The invention provides a steam valve and a cooking utensil. The steam valve includes a valve base, a valve cover and a grid, the valve cover covers the valve base and is connected with the valve baseto define a steam cavity, and the top wall of the valve cover is provided with reinforcing ribs; the grid is located in the steam cavity and supported between the valve cover and the valve base and isa plastic grid. According to the steam valve, by additionally arranging the reinforcing ribs on the valve cover of the steam valve, the strength of the valve cover is effectively improved, and the situation is prevented that the valve cover is deformed in the working process due to too high temperature; the grid is supported between the valve cover and the valve base and has a good function of supporting the valve cover, and the situation is further effectively prevented that the valve cover is deformed after heated, especially under the condition that for large steam valves, along with the increase of the size of valve covers, the strength of the valve covers can be reduced and the valve covers are easy to deform after heated; by arranging the reinforcing ribs on the valve cover and supporting the grid between the valve cover and the valve base, the effect of preventing the valve cover from heated deformation is more obvious.
