Preheat the oven to 375°F (190°C) and line a shallow baking dish with parchment paper.
Slice the pears in half lengthwise and use a melon baller or small spoon to remove the core and seeds to create a small cavity.
Place the pear halves in the prepared baking dish with the cut side facing up.
Distribute the chopped pecans evenly into the hollowed centers of the pears.
Drizzle approximately 1/2 tablespoon of maple syrup over each pear half.
Sprinkle the cinnamon and sea salt evenly across the pears.
Place one small piece of butter on top of each pecan-filled cavity.
Bake for 25 to 30 minutes, or until the pears are tender and the pecans are toasted.
Remove from the oven and spoon any syrup that has collected in the bottom of the dish back over the pears before serving.
