Our take on the Ninja DG551 Foodi Smart XL 6-in-1 Indoor Grill

The Ninja Foodi Smart XL DG551 is a countertop indoor grill and air fryer that uses a 500°F grill grate plus cyclonic hot air to char food with grill marks. Its standout feature is the Smart Cook System: a food thermometer with four protein settings and nine doneness levels, so you can cook to rare or well-done without guessing. It also air crisps, roasts, bakes, broils and dehydrates, and a smoke-control system of splatter shield and cool-air zone keeps smoke down. It suits people who want grilled food year-round without an outdoor grill, and it competes with other indoor grills on the thermometer and the six functions rather than on size.

What reviewers say

Owners like the thermometer-guided results and the char marks from a countertop unit, and many use it as a year-round grill. Complaints center on smoke with fatty foods, the counter space it takes, and cleaning the grate and splatter shield.

What people mention
  • Thermometer accuracyPraisedOwners say the Smart Thermometer hits the doneness they pick for steak and chicken.
  • SmokeMixedThe smoke-control system helps, but fatty foods still set off smoke and sometimes a detector.
  • Grill marksPraisedReviewers say the 500°F grate leaves visible char marks and grill flavor indoors.

Questions and answers

How does the Smart Thermometer work?
You insert the probe, pick one of four proteins and a doneness level from rare to well-done, and the grill stops at your target. It removes the need to guess cooking times for steak, chicken and pork.
Does it really produce less smoke?
The splatter shield, temperature-controlled grate and cool-air zone cut smoke compared with open grilling. Fatty foods can still smoke, so use the recommended practices and ventilation.
What can it do besides grill?
It air crisps, roasts, bakes, broils and dehydrates across a wide temperature range. The included 4-qt crisper basket is for air-frying foods like fries and wings.
Can I cook from frozen?
Yes. Ninja says frozen foods go to char-grilled in under 25 minutes, which skips defrosting for items like chicken and burgers.
How much counter space does it need?
It is a large countertop appliance, so plan on keeping it out rather than storing it between uses. Measure your space before buying.
Is the grill grate dishwasher safe?
The ceramic-coated grate, crisper basket and cooking pot are removable for cleaning. Check the manual for which parts are dishwasher safe, since the coating needs care.
