Top 3-Quart Instant Pots

#1 Instant Pot Duo Plus Mini – Best Overall

Best Small Instant Pot, IP Duo Plus

The Instant Pot Duo Plus line is the upgraded version of the classic Duo Series, with a safer pressure release, more cooking functions, and a more refined look.

Instant Pot Duo Plus Mini or Duo Plus 30, is the 3-qt version of the best-selling (Duo Plus) pressure cooker.

Why is it the Best Small Instant Pot?

Compared to other compact pressure cookers from the kitchen appliance manufacturer, the Duo Plus 30 is as capable as its 6 or 8-qt sibling. No feature was spared in this compact configuration. Whatever the size you’re getting, you’ll have access to 15 smart programs.

You won’t have that advantage with the Duo Mini nor the Ultra Mini. The brand stripped down two automatic programs from these smaller variants.

The Instant Pot Duo Plus Mini has nine core cooking functions—pressure cooker, slow cooker, rice cooker, yogurt maker, steamer, sauté/searing pan, sous vide, sterilizer, and food warmer. Hence, it’s also called the 9-in-1 Instant Pot.

#2 Instant Pot Duo Mini – Best Cheap

Instant Pot Duo Mini, Stainless Steel/Black

The 3-quart Instant Pot Duo Mini or the IP Duo 30 is the cheapest among the three compact pressure cookers. I have to note that this model is a classic, but it’s been retrofitted with the newest features since it was released almost a decade ago.

Well, except for the upgraded vent release and sous-vide function.

Despite not having those features, Instapot Duo Mini is still a skillful multicooker. You can still take advantage of its seven main cooking functions—pressure cook, slow cook, sauté, steam, cook rice, yogurt, and food warmer.

IMHO, those functions are pretty adequate if you’re just starting out. Having sous-vide program is nice, but it’s not as necessary as pressure and slow cooking.

Here’s a demo video of the IP Duo Mini.

#3 Instant Pot Ultra Mini – Best Premium

Instant Pot Ultra Mini, Silver

Instant Pot Ultra Mini or simply the IP Ultra 30 could have been on top of this best small Instapot roundup if it’s still in stock. The last time I checked, it’s no longer available at Amazon or even the Instant Brands shop.

Hopefully, the company will restock it or release a newer version of this portable digital pressure cooker.

The IP Ultra collection is the predecessor of the Instant Pot Max, which comes with a touch screen interface and a convenient turn dial. It’s a more elegant and user-friendly solution than the traditional buttons.

One fantastic feature it has is the Ultra Mode. That’s where you can access its sous vide feature by dialing in the proper settings. Technically, you can program as many cooking presets as you want with this compact pressure cooker.

But the sad thing is, IP Ultra Mini is no longer available.

Cons of Getting a Mini Instant Pot

Despite all those positive things, you need to know the disadvantage of having a small Instant Pot. Apart from not having most of the automatic cooking programs, 3-quart Instant Pots are not compatible with the brand’s air fryer accessory.

Thankfully, that’s the only drawback that I can think of.

Despite its size, indeed, 3-quart Instapots are jack of all trades.

Over To You?

In our opinion, every household should own a multicooker. The pressure cooking function alone will pay for itself in no time. Instead of waiting for hours, your can tenderize your meat in 10 to 20 minutes.

Now, if your kitchen doesn’t have much space for a massive kitchen appliance, a 3-quart Instant Pot would be your best option.

With that said, I’m leaving you with our best small Instant PotIP Duo Plus Mini.

Dimension-wise, the smallest Instant Pot is the IP Duo Mini, followed by Instapot Ultra Mini, and lastly Instapot Duo Plus Mini. The size differences are subtle, so mainly, they all have a minor footprint than other pressure cookers.
