7 Best Ninja Full Size Grills of 2026

This game-changing indoor powerhouse delivers restaurant-quality sear marks and smokeless countertop grilling without sacrificing kitchen comfort. With 500°F cyclonic grilling technology and a dual-sensor Smart Thermometer, the Ninja Foodi Smart XL FG551 nails precision cooking for steaks, chicken, and even delicate fish. It’s engineered for home chefs tired of guesswork—its SMART COOK SYSTEM eliminates undercooked meals and dry proteins by syncing doneness levels with protein type, making it ideal for families and weeknight warriors.

In real-world testing, the 6-in-1 versatility shines: air frying wings achieves golden crispness with up to 75% less fat, while roasting vegetables or dehydrating fruit proves consistent. The XL capacity handles six steaks or a full tray of hot dogs, though dense meals may require batch cooking due to uneven airflow when overcrowded. The smoke control system lives up to its name—minimal smoke even during high-heat searing—but fatty meats still trigger some odor, especially without the splatter shield. It’s best suited for apartment dwellers or indoor grilling enthusiasts who want outdoor flavor without the mess.

Compared to the Ninja IG651, this model lacks the flat top griddle but offers a simpler, more intuitive interface for users prioritizing smart thermometer accuracy over multi-surface cooking. It stands out among indoor grills by balancing intelligence, capacity, and health-conscious frying, though it can’t match the open-flame experience of outdoor pellet grills. For those seeking a set-it-and-forget-it countertop griller with pro-level doneness control, the FG551 delivers where it counts—smart cooking meets consistent results.

If you’re after authentic woodfire flavor without propane or charcoal, the Ninja OG301 is a budget-smart electric grill that punches above its weight. Powered by 1760 watts of electric heat and real wood pellets, it delivers tangy bark and deep smoke rings on brisket and ribs—something most indoor grills can’t replicate. Its foolproof pellet system uses just half a cup for full smokes, making it incredibly efficient and beginner-friendly, while the 141-sq-in cooking surface handles six steaks or a party-sized wing batch with ease.

During testing, the OG301 impressed with low-and-slow smoking performance, maintaining stable temps for 4+ hours with minimal monitoring. The weather-resistant body held up in light rain, though extended wet exposure caused minor pellet dampness—using the optional cover is recommended. While it lacks Bluetooth connectivity or a built-in thermometer, the consistent heat distribution and easy pellet ignition make it reliable for casual grillers. It struggles slightly with high-heat searing compared to gas grills, peaking around 500°F, but still delivers solid char on burgers and sausages.

Priced lower than premium models like the OG951GN2, the OG301 sacrifices smart features but retains core woodfire performance, making it ideal for apartment balconies, small patios, or tailgaters needing real smoke flavor without open flames. For those stepping into pellet grilling without overspending, this model offers maximum flavor return on investment—outperforming its price bracket with true BBQ authenticity and compact practicality.

The Ninja IG651 is the ultimate indoor grill hybrid, combining a 500°F pro power grate with a 12-inch flat top griddle to conquer everything from smash burgers to pancakes. This isn’t just a grill—it’s a full breakfast-and-dinner station that lets you sear steaks while frying eggs, all with edge-to-edge heating that eliminates cold spots. For home cooks craving diner-style versatility, the ability to cook with the hood up or down unlocks true culinary flexibility: open for intense direct heat, closed for cyclonic crisping and even roasting.

Real-world use confirms its dominance in multi-tasking meals: air frying wings in the basket while griddling bacon and eggs saves time and counter space. The Smart Thermometer performs flawlessly across 9 doneness levels, especially with thick-cut steaks and chicken breasts. However, the dual-layer cooking setup demands attention—overloading the griddle reduces airflow, impacting crispness in air fry mode. Still, the nonstick ceramic coating and dishwasher-safe parts make cleanup a breeze, even after greasy breakfast spreads.

Against the FG551, the IG651 adds griddle functionality and slightly better heat control, making it the clear upgrade for families or meal preppers. While bulkier, it justifies its footprint with unmatched indoor cooking range. It doesn’t match outdoor pellet grills in smoke depth, but for urban kitchens needing a do-it-all appliance, the IG651 stands tall—offering broader functionality and superior surface control than any other Ninja indoor model.

This flagship outdoor beast redefines smart grilling with Bluetooth-enabled app control, 180 square inches of cooking space, and true woodfire flavor—earning its title as the best overall Ninja grill. The Ninja ProConnect app transforms cooking: set temps, monitor two proteins, and get flip alerts on your phone, so you’re never stuck babysitting the grill. Whether smoking a 10-lb brisket or air frying wings with real wood pellet infusion, the OG951GN2 delivers restaurant-tier results with zero guesswork.

In extended testing, the 7-in-1 functionality proved remarkably consistent—baking pizza at 500°F yielded crispy crusts, while dehydration mode preserved herbs evenly over 8 hours. The built-in thermometer pairs with the app to track internal meat temps in real time, a game-changer for holiday feasts or large cookouts. Even in wind or light rain, the weather-resistant build maintained stability, though pellet efficiency dipped slightly in colder temps. It preheats slower than gas grills (15–20 mins), but compensates with flavor depth and automation.

Compared to the OG751, it offers larger capacity and app integration, making it ideal for entertainers and tech-savvy grill masters. While pricier, it justifies the cost with remote monitoring, expansive cooking area, and multi-protein precision. For those who want the most versatile, connected, and flavor-rich outdoor grill, the OG951GN2 outclasses rivals by blending intelligence, size, and authentic woodfire performance in one elite package.

The Ninja PG301BL FlexFlame is a gas and electric fusion marvel, merging propane-powered 600°F searing with electric super-heated air for the most versatile outdoor cooking system in the lineup. With 3 burners and 424 sq. in. of cooking space, it handles everything from a full turkey to 18 burgers—perfect for large gatherings or serious weekend cooks. The digital control panel maintains precise temps from 200°F to 600°F, eliminating flare-ups and hot spots common in traditional grills.

Testing revealed exceptional roasting and pizza-making potential—when paired with the optional Artisan Pizza Stone, it bakes a 16-inch pie in under 5 minutes with a charred, Neapolitan-style crust. The Super-Heated Continuous Air system ensures even smoke circulation during low-and-slow smokes, while the Woodfire BBQ Smoker mode adds rich flavor with just 2 cups of pellets. However, the need for both propane and electricity limits portability, and setup is more complex than all-electric models.

Against the OG951GN2, it trades app connectivity for greater raw power and griddle expansion options, making it better suited for outdoor kitchens or RV setups where space and accessories aren’t limited. It’s not balcony-friendly due to open flame, but for backyard chefs wanting gas-level heat with convection cooking benefits, the PG301BL delivers unmatched outdoor adaptability—combining flame, airflow, and modular upgrades into one powerhouse system.

The Ninja OG751 stands out with its built-in thermometer—a rare feature that makes it perfect for hands-off BBQ perfection. This 7-in-1 electric grill delivers authentic woodfire flavor using real hardwood pellets, allowing you to smoke, grill, bake, and even air fry—all without propane or charcoal. The 141-sq-in nonstick grate handles six steaks or a full rack of ribs, while the crisper basket adds smoky crunch to fries and wings cooked entirely outdoors.

In practice, the built-in thermometer is a game-changer: it vibrates and beeps when food hits target doneness, so you can relax during long smokes instead of checking every 10 minutes. The woodfire technology produces visible smoke and deep flavor, though it takes longer to preheat than gas grills—about 12–15 minutes. While it lacks app control, its simple, reliable interface appeals to users who want smart features without digital clutter.

Compared to the OG301, it offers better feedback with the thermometer and includes two pellet blends for varied flavor profiles. However, it falls short of the OG951GN2 in capacity and connectivity. For urban grillers who want built-in doneness alerts and real smoke flavor without open flames, the OG751 is the smart middle ground—offering more intelligence than budget models and better feedback than basic electric grills.

The Ninja OG321 is the most functionally complete electric outdoor grill, offering 6-in-1 versatility—grill, smoke, bake, roast, air fry, and broil—all infused with 100% real woodfire flavor. With the same 1760-watt electric core and 141-sq-in cooking space as the OG301, it adds broil mode for finishing steaks with a crispy top, making it a step up in culinary range. The crisper basket transforms it into an outdoor air fryer, letting you cook sides with smoky depth while grilling mains.

Real-world tests show consistent performance across all functions: smoking brisket yields tender bark, while broiling salmon gives a caramelized finish. The half-cup pellet system remains efficient and beginner-safe, ideal for small-space cooking on balconies or patios. However, like other electric models, it can’t match gas grills in sear speed, and broil mode takes longer than expected—about 8–10 minutes for medium doneness on thick cuts.

When compared to the OG301, the OG321 adds broil functionality for better finishing power, but doesn’t expand capacity or add smart features. For users who want maximum cooking modes in a compact, flame-free design, it’s the best 6-in-1 option—delivering broader function than basic models while maintaining the same space-saving, smoke-smart advantage.
