Shopping for the best Instant Pot sous vide machine? It can be confusing to pick one, since there are two sous vide machines by Instant Pot. One looks similar to the Anova Precision Cooker, or the Joule – it’s the shape of a stick and it goes in a water bath. The other looks more like a traditional Instant Pot, and it heats the water from the outside.
If you’re new to sous vide cooking, sous vide instant pots are an easy way to get your feet wet and experiment with this new kind of cookery.
Here’s a detailed look at 2020 sous vide machines by Instant Pot.
You have two options.
OPTION 1: Instant Pot Duo – with sous vide function added
For this version, Instant Pot basically added on a sous vide function to their latest Duo Crisp model.
This instant pot option is ideal for anyone who wants just one machine to do it all: no finicky attachments, no fussy cords, no hunting around for a container big enough for a sous vide bath.
The other upside is you can use it for other recipes when you’re not in a sous vide mood.

Although Instant Pot sells a sous vide attachment, called Accu Slim Sous Vide Immersion Circulator, that you can use with any of their multi-cookers you might already have, this Duo Crisp model comes with the sous vide feature built in to all the other IP features you may want in one machine.

OPTION 2: Instant Accu Slim – sous vide immersion circulator
So if you’re familiar with many of the common “stick” models on the market (Joule and Anova), then this type of setup will look familiar to you.
These stick circulators are often seen in my videos, including my latest sous vide brisket recipe.
Instant Pot’s Sous Vide Immersion Circulator attachment is a good choice if you just want to add on a machine to do sous vide.
Or if you want to sous vide and cook in an Instant Pot at the same time.
It works in much the same way as the other most popular sous vide set-ups with tools like the Anova sous vide machine or Joule sous vide machine do.
Here’s how you use the Instant Pot Slim
That’s where the attachment comes in: clip it onto your instant pot, fill the pot up with water, and you’ll have your sous vide cooker ready to go.
The Instant Accu Slim clamps securely to the 6 or 8-inch inner pot, and you can actually use it without the Instant Pot or on another container, as it covers both heating and water circulation.

Bottom line: how is Instant Pot Duo different than Slim?
Basically, the main difference is whether you want a model that has a built-in sous vide function (along with all the other Instant Pot features). Or if you just want a one-off sous vide machine by Instant Pot.
The added button on the Duo Crisp allows the pot to maintain the low temperature necessary and even includes timing functions.

Do you use a lid with the Instant Pot Duo?
Instant Pot does warn that you should not use a glass lid for the sous vide function, and instead, you should either use the stainless-steel lid pressure cooking lid or no lid at all.
Keeping the lid on will help contain the moisture. This is important for long cook times like sous vide short ribs. The water has to stay above the food level, and the lid helps contain the heat and prevents the water from evaporating.
Either way is fine, but you should be sure to pick one method and stick to it as to not interfere with the temperature regulation.
The Instant Pot Duo Crisp is best for an all-in-one multi-cooker experience, without the need for a separate sous vide machine, like previous Instant Pot models required.
Can a regular Instant Pot also sous vide?
Contrary to what some people think, you cannot use previous models of Instant Pots to sous vide to the capacity of a normal sous vide machine.
If you want a combo machine, then you need the Instant Pot Duo Crisp 11-in-1 with Sous Vide, Rice Cooker, Pressure Cooker, and a bunch of other features.
It has a “sous vide” button.
A traditional sous vide machine can’t sustain the low temperature for the amount of time needed to cook many sous vide dishes – including sous vide pulled pork.
Which sous vide Instant Pot is right for you?
Both options will produce the same results: well-cooked, super-flavorful sous vide dishes with that wonderful sous vide consistency no other cooking method can match.
Which sous vide instant pot you decide to go with depends more on your personal cooking preferences: would you rather have an attachment you can fit in a drawer, or a multi-use instant pot you can use for anything?
