Preheat the oven.
Preheat your oven to 375°F (190°C).
Lightly grease a medium baking dish with a little butter or cooking spray.
Prepare the pears.
Wash the pears and slice them in half lengthwise.
Using a small spoon or melon baller, carefully scoop out the cores and seeds, creating a little hollow in the center of each pear half.
Leave the skins on to help the pears hold their shape while baking.
Arrange the pears cut-side up in the prepared baking dish.
Make the brown sugar butter.
In a small bowl, combine the melted butter, brown sugar, cinnamon, vanilla extract, lemon juice, ground ginger, and a pinch of salt.
Stir until everything is well combined.
Coat the pears.
Spoon the brown sugar mixture evenly over the pear halves, making sure some of it settles into the centers.
Don’t worry if a little of the mixture collects at the bottom of the baking dish. It’ll turn into a delicious buttery sauce as the pears bake.
Bake until tender.
Place the baking dish in the oven and bake uncovered for 25–30 minutes.
About halfway through, spoon some of the warm brown sugar sauce from the bottom of the dish over the pears.
The pears are ready when they’re tender enough to pierce easily with a fork.
If your pears are especially firm, they may need another 5–10 minutes.
Toast the pecans.
While the pears are baking, add the chopped pecans to a small dry skillet over medium-low heat.
Toast for 3–5 minutes, stirring frequently, until fragrant and lightly golden.
Remove from the heat and set aside.
Serve warm.
Place two pear halves on each dessert plate.
Spoon some of the warm brown sugar sauce over the pears, then add a scoop of vanilla bean ice cream.
Finish with toasted pecans and an optional drizzle of maple syrup.
Serve while the pears are still warm and the ice cream is just beginning to melt.
