Smoke and Fire: A First-Hand Analysis of the Ninja Flexflame and Weber Searwood

The backyard cooking market has undergone a massive shift. Home cooks are no longer satisfied with simple, single-purpose grills that force them to choose between the speed of gas, the convenience of electricity, or the rich flavor of a traditional wood fire. Today’s outdoor chefs want a single machine that can handle it all: a system that can drop low for slow-cooked barbecue bark, hold a steady heat for baking, or open up wide for high-temperature searing.

This demand for ultimate versatility has brought two fascinating multi-functional platforms to the forefront: the dual-fuel Ninja Flexflame (PG301GN) and the smart, direct-flame Weber Searwood pellet smoker.

After a season of putting both units through intensive real-world testing – ranging from quick weeknight burgers to long, overnight slow smokes – I’ve gotten a clear view of how these different designs perform in the field. This isn’t a simple comparison of identical cookers; it’s a look at how a high-velocity convection gas hybrid matches up against a digitally automated, open-well pellet smoker. If you are trying to figure out which of these heavy-duty cooking systems deserves a spot on your patio, let’s break down the details.

The Core Concept: Ninja FlexFlame vs Weber Searwood Grill & Smoker

The practical difference between these two outdoor cookers comes down to how they manage heat and create flavor. The Ninja Flexflame is a unique hybrid machine that bridges the gap between gas speed and electric precision. It requires a standard 20-pound propane tank to generate raw cooking heat, alongside a 3-prong electrical connection to run its digital control board and high-speed convection fan.

To add authentic wood smoke flavor, it features an integrated side pellet box that burns a small amount of wood pellets using an electric heating element, allowing you to easily add real wood fire flavor to a high-capacity gas grill.

The Weber Searwood skips gas entirely, relying 100% on premium hardwood pellets for both its heat and flavor. It utilizes a digital hopper, an internal auger, and a combustion fan to feed and control a central fire pot.

What sets this model apart from traditional pellet smokers is its open DirectFlame architecture. By removing the large metal deflector plates that typically block the fire, Weber allows the natural flame to radiate heat directly up to the grates, allowing the smoker to hit a searing 600°F for authentic open-fire grilling.

In-Depth Performance Review: My Cooking Experience

Design and Build Quality

Stepping up to the Ninja Flexflame, its heavy-duty build quality is immediately apparent. Weighing 130 pounds, this is a substantial piece of outdoor machinery that feels rock-solid on your patio. The unique green finish gives it a fresh, modern aesthetic that sets it apart from traditional black grills.

The double-walled lid is heavy and retains heat beautifully, creating an efficient cooking chamber even on cold, windy days. The porcelain-enameled cast-iron grates are thick and hold heat exceptionally well, while the wide side tables offer plenty of prep space and feature handy built-in tool hooks to keep your gear organized.

The Weber Searwood takes a sleeker, more compact approach, making it an excellent fit for smaller decks or crowded patios. It features a classic gloss-black porcelain-enameled finish that is highly scratch-resistant and easy to clean.

Inside the cook box, the lack of traditional heavy flame deflector plates makes the interior feel surprisingly spacious and open. The cart frame is incredibly rigid, sitting on large, smooth-rolling wheels that make it easy to move the grill across uneven pavers or grass when rearranging your outdoor setup.

Everyday Usability and Ergonomics

Getting a cook started highlights a clear difference in how these two control systems operate. The Ninja Flexflame offers incredible convenience if you don’t mind managing two fuel sources. You plug in the electrical cord, open the propane valve, and use the front digital panel to set your exact target temperature.

The grill manages the gas burners automatically, heating the chamber up to a searing 600°F in just seven minutes. Adding wood smoke flavor is incredibly simple: you just fill the side box with two cups of pellets and hit the Woodfire button – the electric starter takes care of igniting the pellets automatically without any matches or lighter fluid.

The Weber Searwood takes a bit longer to preheat – requiring about 15 minutes to bring its wood fire up to temperature – but it excels at automated, hands-free cooking. Its smart Rapid React PID controller monitors internal cooking conditions constantly, adjusting the auger and fan speeds to hold your target temperature steady.

The grill connects effortlessly to your phone via Wi-Fi and Bluetooth through the WEBER CONNECT app. This lets you insert the included food probe, step away from the grill, and track your food’s progress, adjust temperatures, or activate the low-heat SmokeBoost setting right from your phone.

Cooking Performance and Flavor Output

When it comes to actual cooking versatility, both grills deliver fantastic results using completely different airflow methods. The Ninja Flexflame uses a high-velocity convection fan that circulates super-heated air continuously around your food.

This 5-in-1 system lets you grill, smoke, roast, griddle, or bake pizzas. When roasting a whole chicken on the indirect rack, this wrap-around airflow creates a beautifully crisp, even skin without needing a rotisserie. If you swap out the grates for the full griddle plate, the gas burners provide perfectly even, edge-to-edge heat that is ideal for searing smash burgers or frying bacon.

The Weber Searwood focuses on delivering rich, authentic wood-fire flavor. Because it doesn’t have a metal barrier over the fire pot, its DirectFlame system creates beautiful sear marks on steaks that are tough to get on traditional pellet smokers.

For low-and-slow barbecue, the SmokeBoost setting drops the temperature to a steady 180°F, producing a thick, clean smoke stream that creates a deep smoke ring and an authentic backyard bark on pork shoulders or ribs. Plus, its manual mode keeps the fan and auger running at a steady speed even when the main lid is open, making it perfect for open-lid griddling or using the heavy-duty rotisserie accessory.

Cleaning and Maintenance Workload

After a long weekend of cooking, cleaning up shows the practical side of maintaining these two different grill styles. The YETI-style slick porcelain-enameled walls of the Weber Searwood make it incredibly easy to clean.

Because it lacks large heat deflectors, ash and food drippings fall directly into a bottom collection system. The ash sweeps easily into a removable drawer that you can slide out and empty in seconds. The internal walls resist grease buildup, and the grill features a high-heat burn-off cycle that carbonizes food residue for quick brushing.

The Ninja Flexflame requires a two-part cleaning routine. While its cast-iron grates wipe down easily and grease channels smoothly into a front tray, its high-speed convection fan can circulate a fine mist of grease and wood ash across the inner walls over time.

To keep the system running efficiently, you’ll need to regularly wipe down the fan housing and double-walled interior. The premium nonstick surfaces clean up quickly, but the extra moving parts mean you’ll want to spend a few extra minutes maintaining the interior compared to the simple, open tub of the Weber.

It is an ideal option for busy households that want a fast, high-capacity outdoor cooker for everything from weeknight pizzas to weekend griddling.

On the other hand, if you are an outdoor cooking purist who wants true wood-fire flavor, smart app automation, and effortless cleanup, the Weber Searwood is the clear winner. Its pure pellet design delivers rich, authentic barbecue flavor, and its open direct-flame setup lets you sear steaks over an open fire without needing gas tanks. The excellent app connectivity makes it incredibly easy to manage long, slow cooks from your phone, and the slide-out ash drawer makes cleanup quick and simple. For pellet enthusiasts and tech-minded backyard chefs, the Weber Searwood is my top recommendation.

Frequently Asked Questions

1. Can I use the Ninja Flexflame strictly as a propane gas grill without plugging it into an electrical outlet?

No, the Ninja Flexflame requires a connected 3-prong outdoor electrical source to run. While propane provides the actual cooking heat, the electricity is necessary to power the digital control panel, the automated gas valves, and the high-velocity convection fan that circulates heat throughout the cook box.

2. How does the Weber Searwood handle grease flare-ups without a traditional flame deflector plate?

The Searwood uses a specially angled cook box floor and targeted drip channels that quickly direct grease away from the central firepot and down into the bottom collection drawer. This ensures that while you get direct heat for searing, large pools of grease never sit near the open flame, keeping flare-ups to a minimum.

3. Do I have to use Ninja brand pellets in the Flexflame’s side woodfire box?

While Ninja recommends their own branded wood pellets for optimal flavor development, the electrical pellet box can comfortably burn any high-quality, 100% hardwood food-grade pellets designed for outdoor grills and smokers.

4. Can the Weber Searwood maintain stable cooking temperatures during freezing winter weather?

Yes, the Rapid React PID controller monitors internal temperatures constantly and adjusts the pellet feed rate and fan speed automatically to compensate for cold weather, ensuring a steady temperature even when it’s freezing outside.

5. Is the griddle insert included with the purchase of the Weber Searwood 600?

The Weber Searwood comes standard with heavy-duty porcelain-enameled steel cooking grates. The rust-resistant griddle insert, heavy-duty rotisserie kit, and custom WEBER CRAFTED grillware are specialized accessories that are sold separately.
