Ninja FlexFlame 5-in-1 Grill and Smoker - Versatile Outdoor Cooker

Our review of the Ninja FlexFlame finds it best suited to backyard cooks who want one tool that covers grilling, smoking, roasting, griddling, and pizza making without juggling multiple appliances. The FlexFlame's standout is its combination of propane heat and powered convection, called CyclonicHeat-iQ, which produces consistently even results and speeds up cook times compared with conventional grills. Assembly is straightforward, controls are intuitive, and the mix of direct burners and a convection fan delivers reliable sear, smoke, and roast performance for families or small gatherings.

Key Features

• 5-in-1 Cooking: Grill, smoke, roast, griddle, and make pizzas with one outdoor unit, reducing the need for separate appliances.
• CyclonicHeat-iQ: Rapid convection heat circulates evenly for faster, more consistent cooking and better browning on meats and pizzas.
• Precision Burner Control: Dial in and maintain an exact temperature range from 200F to 600F for low-and-slow smoking or high-heat searing.
• Cyclonic Fan: High-velocity convection fan moves heat and air around food so there are no hot or cold spots across the main cooking area.
• Plug-in Electric Assist: Electricity powers the intelligent systems while a 20 lb. propane tank provides the heat, combining the benefits of both energy sources.

Who It's For

The FlexFlame is ideal for outdoor cooks who want versatility in one unit: families that prepare mixed menus, weekend hosts who alternate between smoked brisket and quick-seared steaks, and anyone who values precise temperature control for consistent results. It also suits buyers who prefer a stainless steel construction and a system that can handle multiple roles in an outdoor kitchen.

Those who should look elsewhere include buyers who need a pure pellet-only smoker or a completely freestanding electric grill; the FlexFlame requires both a 3-prong outdoor extension cord and a 20 lb. propane tank for full operation. Also, if you only want a simple portable grill for camping, this larger combination unit may be more than necessary.

Pros & Cons

Pros

• Excellent cooking performance with even heat and reliable smoke quality thanks to the convection fan and CyclonicHeat-iQ.
• Wide temperature range and precise burner dials make it easy to switch from low smoking to high-heat searing.
• Generous 424 sq in main cooking area fits multiple chickens, racks of ribs, or plenty of burgers for a family cookout.
• Included cast iron grates and roast & smoke rack offer flexible starting points out of the box.

Cons

• Requires both electricity and a 20 lb. propane tank, so it is not fully standalone for remote locations.
• Some specialized accessories like the Artisan Pizza Stone and griddle plates are sold separately if you want top performance for pizzas or griddle cooking.
