What Is the Ninja OG850?
At its core, the Ninja OG850 Woodfire Pro XL is a 4-in-1 outdoor cooking system that enables users to switch between Master Grill, BBQ Smoker, Outdoor Air Fryer, and Bake modes. Each of those four functions is genuinely capable — not a watered-down version tacked on as a bonus feature, but a distinct cooking mode with its own temperature range and technique.
The headline innovation is Ninja's Woodfire Flavor Technology. Both the OG850 and comparable models are 100% electric — the wood pellets are not used for fuel. Instead, they sit in a small smoke box and smolder to produce smoke, while the actual heat comes from electric heating elements. That means you get consistent, controllable heat with genuine wood-smoke flavor — without the volatility of a charcoal fire or the hassle of managing a full pellet hopper.
The 180 square inches of cooking space represents 30% more capacity than the original Ninja outdoor grill, and it fits up to 2 full racks of ribs, 10 burgers, 4 lbs of wings, or 2 whole chickens simultaneously. For most households and patio gatherings, that's more than enough real estate to cook everything at once.
The Four Cooking Modes, Explained
Master Grill — Sear Marks, Real Heat, No Propane Tank
The grill mode is where most owners will spend the majority of their time. During testing, the OG850 reaches 500°F in about 10 to 12 minutes — competitive with gas and far faster than charcoal. The nonstick grill grate produces genuine sear marks, and because the heat source is electric, there are no unpredictable hot spots caused by flare-ups.
Preheat times vary by function and temperature level: Grill Low takes approximately 9 to 11 minutes, Grill Medium around 10 to 12 minutes, and Grill High roughly 13 to 15 minutes when using Woodfire Flavor Technology, due to the added pellet ignition cycle. That ignition cycle is automatic — the unit handles it without any manual intervention.
BBQ Smoker — Authentic Low-and-Slow Results
This is the feature that sets the OG850 apart from every other electric outdoor grill on the market at this price point. Using just half a cup of pellets, the unit creates a substantial amount of smoke. Testing with the "Robust Blend" pellets on wings produced a deep, mahogany color and genuine wood-smoke flavor typically associated with a large offset smoker.
The smoker mode operates at low temperatures — as low as 145°F, at which point it switches to a cold smoke mode. For long cooks like brisket or pork shoulder, this is exactly where you want to be. Running BBQ Smoke mode at around 225°F for three hours produces a perfect bark — not overpowering, but clearly authentic wood flavor.
Two pellet varieties are included in the box: the package comes with a pellet scoop and two starter packs of Ninja Woodfire Pellets in Robust and All-Purpose Blends. The Robust Blend delivers bold hickory-style smoke suited to beef and pork, while the All-Purpose Blend is a gentler, more versatile option for poultry and vegetables.
Outdoor Air Fryer — Crispy Results Without the Kitchen
The Air Crisp mode is one of the OG850's most underrated features. Cooking frozen fries at 390°F for 18 minutes, then finishing at 425°F for a further 5 minutes, produces excellent results: crispy, evenly browned exteriors with a fluffy centre. For a patio session, this means you don't need to disappear inside to cook sides — the whole meal happens outside.
One of the standout techniques enabled by having an air fryer on a grill is finishing smoked food with a crisp. Smoking chicken wings first and then switching to Air Crisp for 10 to 15 minutes produces perfectly crisp skin — a combination you simply can't achieve with a standard grill.
Bake Mode — More Than a Novelty
Bake mode uses the enclosed cooking environment and convection heat to function genuinely like an outdoor oven. Air-frying in tests — including sweet potato wedges — was superb, and the smoke infusion made a noticeable difference to the flavour profile. This mode opens up possibilities beyond meat: think cornbread, skillet cookies, roasted vegetables, or even a pizza finishing pass.
Built-In Thermometer: No More Guesswork
A key feature of the OG850 is its built-in thermometer, which allows for precise temperature control and ensures that food is cooked to the desired level of doneness. The probe inserts into the thickest part of the protein, and the display shows a live internal temperature reading — no need for a separate instant-read thermometer or repeated lid-lifting that bleeds heat.
For best results, the thermometer should be inserted lengthwise into the thickest part of the ingredient, and food should be allowed to rest for 3 to 5 minutes after cooking is complete. The unit also supports a manual target temperature setting, so you can set a doneness goal and let the grill alert you when it's reached.
For those who cook two proteins at once and want dual-probe monitoring, Ninja's OG951 Pro Connect Premium XL adds a second thermometer port — but for the majority of cooks, the single probe on the OG850 handles the job without complications.
Design, Build Quality & Portability
The OG850 arrives in a clean, professional Dark Grey finish that reads as serious outdoor equipment rather than cheap patio furniture. The grill measures 20.3 inches wide, 22.28 inches deep, and 15.82 inches tall, operating at 1,760 watts and offering impressive cooking capacity for family gatherings and entertaining.
The premium materials are designed to withstand outdoor use and year-round cooking, and the unit is fully weatherproof — once positioned, it can be left on the patio safely. After extended outdoor use, reviewers consistently report no rust, no fading, and solid grate integrity.
Despite the XL designation, the footprint is compact enough for apartment balconies, RV hookups, and tailgating setups. The size is a genuine advantage — it doesn't take up the room of a traditional smoker, while still delivering comparable flavour results.
Cleanup is straightforward. All fat drains through a hole at the back of the grill and into a drip tray. Ninja supplies disposable drip tray liners for convenience, and the steel tray itself washes quickly after each session. The grill grate and crisper basket require hand washing — not dishwasher safe — but the non-stick coating means food release is easy and scrubbing is minimal.
What's in the Box
The OG850 package includes the grill unit, a 180 sq. in. nonstick grill grate, built-in thermometer, crisper basket, grease tray with disposable liner, pellet scoop, and two starter packs of Ninja Woodfire Pellets in Robust and All-Purpose Blends.
Everything needed to start cooking is included on day one — no separate accessory purchases required before the first session.
Power & Setup Requirements
The OG850 plugs into a standard 3-prong grounded GFCI outlet. For extension cords, only outdoor cords marked "SJOW" and "suitable for use with outdoor appliances" should be used — 14 gauge for cords up to 25 feet, and 12 gauge for cords between 25 and 50 feet. Cords longer than 50 feet are not recommended. This is an important practical note for users who plan to run the grill at a distance from their outdoor outlet.
No assembly is required beyond unboxing. The unit is ready to cook from the moment it's placed on a flat outdoor surface and plugged in.
Real-World Performance: What Owners Say
Users have praised the OG850 for its ease of use, strong build quality, and the quality of smoky flavour it imparts. From slow-smoked briskets to quick-seared steaks, results are consistently satisfying — even self-proclaimed BBQ purists found it an impressive alternative to charcoal or gas, particularly in terms of flavour and cleanup.
One owner reported selling their large 5-burner gas grill after acquiring the OG850 and stated they don't miss it at all. That's a telling endorsement from someone who made the switch after years with conventional equipment.
Minor criticisms include the short power cord on some units, the non-dishwasher-safe grates, and the absence of app connectivity — all valid points, though none affect core cooking performance. The Ninja Woodfire Pro XL strikes a strong balance between versatility, performance, and convenience, delivering solid value for those who want wood-smoked flavour without the complexity of traditional smokers.

The OG850 occupies a compelling sweet spot: more versatile than the Weber Lumin (which lacks any smoke capability), more beginner-friendly and cleaner to operate than the Traeger Ranger (which uses pellets as fuel and requires more management), and more affordable than the Ninja OG951 while sharing the same core cooking architecture.
Who Should Buy the Ninja OG850?
The OG850 is the ideal choice for casual grillers who enjoy woodfire flavour — it offers lower cost, simple manual operation, and reliable XL cooking without the complexity of app connectivity or dual-probe management.
It's the right grill for:
- Apartment and condo dwellers who can't use open-flame or charcoal equipment on their balconies
- Families who want to feed a crowd without babysitting a charcoal fire for two hours
- Curious home smokers who want to try low-and-slow cooking without investing in a dedicated offset smoker
- Outdoor entertainers who want one machine that handles the ribs, the wings, the sides, and the dessert
- RV and tailgate cooks who need capable equipment in a compact, portable format
The Ninja OG850 Woodfire Pro XL is a rare piece of outdoor cooking equipment that genuinely delivers on its promise. The four cooking modes are all capable. The Woodfire Flavor Technology produces authentic smoked flavour from a half-cup of pellets. The 180 square inches of cooking space handles serious volumes of food. And the built-in thermometer removes the single biggest variable in outdoor cooking — knowing exactly when your meat is done.
It's not a replacement for a competition-grade offset smoker or a full-size six-burner gas grill. But for the overwhelming majority of outdoor cooks — those who want great results, clean operation, and a machine that does more than one thing well — the OG850 is one of the most practical and satisfying outdoor cookers available at its price point.
