Rice Cooker or Instant Pot Ketupat and Lontong (Rice Cakes)- Learn how to easily make ketupat or lontong (nasi impit) using rice cooker or Instant Pot. No more wrapping and hours of boiling.
I’ve never made ketupat from scratch but I have made lontong from scratch. While it’s not difficult, but sure takes a long time to boil the rice and not to mention some of them might burst during cooking if I filled up too much rice in the banana wrap. Long story short, I don’t like to make lontong from scratch for those reasons.
WHY YOU WILL LIKE RICE COOKER OR INSTANT POT LONTONG AND KETUPAT
Now this rice cooker or instant pot lontong and ketupat is life-changing. It’s quick to make and pretty effortless
Yeah…for real, time-saving! I used to have to boil lontong for 2-3 hours
3. Most people own either rice cooker or Instant Pot
In this modern day, either one of this equipment has become kitchen essential. You can use the pressure cooker feature of Instant Pot or the rice feature on it. Pretty cool!
ARE KETUPAT AND LONTONG THE SAME?
Both ketupat and lontong are made with white rice. Ketupat is usually wrapped in a case made of coconut leaves that are weaved into beautiful patterns and then boiled. Lontong is usually wrapped in banana leaves and then boiled. So, they are pretty much the same but the difference is on the wrapping.
THIS RECIPE WORKS FOR BOTH KETUPAT AND LONTONGSince no wrapping is needed, technically this recipe can be used in a recipe that calls for ketupat or lontong.
RICE TO WATER RATIO
I’ve tried to make this rice cooker ketupat or lontong several times with different ratios. Mom told me that this really depends on the type of rice and also whether the rice is “new” or “old”. I used Thai jasmine rice.
Mom used 1:4 ratio and that’s my starting point and here’s what I found out:
RICE : WATER RATIO
1:4 = The rice cakes came out way too soft for me. My mom in Indonesia used regular white long grain rice and hers came out perfect. So she sticks with this 1:4 ratio
1:3 = The rice cakes came out much firmer now but still a tad too sticky for my liking
1:2 = This works perfectly for me
Mom said “older” rice absorbs more water compared to “newer” batch of rice grains. My mom said in Indonesia, they sold rice specifically for making lontong, which is usually cheaper and lower quality and absorbs lots of water.You definitely need to play around with the ratio, but I would say you can start with the middle, 1:3 ratio
HOW TO MAKE KETUPAT AND LONTONG USING RICE COOKER OR INSTANT POT
I guess you can almost call this ketupat instant or lontong instant. Instant in the sense that no wrapping and long hours of cooking to make this Indonesian rice cakes. Here’s how:
1. Rinse your rice in several changes of water
This part is to get rid of any excess starch and impurities. Drain off completely so that your water measurement is accurate
2. Transfer to inner pot of rice cooker or instant pot and add water
I use rice to water ratio of 1:2 (read explanation above)
3. Cook on a rice cooker or instant pot
RICE COOKER: I use the white rice setting on the rice cooker, which takes about 20 minutes to cook
INSTANT POT PRESSURE COOKER FEATURE: Turn the steam release valve to sealing, press pressure cooker then high pressure and set timer to 3 minutes and then wait 10 minutes to release pressure fully
INSTANT POT RICE FEATURE : Turn the steam release valve to sealing, press RICE and the timer will be set automatically
4. Mold the rice while warm
Once the rice is done cooking, immediately transfer to a heat-proof loaf pan or container and use the rice paddle to spread, press and REALLY push the rice to pack them down
5. Use parchment paper to really pack it down
Once all the rice is in the container, cover with a piece of parchment paper and use your palms to really push them down to make sure you pack it down so the rice really sticks to each other to form a large piece of cake
6. This is how it will look like
7. Let the ketupat or lontong cool down
You can let them cool down at room temperature or let them cool down a bit and then cover with plastic wrap and place in the refrigerator for 1 hour before cutting.

Marvellina, I tried your instapot version with 1:3 using Jasmine rice and the result was fantastic! THank you so much for sharing.
Hi Chitra, I’m glad to know that 🙂 Thank you for your feedback!
I lived on a little island in the Philippines as a kid, and at weddings they would send people home with what they called “katompat” which looked very much like the Indonesian “ketupat”. However, the bundles were always greasy and a bit salty. They tasted great. I’m wondering if they might have boiled them in salted coconut milk? Have you tried making this rice cooker version with coconut milk instead of water? Also, I wonder if adding some lemongrass and kaffir lime leaves into the cooking pot (on top) might be delicious too. Thanks!
Hi there, I think I know what you are referring to. There’s a version boiled in coconut milk and yes you can add salt and definitely lemongrass and kaffir lime leaves will add amazing flavor. I would mix them in the rice before cooking. For plain lontong (rice cake) we usually don’t do coconut milk and other herbs.
What a nice way of serving rice, that bowl looks delicious!
