Best answer: Most of the many components of Ninja Foodi are non-stick, but some important plastic parts need serious scrubbing to keep them clean. It is best to keep accessories on hand if you are a frequent Foodi chef.
Ceramic Coated Parts Good, Plastic Parts Poor
The major parts of Ninja Foodi are the two cookers, each for air frying and pressure cooking and cookware, including the vented "Cook & Crisp Basket." Surprisingly, whatever science magic happens in Foodi doesn't cover the lid, so a quick wipe to remove condensation is usually all it takes. The massive inner pot is ceramic coated nonstick, as is Cook & Crisp, so they are not difficult to sponge clean.
The hardest thing to clean is the feet; especially the X-shaped diffuser rack on which the curve rests. This piece is plastic, not ceramic coated, and it sits at the bottom of the pot where all the juices gather and caramelize. It is delicious on the chicken wings, but not on your stoves. I had to scrub hard or rinse between uses.
Replace parts or keep accessories on hand
Fortunately, Ninja offers individual replacement parts for literally everything on Foodi. If your diffuser is too sooty or you want an extra to change while the dirty sucks, you can buy it directly from the company for $ 9. You can replace the largest parts, including the entire base unit, to the smallest ones, such as the plastic condensation collector . If you keep metal tools and hard scrubs away from the ceramic coated items, they should remain nonstick and easy to clean for several years.
