The best onion keeper depends on what you store: a sealed, onion-shaped saver keeps a cut half fresh in the fridge without stinking it up, while a dark, vented bin keeps whole onions dry in the pantry. Many kitchens use one of each.

We compared six onion keepers on Amazon US by fit, seal, odor control and cleaning.
