Caramelised Onions in the Thermomix

  • Author: The 4 Blades
  • Total Time: 35 minutes
  • Yield: approximately 1 cup of caramelised onions


We have been asked so many times about making caramelised onions in the thermo mixer! These are a beautiful balsamic version which are a perfect side to any hot breakfast. We served them with our Egg & Bacon Crêpe Cups – you must give them a go!

We think that caramelised onions are a great way to add a bit of ‘fancy’ to a recipe. Traditionally we have always done these on the stove, but we really wanted to try making caramelised onions in the Thermomix. So simple. Such minimal ‘everyday’ ingredients. So easy to make ahead of time.

The two big realisations we had were…

  1. It’s great that the Thermomix puts in the elbow grease stirring, while we were doing other things
  2. It does take longer to get the caramelised onions to have the nice texture that we all want – but it totally gets there, and with minimal involvement!

This recipe was featured in Episode 144 of the podcast, as an addition to a roast veggie quiche.
