A cooking system includes a housing having a hollow interior, a heating element operable to heat to said hollow interior, a food support surface arranged within said hollow interior, and a combustible substrate module removably positionable in said housing. When positioned in the housing, the combustible substrate module is arranged in fluid communication with the hollow interior and the combustible substrate module is disposed remote of the food support surface.

An example oven can include: a main body defining a cooking cavity; a front portion of the main body defining a front opening for receiving a food item and acting as an air vent; a baking stone positioned to support the food item; a tray assembly including a grate positioned in the main body; and a gas burner positioned adjacent to the baking stone and the tray assembly; wherein the gas burner is configured to combust a gas to heat the cooking cavity; wherein the gas burner is positioned to ignite fuel on the grate of the tray assembly to further heat the cooking cavity; and wherein the gas burner is positioned to heat at least a portion of the baking stone.

Disclosed is an oven comprising: an oven housing defining an oven chamber for containing foodstuffs during cooking or curing; and an oven floor forming a base of the oven chamber for supporting foodstuffs to be cooked or cured in the oven chamber, wherein the oven floor comprises: a first aperture for communication with a non-gas-fuel energy source for cooking or curing foodstuffs in the oven chamber; and a second aperture for communication with a gas-fuel energy source for cooking or curing foodstuffs in the oven chamber.

An oven appliance includes a cabinet with a chamber is defined within the cabinet for receipt of food items for cooking. The oven appliance also includes a gas burner positioned proximate to a bottom portion and/or a back wall of the chamber. A natural convection flow path is defined through the chamber. The natural convection flow path extends from an origin at the gas burner to a top wall of the chamber. The oven appliance further includes a convection fan positioned along the natural convection flow path above the gas burner and below the top wall. The convection fan is positioned and configured to divert combustion products generated by the gas burner from the natural convection flow path along a forced convection flow path towards a center of the chamber when the convection fan is activated.

An oven appliance includes a cabinet. A chamber is defined within the cabinet for receipt of food items for cooking. The oven appliance also includes a gas burner positioned proximate to a bottom portion of the chamber with a combustion products guide structure positioned and oriented to guide combustion products from the gas burner to an outlet proximate a back wall of the chamber.

A method of operating an oven appliance includes obtaining a temperature set point, determining, based on the temperature set point, an electric heating temperature range and a gas undershoot temperature limit, the gas undershoot limit being below the electric heating temperature range, determining that a chamber temperature of the oven appliance has dropped to the gas undershoot temperature limit, and operating a gas heat source to maintain the chamber temperature above the gas undershoot temperature limit.

An oven appliance includes a cabinet with a chamber for receipt of food items for cooking defined therein. The oven appliance also includes a gas burner positioned proximate to a top portion of the chamber. The oven appliance may also include a low-power electric heating element. The gas burner may be the only combustive heat source for the chamber. The oven appliance includes an electric power supply that may consist of a twenty amp or less circuit.
