Ninja DG551 and FG551 Foodi Smart XL Grills: Pros and Cons

The main difference between the Ninja DG551 and FG551 lies primarily in their design and the generation to which they belong. The DG551 is a 2nd Generation Foodi model with an updated, sleek design. In contrast, the FG551 is a 1st Generation model, sticking more closely to the traditional Ninja Foodi design. However, both models continue to uphold Ninja’s reputation for multifunctionality and high-quality cooking results.

Design & Generation

As mentioned earlier, the most noticeable difference when comparing Ninja DG551 vs FG551 is their design and generation. The Ninja DG551, with its updated and sleek design, belongs to the 2nd generation of Ninja Foodi appliances. This new design might appeal to users who appreciate a more contemporary aesthetic in their kitchen gadgets. In contrast, the Ninja FG551 is from the 1st generation of Ninja Foodi models, adhering to the traditional Foodi design. While some might perceive it as less modern compared to the DG551, many users appreciate the tried-and-true design that has already proven itself in numerous kitchens.


The Ninja DG551 operates at 825 watts, while the FG551 model functions at a higher wattage, up to 1760 watts. The higher wattage in the FG551 model could translate to more power and potentially faster cooking times, although this might also reflect in higher energy consumption.

Special Features

When it comes to special features, the DG551 distinguishes itself with its XL Capacity and dishwasher-safe parts. This feature might be especially attractive to large families or people who frequently cook for gatherings, as it allows for preparing larger quantities of food in one go. Furthermore, the dishwasher-safe parts simplify the cleaning process, making it a convenient choice for those with busy lifestyles.

On the other hand, the FG551, while sharing the DG551’s 6-in-1 functionality, highlights its programmable feature. This could be a game-changer for those who prefer more control and customization over their cooking process.

Material & Weight

Another significant difference between Ninja DG551 and FG551 is the material they’re made from and their weight. The DG551 is made from ceramic and weighs around 25 pounds, while the FG551, made of stainless steel, weighs slightly less at approximately 22.44 pounds. This difference might influence your decision if you prefer lighter appliances or have specific material preferences for durability and aesthetics.

Components Included

Both models come with a variety of components to assist in cooking and cleaning. However, the DG551 includes additional components like a Splatter Shield, which helps reduce smoke and keep your kitchen clean. This could be a deciding factor if you are concerned about smoke and mess during grilling.

In this comprehensive breakdown of the DG551 vs FG551, we’ve explored the key differences between these two excellent Ninja Foodi models. Each has its unique strengths and distinct features, and the final decision will largely depend on your personal needs, aesthetic preference, and lifestyle. Whether you choose the Ninja DG551 or FG551, you’re investing in a high-quality, versatile kitchen appliance that will elevate your home cooking experience.
