The Ninja Foodi OL501 pressure cooks, steam-crisps and air fries in one 6.5-qt pot using a single SmartLid. This page is based on manufacturer-published specifications and manuals plus aggregated owner reviews; we did not test the products ourselves.
Our verdict
If you want a pressure cooker that can also crisp, the OL501 replaces two appliances. It is large and heavy (24.03 lb), so if you only need pressure cooking, the Instant Pot Duo is smaller, lighter and has a stainless pot.
