Convert any oven recipe for your Ninja — using the rule printed in Ninja’s own manuals, which differs by country.
Updated · How we source our numbers
Ninja’s US manuals say reduce the temperature by 25 °F; its UK and Australian manuals say 10 °C. Neither gives a time rule — Ninja says to check food frequently.
25 °F is about 14 °C, so the UK rule is slightly gentler. Ninja’s Foodi Digital Air Fry Oven guide adds a time rule for its Air Roast setting: 25 °F lower and 30% less time.

Rounded to the nearest 5°. US Ninja basket models top out at 400 °F (AF100); above that, use the highest setting and check sooner.
