Ninja Foodi MAX Health Grill AG551UK
Grey/Silver
Editorial review Reviewed 18 October 2026 How we assess products
The AG551UK is here for buyers who want grilling as much as air frying. Its digital probe and grill plate make a stronger case for meat and fish than a basic basket machine. Swap to the crisper basket for air frying, with roasting, baking, reheating and dehydrating also available. This is one chamber, so it will not independently grill a steak and air fry chips at the same time. Preheating and cleaning the splatter guard are part of the routine, and the heavy body needs lid clearance. The removable cooking parts simplify washing, but the probe and powered body need hand-cleaning. Availability is now more dependent on marketplace sellers; compare current probe-equipped grills carefully rather than paying a large premium for this older model.
