This sugar free sweet chilli sauce recipe is wonderfully spicy, fragrant and tangy! It's a healthy homemade dipping sauce for any Asian favourites from spring rolls to chicken wings and fried calamari. Keto, low carb, gluten free and ready in only 15 minutes.
Hands up who else loves sweet chilli sauce? It's one of those condiments in Thai and Vietnamese cuisine that take dishes to the next level. It's great for dipping with various appetisers, but you can also mix it into stir-fries.
Unfortunately, the sweet chilli sauce you can buy in the shops contains HUGE amounts of sugar. Often, people are not even aware that they are consuming more sugar than they would have in a dessert when they use shop-bought condiments and sauces. Read the labels - you might be surprised.
After making this yummy homemade sugar free ketchup, a delicious keto teriyaki sauce and my sugar free BBQ sauce, I decided it was time to create a sugar free sweet chilli sauce recipe.

Ingredients
To make an authentic tasting sweet chilli sauce, you only need a few ingredients - red chilli, vinegar, garlic, sweetener, a salty flavouring sauce such as soy, tamari, coconut aminos or fish sauce plus water and a thickening/gelling agent.
I decided to add fresh grated ginger to the recipe, which lends a beautifully aromatic and zesty touch.
Substitutions
If you are a shortcut kind of person, you can substitute the fresh chilli with sambal oelek. This is an Indonesian chilli sauce which is widely available in supermarkets. Sambal contains a small amount of sugar, but 2 tablespoon will not significantly increase the net carb count.
You could also experiment with using sriracha sauce, but you will end up with a smooth sauce.
I have not yet tried the recipe with dried chilli flakes, though it should also work. Be cautious with the amount - I always find them to be very hot. 1 tablespoon should be plenty!
I decided to use coconut aminos in this recipe. This is a super tasty gluten free and vegan flavouring sauce I recently discovered (I LOVE to use it in salad dressings). It's often used in place of either soy sauce or tamari.
But if you're finding it hard to source, feel free to use soy or tamari instead. Tamari is gluten free as well.
Another upgrade option is to add 1 teaspoon of fish sauce to the mix. Fish sauce has a strong, salty and slightly pungent flavour. It is INCREDIBLE!
How To Make Sugar Free Sweet Chilli Sauce
It is really easy to make a homemade healthy sweet chilli sauce recipe.
All you need to do is let the ingredients cook until the flavours start to mingle - and after only 10 minutes you have a healthy, sweet, spicy, tangy sauce that will make you swoon whilst keeping your blood sugar and insulin levels perfectly stable.
Here are the basic steps:
STEP 1
Chop the red chilli, ginger and garlic. Add them to a pan together with the apple cider vinegar, coconut aminos and powdered sweetener.
STEP 2
Bring the mixture to a boil. Then reduce the heat and let the sauce bubble away on low heat for 5 minutes.
STEP 3
Mix the hot water with the xanthan gum. Blend well so there are no lumps. Add to the pan and cook for another 5 minutes or until the desired consistency is reached.
Be aware that the sauce will thicken further while it cools. Fill into a clean glass jar and let cool.
Expert Tips
I went for a mild red chilli. Mild chilli varieties are generally larger in size. You could use red jalapenos, for example. If in doubt, ask your greengrocer 😉
The rule of thumb is that the smaller the chilli, the hotter it is. If you decide to use Thai red chillies, for example, you should reduce the amount stated in the recipe to 1 ½ tablespoon (not packed) and ensure you remove all seeds.
Tip: Make sure that you wear gloves when chopping chilli. This counts especially for all of you who wear contact lenses like me. The last thing you want is to touch your eyes with remnants of chilli juice on your fingers!
Recipe FAQs
Instead of the xanthan gum you could use 1 teaspoon of finely ground (!!!) chia seeds to thicken the sauce. I have not tried chia seeds as a thickener in this recipe, but use them frequently to thicken sauces and jams.
I like apple cider vinegar because of all its health benefits and mild taste. It is possible to substitute it with white wine vinegar or rice vinegar although these are sharper in flavour and you may need to use less. Also, make sure the rice vinegar is not flavoured - this often means added sugar.
You can store your healthy sweet chilli sauce in the fridge for at least 2-3 weeks.
Allulose is great because it does not re-crystallise as it cools. However, most of the time I make the sauce with powdered erythritol.
Serve With
This sweet chili sauce is perfect as a dip for keto tortilla chips or keto chicken nuggets.
It is also wonderful over Vietnamese scrambled eggs and keto fried rice.
Storage
Store the sauce in an airtight container in the fridge. The vinegar in the recipe preserves it, making it stay fresh for several weeks.
If you store the sauce in the fridge, the erythritol might crystallise a little bit over time. I had a few crystals collecting on the edges of my jar after a few days, which did not bother me. But to get rid of the crystals, you can re-heat the sauce and let it cool back down to room temperature.

Made this yesterday to toss some baked chicken wings in. Delicious and very much missed since starting Keto. Thank you for this recipe. I made a double batch and have 1 still in the fridge.
Katrin Nürnberger
I love having a second dinner waiting in the fridge. Hurrah to double batches!
Mike
Not tried this recipe yet but I intend to.
Is it suitable for use in Stir Frying - for instance with some chicken and stir fry vegetables. It's a real quick meal and I love it with a chilli sauce, but the supermarket sachets can contain up to 50g of carbs (mostly sugar) for a 2 person serving.
Katrin Nürnberger
Yes, I've used it for stir-frying 🙂
Andra
I’ve found that a tablespoon or two of fermented pickle juice acts very well as a preservative for cold-stored condiments. I add it to my homemade ketchup and bbq sauce and haven’t had any go off yet before we were able to finish it.
Let the condiment cool a bit first before adding the pickle juice for the same reason you don’t put yeast into very hot water. I’ve never noticed that it has any effect on the flavor.
Cheers!
Katrin Nürnberger
That is such a great tip! Thank you so much for letting us know 🙂
Shimmy
Hello Katrin,
Could I use red chilli flakes instead of fresh? If so how much? Many thanks.
Katrin Nürnberger
Hi Shimmy, I find that dried chili flakes are much hotter than fresh chili. 1 tbsp should be plenty.
Neil Stevens
Thanks for all the fabulous recipes. They have been a real life saver for us - literally- in our need to switch to a low carb diet. So many to choose some days we just don't know what to cook!
My question about this fab sauce is : can I make a big batch and safely bottle it for later? The apv makes it acidic so I guess I could. Just wanted your thoughts and any tips. Thanks
Katrin
Hi Neil, I have kept mine in the fridge for quite a while and it was fine. I recon it was over 2 weeks. You do get a little more crystallisation over time from the erythritol, but it was not enough to bother me.
I cannot guarantee that you can make a batch and store it in several bottles (in the fridge) over months without them going off. My feeling is that you probably could, because of the acidity and provided you create a proper vacuum and used sterilised jars, but the honest answer is that I just don't know. It would be a sniff-and-taste situation.
Olive McGrath
This looks great. How long will this keep for?
Katrin
Hi Olive, I kept mine in the fridge for about 2 weeks, after that it was finished 🙂
Louise Allison
Wow! Wasted a fiver on a S-F sweet chilli sauce from Amazon - which was horrid!! THIS is da bomb! (Though possibly 4 large chilies has made it a bit spicy!! Thank you as always!!
Ruth
Only looking at these appetizing photos, I decided to make it. It was so easy, and the taste is really surprising. It's incredibly unique, tangy, spicy, and full of Asian flavour. I find no way to describe. For me it's the best chilli sauce I ever tried. Could get addicted to its taste.
Surely there are lots of other applications in the cuisine. I added a tsp to my rice to give it this particular spicy aromatic Asian flavour. Looked great and tasted fantastic. Can really recommend it.
What a great recipe. Thank you for sharing
Katrin
Hello Ruth, I bet it would be nice stirred into rice!
Brenda

I used to be able to buy a wonderful hot and sweet sauce, a la thailand, that I used on all sorts of things like potato or fish cakes. then it disappeared and I made my own chili syrup. but, now on keto despaired that i would ever have this sauce again. Voila! You have done it! thanks much
Katrin
I missed a good chilli sauce too.... hence this recipe. Let me know what you think of it if you try!!!
