Preheat oven to 350°F. Butter a baking dish or cast iron skillet.
In a medium bowl, mix together flour, 1/2 cup brown sugar, 1/4 cup sugar, cinnamon, and oats. Using your hands or a pastry cutter, add the softened butter and mix until everything is combined into a crumbly mixture. Set aside.
Place the sliced pears in a large mixing bowl. Add 1/4 cup brown sugar, nutmeg, cinnamon, vanilla, salt, and cornstarch; and stir until the pears are evenly coated.
Pour the pear mixture into the buttered baking dish in an even layer. Sprinkle the topping evenly over the top of the pears.
Bake for 45-50 minutes or until the top is golden brown and the pears are soft.
Let it cool for 10 minutes before serving. Scoop it up and top with ice cream or caramel sauce.
Notes
Don’t slice the pears too thin or they’ll cook down too much. Aim for thicker slices so they stay soft but still hold their shape.
I do not typically peel my pears. This is because it takes extra time, adds nutritional value by leaving on the skins, and I don't mind the texture. Feel free to peel if you desire.
