Learn how to make tempeh at home with just 3 ingredients! Homemade tempeh is easy to make and tastes so much better than the store-bought. Follow this step-by-step recipe to make tempeh in the Instant Pot!
📘 What Is Tempeh
Tempeh is an Indonesian food prepared from fermented soybeans. As opposed to tofu, tempeh is prepared from whole soybeans that are bound together by a white mold growing between each bean.
Tempeh is high in protein, healthy, and versatile!
⭐️ Why You Will Love It
If you have never made your own tempeh, you should definitely try! It’s not as complicated as it seems and requires very little active time. Plus, it tastes so much better than store-bought (no bitterness or aftertaste)! It’s also budget-friendly and makes a fun experiment!
Instant Pot Benefits
Making tempeh in the Instant Pot is not only easier, but it’s also quicker. Obviously, it still requires several hours to incubate, but the pressure cooker simplifies the whole process.
So, what are the advantages of making tempeh in the Instant Pot?
- You don’t have to soak the beans! Just rinse and pressure cook.
- Beans cook a lot faster and require less attention. This is the main advantage to me, I used to cook beans on the stovetop, and it took over 1 hour and constant attention, checking from time to time to see if there was still enough water or if the beans were not overcooked.
- No oven is required for the incubation step. Yes, you read right! Thanks to the yogurt mode of the Instant Pot, the tempeh is at the perfect temperature, meaning the mold develops well. I used to incubate tempeh in my oven, meaning I couldn’t use it for 48H. Not good when you have a cookie craving…Problem solved with the Instant Pot!
Ready to make your own tempeh? Let’s do it!
🥣 How to Make It
You will only need 3 ingredients:
- Soybeans – Preferably non-GMO soybeans. I personally went with peeled split soybeans here.
- Tempeh starter – It is sold as a powder, and a little goes a long way! Tempeh starter will keep in the fridge for years. You can order tempeh starter online.
- White vinegar – Regular white vinegar or rice vinegar either will work.
1. Cooking the Soybeans
Start by pressure-cooking the soybeans for 40 minutes. No soaking is needed. Just rinse the beans, cover them with water, and pressure cook in the Instant Pot.
To speed up the process even more, I used peeled split soybeans. They don’t only cook faster, but they also do not require peeling, which is usually the most time-consuming step when making tempeh from whole soybeans. If you can’t find split and peeled soybeans, there is an extra step you will have to do. Check out the recipe notes.
Once your soybeans are cooked and soft, the next step is to pat them dry. This step is essential as the mold won’t grow well if there is too much moisture. I usually spread the beans on a clean kitchen towel and let it sit for 15-20 minutes. Then top with another kitchen towel and press slightly to absorb excess moisture.
Next, stir in a tablespoon of white vinegar. The vinegar will lower the PH and prevent bad mold from growing. Sprinkle the tempeh starter and mix well to coat the soybeans before transferring them to freezer bags.
Tip: Make sure to pack the soybeans well in the freezer bags, you don’t want too much space between each soybean.
2. Incubating
To incubate, we will use the Instant Pot’s yogurt mode! Pour 1 cup of water into the liner, add the steamer rack, and place the soybean bags on the steamer so they don’t touch the water.
Set the Instant Pot on yogurt mode and let it do its magic! After 16 hours, you can turn it off and let it incubate for another 24 hours. You don’t need the Instant Pot to generate heat anymore, as the mold will start to generate its own. It’s actually funny how the tempeh is still warm after 24 hours!
You will start to see white mold growing after about 18-20 hours (2 hours after you turn off the yogurt mode), and it will fully cover the beans after about 40 hours.
Finally, when your tempeh loaves are firm and completely white, transfer to the refrigerator and use them as you wish!
This recipe yields two tempeh loaves of about 13 ounces. If you like tempeh as much as I do, it won’t last long. Otherwise, it freezes very well and will keep for months in the freezer. For those of you who eat soy-free, check out my chickpea tempeh recipe. The base is basically the same.
🌯 Where to Use It
Tempeh is super versatile and can be used:
- Sautéed: You can marinate diced or sliced tempeh in your favorite marinade and then sauté in a skillet until golden brown. Then, it can be added to vegetable stir-fries, noodles, or soups like this Tempeh Khao Soi. It’s also delicious in sandwiches or in wraps.
- Fried: Tempeh can be deep-fried for a crispy texture.
- Grilled: Tempeh is also perfect for grilling! It holds up well on the grill and can be charred. These Sesame & Peanut Tempeh Skewers are one of my favorites!
💬 FAQ

How to Make Tempeh in the Instant Pot
Equipment
Ingredients
- 2 cups split and peeled soybeans see notes for whole soybeans
- 6 cups water
- 1 tbsp white rice vinegar
- 1 tsp tempeh starter
Instructions
- Rinse the soybeans under cold water. Transfer to the Instant Pot liner. Cover with the water and close the lid. Set the valve to "Sealing."
- Pressure cook for 40 minutes and let the pressure release naturally (about 25 minutes). Once there is no more pressure, open the Instant Pot and drain the cooked soybeans.
- Transfer the cooked soybeans to a clean kitchen towel and let dry for 20 minutes. The soybeans should not be wet. If they still appear too wet, top them with another clean kitchen towel and press a bit to absorb excess water.
- Transfer the soybeans to a large mixing bowl. Add the rice vinegar and stir using a wooden spoon. Sprinkle the tempeh starter and stir again until well combined.
- Take two freezer bags and pierce them using a fork or a chopstick at 1-inch intervals. Divide the soybeans into the freezer bags and pack them well. Then fold the rest of the bag over the soybeans to keep it tight.
- Wash the Instant Pot liner. Place 1 cup of water in the bottom and top with the steam rack. Place the two tempeh loaves on the steamer. Cover with a glass lid (or use the Instant Pot lid if you don't have a large glass lid).
- Press the Yogurt button 3 times to set it to "Less" mode. Set the timer for 16 hours.
- After 16 hours, turn off the Instant Pot. You should start to see some white mold appearing. Remove the excess water from the lid using a paper towel. Place the lid back into place and let the tempeh incubate for another 24 hours.
- After 24 hours, the tempeh should be fully covered with white mold and bind the soybeans together into a firm cake. You can now place it in the refrigerator and use as you wish!
- Tempeh will keep for up to 2 weeks in the refrigerator or 6 months in the freezer.

Did anyone else’s smell really bad during the process? It’s starting to grow mold but it’s already been over 24 hours and idk if this is right…
What do you mean by bad smell? It should have a mushroom scent (a bit like a camembert).
What size freezer bags did you use?
I used “small-size” freezer bag that I folded in half. The size doesn’t really matter, use what you have and fold them or cut as needed.
Hi. I tend to cook by scale. How heavy are two cups of (uncooked) soybeans, approximately?
Hi Trang,
2 cups of uncooked soybeans will equal to approximately 360g. Hope this helps!
Hi. I’ve read that making tempeh requires air circulation. Does the Instant Pot allow for air circulation?
Hi Kate,
I am not sure if the Instant Pot allows air circulation but I never had any trouble making tempeh in the Instant Pot.
I made this recipe today. It took 2 hours to dehull the soybeans. Despite the good directions, I will have to achieve enlightenment before I try this again unless there’s some work-around. Difficult to find hulled soybeans online. One recipe fits into 2 1-quart freezer bags. Is there an extra step that will make this easier?
I’m afraid there is not. If you want to save time, the only option is to start with hulled soybeans.
I’m not able to get dehulled soy beans so I did the extra step and soaked first. I then cooked for 40 minutes which was far too long. I think the cooking time for soaked beans should be halved.
Thanks for your feedback Lisa, I’ll make sure to try again with whole soy beans and adjust the cooking time accordingly.
Great vid and very helpful. I have seen other versions in which (a) no water has been used during the fermentation process and (b) the pot has been left on the “Low” setting from the time mould has started forming u til the end product. If the IP is switched off, is fermentation guaranteed to continue?
It will continue if the mold is already well developed. Usually at this point, the heat from the tempeh itself will allow the mold to develop without any other heat source.
I tried making natto in my instant pot and it turned out very wet – am concerned if I use the lid which seals, that it will do the same thing to the tempeh. Can I put any glass lid over if it covers the pot – I don’t have one that fits exactly. Would appreciate your input. Cheers
Yes, I usually use a glass lid too. Just be aware that it will also produce steam so you will have to pat it dry from time to time.
Super recipe. Enjoy the mild and somewhat sweet taste. I don’t buy premade food and appreciate finding this recipe. Many thanks.
You are welcome!
My employer had served many different cuisines that were “complimentary” during Covid Days so I tried many World Cuisine dishes. I searched and followed this recipe since my wife bought a Magic Pot or whatever you call it. The recipe (16hrs at 109F) didn’t quite make it as I needed to “incubate” within the Insta Pot another ~24hr – with no heat – I was worried to overcook it – until I saw the two punctured freezer bags become white inside. I froze them within non-perforated bags and I must say about 9mos later I remembered my adventure and I took one out, partially defrosted it, cut it into cubes, tossed in corn flour, and then sprayed generously with olive oil and put them on my barbecue grill over a perforated tray and they came out so crispy and delicious! This was a teal treat to go down this culinary pathway and I def want to do it again as I have more Tempeh Starter dormant in the fridge. I took many photos but alas I cannot share. Cheers!
Yes, it can sometimes take longer for the mold to develop, depending on the temperature.
Thanks for your feedback!
Is it possible to follow these instructions using chickpeas? Isee your chickpea tempeh recipe has slightly different ratios
Yes, this recipe should definitely work with chickpeas as well!
Using the instant pot as an incubator for tempeh is a great idea. Thank you. Now I don’t need to go out and buy an incubator. It worked perfectly.
You are welcome Roger 😉
For me, The temperature was a great issue for making tempeh.
Tempeh is fussy! It needs to ferment at between 85°F and 90°F. Much cooler and the mycelium won’t grow (giving rise to undesirable microorganisms to grow instead) But I was always confused between 85F to90F.
Thomas I am a fan of your recipes and always tell friends about them. I love how you push us to try new things.
I recently ran across a couple of recipes using Pumfu (pumpkins seed tofu) and I’d love to know how to make it if you’re ever inclined.
Please know that we know a lot of hard work goes into your recipes, testing, testing and more testing and we all appreciate it!!
Hi Annie,
Thanks for your kind words 🙂
It’s the first time I hear about Pumfu, but I’m really intrigued! Thanks for sharing 🙂 I will definitely add this to my list!
Hi, my lowest Instant Pot setting is 91 degrees F. Is that too hot? I have made two failed batches and I’m wondering if it’s too hot. It also gets quite damp in the IP with the water put in initially. Both times, I had a lot of white but the beans were only partially covered with white and the loaves were still soft enough to break apart easily after 48 hours. They also started to smell bad, like feet, so I threw them out. Any suggestions? Thank you.
Hi Lilian,
91F should be okay, but I would stop it as soon as the tempeh starts to produce its own heat, usually after 36 hours. Sometimes tempeh can take up to 72 hours to be ready, so let it incubate for a longer period of time if the loaf is not firm enough. Regarding the smell, it should smell like camembert/mushrooms (which some people refer to smelling like feet), so I am not exactly sure if your tempeh went bad or not.
Thank you so much for posting this recipe! I can’t wait to buy an Instant Pot and make Tempeh this easier way! I saw a comment that said dried hulled split soybeans can be found in EBay. I don’t know how old that post is, but has anyone been able to find them? I can’t find them on EBay. Thanks so much!
I DID IT!!!! The hulling process was pretty tedious – I can totally see the benefit of buying them pre-hulled. But, super thrilled with how well it turned out. Thank you for such great instructions!!!!!
Thanks so much for your feedback Josie!
Yes, pre-hulled are not available everywhere but it’s worth finding it!
Espectacular el resultado!! Definitivamente, no vuelvo a comprar tempeh en la tienda, este es mucho mejor. Gracias!
¡De nada!
Hi!! Thank you for taking the time to share how you made Temph in the instant pot. I am so excited to try this. I have never made temph, and I feel the part that was a little confusing to me was regulating the temperature during the fermenting process.
My question is, have you ever made your own Temph starter in the insta pot using the yogurt mode? I have been reading about how to make my own starter and I am guessing you could use the insta pot to produce the started also.
Hi Leslie!
I have never tried making my own starter, I didn’t even know it was possible!
What size IP did you use? I have a 6 qt but only have room for 4 small bags of tempeh using a trivet and a taller trivet to keep them separate. The tempeh was delicious. I need to be able to make it in larger quantities.
How large is your IP. I have a 6 qt. There is no way I can fit two of those bags in the IP on a trivet. So, I use a second trivet for the second bag. Finding halved/hulled soybeans is now a prority.
I make tempeh in 3 cup Sterilite containers with holes drilled into the container bottom and lid. I steam my tempeh once it is ready to harvest so I found these steamer trays on Amazon. Using the trivet that comes with your IP you can stack two steamer trays in a 6 quart IP.

Do you have to wrap in plastic? I don’t keep any in my house. Can I use a beeswax cloth perhaps?
I only tried with plastic, however some readers had success using glass containers (check the comments).
I have made this recipe several times (rated it 5 stars), and I’m back to share a couple of things I’ve learned in case it helps anyone:
1- For anyone using whole soybeans, I’ve figured out a quick way to de-hull. First, I soak the dried beans in the fridge overnight. The next day, I simmer them in water for about 20 mins. Then, I turn off the heat and use a potato masher with a pressing and twisting motion (similar to mashing potatoes). Less than 5 mins of this removes over 90% of the hulls and splits most of the beans without breaking them. After that, you need to pour the hulls out to discard. As for cooking, I do it on the stovetop for 2 hrs so I can’t speak to how long to put them in the IP for, but there are probably resources online that say how long to cook soaked beans for.
2- I believe Arthur also mentioned this somewhere, but if you’ve done everything correctly and the mold isn’t growing, it could be that your starter is bad. In one experience, I noticed that something was wrong when the loaves were not staying warm after the Instant Pot yogurt cycle had ended. It was due to the bad starter batch.
LOVE this recipe, I can’t wait to try it! I don’t have an InstantPot, but have Insignia, which does not have the yogurt function. Is there an alternative I can use?
If you can set it to a temperature of 86°F (30°C), or find a spot with that temperature, like an oven with the light on, you should be able to incubate the tempeh.
I made a tempeh incubator by using a Coleman 24-Can Party Stacker Cooler, a Hydrofarm seedling mat and Hydrofarm thermostat, a cooling rack for a half-sheet pan, and a couple of aluminum loaf pans. The seedling mat goes in followed by the loaf pans on either side. These help elevate the cooling rack off the mat and you can add some water to them if you believe you need some extra humidity. Only thing left to do is to use the suction cup to attach the temperature sensor for the thermostat to the side of the container and then set it to 88 degrees. The cooler gives you ample room inside for containers, a pan, or bags to incubate.
Hi Thomas, I’m trying this and my tempeh has been incubating for 20+ hours and no mold. I let my beans lay out to dry over night because I didn’t have the tempeh starter yet so they got quite dried out. Do you think that’s why it’s not growing mold?
Also had the same issue with soaking beans, I got way more than 2 cups so I measured out 2 cups of split beans after cooking.
Hi Emily,
Yes I think you let the beans dry too much, there should still be a little bit of moisture for the mold to grow well.
Hi i used instant pot but the tempeh became wet.
And spores did not show up. anything missing? thx
Hi,
I would need more details, did you follow exactly the recipe? Also, did you let the beans dry enough before transferring to bags?
May i ask if we pressure cook in hugh setting or low setting the bean for 40mins in IP after we soak it and peel its skin? Will it not be too mushy? How clean should the bean be? If there are some skin left is this a problem? I have the ultra IP
You want to pressure cook on high. It’s not mushy after 40 mins from my experience.
It’s okay if there are still some skins left, it doesn’t have to be perfect 🙂

I’ve attempted this recipe, but I didn’t dry the beans enough. It’s been over 16 hours and there is no mold – plus the inside of the baggies have visible water droplets. I did open the lid a couple of times to check on the loafs and dry the glass lid – did this contribute to the moisture content?
Be aware it is normal to see condensation on the glass lid during the incubation process. You can always put a kitchen towel under the glass lid so any water drops coming off the lid will not drip down on the baggies. If you believe you did not dry the beans adequately there may not be anything you can do to rescue this batch but there is nothing wrong with letting it go a few more hours. If you are not seeing anything after 36 hours I would toss out what you have and start again. Be aware that during the incubation process as the tempeh starts generating its own heat it will give off moisture.
You can also let your nose be your guide. While it is normal that you may smell a slight odor of ammonia during the incubation process if you start smelling an overpowering odor of ammonia that is a bad sign.

I ended up cooking too many beans initially and put what I didn’t use in the freezer – so not a total wash.
Condensation is normal because of the temperature, but you should not see too much inside the bags though.
If no mold has grown after the incubation time, I’m afraid there is not much you can do anymore.
It worked ! I used a towel under the instant pot lid and it seemed to create the right temp for low yoghurt setting. Thank you!
You’re welcome Sebastiaan!
