Place corn in the microwave with the husks on. Microwave for 7 minutes then remove to a cutting board using a hot pad or thick kitchen towel. Allow to cool for a few minutes, then cut an inch slice from both ends and peel off the silks and husks. Lie one ear of corn on the cutting board and slice off the kernels (being careful not to cut into the tough center of the cob), rotating the corn as you go. Discard the cob. Repeat for the other two ears of corn. Place sliced corn in a medium-size bowl.
Bake the quiche on the preheated pan (on the lower rack) for 25-30 minutes or until the top is golden and filling is set. Let cool 10 minutes in the pan, then remove from the tart pan and serve. This quiche can be made a day ahead, cooled and refrigerated. Before serving, rewarm in a 325˚F oven for 15-20 minutes.
