How to get the most out of your Insulated Food Jar

Like a hug in the playground, a hot lunch will warm those little bellies on a cold day. So what’s the best way to send hot lunches with your little ones to school? Insulated Food Jars!

Packing warms lunches or leftovers is an easy way to add extra nutrition into the lunchbox while adding some great variety too! How do you get the most from your insulated food jar and how do you know which one is right for your kids? Let’s answer all of your food jar questions!


What should you pack in your Insulated Food Jar?

Insulated food jars aren’t just for packing hot foods! They can be used to keep food cold too, which means your food jar can be used all-year-round. Here are some of my favourite hot and cold food ideas.


  • Pasta
  • Noodles
  • Leftover stir fry
  • Soup
  • Risotto
  • Chicken Nuggets
  • Fried Rice
  •  Macaroni and Cheese


  • Yoghurt
  • Fruit Salad
  • Overnight Oats
  • Bircher muesli 
  • Pasta salad
  • Smoothie bowl
  • Custard
  • Salad

Should you pre-warm (or pre-cool) your Insulated Food Jar?

Yes! Just like a thermos, your food jar will stay hotter if it is pre-warmed. Fill your food jar with boiling water and allow it to sit for around 10 minutes, before pouring out and adding your food.

It is recommended that you heat your food hotter than if you were eating it straight away before adding to your food jar.

If you have pre-warmed your food jar, you can expect lunches packed at 7am will still be nice and warm by lunchtime! Likewise for chilled if you have packed a cold lunch and pre-chilled.
