We are the kind of family that would order extra sweet and sour sauce, whenever we ordered Chinese takeout. Yup, we love the stuff that much. Of course sweet and sour sauce is loaded with sugar, so what do I do? I make my own sugar free sweet and sour sauce of course!

Why it works

  • We use lakanto’s golden monk fruit sweetener to make the ‘sweet’ in this keto sweet and sour sauce recipe, and for the best flavour possible!
  • It super easy to make and ready in under 10 minutes!
  • No sugar added ketchup and apple cider vinegar bring a ton of flavour to this sugar free sweet and sour, all while keeping it on the low carb side.

Ingredients

  • sweetener
  • apple cider vinegar
  • no sugar added ketchup
  • water
  • soy sauce
  • sesame oil
  • xanthan gum

Sweetener – We use Lakanto’s Golden Monk Fruit Sweetener in this keto sweet and sour sauce because it has, in my opinion, the very best flavour! I like to use it in place of brown sugar and find it has no aftertaste.

No Sugar Added Ketchup – Ketchup can be heavily loaded with sugar, so be sure to choose one that has no added sugar.

A dish of each: sesame oil, xanthan gum, water, apple cider vinegar, almond flour, ketchup and soy sauce.

How to make Keto Sweet and Sour Sauce

Combine the sesame oil and xanthan gum in a medium saucepan and stir until the xanthan gum is fully mixed with the oil. Slowly whisk in the apple cider vinegar so that it mixes in well with the xanthan gum, then pour in the water, soy sauce, ketchup and sweetener.

Bring the sauce to a boil, reduce to a simmer and cook until thick, 1-2 minutes. Pour over your favourite meal or use for dipping!

  1. Could you use equal parts tomato paste in place of reduced sugar ketchup? I’m not a fan of artificial sweeteners and I can’t find a sugar-free ketchup without them. Thanks.

    • Hey Chris, I totally get that. Ketchup is made with pureed tomatoes, sugar and spices, mustard and vinegar. You could try replacing the ketchup with pureed tomatoes, but it will be lacking sweetness and flavour. If you feel up to the challenge, you could make yourself some sugar free ketchup, otherwise I recommend you try using pureed tomatoes rather than tomato paste.
      Here is a recipe from SugarFreeLondoner I have used and like: https://sugarfreelondoner.com/sugar-free-ketchup/
      Hope it works out for you!

    This sweet and sour sauce sounds SO GOOD for chicken! And paired with rice like you have it would be perfect. Saving this to try ASAP!

    Definitely love the idea of using monk fruit sweetener as a sugar substitute… The sauce on those meatballs sold me, so I’ll be looking forward to trying this

    This keto Sweet and sour sauce is fabulous! I needed a sauce for wings and came across this little gem and my family loved it. They didn’t even know it was keto friendly because it was so delicious. Thanks for a great recipe.

    What a great recipe to have handy — nothing like a great sweet and sour sauce to perk up several types of dishes. Not only can you add this as an ingredient to a main dish but a dipping sauce. So yummy!!

  6. 5 stars
    Yum! I’m definitely the extra sauce type too! The fruit sweetener seems like a good substitution to get that same tasty flavor you would from Chinese takeout.

    I appreciate the reduced sugar recipe, as I’m not a fan of overly sweet dishes. Do you have a reco for no-sugar added ketchup you like?

    • Yes! I prefer to use Heinz, as it is easy to find and tastes great. There are others that are better for you such as Primal’s organic unsweetened ketchup, if you prefer.

  9. 5 stars
    I like to make sweet and sour sauce in bulk and use it as and when needed. It makes life so much easier. I love your variation and fortunately I have all the ingredients. Yay! Making it right now.

  10. I’m not keto but I’ve always hated the amount of sugar in a sweet and sour sauce. I’d like to give this version a try sometime!
