Ninja Pizza Stones: Genuine FlexFlame vs Woodfire-Compatible Kits

The Ninja FlexFlame 16’’ Artisan Pizza Stone is the only genuine Ninja accessory here. It is a cordierite stone for 16 inch artisan pizzas, and Ninja says you can make one in as little as 5 minutes. The FlexFlame heats from the top down, which Ninja says gives crispy crusts and melted cheese.

The stone is heat safe up to 600°F, weighs 7.4 pounds and comes with a start guide. Ninja recommends pairing it with its 16” perforated pizza peel, sold separately. Beyond pizza, it handles breads and calzones. The critical detail is compatibility: it is built exclusively for the PG300 series.

If you own a FlexFlame, this is the safest match, since it is designed alongside the grill. If you want a peel and scraper in the box, the DcYourHome kit is the third-party alternative. For more on the wider product family, see our overview of Ninja smart appliances.

• Genuine Ninja cordierite stone
• 16 inch pizzas in about 5 minutes
• Heat safe to 600°F
• PG300 series only

Best for
Ninja Woodfire OO101 pizza oven owners

The Outspark Pizza Stone with Rack is a third-party stone from Outspark for the Ninja Woodfire 8-in-1 outdoor pizza oven, the OO101 and the OO100 series. It pairs a natural cordierite stone with a stainless steel rack, which makes it easier to place the hot stone and set it aside safely.

Outspark promotes good heat retention for crispy crusts and suggests baking breads, cookies, pies and desserts too. Cleaning is a water rinse with no soap. The listing gives a weight of 3 pounds and dimensions of 13 by 12 by 1.5 inches, but it does not say whether those numbers describe the stone, the rack or the set.

This suits OO101 owners who want a light stone and rack. If you want separate stated sizes for stone and rack, the EasiBBQ set is clearer.

The Pizza Stone with Rack for Ninja Woodfire OO101 is made by EasiBBQ, not Ninja. It is designed for the OO100 series and gives clear dimensions: a 12 by 12 inch cordierite stone and a 13.6 by 13.2 inch rack. The rack raises the stone for better hot-air circulation and more even heating.

EasiBBQ describes the cordierite as odorless with excellent thermal shock resistance. Cleaning means scraping off food, letting the stone cool, and washing with warm water or a brush, never soap. The listed weight is 2.91 kg, heavier than the Outspark option, and the listing says the square stone may fit other grills if you measure first.

Pick this for the OO101 when you want exact sizes up front. For sauces and toppings for pizza night, our pizza sauce guide has ideas.

Best for
FlexFlame owners wanting a full kit

The 16 Inch Square Pizza Stone Kit from DcYourHome is a third-party kit for the Ninja FlexFlame grill, with the model field naming the PG300 series. It includes a 16 by 16 inch ceramic stone, a stainless steel peel, a scraper and a cleaning cloth according to the highlight.

It is rated for up to 500°C, listed as 932°F, and DcYourHome suggests it for pizza, bread and even searing steaks or grilling burgers as a griddle-style pan. It weighs 6.44 kg. The listing’s pack count says 3 while the included components list only the stone, so confirm what arrives.

This suits FlexFlame owners who want the tools and a larger square cooking surface in one purchase. The genuine Ninja stone remains the safer fit if you want a part designed alongside the grill.

• 16 by 16 inch square ceramic stone
• Peel, scraper and cloth per highlight
• Rated to 932°F
• Listed for PG300 series

Best for
Woodfire OG800 and OG900 grill owners

The OG900 Pizza Stone with Rack from WEBROIL targets Ninja Woodfire OG800 and OG900 series grills, naming the OG850, OG952, OG901, OG951, OG951RAW and OG901RAW, and the Woodfire Pro Connect XL grill and smoker.

The rectangular cordierite stone measures 14.69 by 9.65 by 0.47 inches, with a 15.12 by 10.24 inch stainless steel rack that has a carrying handle for moving from grill to table. The surface has micro-perforations. It weighs 2.52 kg and is hand wash only.

This is the pick for XL Woodfire grill owners who value the carry handle, since sliding a hot stone out of a grill mid-party is the moment most people burn a hand. It gives way to the Outspark XL stone only if you care about a published heat rating, which WEBROIL does not list.

The Outspark Pizza Stone with Grill Rack fits the Woodfire Pro Connect XL grill and smoker OG850, OG901, OG951 and OG952. The rectangular stone measures 14.69 by 9.65 inches, the same footprint as WEBROIL’s, and comes with a stainless steel rack.

Outspark rates its cordierite for up to 2100°F, the highest heat rating listed here. Cleaning is a water rinse, and it is not dishwasher safe. The listing does not give weight or mention a carrying handle.

Choose this for XL grills if you prefer the higher heat rating. If you also cook indoors, our pressure cooker and air fryer guide covers Ninja’s countertop side.
