Review: Favorite of all Times - This onion keeper really is my favorite of all time! I am on my third one and I hope they never quit selling them. I can’t tell you if it is dishwasher safe, I would not take the chance of ruining it. This onion keeper has a nice, tight fitting lid with a stainless steel plate built into it that does not allow any smells to escape. It holds a medium sized onion either whole, sliced or diced; I usually keep diced onions in mine for sandwiches and salads. It keeps them fresh a lot longer than simply wrapping leftovers in a piece of aluminum foil. They are durable, but like I mentioned above, I only hand wash mine. They are a really good value, handy for ready-to-use onions and I have gifted many of these. I will continue to buy as long as they are available! Fingers crossed.
Review: Onion? No Odor. - Great onion container! The metal disc in the top really keeps the onion odor away. Can store a large onion & keep it fresher than plastic wrap or bag. This was a replacement for my old one that was 6+ years old. Is dishwasher safe.

### ⭐⭐⭐⭐⭐ Onion? No Odor.

Great onion container! The metal disc in the top really keeps the onion odor away. Can store a large onion & keep it fresher than plastic wrap or bag. This was a replacement for my old one that was 6+ years old. Is dishwasher safe.

### ⭐⭐⭐⭐⭐ Best Onion Keeper
*by K***Y on November 28, 2025*

This is one kitchen item that I will always have, it truly locks in the odor. But I do sanitize both top and bowl by spraying hydrogen peroxide before washing. Well worth the extra step and avoid the smell of raw onions. I'm now on my 3rd keeper. Each one lasted at least 5 years, provided you don't accidently drop it and it develops a crack. It is the best Onion Keeper.
