Wood Fired Oven Attachment: Pizzas are ready in 3–5 minutes, with crisp crusts and perfectly browned toppings.
In the June edition of this publication, the Yoder YS640s was reviewed and we mentioned that it is widely regarded as one of the highest-quality pellet grills on the market, particularly for serious backyard pitmasters and even some commercial applications.
The 335-pound grill is made of heavy-duty steel and also built in the United States. They are built in Kansas, which allows for better quality control compared to many imported competitors.
The Yoder YS640s is often considered a tank of a smoker — built for longevity, performance, and consistent results. This smoker is ideal for serious BBQ enthusiasts who want pro-level equipment that lasts decades with proper care.
In our opinion, a must have accessory is the wood fired oven insert which retails for $489. It is a handcrafted attachment for Yoder YS480/YS640 or YS1500 pellet grills, offering restaurant‑style results with push‑button convenience.
In our tests of cooking pizza, it achieved a temperature of 700°F at the cooking stone, while the hood top reached up to 900°F, which was ideal for cooking quick pizzas. We also used the oven attachment to cook a baked ziti which produced the crusty cheese on the top making a delicious Italian meal for the whole family.

Must Have Accessory: The wood fired oven attachment is built with heavy-duty powder‑coated steel and a perforated heat diffuser.
The wood fired oven attachment is built with heavy-duty powder‑coated steel and a perforated heat diffuser for balanced, radiant heat distribution from top and bottom at the same time. It incorporates a 3/4” American-made, kiln-fired cooking stone engineered for rapid heat transfer and near-instant recovery.
Pizzas are ready in 3–5 minutes, with crisp crusts and perfectly browned toppings. The wood fired oven is also excellent for baking (bread, pies, casseroles) and broiling (lasagna, mac & cheese) thanks to superior radiant browning.
The flat oven top can be used as an additional high-temp cooking surface for cast iron or carbon steel cookware. This is ideal for cooking sauce on top to achieve an elevated flavor profile.
This wood fired oven is perfect for yard space conservation as it turns a pellet grill into a full-fledged wood‑fired oven where no separate standalone oven is needed. It produces authentic wood-fired flavor and high-heat performance using just pellets, without wood logs or splitting.
