Step 1

Heat a 10-inch cast iron skillet in the oven while you preheat the oven to 450°F.

Step 2

In a large bowl, whisk or stir together the cornmeal, eggs, buttermilk, and melted butter. Stir just until combined; do not over-mix.

Step 3

Carefully remove the hot skillet from the oven. Add the oil to the hot skillet; spread to coat on the bottom and sides (I use a pastry brush for this).

Step 4

Pour the batter into the greased skillet.

Step 5

Bake until golden brown on top and a toothpick inserted in the center of the cornbread comes out clean, about 15 minutes.
