Buying guide
The best reusable food storage, from leftovers to lunch
Elle Marchetti · Published October 15, 2026
The quick answer
For most kitchens, the Stasher Stand-Up Mid silicone bag is the most useful single piece of reusable food storage: it seals genuinely airtight, goes from freezer to microwave to dishwasher, and replaces the roll of zip bags entirely. For stacked leftovers, glass with a locking lid is the better buy.
Glass vs silicone vs stainless
- Glass stains never, microwaves best, and breaks when dropped. Best for fridge leftovers.
- Silicone bags are unbreakable and freezer-friendly, and replace disposables one-for-one. Best all-rounder.
- Stainless is light and indestructible but cannot be microwaved and you cannot see inside. Best for lunches out.
What fails first
Lids, always. Silicone seals and locking tabs outlive snap-on plastic lids by years. Budget for the container whose replacement lids you can actually buy.
Our recommended picks
Frequently asked
- Do silicone food bags stain or hold smells?
- Strongly coloured foods like tomato sauce can tint silicone, and garlic lingers. A baking-soda paste overnight clears both. Glass is the answer if this bothers you.
- Is it safe to microwave silicone storage bags?
- Food-grade platinum silicone is rated for microwave, oven and sous-vide use by its manufacturers. Keep the seal partly open so steam escapes.
