A deck oven is a type of baking oven that features one or more flat surfaces, or "decks," where food is placed for cooking. These ovens are commonly used in commercial bakeries and pizzerias because they provide even heat distribution, which is essential for baking bread, pastries, and pizzas. The design allows for multiple trays to be baked simultaneously, increasing efficiency. Deck ovens can be powered by gas or electricity and often have steam injection systems to create a moist baking environment. This moisture helps achieve a crispy crust while keeping the inside soft. Many professional bakers prefer deck ovens for their reliability and consistent results.
