A container does not make unsafe food safe, but the right one helps you do the things that matter: cool leftovers quickly, keep air and cross-contamination away, and know at a glance what's what. This guide compares the main container types by what they are good for and what to check before you buy. We name no brands, rank no models and quote no prices, because the right choice depends on your fridge and your cooking.
Container types compared
| Type | Best for | Check before buying | Pairs well with |
|---|---|---|---|
| Airtight glass containers | Leftovers you will reheat; strong smells such as curry | Sizes, lid materials and dishwasher or microwave suitability vary by product, so check the maker's own instructions before relying on any container for oven, freezer or microwave use. | Leftover curry, leftover soup |
| Shallow meal-prep containers | Cooling cooked food quickly | A shallow layer, not a deep tub, is what speeds cooling | Cooked rice, cooked pasta |
| Fridge thermometer | Checking your fridge is at 5°C or below | A simple dial or digital probe is enough | Every storage page on this site |
| Vacuum sealer and bags | Freezer storage and portioning | Vacuum sealing is not a substitute for chilling: chilled food still has the same fridge limits | Freezing raw mince, freezing cooked chicken |
| Reusable produce bags | Salad leaves and herbs | Keep bags clean and dry between uses | Bagged salad, fresh herbs |
Our picks
Airtight glass containers
Glass does not hold on to smells or stains, and a clear container shows what's inside, which cuts the 'mystery leftovers' problem. Most glass dishes can go from fridge to microwave, but the lid is usually plastic: check which parts are oven-safe and never microwave with a sealed lid.
Check Price →Shallow meal-prep containers
Spread food out and it cools faster, which matters because the FSA advises chilling leftovers within 1 to 2 hours (rice within 1 hour). A shallow layer cools much more quickly than a deep tub of the same food.
Check Price →Fridge thermometer
Every storage time on this site assumes a fridge running at 0 to 5°C. Many home fridges quietly run warmer than the dial suggests, and a thermometer is the cheapest way to find out.
Check Price →Vacuum food sealer and bags
Removing air helps frozen food avoid freezer burn and makes portioning easy. It does not extend how long chilled food is safe in the fridge, so keep to the fridge limits on our storage pages.
Check Price →Reusable produce bags
Designed to keep salad leaves and herbs from sitting in their own moisture. A useful extra for fresh produce, but not a replacement for the use-by date on a bagged salad.

How to cool and store leftovers
- Cool food as quickly as you can: divide it into shallow containers and let the steam escape. Rice should be chilled within 1 hour.
- Get it into the fridge within 1 to 2 hours of cooking. After 2 hours at room temperature, bacteria can multiply fast.
- Keep the fridge at 5°C or below, and put a date on the lid.
- Eat chilled leftovers within 2 days, and reheat only once, until piping hot (75°C) all the way through.
- Freeze anything you will not finish in time, ideally on day one.
Common questions
Are glass or plastic containers better for the fridge?
Either can be safe. Glass resists staining and smells and can usually go in the microwave, while plastic is lighter and cheaper. Whichever you choose, make sure it is described as food-safe, that the lid seals properly, and that you stop using any container that is cracked, warped or scratched.
Does a vacuum sealer make food last longer in the fridge?
Not in terms of safety. Vacuum sealing helps frozen food avoid freezer burn, but chilled food still has to be eaten within the usual fridge limits, and some bacteria, including Listeria, can grow without oxygen. Follow the use-by date and our storage times.
Can I put hot food straight into a container in the fridge?
Let it cool for a short while first, spread out in a shallow container, then refrigerate within 1 to 2 hours of cooking. Putting a large hot pot in the fridge can warm everything around it, which is why shallow containers help.
How long do leftovers last in the fridge?
Under UK FSA and NHS advice, eat chilled cooked leftovers within 2 days, and cooked rice within 1 day. See our leftovers storage page for the detail.
