What is Kecap Manis?
Kecap Manis (ketjap manis) is a popular sweet soy sauce from Indonesia. You may know it as the sweet dark sauce in a packet of mie goreng, used it in dishes like nasi gila or squeezed it on top of a big bowl of bakso soup.
At local supermarkets the most popular brands to look out for are the red bottle – ABC Kecap Manis and the blue bottle – Bango Kecap Manis.
What You’ll Need
- Soy Sauce – Use regular or light soy sauce for best results. If you want a sweeter sauce, use reduced salt soy sauce or add more sugar.
- Sugar – Brown sugar will work great, or use the more traditional palm sugar if you have it. Molasses or golden syrup also make great substitutes.

How to make homemade Indonesian sweet soy sauce:
1. 2. 3.
- Place the soy sauce and brown sugar into a medium saucepan over medium-high heat.
- Bring to a boil, it will bubble up quite a bit, so stir as you go to avoid any sticking. Important: Remove from heat immediately if it starts to boil over, then reduce the heat slightly to avoid a repeat.
- Continue boiling for around 7 minutes. You’ll notice the sauce reduces quite a bit. Turn the heat off and allow to thicken on standing.
Wandercook’s Tips
- Keep Watch – It’s so easy for this sauce to boil over, we can’t stress enough to keep watch!
- Storage – Once made, store in a clean jar in the fridge. It should last well over a month if only using sugar and soy sauce.
FAQs
The best substitute if using in a dish would be regular soy sauce and sugar without cooking it down, to give both the salty and sweetness. Next options would be to use hoisin sauce or oyster sauce.
Yes! It’s sweet AND salty. “Manis” literally translates to sweet in Indonesian.
Nothing, it is the same sauce. Sweet Soy Sauce is the English name, and Kecap Manis is the Indonesian name for the sauce.
Variations

02/03/2023 at 10:30 pmI had just gotten a new cookbook, and found myself scrambling. Drunken Noodles — I found everything I needed but the sweet soy sauce. Soy sauce comes in a sweet variety?!?!?! I had never known. None of the markets around me carry it so I was at a loss. To google I turned, and Google did not disappoint. This recipe worked very well, and came together so easily. Keeping this one in my recipe box for sure!
