It is not as straightforward as you would think to use your Instant Pot as a Slow Cooker. This guide walks you through the modifications you need to know when using your pressure cooker as a slow cooker so that you can have Instant Pot success!

The Instant Pot Slow Cooker function is not equivalent to the temperatures on a slow cooker, which can make using your instant pot like a slow cooker tricky.
Therefore, it is not as easy as hitting the slow cooker function on your Instant Pot and expecting the Instant Pot to cook the recipe just as a crockpot would.
While I briefly cover using the slow cooker function on my post covering Instant Pot Settings, this delves into the topic a bit more deeply, giving you the recipe for success when using an Instant Pot as a Slow Cooker.
How to Use Your Instant Pot as a Slow Cooker
To be perfectly honest with you, this is my least favorite setting on the Instant Pot. In fact, it is so finicky and takes longer to cook, that I have kept my crockpot to use when I want to slow cook something.
However, if you only have space for one appliance, I would still recommend purchasing the Instant Pot and with this guide, you CAN slow cook using your Instant Pot.
Instant Pot Slow Cooker Temperatures
- Low on the Instant Pot Slow Cooker Function is like keep warm on a traditional slow cooker.
- Medium on the Instant Pot Slow Cooker Function is like low on a traditional slow cooker.
- High on the Instant Pot Function is more like medium-high on a traditional slow cooker.
To further explain:
- The low setting on a crockpot is about 190-200 degrees Fand the high setting on a crockpot is between 225-275 degrees F.
- For the slow cooker function on your instant pot, the low is about 170 degrees F, normal is 200 degrees F, and the high is 210 degrees F.
Tips for Using Your Instant Pot as a Slow Cooker
- You still need 1 cup of water when slow cooking--this will help the Instant Pot to heat up properly.
- Hit your Slow Cooker Function on your Instant Pot and then hit the adjust button to change the setting to "normal" or "high."
- If you want to cook a recipe like you would on low in a slow cooker, adjust your slow cooker to "normal" on the slow cooker function and cook for as the recipe calls to cook on low.
- If you want to cook a recipe like you would on high in a slow cooker, adjust your slow cooker to "high" on the slow cooker function and cook for as long as the recipe states PLUS an additional 15 minutes for every hour.
- You can use a glass lid or the Instant Pot lid when using the slow cooker function. A glass lid will allow some of the liquid to evaporate, as a traditional slow cooker lid does.
- Because no pressure is reached, you do not need to worry about the position your vent knob is in. However, leave it on the venting position if you want some liquid to evaporate.
- The lid will not lock into place, as no pressure is reached and the temperature inside the inner pot is much lower than when under pressure.
- You can open your Instant Pot to stir during the cooking process, because again, no pressure is reached.
- Your Instant Pot will preheat for 10-15 minutes before it begins to actual slow cook anything. If it takes longer than that, hit cancel and try again.

If I want to halve the recipe do I need to decrease the cooking time?
Kristen Chidsey
Hi Sally! The cooking time will remain the same 🙂 Enjoy!
Patricia Hamilton Bell
Thank you for sharing this info. Have been wanted to try this but lacked any knowledge on how to go about it.
Kristen Chidsey
So happy this helped!
Kaya
Uggh, I can't get it to move out of preheat when slow cooking. I have the Duo Plus 3 QT
Kristen Chidsey
Hi Kaya! That is NOT Normal. For this model, after you hit slow cook and select the time and setting, after 10 seconds the cooking should start and you should hear 3 beeps to let you know it has begun. I would check to be sure you have not set the delay start on accident.
Cécile
Hi,
Same here, with the Instant pot pro… preheating lasts for 3h out of 4 and the actual cooking happen during the last hour. This is not slow cooking!
And I’m sure we haven’t used delay…
If someone had any suggestion, it would be appreciated ! Thanks.
Kristen Chidsey
Hi Cecile! Thank you for telling me your model. That will help me troubleshoot or determine that this model specifically is not good at slow cooking.
Jake
I have the same problem with my IP 8 quart. It just stays in preheat mode.
Kristen Chidsey
Try turning to saute for a minute and then switching to slow cooker.

Hi,
I found this very helpful
I was trying to render tallow and didn't have crockpot. So after reading this I set the instant pot to slow cook "Normal " for four hours added water and salt to render tallow hopefully it goes well in four hours or I will do it again for 2-4 hours.
Some people suggest 1 hour to render some suggest 8-12 hours no idea guessing its a taste difference but nothing scientific will see thank you.
