The Flex Flame platform has redefined hybrid outdoor cooking by combining active electric convection air circulation with raw propane burner power. Known for giving backyard chefs and campsite cooks precise digital temperature control alongside authentic woodfire pellet smoke, this system bridges the gap between conventional gas grills and dedicated outdoor smokers. Rather than relying on simple ambient radiant heat, the lineup utilizes high-velocity airflow to seal in juices, crisp exteriors quickly, and maintain steady heat across a spacious cooking chamber.

While the flagship outdoor cooking station provides the versatile multi-burner foundation, the supporting ecosystem consists of tailored half-size griddle plates, specialized pizza stones, secondary warming racks, and heavy-duty replacement grates designed to customize your setup for specific recipes and cooking styles.

The Ninja FlexFlame Grill & Smoker serves as the central hub of this modern outdoor cooking platform. Operating as a comprehensive 5-in-1 outdoor cooking system, this machine allows you to grill, smoke, roast, griddle, and bake artisan pizzas within a single self-contained footprint. At its core, the unit blends corded electric digital controls with standard propane heat. The precision gas system regulates flame output between 200°F and 600°F across three dedicated burners, while an integrated convection fan pushes superheated continuous air around your food to create crisp outer edges and prevent hot spots. A quick preheat cycle brings the cooking chamber up to 600°F in just seven minutes for immediate high-heat searing.

Outdoor cooks who appreciate true barbecue flavor will value the integrated Woodfire technology. By loading just two cups of wood pellets into the removable pellet box, you can generate authentic wood smoke, distinctive bark, and visible smoke rings on slow-cooked ribs or brisket. The primary cooking grid offers 424 square inches of surface area, which provides enough room to hold up to three 7-pound whole chickens, four full racks of ribs, or 18 individual burger patties. The cooker comes packaged with two porcelain-enamel cast-iron grill grates, an indirect roast and smoke rack made from porcelain-enamel-coated steel, six convenient utensil side hooks, a slide-out grease tray, and the pellet smoke box.

This master unit suits patio cooks and mobile tailgaters who desire culinary flexibility without managing multiple standalone appliances. Because it requires a three-prong outdoor electrical extension cord alongside a standard 20-pound propane cylinder, it is best suited for campsites and home decks with reliable power access. If you only plan to cook quick burgers on flat surfaces, a standalone griddle plate might suffice, but anyone seeking precise convection smoking and master gas performance should start with this primary saker plus torch compatible cooking station, especially if you want the full potential of the ninja flexflame grill and smoker platform.

Ninja FlexFlame Half-Size Griddle with Grease for Breakfast and Searing

Ninja FlexFlame Half-Size Griddle with Grease
Ninja FlexFlame Half-Size Griddle with Grease

Best for: Campers wanting diner smash burgers and breakfast

What the listing says

  • COMBO COOKING Grill and griddle at the same time to satisfy any craving, any time.
  • DIRECT, EVEN HEAT Even, edge-to-edge griddling and sizzling.
  • PROFESSIONAL-GRADE GRIDDLE Carbon steel griddle plate is rust-resistant and durable.
  • FEED A CROWD Fits 8 fried eggs, 6 pancakes, or 6 smash burgers.
  • BUILT-IN GREASE DRAIN Designed for convenient grease management while cooking.

Pros

  • Heavy carbon steel build
  • Built-in grease drainage port
  • Direct edge-to-edge heat

Cons

  • Requires routine seasoning
  • Designed specifically for PG300

Expanding your grates with flat-top cooking capacity is simple with the Ninja FlexFlame Half-Size Griddle with Grease drain insert. Manufactured specifically for the PG300 series under model number XSKHLFGRIDLE, this carbon steel accessory drops into place directly over one side of the burner box after pulling out a single grill grate. By occupying exactly half of the cooking chamber, the plate establishes a dual-zone setup that allows you to fry smash burgers or vegetables on the griddle plate while concurrently charring steaks over open flame on the remaining cast-iron grate.

Durability and heat dispersion are major strengths of this official component. Built from commercial-grade carbon steel, the rectangular plate delivers edge-to-edge heat uniformity without warping under elevated flame settings. The cooking area is engineered to feed a crowd, comfortably holding up to eight fried eggs, six large pancakes, or six quarter-pound burger patties simultaneously. A dedicated grease drain port funnels drippings directly into the base unit catch system, preventing grease pooling and dangerous flare-ups during greasy cooks.

This heavy carbon steel insert is ideal for campsite breakfast lovers and burger specialists who want direct, high-conductivity flat-top performance. It requires typical carbon steel maintenance, including light oiling after washing to preserve its rust-resistant properties. Grillers who prefer a completely maintenance-free ceramic nonstick finish might lean toward aftermarket options, but this factory-designed ninja flexflame half-size griddle represents the gold standard for rugged searing and authentic diner-style crust development on any ninja flexflame pg301 appliance.

  • Third-party branded component

The Utheer Half Griddle Plate for FlexFlame offers an alternative flat-top solution for owners of the PG300 series, including the PG301, PG301BL, PG301BK, PG301GN, and PG305 variants. Measuring 16.9 inches long by 12.3 inches wide with a 1.5-inch profile, this third-party insert matches the physical footprint required to replace half of your primary grill grate system. Constructed from a sturdy cast-iron substrate, it is finished with a smooth ceramic nonstick coating designed to prevent delicate breakfast proteins, fish fillets, and chopped vegetables from sticking to the hot surface.

Unlike raw steel or bare iron cooking surfaces that require rigorous curing routines, the ceramic coating on this griddle plate is ready for immediate outdoor cooking. The smooth nonporous face wipes clean with warm soapy water and a soft rag, eliminating the prolonged scrubbing routines often required after making greasy bacon or barbecue glazes. Because it occupies only one half of the cooking bay, you retain direct flame access on the open side, giving you the versatility to sear chicken breasts while sautéing fajita peppers adjacent to the burner.

This accessory appeals directly to on-the-go RVers and patio cooks who prioritize fast meal cleanups and effortless release over traditional cast-iron seasoning. While aggressive metal spatulas can damage ceramic layers over time, cooks who use silicone or wooden utensils will appreciate how easily eggs slide across the surface. It serves as a sensible entry when exploring third-party flexflame pg300 accessories to upgrade your daily outdoor meal preparation.

  • Includes peel and scraper
  • Heavy ceramic heat retention

Cons

  • Heavier 6.44 kg total package
  • Requires dedicated storage room

The 16 Inch Square Pizza Stone Kit turns your outdoor convection cooker into an authentic artisan pizza oven. Engineered by DcYourHome to fit the PG300 chassis, this comprehensive baking kit features a thick 16-inch by 16-inch square ceramic stone capable of withstanding extreme thermal loads up to 932°F (500°C). The heavy ceramic core absorbs radiant heat from the propane burners below, distributing thermal energy evenly across the entire surface to rapidly draw moisture out of dough, yielding a blistered crust and bubbly cheese in just minutes.

In addition to the high-density baking stone, this three-piece package includes a stainless steel pizza peel, a cleaning scraper, and a specialized maintenance cloth. The wide stainless steel peel provides a secure, heat-resistant method for sliding raw dough onto the scorching stone and retrieving bubbling pizzas without singeing your arms. Beyond traditional Neapolitan pies, the thermal mass of the ceramic tile allows you to bake artisan boules, focaccia, and flatbreads that rival outcomes produced on an emile henry pizza stone inside an indoor kitchen oven.

Weighing 6.44 kilograms, this stone kit is built for serious home bakers who demand maximum heat retention and professional-grade handling tools. It does add considerable weight to your mobile travel kit, making it better suited for home patios or extended RV basecamps than quick tailgates. If your culinary ambition includes mastering high-heat crusts on a flexflame pizza stone, this purpose-built bundle provides all the requisite gear in a single package.

Cons

  • Third-party accessory
  • Reduces upper lid clearance

When cooking large batch meals for crowds, the Adjustable Expandable Griddle Warming Rack provides the secondary elevated tier needed to maximize vertical cabinet volume. Manufactured by SafBbcue from food-grade stainless steel, this universal warming shelf rests safely above your main grates or griddle plates. Its defining feature is a sliding telescoping frame that expands in length from 15 inches to 22 inches, allowing you to tailor the width of your upper cooking deck to match whatever grate or griddle configuration you have installed below.

Elevating food away from direct burner flames creates a dedicated indirect heat zone, making this rack the ideal perch for slow-roasting delicate sides while high-heat searing continues below. The stainless steel construction holds up to heavy items without bending, easily accommodating up to three racks of ribs, 18 whole potatoes, or 15 ears of corn. The wire spacing allows the convection fan to circulate hot air and woodfire smoke freely around food, ensuring consistent flavor penetration. Folding legs collapse completely flat against the frame, streamlining packing inside a camper drawer or portable gear bin.

This expandable tier is tailored for camp cooks and family hosts who frequently run out of primary grate space when organizing large gatherings. Because it is completely dishwasher safe and corrosion-resistant, maintaining the stainless steel wire requires zero seasoning. Think of it as an adjustable secondary stage similar to an elevated heat buffer or pit boss heat deflector setup, offering indispensable indirect warming when outfitting your flexflame warming rack configuration.

Pros

  • Heavy-duty SUS304 steel
  • Thick 7mm solid rods
  • Holds up to 125 pounds

Cons

  • Adds eight pounds to setup
  • Direct grate without griddle flat

The SUS304 7MM Stainless Steel Grill Grates from FlameDuty provide an industrial-strength alternative to factory porcelain-coated cooking grids. Designed as a direct drop-in replacement set for the PG300 series under original reference XSKGRILLGRATE, this two-piece pack fits seamlessly inside the FlexFlame cook box. Each individual grate is welded from solid 7mm thick bars of non-magnetic SUS304 food-grade stainless steel, delivering exceptional thermal conductivity, corrosion resistance, and high structural rigidity that can support up to 125 pounds of meat across its cooking surface.

A primary benefit of solid stainless steel grates is their imperviousness to the chipping, flaking, and rust that can plague coated iron over prolonged outdoor exposure. Even when subjected to aggressive wire cleaning brushes or acidic marinades, the heavy-duty rods retain their structural integrity and smooth exterior finish. The 7mm diameter metal rods store substantial thermal mass, creating deep, defined sear lines on steaks, pork chops, and dense vegetables while releasing food cleanly once hot.

This premium grate package is suited for demanding outdoor cooks who run their grills frequently in humid coastal conditions or rugged travel environments where moisture destroys lesser metals. While heavier than thin-wire aftermarket grates at eight pounds for the set, their longevity surpasses standard coated steel grates found on a traditional red weber grill. If you want permanent, worry-free cooking bars that never chip or peel, upgrading to these heavy-gauge flexflame grill grates provides lasting peace of mind.

Before you choose

How to Choose the Right Flex Flame Grills and Grill Accessories

Selecting the ideal components for your outdoor kitchen starts with understanding how the base machine operates and identifying where your cooking style requires expansion. The foundation of the system is the hybrid cooker itself, which relies on a combination of electric convection technology and propane flames. If you do not yet own the primary cook box, investing in the base unit provides 424 square inches of porcelain-enamel cast-iron cooking space along with a smoke box, grease management hardware, and a roasting rack right out of the box.

When determining which flexflame accessories to buy, evaluate the styles of meals you cook most frequently outdoors. If morning breakfasts, delicate seafood, and crispy smash burgers dominate your menu, a half-size griddle plate is the most practical first addition. Choose the official carbon steel model if you value extreme high-heat searing and traditional diner-style crust development, or select the ceramic-coated cast-iron plate if you want an easy nonstick surface that wipes clean without the recurring seasoning demands of bare metal.

Baking enthusiasts and tailgaters who want authentic pizza parlor performance should prioritize the heavy 16-inch ceramic pizza stone kit. Because the base cooker reaches 600°F and circulates superheated air via its high-velocity convection fan, the stone absorbs tremendous bottom heat while the convection current melts toppings from above. The inclusion of a dedicated peel and cleaning tools makes this kit a self-sufficient baking package for your outdoor deck or camper setup.

Finally, examine your capacity and longevity requirements. If you frequently host large family barbecues or need to keep sides warm while searing main proteins, adding an expandable stainless steel warming rack doubles your practical vertical cabinet space. For long-term grill preservation, swapping out standard porcelain grates for solid 7mm SUS304 stainless steel grids ensures your cooking deck never chips, rusts, or flakes under heavy travel abuse, guaranteeing dependable performance for years to come.

Questions people ask

FAQ

What fuel does the Ninja FlexFlame grill require to operate?

The system utilizes a dual-power architecture that requires both corded electricity and propane fuel. Electricity powers the digital control display, internal sensors, and the high-velocity convection fan that circulates heat throughout the cook box. Propane fuel supplies the raw thermal energy for the three precision burners. To cook outdoors, you must connect the appliance to a standard 20-pound propane tank and plug it into a grounded three-prong outdoor electrical outlet or extension cord.

Can you cook on a griddle and open grill grates simultaneously?

Yes, the cooking chamber is designed to accommodate split configurations. By removing one of the two standard grill grates, you can insert a half-size griddle plate on one side while leaving the remaining open grate over the opposite burner. This arrangement allows you to prepare bacon, fried eggs, or delicate vegetables on the flat griddle surface while searing steaks, burgers, or chicken breasts over direct flames at the same time.

What is the difference between carbon steel and ceramic griddle plates?

Carbon steel griddle plates are industrial-grade metal surfaces that excel at edge-to-edge heat conduction and durable high-temperature searing, though they require routine light oiling to maintain rust resistance. Ceramic-coated griddle plates feature a smooth nonstick layer over a cast-iron core, allowing food to release easily without seasoning routines. Ceramic plates clean up quickly with water and gentle wiping, but they require softer utensils to avoid scratching the surface.

Do aftermarket accessories fit all Ninja FlexFlame PG300 models?

Most half griddles, replacement grates, warming racks, and pizza stones engineered for the PG300 series fit universally across model variations, including the PG301, PG301BL, PG301BK, PG301GN, and PG305. Because these cookers share the same structural firebox dimensions and burner layouts, drop-in accessories sized for the PG300 platform seat cleanly inside the interior support ledges regardless of the base unit exterior color.

How does the Woodfire smoking feature work on the FlexFlame grill?

The integrated smoking system uses a specialized pellet box mounted to the side of the cooking chamber. By adding two cups of food-grade hardwood pellets and selecting the smoker setting on the digital interface, an electric heating element ignites the pellets to produce real wood smoke. The internal high-velocity fan actively circulates this smoke across the food, creating authentic barbecue bark and distinct smoke rings during low-and-slow cooking sessions.
