How to Use your Sous Vide Sustainably Part 1: Eco-Friendly Stasher Bag Edition

Late last year, we announced the launch of our social impact program. That means as a company, we are taking a look at who we are and what we stand for. This also means being honest about the areas we know we need to improve.

It should come as no surprise that one of the largest drawbacks of cooking sous vide is the creation of plastic waste. Don’t get us wrong, we love sous vide here at Anova – we eat, breathe and sleep it. But we don’t like creating waste any more than you do. It’s a tough, industry wide problem with no perfect solution (yet). But if you know Anova, then you know that we love a challenge. That’s why we are working hard to bring a recyclable, biodegradable bag to market in 2020. We know that doing so will be a big win for everyone.

The good news is that in the meantime, there are plenty of awesome existing alternatives to cooking in plastic and some simple tips and tricks you can follow to reduce the amount of plastic you use. To help you get started, we are launching a four blog series around how to use your sous vide sustainably. The blog series will cover:

  1. Cooking with the Stasher Reusable Silicone Bag for Anova
  2. Cooking in high-quality plastic zipper-lock bags
  3. Cooking in glass jars
  4. Cooking with the Anova Precision® Vacuum Sealer + bags

There are options for everyone. So for all the eco-conscious #anovafoodnerds out there… this series is for you!

Cooking with Stasher – Eco-friendliest option

You love sous vide, but you also love the environment. You use reusable shopping bags, have a stainless water bottle, recycle, compost, and always say no to plastic straws. You don’t want to create excess waste every time you cook. If this sounds like you, then let us introduce you to your new bestie – the Stasher Reusable Silicone Bag for Anova.

Stasher + Food Storage


Stasher is a patented, award-winning design that is eco-friendly, environmentally safe, and long-lasting. It’s a smart alternative to plastic and has prevented millions of single-use plastics from piling up in landfills and polluting oceans. The bag is made of pure platinum silicone that is made from natural resources — primarily sand. It’s 100% plastic and BPA free with no fillers. Stasher Bags are food safe, have an airtight seal, can be submerged in boiling water, and are dishwasher safe (top rack recommended).

Stocking your Stasher collection may be a bit more of an upfront investment, but once you have the amount you need, you won’t need to keep buying expensive plastic bags – which actually saves you money in the long run. They are also a great way to store your leftover food. Just toss excess food in the bag, store it into the fridge, and reheat with Anova when ready for the same incredible meal.

And in case you didn’t love it already – Stasher is a certified B Corporation and a 1% for the Planet business partner. The company supports non-profits in environment conservancy and female empowerment through philanthropy, volunteering, and community activism. They’ve even developed a repurpose program that turns your old bags into playground pebble. That’s a win-win-win.


For those of you who are thinking “this sounds too good to be true” – Stasher bags aren’t perfect. The bags’ thicker walls and stiff closure mean that forcing the air out is a bit tedious. For the perfectionists out there – we recommend using a (metal) straw to get the remainder of the air out of the bag or watching this video for tips on how to roll the air out. The bags are also more buoyant, so you may have to weigh your cook down with a spoon or fork to keep the bag from floating to the top.

There are also size limitations to what you can cook. The largest bag is a half gallon, so you won’t be able to sous vide a whole turkey using Stasher – unless you break it down into smaller pieces and use multiple bags (unleash your inner MacGyver!).

Even though there are a few issues, overall, we believe Stasher is a win for your wallet and a win for the environment. Learn more about Stasher and purchase your very own reusable silicone bag here.
