14 Insulated Food Jars (That Keep Foods Hot & Cold)

Posted in School Supplies.

Time to lift your lunchbox game? I know the feeling. When the kids started complaining the yoghurt was lukewarm and the sandwiches came back all squishy I knew it was time to get out of this food rut and I got an insulated food jar. And boy did it open a huge range of new options.

We’re talking frosty smoothies staying refreshingly icy, yummy pasta staying piping hot and snacks surviving the wild ride to recess. Whether packing last night’s leftovers or keeping the freezer stocked with microwaveable lunches to thaw and go, you can send everything from soup to spagbol to school in a kids’ thermos.

So put on your chef’s hat, grab your spork and let’s dive in as we round up the most popular food containers for keeping food hot, and cold!

Ask yourself before hitting the shops

  • Will it need to hold both hot and cold foods?
  • Are they leakproof for liquid (yummy soups anyone?)
  • Will it stay hot until lunchtime?
  • Is the jar dishwasher safe?
  • Does it fit in your little one’s lunch bag?
  • Can your child open and close it themselves?
  • Does it come with a cutlery attachment?

MGV tip


Want to keep your food warmer for longer? Preheat your insulated food jar by filling it with boiling water, and leave for five minutes before pouring out and adding hot food.
