How We Decided

In determining the best onion storage and saver to buy, we explored moisture/air-sealing ability shape/size, construction, safety, and ease of use.

Moisture & air sealing ability should be at the top of the list. Our recommend onion savers have airtight seals. Some are made using silicone with small metal disks to help prevent odors from leaking. Others use simple screw-on lids and others come in a top twist design to adjust the tightness.

Shape/size is an important consideration. Our picks can accommodate at least a half onion, with larger ones like the #7 pick Tupperware Onion Storage and Saver good for a full onion. Others, like our #6 pick OXO Good Grips Onion Storage and Saver, have flexible silicone lids that adhere to your chopped vegetable or onions contours, allowing a little extra space.

Safety is key. All of our onion storage and savers are BPA free. BPA is a common additive found in plastics that are known to cause health defects. A BPA-free designation ensures its completely safe to store foods in. Kudos for onion savers that are also dishwasher safe, which helps cut on food prep time.

Lastly, we focused on onion storage and savers that are easy to use. It should require no more than cutting the onion, placing it flat on a flat base, and closing a hinge shut or tightening using a top twist lid. This process should take no more than two seconds.
