Preheat oven to 350°F. Grease a deep 8-inch or 9-inch square or round baking dish, or a 10-inch cast iron skillet. Set aside. Place the apple slices in a large bowl.
In a medium bowl, whisk together the melted butter, brown sugar, granulated sugar, lemon juice, cornstarch, cinnamon, cloves, ginger, nutmeg and salt.
Pour the butter mixture over the apples; toss to coat.
Transfer the apples and any extra sauce from the bottom of the bowl to the prepared dish.
Bake, uncovered, for about 25 minutes, or until the apples are fork-tender but not mushy. Give them a good stir to coat in the sauce, then serve warm.
