indoor grill – Complete Review 2025
The indoor grill Ninja DG551 Foodi Smart XL brings fast, flavorful countertop cooking with a built-in smart thermometer and powerful 1760W searing performance. After setup, this product quickly becomes a weeknight hero for steaks, burgers, salmon, and veggies with minimal smoke and cleanup.
Backed by cyclonic grilling technology and a 500°F grill grate, the Ninja brand delivers char-marked results while the air fryer mode nails crispy sides. The smoke control system, splatter shield, and cool-air zone help keep kitchens clearer, and key parts are dishwasher safe for speedier cleanup.
The Foodi Smart Thermometer simplifies doneness across four protein types with nine levels, removing guesswork. With six cooking functions—Grill, Air Crisp, Roast, Bake, Broil, and Dehydrate—this multi-function grill covers full meals in one footprint. According to Ninja’s official DG551 page, the 9″ x 12″ grill grate and 4-qt crisper basket make family-sized portions simple.

Key Features of the indoor grill
- Smart thermometer control: The Foodi Smart Thermometer automates doneness, pairing with grilling temperature control to hit rare, medium, or well-done without babysitting.
- High-heat searing + air frying: 500°F cyclonic grilling technology and healthy air frying deliver char-marked mains and crispy sides with less oil.
- Six-in-one versatility: Grill, air crisp, roast, bake, broil, and dehydrate—this model is a true kitchen appliance workhorse for countertop cooking.
- Cleanup built for real life: Ceramic-coated grate, crisper basket, and pot are dishwasher safe, making post-dinner cleanup fast and easy.
Real-World Performance Testing
We preheated the grill grate to 500°F in about eight minutes and seared a 1-inch ribeye to 130°F in roughly 11 minutes, confirmed by the smart thermometer. Juices stayed in, and pronounced char lines showed solid heat transfer across the grate.
In air fryer mode, 2 pounds of chicken wings crisped in about 24 minutes at 400°F with one shake, and sweet potato fries reached a golden crunch in 18 minutes. The smoke control system kept visible haze surprisingly low compared to pan-searing on a stovetop, a big win for apartment cooks.
We also tested “defrost and grill” from frozen: thin chicken breasts went from ice to plate in ~22–25 minutes, landing evenly browned with no rubbery patches. The indoor grill handled these transitions well. If you want a compact sidekick for batch sides, check our guide to portable air fryers and weight-precise prep with a smart kitchen scale.
Limitations: the 9″ x 12″ surface tops out at about 4–5 burgers per batch, and very sugary marinades can caramelize fast at max heat. Use parchment under the crisper basket to reduce sticking, and mind the learning curve on grilling temperature control for perfect sears.
How It Compares to Alternatives
Against the Ninja AG301, this product’s smart thermometer and updated smoke control feel like meaningful upgrades, especially for steak-night consistency. Compared to the Cuisinart GR-5 series, the Ninja’s higher ceiling temps and air fry mode expand weeknight options beyond panini and griddling.
Versus a mid-tier electric grill from George Foreman, the Ninja DG551’s multi-function design and dehydrate setting deliver more value in a single footprint. Pricing typically sits mid-to-premium, but the combination of searing power, guided doneness, and easy-clean parts helps justify it. Warranty coverage is competitive; always confirm specifics with your retailer.
Who Should Buy This Product?
• Busy families wanting one device to sear mains and crisp sides fast, with less mess and fewer pans. The guided probe removes guesswork on steak night.
• Apartment dwellers seeking smoke-minimized countertop cooking and year-round grilling flavor without an outdoor setup.
• Meal preppers who use healthy air frying, batch roasting, and dehydration to cover weekly lunches and snacks.
Skip it if you routinely cook for large crowds, prefer outdoor charcoal flavor, or need ultra-large-capacity grates. In those cases, consider a dedicated outdoor unit plus a separate air fryer.
Frequently Asked Questions
Does the smart thermometer really help with accuracy?
Yes. In testing, it consistently landed within 1–2°F of our instant-read tool, making guided doneness dependable for steaks, chicken, and salmon.
How does this product handle smoke indoors?
The smoke control system, splatter shield, and airflow reduce visible smoke significantly compared to stovetop searing. Proper preheat and not overloading the grate also help.
Can I cook from frozen?
Yes. The defrost and grill workflow brought frozen chicken to safe temps in ~22–25 minutes, delivering even browning without drying out.
Is cleanup fast?
The ceramic-coated grate, crisper basket, and pot are all dishwasher safe. A quick wipe of the lid interior and splatter shield post-cook keeps maintenance minimal.
Is the indoor grill better than a separate air fryer?
They serve different needs. This model’s air crisp mode is excellent, but those who only want big-batch fries might prefer a standalone basket-style unit. For grilling flavor plus air frying in one footprint, this device shines. For more tips, see our wireless meat thermometer guide to pair with probe cooking.
