your Liquids: Want to seal a marinade with your steak using an edge sealer? No problem. Pour the marinade into an ice cube tray and freeze it. Add the frozen marinade cubes to the bag with your protein. They won’t get sucked into the machine!
- Don’t Overfill: This is the most common mistake. Too much food in a bag makes it difficult for the machine to get a flat, clean surface to seal.
- Double Seal for Long Cooks: If you’re doing a 24-hour or 48-hour cook (like for short ribs), always use a double seal. It’s a tiny bit of extra effort that provides huge peace of mind.

To Seal or Not to Seal: What Works Best for Sous Vide?
A vacuum sealer is incredibly versatile, but not everything is meant to be sealed. Here’s a quick rundown.
Foods That Love to be Vacuum Sealed for Sous Vide
- Proteins: Steak, pork chops, chicken breasts, fish fillets. Sealing with herbs and aromatics infuses incredible flavor.
- Tough Cuts: Brisket, chuck roast, and pork shoulder become incredibly tender during long sous vide cooks.
- Vegetables: Carrots, asparagus, potatoes, and corn on the cob cook perfectly in their own juices, concentrating their natural sweetness.
- Eggs: For custards, crème brûlée, or perfect poached-style eggs.
Foods That Need a Little Extra Care (or Shouldn’t Be Sealed)
- Cruciferous Vegetables: Things like broccoli, cauliflower, and Brussels sprouts release gases as they cook. It’s best to blanch them quickly before sealing to prevent the bag from puffing up.
- Soft Cheeses and Mushrooms: These delicate items can be crushed by a powerful vacuum. Use the “pulse” function if your machine has one, or simply stop the vacuum process manually before it gets too tight.
- Raw Onions and Garlic: Sealing these raw can sometimes result in an unpleasant, sharp flavor. It’s often better to cook them lightly before sealing.
What Should I Look for When I Buy a Vacuum Sealer for Sous Vide Cooking?
Ready to make the purchase? Keep these key features in mind to ensure you get a machine that will serve you well for years of delicious sous vide meals.
- Sealing Power: Look for a machine with a strong motor and a reliable vacuum pump. This ensures you get as much air out as possible.
- Seal Bar Width: A wider seal bar creates a stronger, more secure seal. This is especially important for wet foods or long cooking times.
- Moist and Dry Food Settings: A dedicated “moist” setting is a lifesaver. It uses a gentler vacuum and a longer sealing time to help prevent liquids from being drawn into the machine.
- Built-in Bag Storage and Cutter: These are fantastic quality-of-life features. They keep your rolls tidy and allow you to cut custom-sized bags with a perfect straight edge every time.
- Accessory Port: This allows you to use your sealer with reusable containers and jar sealers, expanding its use far beyond just sous vide cooking.
- Ease of Cleaning: A removable drip tray will make cleanup a breeze, especially on the rare occasion that some liquid does get pulled from the bag.
Frequently Asked Questions
What is the best vacuum sealer for a beginner?
For most beginners, a reliable edge sealer from a reputable brand like Nesco, FoodSaver, or Anova is an excellent choice. Look for one with both moist and dry settings to give you the most flexibility as you start your sous vide journey.
Can I reuse sous vide bags that have been vacuum sealed?
Technically, yes, if you wash them thoroughly and they haven’t held raw meat. However, you have to cut off the old seal, making the bag shorter each time. For food safety and convenience, especially after cooking raw proteins, it’s generally recommended to use a new bag each time.
Do I really need a vacuum sealer, or are Ziploc bags good enough for sous vide?
Ziploc bags with the water displacement method work, but they are more prone to leaking and floating. A vacuum sealer provides a far more reliable, consistent, and foolproof result, which is why it’s the preferred method for anyone serious about sous vide.
Can you vacuum seal liquids like soup in an edge sealer?
It’s tricky but possible with a workaround. The best method is to freeze the liquid in a container or ice cube tray first, then seal the frozen block. This prevents the liquid from being sucked into the vacuum channel.
How much should I spend when I buy a vacuum sealer for sous vide cooking?
A quality edge sealer for home use typically ranges from $80 to $200. While cheaper models exist, investing in a slightly better machine often pays off in terms of sealing power, reliability, and useful features that you’ll appreciate in the long run.
Your Culinary Journey Awaits
