The invention provides a surface cover assembly and a cooking utensil. The surface cover assembly is used for the cooking utensil, and comprises a surface cover, a control panel assembly and an inflation hole, wherein the control panel assembly comprises a control panel and an electrical component which are arranged on the surface cover, the control panel hermetically cooperates with the surface cover to enclose a cavity, the electrical component is arranged in the cavity, the inflation hole is formed in the surface cover and communicated with the cavity, the cavity is inflated through the inflation hole to test the gas tightness of the cavity, and after the test ends, the inflation hole is closed. The surface cover assembly and the cooking utensil have the advantages that the control panel hermetically cooperates with the surface cover to enclose the cavity, a gas guide tube of the cooking utensil is utilized to run through the inflation hole to inflate the cavity, if the air pressureinside the closed cavity remains unchanged after a certain period of time, it is guaranteed that the sealing performance of the closed cavity is good, thereby ensuring the safe placement environmentof the control panel assembly, after the test ends, the gas guide tube is taken out and the inflation hole is closed, so that the cavity is still closed space, thereby ensuring the leakproofness of the surface cover assembly.
