When the heat is on, the water vapor mixes with the hot air that comes up on the side of the pot, directly from the flames. That prevents it from quickly condensing into water droplets (steam). When the stove is turned off the vapor comes into contact with the cold outside air, and that creates condensation.

Steam is formed when water vapour condenses to form tiny droplets of water.

When the stove is on, there is a constant inflow of hot water vapour above the container, which prevents condensation of water to form steam. But when the stove is turned off, the inflow of vapour stops, the vapour condenses and there is a sudden gush of steam above the container.
