The Ninja DG551 and IG651 are two of the most popular appliances in the Ninja lineup, each catering to distinct kitchen needs. If you are wondering which Ninja appliance to buy, this detailed guide breaks down their features, specifications, and performance to help you make an informed decision.
Main Difference Between Ninja DG551 and IG651 Indoor grills
The primary difference lies in their functionality and design. The Ninja DG551 is a precision dehydrator, ideal for slow cooking and drying fruits, vegetables, and meats at controlled temperatures. The Ninja IG651, on the other hand, is a multifunctional griddle and roasting appliance, designed for grilling, roasting, baking, and searing with versatility in mind.
Design and Build Quality
The Ninja DG551 indoor grill is sleek and compact, with stackable trays, a digital thermometer, and precise temperature controls that prevent overheating. Its design prioritizes low-temperature cooking and efficient airflow for even drying.
The Ninja IG651 indoor grill is larger and robust, featuring adjustable roasting racks, stainless steel lifters, and a spacious cooking surface. Its design emphasizes versatility, durability, and multi-function daily use beyond dehydration.
Functionality and Features
The DG551 indoor grill focuses on precise temperature control between 105°F and 160°F. It’s perfect for:
- Dried fruits (apples, bananas, mangoes)
- Jerky and cured meats
- Herbs and spices
Additional features include quiet operation, digital timers, and easy-to-clean stackable trays.
The IG651 indoor grill is multifunctional and supports six cooking modes: Grill, Roast, Bake, Air Fry, Dehydrate, and Griddle. It reaches temperatures up to 450°F, suitable for:
- Quick searing steaks and chicken
- Grilled sandwiches and pancakes
- Roasting vegetables or small meats
Advanced features include multiple heat zones, non-stick surfaces, and removable racks for easy cleaning.
Cooking Performance
The DG551 excels at low-temperature, slow dehydration. For example, it produces evenly dried apple chips in 8 hours at 135°F and beef jerky consistently without hotspots.
The IG651 is ideal for fast cooking. It can reach a 450°F searing temperature in under 5 minutes and cook a 1-inch steak to medium-rare, making it suitable for daily versatile cooking.
