Glass food containers vs plastic – worth the switch?

BusyWeekPlanner · 22/12/2025 07:44

I’d love some honest opinions please.
We batch cook and store a lot of leftovers, and I’m getting increasingly fed up with plastic containers warping, staining or holding smells after a while.
I’m thinking about switching to glass but would really like to hear from people who’ve done it long-term.
What’s been good? What’s been annoying? Anything you wish you’d known before switching?

We have a mix of both but I prefer the glass ones , I bought a really good set in Costco a couple of years back .

I've used glass for years and love them! Recently switched to the stainless steel ones from Black + Blum which are microwave safe, would highly recommend if you are concerned about the glass containers being heavy or breaking.

I've gradually replaced our plastic ones with glass and much prefer them. We have stainless steel bento boxes for lunches so that's not a factor for us.

Plastic ones break anyway if they fall out of the freezer, so not much difference there, I don't think, and I don't find the weight onerous. They're a lot cleaner and obviously last longer. I like the freezer to oven facility.

I switched from plastic to glass, ceramic, and stainless steel some years ago, but I'm now switching away from glass and ceramic as my grip isn't so good and I've broken a lot of it.
Stainless steel works in the freezer, oven and fridge, and I tend to save plastic for the microwave. I have a couple of sets of stretchy silicon lids and they work just fine. I now buy stainless steel bowls to fit the stretchy lids, I got my current set on ebay but they sell them in most Asian supermarkets.

I much prefer glass but hand wash the lids as they tend to stain in the dishwasher. Also can cook in them.

Hello39 · 23/12/2025 15:41

I use both.
Plastic for lunches etc.
Usually glass for leftovers.
Usually glass if I'm freezing anything.

Some of the glass ones have chipped so nothing lasts forever

CaliRach · 23/12/2025 15:48

I use our remaining plastic (not buying anything new) for chilled things, and freezing. I don't let warm food near plastic these days, nor would I use it in a microwave.

We've ditched all the non stick stuff as well. Just cast iron and stainless steel for cooking.

stargirl1701 · 23/12/2025 16:06

We’ve been using glass for at least 15 years. Straight shoulder Kilner jars and Pyrex with plastic lids. The plastic lids don’t touch the food and we wash them by hand.

HoppyToad · 23/12/2025 19:05

I switched years ago, no regrets at all. Yes they're heavier, but they clean so, so well. I've had no issues with them at all. I have the Sistema ones.

Evidence is mounting that microplastics damage human health significantly. It's not just the brain clogging effects leading to dementia but damage to nearly every organ in the body. Advice is not to drink water from a plastic bottle unless it's an emergency. Plastics that have anything hot put in them are an even bigger hazard. I'd like to see a complete ban on takeaway coffee cups. So yes, glass, despite the storage challenge.

Bottlesofrumonthewall · 23/12/2025 21:33

Sorry - Can I just say there’s plastic in and on everything anyway, from the toothpaste tubes to those plastic tubs that fruit come in. Unless you’re going to your local farm and home cooking everything - which most people don’t - Then I don’t see how swapping from plastic tubs to glass to avoid plastic is going to make very much of a difference?

HorrorFan81 · 23/12/2025 23:41

We've used glass for years, much prefer them for storing and reheating. Do have some plastics ones for taking out and about since glass is pretty heavy

Ihavelostthegame · 24/12/2025 02:28

I love the ikea 365 range. I also use the suber cube 1 cup freezer containers to freeze single portion meals in blocks which incidentally are exactly the right size for the small square ikea 365 glass dishes. So I freeze portions in the cubes and then pop one in a dish ready to defrost.

Glass all the way. Especially for oily food. I even refuse to buy olive oil in plastic bottles.

We switched because I got fed up of plastic shit that falls apart - no matter the brand.

Glass is to all intents and purposes infinitely re-usable. But the oil industry has to exist (apparently) so it's plastic, plastic, plastic. The nuclear waste of consumerism.

We have a mix, the glass ones still have plastic lids and most of the lids have cracked fairly quickly. I rarely buy plastic containers though - when we need a few more we just have a Chinese takeaway. Those plastics boxes would survive a war.

I’ve had both but prefer microwaveable stainless steel.

Which ones have you bought?

My pyrex ones are well over a decade old and the plastic lids still going strong.

@SerendipityJane

Pyrex isn't recyclable though I don't think?

Hence "re use".

Lasts forever though. I have dishes from the 60s.
