Ninja AG301 Vs FG551

In-depth Comparison: Ninja FG551 Vs AG301 – The Best Indoor Grill

The main difference between Ninja FG551 Vs AG301 lies in the sophistication of their features. While both models share some common functionalities, the FG551 stands out with its Smart Cook System and the Foodi Smart Thermometer. These features elevate its versatility and precision, offering a richer and more tailored cooking experience.

1. Smart Cook System: FG551 Advantage

Present only in the Ninja FG551, the Smart Cook System is designed to optimize cooking times and temperatures. This system includes four smart protein settings and nine customizable doneness levels, effectively eradicating the guesswork from your cooking process. This feature provides the user with the advantage of precision, ensuring every meal is cooked to the desired doneness. Conversely, the AG301 does not have this feature and thus requires manual temperature and time adjustments.

2. Foodi Smart Thermometer: The Edge of FG551

Another distinguishing factor of the Ninja FG551 is its dual-sensor Foodi Smart Thermometer. This thermometer continuously monitors the temperature in two places, giving you more accurate results. This level of precision is pivotal in avoiding overcooked or undercooked meals. On the other hand, the Ninja AG301, though an impressive model, lacks this feature.

3. Grill Grate Size: Ninja FG551 Takes the Lead

In terms of capacity, the Ninja FG551 offers a larger grilling space with a 9″ x 12″ grill grate, enabling you to grill up to 6 steaks or 24 hot dogs simultaneously. This feature is great for larger families or hosting dinner parties. In contrast, the Ninja AG301 comes with a 10″ x 10″ grill grate, slightly smaller but still ample for everyday cooking needs.

4. Number of Cooking Functions: FG551 Has More

The Ninja FG551 is equipped with six cooking functions: Grill, Air Crisp, Roast, Bake, Broil, and Dehydrate. These functionalities make it a more versatile appliance that can handle a broad range of recipes. The Ninja AG301, on the other hand, boasts five cooking functions, lacking the Broil feature present in the FG551.

The Ninja FG551 serves as an upgraded model in the Ninja Foodi grill line, boasting enhanced features and increased capacity that clearly distinguish it in the Ninja FG551 Vs AG301 debate. With a key feature being the Smart Cook System, this grill is a dream for those who appreciate precision in their culinary adventures. The Foodi Smart Thermometer is another standout addition, enabling perfect doneness from rare to well-done and eliminating guesswork.

The FG551 goes beyond just grilling, providing six versatile cooking functions including Grill, Air Crisp, Roast, Bake, Broil, and Dehydrate.

Much like the AG301, the FG551 uses Cyclonic Grilling Technology and offers the “Forget About Defrosting” feature. However, the FG551 takes it a notch higher with the introduction of a Smoke Control System. This temperature-controlled grill grate, splatter shield, and cool-air zone combine to reduce smoke, keeping your kitchen clean and fresh. This unique feature gives the FG551 an edge in the Ninja FG551 Vs AG301 comparison.

Despite the increased functionality and size, the FG551 maintains an accessible design with dishwasher-safe components for easy clean-up. It’s worth noting that while the FG551 carries a higher price tag in the Ninja FG551 Vs AG301 comparison, it offers significant upgrades and improvements that justify the cost.
