Caramelised onions may just be one of our favourite things to put inside a burger and making the perfect caramelised onions can be somewhat of an art form- but one we’d like to think we’d gotten pretty good at!  We’d like to share with you our favourite recipe for caramelised onions. The caramelisation process can take a little while but bare with us and you won’t regret the results! Anyone can do it- you just need a frying pan, maple syrup, oil, salt and onions. Just make sure you don’t miss out any of the steps and without too much effort you will get the perfect caramelised onions every time! You can also do this recipe without the maple syrup- but we like to add it to make the sweet onions taste super indulgent!

Prep time: 5 minutes  | Cook Time: 30-45 minutes | Total time: 35- 50 minutes

(Serves: 2-4 people)



  • Olive oil

  • 2 brown onions

  • 2 or more tablespoons maple syrup, to taste

  • Salt


  1. Start by chopping the onions into fine slices.

  2. Now heat up a good glug of the olive oil in a frying pan, on a medium-low heat.

  3. Once the oil is hot enough, add the onions to the pan.

  4. Let the onions simmer on a low-medium heat, until they begin to appear transparent and soft.

  5. Now it’s time to add a good pinch of salt.

    This salt will help the onions begin to sweat. When onions sweat, they will release liquid into the pan.

  6. Once there is a fair amount of liquid in the pan, turn the heat up high in order to evaporate all of this liquid!

    The liquid needs to evaporate in order for the onions to begin caramelising properly.

  7. It’s time to caramelise those onions!

    Once all of the liquid has disappeared, turn the heat back down to medium low to begin the caramelisation process.

  8. Once the onions have started to look nice and caramelised, add the maple syrup and give it a nice stir!

  9. Cook for another 1-2 minutes or until the onions are caramelised to perfection! Serve inside a burger on top of one of our yummy plant based patties, or along side our corn fritters for brekkie!
