Preheat your oven to 350°F (175°C).
Prepare a 9x13-inch baking dish by greasing it with a non-stick spray or butter.
Cut the refrigerated biscuits into quarters and place them in a large bowl.
In a separate bowl, combine the sliced apples, sugar, cinnamon, and pecans (if using).
Fold the apple mixture into the cut biscuits gently until coated.
Pour the melted butter evenly over the biscuit and apple mixture in the baking dish.
Bake in the preheated oven for about 30–35 minutes, or until the biscuits are golden brown and the apples are bubbly.
Remove from the oven and let it cool for a few minutes before serving.
