Ninja Flexflame Vs Weber Searwood Grill & Smoker: The Ultimate Outdoor Cookout Showdown

The modern backyard deck has transformed from a simple spot for a basic charcoal kettle into a high-tech outdoor kitchen. Over the last few seasons, manufacturers have pushed past traditional fuel boundaries, engineering hybrid systems that promise to do everything from low-and-slow smoking to high-heat searing and even artisanal baking. The goal is simple: eliminate the need for a separate smoker, griddle, and gas grill by packing all those capabilities into a single footprint.

Lately, my outdoor cooking has been dominated by two heavy-hitting machines that approach this multi-fuel challenge from entirely different engineering angles: the Ninja Flexflame (Model PG301GN) and the Weber Searwood (Searwood 600).

After spending months putting both platforms through their paces – firing them up in freezing morning air, running overnight brisket cooks, and blasting them to maximum heat for quick weeknight steaks – I have mapped out exactly how these competing systems perform. This isn’t a speculative look at a spec sheet. It is a practical, first-hand look at an electric-gas hybrid cooking system facing off against a digitally optimized, direct-flame wood pellet smoker. Let’s dive into how they actually compare when the smoke clears.

Key Difference: Ninja Flexflame Vs Weber Searwood Grill & Smoker

The core operational divide between the Ninja Flexflame and the Weber Searwood comes down to how they generate heat and distribute flavor. The Ninja Flexflame is a unique hybrid system that requires both a 3-prong outdoor electrical outlet and a standard 20-pound propane tank. In this setup, electricity powers the digital control board and a high-velocity Woodfire convection fan, while propane fuels the heavy-duty 3-burner gas system. To add authentic wood smoke flavor, it uses an integrated, electrically heated pellet box that burns just two cups of wood pellets, turning a master gas grill into a genuine smoker.

The Weber Searwood uses a pure wood pellet architecture. It relies entirely on a digital hopper, an internal auger, and a combustion fan to burn wood pellets as its sole source of both heat and flavor.

Rather than using a giant metal diffuser plate to block the firepot like traditional pellet grills, Weber engineered this model with an open DirectFlame system. This layout lets the fire interact directly with the grates, turning a classic pellet smoker into a high-heat searing machine that can hit 600°F without needing secondary gas burners.

Detailed Comparative Review: My Operational Experience

Design

Rolling the Ninja Flexflame onto my patio, its substantial build quality was instantly clear. Weighing in at a heavy 130 pounds, this machine feels incredibly solid. The distinct green finish gives it a rugged, modern look that stands out from standard black grills.

Its design relies on a heavy-duty, double-walled lid that traps heat exceptionally well, making it highly efficient even on windy days. Up top, the porcelain-enameled cast-iron grill grates are thick and retain heat beautifully. The side tables are solid and don’t flex when holding heavy trays of meat, and the built-in storage hooks keep tools organized right where you need them.

The Weber Searwood opts for a more compact, streamlined silhouette wrapped in a classic gloss-black porcelain-enameled finish. It takes up significantly less patio space than the sprawling Ninja, making it a much better fit for tighter decks.

Looking inside the cook box, you’ll find the real innovation: Weber has removed the massive, heavy flame deflector sheets found in older pellet grills. Instead, the bottom area is wide open, designed to let the pellet fire radiate heat directly upward. The build feels premium, the lid hinges smoothly, and the entire chassis is exceptionally well-balanced, sitting firmly on a heavy-duty cart that rolls easily over brick pavers or rough lawns.

Ease of Use

Getting a cook started highlights just how differently these two control systems operate. The Ninja Flexflame offers incredible out-of-the-box convenience if you are comfortable managing a two-fuel setup. You plug the 3-prong cord into an outdoor outlet, open your 20-pound propane tank, and use the front digital control panel to dial in your exact target temperature.

There is no need to twist dials or adjust burner valves to find the right temperature. The grill handles the gas flow automatically, blasting the cooking zone up to 600°F in just seven minutes. If you want to add smoke flavor, you simply fill the side box with two cups of pellets and press the Woodfire flavor button – the electric element takes care of the ignition automatically.

The Weber Searwood takes a little longer to preheat, requiring about 15 minutes to bring its wood fire up to temperature, but it shines when it comes to smart, hands-free automation. It features a Rapid React PID controller that monitors internal conditions constantly, adjusting the auger speed and fan to maintain rock-solid temperatures even in freezing weather.

The grill connects seamlessly to my phone via Wi-Fi and Bluetooth through the WEBER CONNECT app. I can drop a food probe into a pork shoulder, head inside, and track the internal temperature graphics, adjust the grill heat, or toggle the low-temperature SmokeBoost setting right from my couch without ever opening the lid.

Functions

When evaluating actual cooking versatility, both of these platforms deliver impressive performance through completely different styles of airflow. The Ninja Flexflame features a high-velocity convection fan that circulates super-heated air continuously around your food.

This 5-in-1 system allows you to grill, smoke, roast, griddle, or bake pizzas. When using the indirect roast rack, the convective airflow creates a stunning, even brown crust on whole chickens without requiring a rotisserie. If you swap out the grates for the full griddle plate, the gas burners deliver perfectly even, edge-to-edge heat for smashing burgers or searing bacon.

The Weber Searwood focuses on maximizing the natural properties of wood-fire cooking. Because it lacks a large metal barrier over the fire pot, its DirectFlame system creates beautiful, authentic sear marks on steaks and chops that are tough to replicate on traditional pellet grills.

If you want to slow-smoke a brisket, you can activate the SmokeBoost setting, which drops the temperature down to a steady 180°F. This lower temperature produces a thick, clean smoke stream that creates a deep, competition-grade smoke ring and an authentic backyard bark. Additionally, the manual mode overrides the automated PID logic, keeping the fan and auger running at a steady pace so you can cook with the main lid completely open when griddling or using the heavy-duty rotisserie accessory.

Maintenance

After a weekend of heavy cooking, cleaning up reveals the practical realities of managing these two different grill types. The Ninja Flexflame requires a two-part cleaning routine. The porcelain-enameled cast-iron grates wipe down easily with a standard grill brush, and grease channels smoothly into a front-access tray.

However, because the system uses an internal convection fan to move air rapidly throughout the cook box, fine grease mist and wood ash from the side pellet box can accumulate along the double-walled interior over time. You’ll want to regularly wipe down the fan housing and inner walls to prevent grease buildup.

The Weber Searwood is exceptionally easy to clean thanks to its open internal layout. Since there are no large grease trays or heat deflectors to scrape down, ash and food drippings fall directly into a bottom-mounted collection system.

The ashes sweep neatly into a removable drawer that you can slide out and empty into the trash in seconds. The internal walls are coated in a slick, baked-on porcelain enamel that resists grease buildup, and the Rapid React system features a high-heat burn-off cycle that cools the unit down quickly while carbonizing remaining food residue for easy brushing.
