But don't worry, we'll dive into all the nitty-gritty details in the following sections to help you decide if this grill is the right fit for your needs.
Design and Build Quality
The design and build quality of the Ninja Foodi Smart XL FG551 are quite impressive for an indoor grill. It sports a sleek, modern look that fits well in any kitchen setting. The exterior is made of durable materials, including stainless steel, which not only looks good but also adds to its longevity. It's built to withstand the heat and constant use, which is ideal for those who grill often.
One thing you'll notice right away is the compact design. Despite being an XL model, it doesn't take up too much space, making it a great option for those with limited counter space. The grill plates are generously sized, allowing you to cook multiple items at once without feeling cramped.
The control panel is user-friendly with clearly labeled buttons and a bright, easy-to-read display. It's intuitive and doesn't require a steep learning curve, which is a big plus for beginners. The lid is sturdy and well-balanced, making it easy to open and close without any awkward fumbling.
However, there are a couple of minor drawbacks. The exterior, while stylish, can show fingerprints easily, so you'll need to wipe it down regularly to keep it looking pristine. Additionally, some users might find the grill a bit on the heavy side, which could be a concern if you plan to move it around frequently.
Overall, the Ninja Foodi Smart XL FG551 offers a solid build and thoughtful design, making it a reliable choice for grilling enthusiasts. It combines functionality with style, ensuring it not only performs well but also looks good doing it.

Key Features and Technology
The Ninja Foodi Smart XL FG551 is packed with some pretty nifty features and tech that make it stand out in the electric barbecue scene. At the core of its technology is the Smart Cook System, which takes the guesswork out of grilling. This system uses a digital probe to monitor the internal temperature of your food, ensuring precision cooking every time. You can say goodbye to overcooked or undercooked meals! Another cool feature is the Foodi Smart Probe. This probe continuously monitors the internal temperature of your food, providing you with real-time updates. You can select from a range of doneness levels, like rare to well done, and the grill will handle the rest. It’s like having a personal chef without the hefty price tag.
Multifunctional Cooking
This grill isn't just for steaks and burgers. It offers a variety of cooking modes, including grilling, air frying, baking, roasting, dehydrating, and broiling. This versatility makes it a great option for anyone who loves experimenting in the kitchen. However, with all these functions, it might be a bit overwhelming for those who prefer simpler options. The Cyclonic Grilling Technology is another highlight. It circulates air around the food, ensuring even cooking and that sought-after char-grilled finish. This feature is perfect for achieving those crispy outsides and juicy insides that everyone loves.
User-Friendly Interface
The control panel is easy to navigate, with clear buttons and an intuitive layout. The digital display is bright and readable, even in lower light conditions. However, some users might find the number of options a bit much at first glance. But once you get the hang of it, it’s smooth sailing. In terms of technology, the Ninja Foodi Smart XL FG551 is a powerhouse, though its extensive features might be a bit daunting for novices. Yet, for those willing to explore, it offers a wealth of possibilities to elevate your cooking game.

Performance and Cooking Experience
The performance and cooking experience with the Ninja Foodi Smart XL FG551 is quite impressive. This indoor grill is engineered to deliver consistent results, making it a favorite for both beginners and seasoned cooks.
Grilling Power and Precision
With its robust power, this grill heats up swiftly and maintains a steady temperature throughout the cooking process. The integrated Smart Cook System is a game-changer, allowing you to achieve the perfect doneness every time. Whether you prefer your steak rare or well-done, the built-in thermometer provides accurate readings, taking the guesswork out of cooking.
Versatility in Cooking
One of the highlights is its ability to handle a variety of foods. From juicy burgers to grilled veggies, the Ninja Foodi Smart XL handles it all with ease.

Potential Drawbacks
However, it’s not all rosy. Some users might find the preheat time a bit longer compared to other electric grills. Additionally, while it offers a great grilling experience, it might not fully replicate the smoky flavor that some charcoal grill enthusiasts crave.
Overall, if you're looking for a reliable and versatile indoor grill, the Ninja Foodi Smart XL FG551 offers an enjoyable cooking experience with few downsides. Its combination of technology and design makes it a worthwhile investment for most home cooks.

The Smart Cook System with the integrated thermometer is a nifty feature, especially for those who aren't quite sure when their meat is perfectly done.
Cleaning this electric grill is also relatively hassle-free. Most of the parts, like the grill grate, crisper basket, and cooking pot, are dishwasher safe, which is a huge time-saver. The non-stick surfaces make it easy to wipe away grease and food residue with minimal effort.
However, the grill can be a bit bulky, so if you have limited counter space, storing it might be a challenge. Also, while the non-stick surfaces are great, you might still need to give the grill plate a bit of extra cleaning if you’ve been cooking something particularly sticky or greasy.
Overall, the Ninja Foodi Smart XL FG551 offers a convenient cooking experience with minimal fuss when it comes to cleaning. Just make sure you have a good spot to store it when it's not in use!

Competitor Comparison
When you're in the market for an electric barbecue, it's helpful to see how the Ninja Foodi Smart XL FG551 stacks up against some of its main competitors. Let's dive in and see what sets it apart, and where it might fall short.
Versus George Foreman Indoor/Outdoor Grill
The George Foreman Indoor/Outdoor Grill is a popular choice for those looking for versatility in their grilling. It offers a large cooking surface and the ability to grill both indoors and outdoors. However, it doesn't come with the smart technology and precise temperature controls that the Ninja Foodi offers. If you're after smart cooking features and precise doneness levels, the Ninja might be more up your alley. On the flip side, the George Foreman grill is often praised for its simpler design and ease of use, making it a strong contender for those who prefer straightforward grilling without the bells and whistles.
Versus Breville Smart Grill
The Breville Smart Grill is another competitor that brings some smart technology to the table. It offers features like adjustable plate height and temperature sensors for even cooking. However, the Ninja Foodi Smart XL FG551 stands out with its built-in smart thermometer, which takes the guesswork out of achieving the perfect doneness. While the Breville is known for its high-quality build and sleek design, it might not offer the same level of cooking precision for meats as the Ninja.
Versus Philips Smokeless Indoor Grill
If you're concerned about smoke levels, the Philips Smokeless Indoor Grill is a strong contender with its advanced infrared technology that minimizes smoke. It's great for indoor grilling without setting off your smoke alarm. However, it doesn't match the Ninja's capacity and versatility. The Ninja can grill, air fry, and roast, making it a more multifunctional appliance in your kitchen arsenal. The Philips grill is a bit more limited in its cooking options but excels in providing a smokeless experience.
Price Comparisons
When it comes to pricing, the Ninja Foodi Smart XL FG551 sits in the mid to high range, depending on where you purchase it. The George Foreman tends to be more budget-friendly, while the Breville and Philips models are often priced similarly to the Ninja, reflecting their advanced features and build quality. It's worth considering what features are most important to you and how much you're willing to spend. Overall, the Ninja Foodi Smart XL FG551 holds its own against these competitors with its smart cooking features and versatility. However, if you're looking for simplicity or smokeless grilling, the other options might be worth a look.

Conclusion
Wrapping up, the Ninja Foodi Smart XL FG551 is a solid choice for anyone looking to elevate their indoor grilling experience with a versatile electric grill. Its smart technology and 6-in-1 cooking options make it a standout in its category. This grill doesn't just cook; it cooks with precision, thanks to its integrated smart thermometer and intuitive settings.
The build quality is impressive, offering a sturdy and durable design that feels like it can withstand the test of time. However, it's worth noting that its size might not suit those with limited counter space. If space is a concern, you might want to measure your available area before purchasing. In terms of performance, it delivers consistent and delicious results, whether you're grilling steaks, roasting veggies, or even baking. The ability to achieve that perfect sear with an electric grill is a definite plus.
Cleaning this device is relatively straightforward, especially with its non-stick grill plates and dishwasher-safe parts. Yet, some users may find the cleaning process a bit more involved if they're not familiar with disassembling kitchen gadgets. If you're comparing options, this model stands out for its smart features and cooking versatility. While it might come with a higher price tag than some simpler models, the investment could be worthwhile for those who value convenience and precision in their cooking.
In summary, the Ninja Foodi Smart XL FG551 offers a blend of innovation and ease of use, making it a great addition to any kitchen for those who love grilling without the fuss of traditional setups. Just ensure it meets your space and budget needs before making the final decision.
