The Ninja FlexFlame outdoor cooking system positions itself as a versatile alternative to traditional grilling methods, appealing to those who appreciate both the efficiency of propane and the specialized capabilities of various cooking appliances. This in-depth analysis probes the FlexFlame's promise of multi-functionality, examining its capacity to perform beyond simple grilling, including smoking, griddling, and baking. The goal is to ascertain if this single unit can truly master multiple cooking techniques or if its broad ambition compromises specific functionalities.
To thoroughly assess the Ninja FlexFlame's capabilities, a series of comprehensive tests were conducted over an extended period. These evaluations scrutinized every aspect of its design and performance, including the initial setup and overall user-friendliness, its speed in reaching optimal grilling temperatures, and its effectiveness in cooking a variety of foods such as corn, burgers, and kielbasa on the grill grates. The review also covered the efficiency of its griddle for searing smash burgers, its ability to bake a pepperoni pizza using the dedicated stone, and the quality of its smoking function for cold-smoked deviled eggs, along with an assessment of the included pellets. This systematic approach provided a holistic view of the FlexFlame's multi-faceted performance.
Unlike conventional gas grills that rely solely on propane and a simple igniter, the Ninja FlexFlame introduces an electronic component, necessitating an electrical connection. This hybrid power requirement means the unit must be plugged in, often requiring an extension cord due to its short power cable. The ignition process, which involves pushing and twisting a dial, proved to be somewhat temperamental, often requiring several attempts to engage the burners. While this might be a minor inconvenience, it raises concerns about the longevity and reliability of integrating electronics into an outdoor appliance. However, a notable advantage is the clear, bright digital display for temperature, offering precise control beyond predefined settings, which enhances the cooking experience.
A key feature contributing to the Ninja FlexFlame's performance is its integrated fan, similar to those found in pellet grills. This fan creates a consistent heat distribution when the lid is closed, significantly reducing preheating times—the unit reached 500°F in just over six minutes. While this convection system ensures thorough and even cooking, facilitating impressive char marks on items like hot dogs and sausages, it operates with a considerable amount of noise, akin to a jet engine during takeoff. Despite the noise, the grill consistently delivered excellent grilling results, affirming its capability as a robust propane grill.
Beyond its primary grilling function, the Ninja FlexFlame includes several other modes. The griddle attachment, though compact, adeptly seared smash burgers, producing a desirable crispy texture. The pizza stone also performed commendably, baking pizzas with a satisfyingly crisp crust and achieving quick results. However, the smoking feature fell short of expectations. The small hopper capacity for pellets combined with an uncontrolled combustion, where pellets rapidly ignited rather than smoldered, resulted in an acrid, burnt-rubber aroma and imparted an overly bitter, smoky flavor to the food. This highlights a significant area for improvement in the FlexFlame's multi-functional design.
The Ninja FlexFlame stands out as a competent gas grill, characterized by its rapid heating, propelled by a potent, albeit loud, convection fan, and its ability to achieve excellent searing without scorching food. Despite a somewhat temperamental ignition mechanism, its clear digital temperature display is a valuable asset. Most of its supplementary features, such as the griddle and pizza stone, function adequately, demonstrating versatility, though they don't offer groundbreaking performance that couldn't be achieved with standard grill accessories. The smoking function, however, proved problematic, failing to deliver controlled smoking and instead leading to excessive combustion. While the FlexFlame is a solid grilling unit, its premium price point, coupled with the merely satisfactory performance of its additional features and the notable shortcomings in its smoking capability, suggests that consumers prioritizing dedicated grilling might find better value in more conventional and often less expensive alternatives like a Weber.
The Ninja FlexFlame, fundamentally a grill, excels in its core function. Despite an initial setup that can be cumbersome and a starting process that occasionally requires persistence, once operational, it heats up with remarkable speed. Its powerful convection fan ensures rapid and even heat distribution, leading to quick cooking times and excellent searing on a variety of foods, from sausages to burgers, resulting in perfectly charred exteriors and moist interiors. This fan also contributes to the efficient baking of pizzas, yielding puffy edges and a crisp base. Furthermore, while the smoking pellets presented challenges, they did impart a distinct, smoky flavor to cold-smoked deviled eggs, showcasing its potential in this area despite operational flaws. Overall, the grill's primary capabilities and its passable secondary functions underscore its utility as a versatile outdoor cooking tool.
Assembling the grill proved to be a time-consuming task, involving numerous components and a multitude of screws. A significant design flaw is the necessity of an electrical connection for operation; the short seven-inch cord frequently requires an extension, limiting placement options and introducing vulnerability to electronic malfunctions. The ignition dial, which also activates the electric interface, is inconsistent, sometimes demanding multiple attempts to start the burners. Beyond these setup and operational quirks, the FlexFlame's auxiliary features, particularly the smoker, were less impressive. The smoker's pellets ignited uncontrollably, producing flames rather than a steady smoke, and the grill's fan generates a loud, airplane-like noise during operation. These factors detract from the overall user experience and question the practical utility of its multi-functionality.
The Ninja FlexFlame features a generous cooking area of 424 square inches, powered by three burners that collectively deliver 37,000 BTUs. Designed for outdoor mobility, it includes two wheels for easy relocation and two convenient side tables for food preparation and storage. Ninja backs this unit with a substantial 10-year warranty, reflecting confidence in its durability. However, it's important to note that the basic package does not include a pizza stone or griddle, which are typically advertised features but require separate purchase. The grill is also exclusively compatible with propane and does not offer a natural gas option, which might be a consideration for some users.
