Instant Pot Omni Plus Air Fryer completes the brand’s line of compact convection ovens. It’s comparable to the Ninja Foodi XL Pro Air Oven, except for the rotisserie function, which is its ultimate asset.

Because of the narrow space, it can only fit a 4 lbs chicken. But if you think of it, you can also make porchetta, shawarma, or kebabs utilizing the same space. The rotisserie function is indeed a game-changer in the air frying niche.

The Instant Omni Plus is an XL toaster oven with 19 quarts (18L) cooking capacity. You can fit a 12-inch pizza in it or toast six slices of bread in one go. In short, it’s a massive multi-cooker.

The bad news is you need to have enough space for a 16-inch kitchen appliance. If you want something smaller, you might want to check the Instant Pot Vortex Plus. It’s also has a rotisserie feature.

I also have to mention that the Instant Omni Pro Toaster Oven has already superseded this model. It’s more of a smarter version with a built-in probe thermometer.

Now let’s get back to the Instant Omni Plus Air Fryer and explore its benefits and drawbacks.


  • Elegant design
  • Easy to use touchscreen controls
  • Double layer glass for proper heat insulation
  • Cooks evenly (EvenCrisp and Golden Quartz Infrared Heating Technology)
  • XL capacity perfect for a family or gatherings
  • Wide temperature range
  • 10 core cooking functions
  • 5 adjustable toasting levels
  • Progress indicator
  • BPA, PFOA, PTFE Free
  • Dishwasher safe parts
  • 1-year warranty


  • Excellent product for a premium price tag
  • A bit loud
  • While it’s smaller than the 26L version, it still needs an adequate space on your countertop
  • Door construction could have been better
  • It gets pretty hot
  • Needs additional space above and around the oven, so it would take up sufficient area.

What can you cook with the Instant Pot Omni Plus Air Fryer?

The Omni Plus Instant Pot has 10-in-1 cooking functions — air fry, roast, bake, broil, reheat, toast, convection, warm, dehydrate, and rotisserie.

Here’s a more visual representation:

Let’s jump right in:


The Instant Pot Omni Plus Air Fryer has 5 personalized toasting levels that suit your toast darkness preference. You can fit 6 slices of bread or 6 bagel halves at a time. You’ll save cooking time as you can toast multiple pieces at once.

Air Fry, Bake, and Roast

This air fryer uses convection cooking to bake, roast, and air fry your meals. You can bake a 12-inch pizza using the oven rack. Plus, you can cook grease-less, crispy, and juicy chicken wings or jalapeño poppers with the air fryer basket. You can also create delicious dishes with reduced calories from oil.


Imagine the bubbling melted cheese on top of your baked potatoes. The broil function of the Omni Plus Air Fryer with the direct top-down heat melts the cheese and caramelizes fruits and vegetables.

Warm and Reheat 

Let’s say you’re done cooking but not ready to serve? The warm function of this air fryer keeps your food warm without the worry of overcooking. Or if you want to reheat food without compromising the texture and flavor? The reheat function will help you achieve crunchy and tender leftovers in minutes.


The dehydrate function will help you make homemade veggie and fruit crisps, jerkies, or fruit leathers. The default time is 8 hours, but you can set the time from 30 minutes to 72 hours.


This air fryer comes with rotisserie spit and forks essential for roasting whole 4lb chicken, leg of lamb, or kebobs. The EvenCrisp technology of Instant Pot yields a tender, juicy and crispy dish with a small amount of oil, which means no need for added calories from fat.

Pro Tip: Before preheating the Omni Plus Toaster Oven, insert the rotisserie spit and food into the cooking chamber first.

You can find cooking times and temperature recommendations in the manual as a guide, but you can modify the presets to adjust to your liking.

Is the Instant Pot Omni Plus Toaster Oven easy to use?

Yes, the digital program bar and the rotary knob make this air 18L Omni Plus Toaster Oven user-friendly. 

What makes me say so?

With a touch of a button, you can set the time and temperature or turn the dial to switch through functions. The use of text in the control panel is straightforward. This way, you do not need to guess what feature you’re setting your air fryer.

As an oven-type air fryer, you would not think it uses 50% less energy. 

But how? 

You’ll need less time to warm up the oven as it preheats in seconds.

And the Good news?

The brand claims to help you use 95% less oil than deep frying.

How to Clean the Omni Plus Instant Pot Air Fryer?

Clean-up is effortless. You can easily wipe the Omni Plus parts with a warm and soapy sponge. Most parts/accessories, even the rotisserie spit, forks, and screws, are dishwasher safe. Remember to put the small pieces in washable mesh bags to keep them intact. 

You can clean the air fryer basket with a bristled brush and wipe down the exterior with a dry cloth.

Pro tip: Ensure that grease drippings and food debris are removed from the crumb tray to prevent smoking. Line with parchment paper or spray with non-stick cooking spray for easier cleaning.

Don’t take my word for it, here’s a short video demonstration from Aaron.

The Instant Omni Plus is an all-in-one high-performance toaster and air fryer with 10-in-1 cooking functions: air fry, broil, bake, roast, dehydrate, reheat, rotisserie, toast, warm, convection. The cooking temperature can be adjusted from 170 to 450 °F (76 to 232 °C). The extra-large, 18L (19 Quarts) capacity can fit 6 slices of bread, a 12-inch pizza, or 4-lbs chicken at a time.

What makes it better?

First off, this oven has a large capacity of 18L (19 Quarts), making cooking more efficient without taking up so much space on your countertop. More importantly, the Instant Omni Plus Air Fryer’s stylish design and versatile functions.

By the way, the Instant Pot Omni Plus 11-in-1 toaster oven, an older version of this air fryer, has a 26L (27 Quarts) capacity. Even if the 11-in-1 toaster oven has a bigger capacity, both products can fit 6 slices of bread at a time.

Now, going back to the newer Instant Omni Plus:

Compared with the basket air fryers, this oven-type air fryer has a progress display and a double-layer glass door that lets you see each cooking phase. 

The air fryer also has a Golden Quartz technology which delivers even heating.
