Our take on the Ninja DG551 Foodi Smart XL 6-in-1 Indoor Grill With 4Qt. Air Fryer (2nd Gen)

The Ninja DG551 is a second-generation Foodi Smart XL indoor grill that also air fries, roasts, bakes, broils and dehydrates. Its 4-quart air fry basket and grill grate let it cook burgers, chicken and vegetables indoors without a stovetop, and the Smart temperature probe lets it cook to a target doneness. It suits households that want grill marks and crispy food from one countertop unit. Against single-function air fryers it is larger and more versatile; against full outdoor grills it gives up smoke and searing heat but works year-round indoors.

  • SmokeCriticisedReviewers report smoke and odor at high heat, especially with fatty foods.

Questions and answers

What can the Ninja DG551 do besides grill?
It air fries, roasts, bakes, broils and dehydrates. The grill grate and 4-quart basket swap for the different functions.
How does the Smart probe work?
You set a target doneness and the probe tracks internal temperature, then the unit stops when it is reached. It removes the need to guess cooking times for meat.
Is it big enough for a family?
The 4-quart basket suits two to four people for air frying. Large batches may need two rounds.
Will it smoke up my kitchen?
High-heat grilling of fatty foods can produce smoke and odor. Ventilation helps, and lower temperatures reduce it.
How does it compare with the first-generation Foodi Grill?
This second generation adds the Smart probe and a larger 4-quart air fry capacity. The core grill-and-air-fry design is the same.
Are the parts dishwasher safe?
The grill grate, air fry basket and other removable parts are dishwasher safe. The main unit wipes clean.
