Best Plastic-Free Ice Cube Trays
Trays and molds for making ice.
Why plastic matters here
Water freezes and sits for days in the tray, and flexing plastic trays to release cubes stresses the material; recent attention on cold-temperature microplastic release put this cheap category on the radar. Stainless lever-action trays (the pre-plastic design) and silicone molds are the alternatives.
What to look for
- Vintage-style stainless lever trays are fully plastic-free and work well
- Silicone molds are the flexible option - platinum-cured quality matters here
- Check the freezer-to-glass workflow; steel trays release with a lever, no twisting
Our picks
The reference plastic-free ice tray: 18/8 stainless throughout - tray, grid, and lever - with no plastic, aluminum, coating, or BPA. The pre-plastic lever design cracks the whole batch loose without the twisting or flexing that stresses plastic trays. Unbreakable and buy-it-for-life; just expect cold steel and the occasional stuck cube if you overfill.
For people who want a flexible mold and accept silicone: food-grade silicone with a steel-reinforced rim so it carries flat and level, plus a fitted silicone lid to block freezer odors. Water freezes against silicone, not plastic, and cubes flex out with no twisting. Silicone-only, so strict avoiders should take the steel Onyx instead.
Considered, but not picked
Popular options that look plastic-free but aren't — and why.
Plastic twist ice trays (the standard freezer tray)
The thing these picks replace. Water freezes and sits for days against plastic, and you twist and flex the tray - stressing the material - every time you release cubes, which is exactly the mechanism recent cold-temperature microplastic-shedding concern focuses on. Cheap, but the whole reason the category is on the radar.
