Glass, metal, ceramic, old fashioned plastic. The problem is generally packaging materials not things like Tupperware or glassware.

Yeah that's what I use as well, but I only use plastic for storing cold thing like salad.

Glass containers are fantastic and usually cheap enough. Whether it's spice jars or leftover food containers, it all works great. Make sure the lids are also either glass, wood, or stainless steel.

The one "downside" is you do need adequate cushion if you're taking it on the go say for lunch or to a dinner gathering, but even a towel wrapped around suffice.

If you want recommendations, the Ikea 365+ glass containers are fantastic and very cheap. Again avoiding the "plastic lid" variant they have for extra measure.

I got glass containers with plastic lids because I figure the lid rarely contacts the food, and I always take it off to microwave... although now that I'm thinking about it, I usually put that plastic splatter guard thing over the container in the microwave which probably isn't much better.

Used to do the same. Thankfully there are glass splatter guards out there, some of them with plastic handles on the outside. More expensive than you would hope though, I suppose because it's such a niche use, but it's not as if you're going to be buying many glass microwave covers in one's lifetime!

I usually put a saucer or plate over the top!

I put a paper towel on food in the microwave to stop splatter. As a bonus, I've found a moist paper towel helps when microwaving leftovers that got dehydrated in the fridge.

I beg to differ. The IKEA 365+ non-glass containers are fantastic. The glass ones don’t stack properly and tend to have little glass shards break off when unstacking them. I can imagine a v2 being better.

I don't think the glass containers stack well if you stack them separately from their lids, but I have the bamboo and glass ones and they stack flawlessly closed. I have high shelf space though so I know that's not an option for everyone.

Plastic lid is normally fine, plastics leech at high temperatures, you arent normally heating food with the lid on. .Even eith a fully steel container you need a bit of soft material lile silicone to ensure waterproof seal

Good point. I also generally dislike plastic lids because the "snap lock" mechanic always tend to go wonky. The bamboo lids with silicone edges tend to be the least hassle.

I have a set of glass containers with tight sealing lids. A little heaver and doesn't pack together as small as plastic does when not in use, but it's a lot easier to clean

I frequently order too much in restaurants on purpose to have leftovers. I'm gonna start bringing reusable glass containers.

Not OP, but: glass with metal lids and silicon seals, or glass... with hard plastic lids. :|

I also keep my rices and legumes in bamboo boxes.

“ metal lids and silicon seals”

Are you in the US? I don’t think I’ve seen these around.

Ah, mason jars. I was mistaken and thought the comment was referring to larger, 1-2L food containers (which I’ve only seen with plastic/rubber lids).
