How We Tested
Best Overall: Good Grips Cut & Keep Onion Saver
Although this is specifically designed for onions, we found OXO’s Good Grips Cut & Keep Saver worked for avocados, too. The food saver line from OXO has options for onions, lemons, limes and tomatoes, but we found the onion-sized product fit avocados best. After laying the avocado face down on the hard plastic bottom, the silicon covering on top hugs the whole avocado and snaps shut on the outer circle, ensuring an air-tight seal no matter how the avocado is cut. We found it works best to remove the pit from the avocado, so it can lay flatly on the saver. At the end of the week, the sides and bottom of the avocado were less brown than the others we tested, but slightly mushy, nonetheless. The top and pit area remained almost as green as day one. Try to use your avocado by the fifth day of storage to hit the sweet spot for this avocado keeper before the brownness really sets in.
Best for Pits: Evriholder Avo Saver
At first we were hesitant about this product because it seemed like you had to cut the avocado perfectly in half to keep both ends air-tight against the holder (and, unless you’re a robot, that’s kind of impossible to do). But nevertheless, this avocado was one of the freshest after a few days, despite our slightly uneven cutting! Having the pit still inserted helps the whole avocado to stay fresher for a longer amount of time. The sides browned quicker than the top and bottom areas did. The adjustable strap allows the avocado to be tucked in snugly no matter how big or small it may be.
Most User-Friendly: Prepworks by Progressive Avocado Keeper
All you have to do with this gadget is place your cut avocado face down after taking out the pit and snap on the lid! No matter what shape or size your avocado is, it’s sure to fit neatly in this air-tight case. It’s easily stackable, too, so you don’t have to worry about your avocado getting smushed. The total surface area was browner than our top two products, but removing the top browner layer with a knife will give you use of the rest of the avocado.
