Place corn on a rimmed baking sheet that is lined with tin foil (for easier cleanup). Drizzle with olive oil and salt and pepper. Broil in the oven 15-20 minutes, or until corn kernels begin to char. Check every few minutes and use a set of tongs to turn the ears of corn as needed. Remove from the oven and let cool. Use a knife to carefully cut the kernels away from the cob. I like to stand each ear up on its end in a large bowl, I hold onto the top of the ear of corn, and use a knife to slice the kernels away - that way my fingers are safe and the kernels fall into the bowl, rather than fly all over the counter.
