Ninja Foodi SmartLid OL550UK
6L pressure cooker, air fryer and combi-steam cooker
Editorial review Reviewed 25 October 2026 How we assess products
The Ninja Foodi SmartLid OL550UK is the choice when pressure cooking, air frying and combined steam cooking will all get used. One hinged SmartLid switches between modes, while Steam Air Fry and Steam Bake combine moist heat with browning. Pressure cooking and steaming also perform well, and the clear display and recipe guide help with learning the settings. A 6L pot, 3.7L Cook & Crisp basket and reversible rack are included. Those capacities serve different jobs; do not treat the pot volume as the amount of food the air-frying basket can hold. The cooker is bulky and needs room above its lid and around the steam outlet. Follow the cleaning instructions and protect the non-stick parts with suitable utensils. A simpler pressure cooker is better value if you will rarely use crisping, while the Instant Pot Duo Crisp Ultimate Lid offers a lower-cost pressure-and-air-fry alternative without the combined steam settings.
