Ninja 9-in-1 8-Qt Pressure Cooker Foodi OP401 Review

Ninja OP401 Foodi 9-in-1 PressureProduct Overview

This multi-function cooker from Ninja adds in a crisping lid that turns the cooker from a wet pressure cooker to a dry air fryer and broiler. With this lid, you not only get the traditional functions of a 7-in-1 cooker like the Instant Pot, but you also add in a dehydrator and air fryer as well. This lets you add crispiness to any food you cook. If you make a chicken in the Foodi, you can then spend an extra ten minutes crisping the skin for more appeal and better flavor. The dehydrator with the optional rack let you make dehydrated fruit chips or kale and other veggies easily.

Final Points

You wouldn’t think that packing two more functions into a multi-cooker would make much difference, but oh does it ever. Crispy French fries and putting a toasted topping on mac and cheese makes a subtle but important difference. However, that added functionality does come at a fairly hefty cost, so try to score this one on sale if you can.
