Can You Use FoodSaver Bags for Sous Vide Cooking? The Ultimate Guide

Sous vide cooking has revolutionized gourmet kitchens and restaurants over the last decade with its ability to cook food to tender, succulent perfection through precise temperature control. This innovative technique involves sealing food in plastic bags, then bathing the bags in a hot water tank held at a specific target temperature.

Vacuum sealing food is a critical part of sous vide. And when it comes to selecting the right bags, FoodSaver bags are one of the most popular and trusted choices. Their durable, BPA-free plastic and reliable seals help lock in moisture and flavor when cooking sous vide style.

In this detailed guide, we’ll explore everything you need to know as a beginner or pro about harnessing FoodSaver bags’ capabilities for sous vide. You’ll learn professional chef tips for selecting, sealing, and troubleshooting bags so you can achieve restaurant-quality results. Let’s dive in!

A Quick History of Sous Vide Cooking

While trendy now, sous vide actually originated back in the 1960s, when French and American engineers pioneered using precise temperature-controlled water baths to cook food sealed in cryovac plastic bags. The method helped revolutionize food manufacturing.

In the 1970s, pioneering French chefs like Georges Pralus adopted sous vide for fine dining after realizing it enabled perfectly cooked foie gras and poultry. Over the next decades, immersion circulators and vacuum sealers improved, allowing sous vide to take restaurant kitchens by storm.

Now consumer-friendly machines from Anova, Joule, and FoodSaver make sous vide easily achievable at home. And FoodSaver’s specially designed bags provide the ideal vessel for cooking.

Why FoodSaver Bags Are Great For Sous Vide

FoodSaver bags are purpose-built for sous vide cooking and vacuum food preservation in general. Here’s a breakdown of what makes them a top choice:

Airtight Seal

FoodSaver’s powerful suction removes nearly all air from around food before heat-sealing the bag shut. Tests show their seals withstand up to 60kPa of pressure without leaking or popping. This airtight barrier locks in moisture and flavors.

BPA-Free and Food Safe

The plastics used in FoodSaver bags are BPA-free and approved food-grade materials resistant to warping or deterioration from hot water over time. You don’t have to worry about chemicals leaching.

Superior Moisture And Flavor Retention

Eliminating oxygen allows juicier, more intensely flavored results. In fact, vacuum compression can increase marinade penetration up to 10 times faster according to research.

Easy To Use

FoodSavers use a simple thermoplastic material that reliably fuses shut with heat sealing. No annoying zippers or clips to futz with and potentially leak.

Durable Construction

Made from multi-ply polymers, FoodSaver bags are puncture and tear resistant. The premium bags have 30% thicker plastic for extra protection during extended sous vide cooking.

Allows Frozen Food Storage

You can freeze sous vide meals inside the same FoodSaver bags used for cooking. The airtight seals and durable material hold up for long frozen storage.

Selecting The Right Bags For Your Needs

FoodSaver offers sous vide and vacuum seal bags in a range of material thicknesses, sizes, and features. Here are some tips for picking the optimal bags:

• Cook time – For sous vide cooking under 24 hours, standard bags work well. Go for thicker premium bags for 24+ hour cooks.

• Bag size – Aim for a tight fit with 2-3 inches of extra space at top to allow for sealing. Get wide-mouth bags for larger cuts of meat.

• Single meal or batches – Quart and gallon bags are good for family-sized portions. Fill bags 2/3 full for circulation.

• Reuse – Reusing FoodSaver bags is not recommended for sous vide due to material weakening. Stick to new bags per cook.

• Special features – Some FoodSaver bags have special channels or mesh pouches for marinades or seasonings.

Mastering The Art Of Sealing Sous Vide Bags

Achieving a strong, airtight seal is critical when FoodSaving bags for sous vide. Follow these pro steps:

1. Add Food

Place your seasoned food flat across the bottom of the bag. Positioning it evenly helps achieve a good vacuuming.

2. Remove Air

Run the open end of the bag through the FoodSaver vacuuming channel. This will suck out all the air and begin sealing the bag closed.

3. Seal The Bag

The FoodSaver uses heated thermoplastic rollers to fuse the two sides of the bag together. Take care not to twist the bag as it feeds through.

4. Test The Seal

Examine the seal for any gaps where air could sneak in. Press along the seal to check for weaknesses. Reseal if any faults are found.

5. Remove Air Pockets

Gently massage the bag once sealed to flatten out any remaining air bubbles along the food. This helps prevent floating.

6. Submerge The Bag

Clip the corner of the sealed bag to the edge of your sous vide water bath container. The bag must stay fully submerged.

Pro Sous Vide Sealing Tips

• Lay bags flat in the sealer rather than twisting – twisting can wrinkle the seal.

• Seal twice for an extra airtight seal – double sealing is good insurance for very long cooks like 48+ hours.

• Wet the seal edges – Moistening the lip of the bag just before sealing helps the plastic bond tighter.

• Don’t overfill – Leave 3-5 inches of empty space at the top so the bag can fully vacuum.

Maintaining Proper Food Safety

While sous vide cooking is generally safe when done correctly, special care should be taken with FoodSaver bags to avoid bacterial risks:

• Start with quality fresh food – Bacteria multiplies much faster in the anaerobic environment inside bags.

• Defrost fully before sealing – Ice crystals can poke microscopic holes that let in air and microbes.

• Pre-sear meat if cooking longer than 2-4 hours – Searing kills surface bacteria that can otherwise proliferate during extended cooks.

• Chill after cooking – Don’t leave warm bags at room temp; refrigerate sealed cooks immediately, within 1 hour.

• Avoid reusing bags – Even slight, invisible seam damage can compromise vacuum sealing and allow bacteria in.

Handy Hacks For Storing and Reheating

One beauty of sous vide is being able to prepare meals in advance. Here are some tips for storing and reheating sealed foods:

• Fridge storage – Sealed leftovers keep fresh for 4-5 days refrigerated.

• Freezer storage – Sous vide food frozen in FoodSaver bags keeps for 6 months+. Thaw for 12-24 hours before reheating.

• Reheating – Still sealed, run bags under hot tap water or drop back into a 115°F water bath to gently reheat.

• Serving – Snip open the corner of the bag with scissors to drain juices before plating.

Troubleshooting FoodSaver Bag Issues

Here’s how to tackle common FoodSaver bag challenges with sous vide:

Leaking – Double check seal integrity. Look for wrinkles and re-seal those spots. Make sure the bags stay fully submerged.

Floating – Try pressing out all excess air after sealing. Some foods like eggs naturally float more than denser items.

Melting – Ensure water bath temps don’t exceed the bag’s heat rating. Use very thick premium bags for cooks exceeding 24 hours.

Food drying out – A broken seal exposing food to air can cause this. Examine the vacuum seal closely for any openings.

Poor sealing – Inspect that the bag edges aligned well and fused together without gaps. Clean the bags thoroughly as oils can prevent sealing.

Creative Uses Beyond Sous Vide

While designed for sous vide, FoodSaver bags can streamline general meal prep and storage in many helpful ways:

• Speed up marinating – Vacuum compression forces marinade into meat fast.

• Portion and freeze stocks and sauces – Save freezer space with flattened bags.

• Prep bulk dry ingredients – Seal measured amounts of grains or seasoning mixes for fast weeknight meals.

• Make giant ice cubes – Fill bags 2/3rds with water and seal flat for chilling cocktails.

• Brine chicken breasts – Submerge seasoned bags of chicken in the fridge for juicy infused meat.

Key Takeaways for Sous Vide Success

The ability to precisely control temperatures while locking in moisture and flavor makes FoodSaver bags a perfect match for sous vide cooking. For flawless results, opt for thick premium bags rated for higher heats, and be meticulous when sealing to remove all air. Follow proper food safety guidelines, avoid reusing bags, and handle bags gently to prevent seam damage.
