Preheat the oven to 350 degrees F. Butter a 2-quart baking dish.
Heat the butter in a medium skillet set over medium heat. Add the leek and cook, stirring occasionally until soft, 8 to 10 minutes. Add the apples and cook until slightly soft, about 5 minutes. Remove from the heat and transfer to a large bowl.
Add the cornbread, parsley and sage to the leek mixture. Gradually add the broth, stirring gently until the cornbread is well moistened but not soggy. Season with salt and pepper.
Spread out in the prepared baking dish and bake until heated through and lightly browned, about 30 minutes. Sprinkle with parsley before serving.
