Caramelised Onion Potato Salad

I do love a traditional style potato salad. But I also like to veer from the norm. This Thermomix potato salad is a refreshing change from the usual versions of this popular side dish.

Being a Greek yoghurt based dressing rather than mayonnaise keeps it on the lighter side. The caramelised onion gives a beautiful tang and sweetness.

First Things First: What We Need to Make This Thermomix Potato Salad

I like red skinned varieties of potatoes. I find they’re really versatile and do make a great potato salad.

Red Onion

I prefer red onion over brown in something like this. It is sweeter and lends itself more to things where onion is more than just a bit of flavour. Onion needs to shine when a recipe has it in the title!

Red Capsicum

Again this adds some sweetness and nice flavour.

Dressing Ingredients: Rapadura, Balsamic Vinegar, Yoghurt, Salt

The combination of ingredients in this dressing are sweet, sour, salty and creamy! The quantities of each ingredient is just the right amount to make a well balanced, tasty dressing that clings to the potatoes.
