Step 1

Preheat the oven to 350 degrees F. Coat a 3-quart baking dish with cooking spray.

Step 2

Cut the corn kernels from the cobs (about 8 cups) and scrape the cobs to remove all the liquid. Melt the butter in a large skillet over medium heat. Add the corn, milk, salt and pepper. Simmer until the corn is softened and the mixture begins to thicken, about 5 minutes. Remove from the heat.

Step 3

Stir together the cornbread mix, sour cream, eggs and half of the cheese in a bowl. Stir in the creamed corn. Pour the mixture into the prepared dish. Sprinkle with the remaining cheese. Bake until the casserole is browned and set, 35 to 40 minutes. Sprinkle with the green onions before serving, if desired.
