Keto Sweet Chilli Sauce Ingredients

Chillies – I use a mix of serrano, jalapeño, and bishops crowns. If you do not want it to be spicy scrape out all the seeds and membranes from the chillies. Alternatively you can just use a tablespoon of chilli flakes for a milder sweet chilli sauce.

Sweetener – I use Sukrin Gold, but any sweetener can be used in this sauce.

Garlic – add more garlic if you wish, but remember to add the carbs as well.

Vinegar – I use apple cider vinegar but you can just use regular white vinegar if that is all you have.

How to make it

Trim the end off the chillies and de-seed if you want a milder sauce.

Add all ingredients to saucepan or Thermomix® and cook until sauce has thickened.

    This sweet chilli sauce is so easy to make!!
    I love the nice bit of heat but also that it’s sugar free. We had it with some philly cheese and seasoned crackers.
    Whole family loves this one and I love a quick delicious flavour paced sauce.
    Thanks Megan for another great recipe

    Please can you check measurement re Metric ‘cups’ to US cups. I dont understand how 1 metric cup for both Sukrin Gold and vinegar can be equivalent to 0.5 US cup and 0.25 US cup ? Thanks

    • Megan says:

      I will have to look at the plugin as it is automatically calculated. I believe a US cup is smaller than a metric cup but only by 20g

  • Laura says:

    Is it 1 x 5cm piece of ginger or 1 x 15cm piece of ginger

  • Suzi Delpopolo says:

    Hi I love the taste of this sweet chilli sauce, I’m just wondering why my Erythritol has re crystallised into chunks of sweetener on cooling and how to avoid this? It was great while warm but at room temp it now has chunks of sweetener. I’m in Australia and don’t have access to Sukrin yet but it’s mostly erithritol anyway right?

    • Megan Mad Creations Hub says:

      Hi Suzi, I am an Aussie too and Sukrin is available through the links online within Aus. I use powdered erythritol but unfortunately all keto sweeteners can recrystallise. Just give it is a little warmth from the microwave or in a pan and it will liquidise again.

  • Robert says:

    I have made this using Natvia instead of Sukrin. The sauce has set hard, looks like creamed honey… What would cause this?? Is it the sweetener I used or something else? Thanks

    • Megan Mad Creations Hub says:

      Hi Robert, if that was the only difference you made then maybe. That sounds really weird. If you heat it a little does it go back to a sauce consistency?

    Just made a double batch of this insanely good Sweet Chilli Sauce as we go through heaps here. Kicking myself that I haven’t made it sooner (it’s been on my to do list FOREVER). Thanks Megan for a fantastic easy recipe.
