So let’s get cooking! Here are all the ways you can use our Stasher bags:


Make meal prep easy and store portions in the fridge or freezer for future use or a quick and easy home-cooked meal. Stasher protects food from freezer burn and helps seal in freshness.


When you’re finished cooking, your Stasher bag can go straight into the dishwasher, making cleanup a breeze!


Steam fresh or frozen veggies by placing them in your Stasher bag with olive oil and any herbs and spices. Then place the bag in boiling water for about 10 minutes. Open carefully and enjoy! Using this method, you won’t lose any of the nutrients in the water and you won’t have to worry about your veggies tasting like plastic.


To reheat or steam fresh or frozen food in the microwave, simply leave your stasher bag open and handle with caution.


Sous vide is a method of cooking in which food is sealed in airtight bags then placed in water for longer than normal cooking times (usually 1 to 6 hours) at a regulated temperature much lower than normally used for cooking. The intent is to cook the item evenly, ensuring that the inside is properly cooked without overcooking the outside, and retain moisture. Traditionally, food is cooked in plastic when using the sous vide method. But when plastic is heated it accelerates the release of harmful chemicals that leech into your food. Instead, use the plastic-free Stasher bags that are made from food-safe, 100% pure platinum silicone.



Q: So what exactly is silicone?
A: Silicone is made from sand (silica) and oxygen, natural resources that give stasher bags the purity of glass and functionality of plastic. Better yet, stasher products are made of 100% pure platinum grade silicone — a standard even higher than food grade silicone, passing all U.S. safety requirements and even tougher European standards.

Q: And what makes silicone better than plastic?
A: Silicone is safer, more flexible, and more sustainable than plastic. Plastic is a petroleum-based product that introduces toxic chemicals to our food and environmental concerns to our planet.

Q: Stasher bags are BPA free?
A: Yes. There are no fillers or petroleum-based products in stasher — no BPA, BPS, lead, latex, or phthalates.

Q: Can you cook with stasher?
A: Stasher bags are safe for use in the microwave, sous vide machine, standard oven, or a pot of boiling water — up to 400F.

Q: And if I want to store soups in the freezer?
A: Stasher is freezer safe, but use caution carrying and storing liquids. It should be okay to fill the stasher bag with liquid and place it upright in the freezer.

Q: Dishwasher safe?
A: Totally. Use the upper rack for best results.

Q: I’m hearing a lot of about cooking sous vide with stasher. Why?
A: Sous vide is a popular slow cooking technique that seals in flavor and nutrients. And stasher was born to sous vide.

Place your ingredients in stasher, then seal the bag, leaving a 2-inch opening anywhere on the seal. Then slowly submerge your bag in water, the pressure of the water on the outside of the bag will push out any excess air and create a vacuum tight seal around your food. Once you have the bag almost fully submerged, pinch the seal completely closed to avoid any air coming in.


Q: Does silicone stain?  
A: Because we don’t use any toxic sealants for stasher, the silicone can stain. The best way to avoid this is to choose a bag color that corresponds with your food, e.g. a citrus stasher for red spaghetti sauce. You can also reduce staining by immediately cleaning after use.

  1. Make a baking soda paste with vinegar or water
  2. Apply to discolored container
  3. Let sit for at least 20-30 mins
  4. Rinse and wash the bag like normal

Q: Do the bags absorb smells?
A: Stasher silicone is nonporous, inhibiting bacterial growth and odors. Certain smelly foods may leave a slight odor in the bag, but that can be remedied with a thorough washing or baking soda soaking. A fresh slice of lemon left in overnight can help too.

Q: How do you clean the corners of the bag?
A: We suggest filling the bag a 1/4th of the way with warm water and soap and giving it a nice shake. A little brush helps too.
