Difference Between Ninja Fg551 Vs Ag301

Outdoor grilling and weather go hand in hand but with extreme weather changes around the globe indoor grilling has become a norm and indoor grills are taking their rightful place in every household.  The Ninja Fg and Ag series of indoor grills offer some premium class smokeless indoor grills for a complete grilling experience without messy startup and cleanup afterwards. Grill without sacrificing the convenience of your home is what Ninja is all about. Let’s explore the key difference between Ninja Fg551 vs Ag301 indoor grills.

Appearance & Design

When it comes to indoor grill design, there are a few things to consider. First, you want to make sure that the grill is large enough to cook enough food comfortably. Second, you’ll want to choose a grill with a design that will fit in well with your kitchen décor. And you’d want a grill that can easily be accommodated in the available counter space.

Ninja Fg551 features a boxy design with sleek & eye-catching appearance. Its stainless steel and black exterior fits right in and make it look better enough to be kept on the counter permanently. Even if you have a small counter, the Ninja Fg551 indoor grill does job of several other appliances to so you can replace multiple cooking appliances with one. Fair enough?

The Fg551 indoor grill is fairly large measuring 16x17x11 Inches and weighs about 22 pound which is not the most portable grill out there but given the cooking features, functions and space it has to offer, it is justified. The large hinged dome can easily be lifted with a cool touch handle and it also houses the heating element, fan and air inlet vent.

It features a touchscreen digital display on the front side to choose the cooking program, temperature and cooking time for required doneness. The control panel is intuitive and extremely easy to follow whether or not you have used an advanced indoor grill before.

On the contrary, Ninja Ag301 measures 15x15x11 Inches in dimensions and weighs about 15 pound which is slightly light in comparison to Ninja Fg551 Foodi grill. On top of the dome, there is an air inlet vent and the air outlet vent is at the back so avoid placing the grill close to the wall and under a cabinet. Ag301 indoor grill has a touchscreen control panel which is clear and straightforward to understand. Overall, the two Ninja grills are nothing short of awesomeness.

Cooking Capacity

Grills are meant to be large enough to cook large batches of meals for entire family.

Ninja Fg551 does offer more grilling surface while Ninja Ag301 comes with bigger 6 Quart cooking pot. Meanwhile, the crisping plate capacity remains the same with both indoor grills.

Ninja Fg551 lets you prepare 6 steaks, 24 hot dogs, mains and sides at the same time which is more suitable for large gatherings or backyard family parties.

Ninja Ag301 has a cooking capacity of 4 steaks, 5 burgers, 2.5 pounds French fries, and 2.5-pound chicken roast. Ninja Fg551 is clearly bigger with more grilling space but Ag301 has bigger cooking pot for baking, dehydrating and roasting.

No matter how many times you have tried a recipe, cooking steaks is a new battle every time. With Ninja Fg551 and Ag301, pulling off perfectly cooked steak with push of a button is pretty exciting. On the other hand, although we have tried and tested a number of appliances in Something-shop kitchen we always are skeptical of how a product will deliver.

We tested both Ninja Fg551 and Ag301 Foodi indoor grill and tried grass fed steak, burgers, fries, and hot dogs of course. It hardly took 5 minutes to preheat and to our surprise both grills delivered shockingly amazing results.

The steaks were juicy on the inside and had that perfect smokey texture that a traditional grill delivers. French fries tested the air frying capabilities of both grills and the results were fantastic. It was hardly taking 10-15 minutes on everything we tried means Ninja grills let you cook with a flash.

On the other hand, Ninja Ag301 Foodi indoor grill also has 4.8/5 star rating but a whopping 21 thousand reviews from around the world out of which 96% are happy users.

One reason is of course more cooking functions, smart temperature probe, and more cooking space however, price seems to be another factor because not everyone can spare two hundred bucks.
