Preheat your oven to 375°F (190°C).
In a large bowl, combine flour and sugar for the crust.
Cut in the butter with a pastry cutter or fork until the mixture resembles coarse crumbs.
Gradually add ice water, mixing gently until the dough comes together.
Roll out the dough on a floured surface, then place it in a tart pan.
Arrange apple slices in the crust in a circular pattern.
In a small bowl, mix brown sugar, cinnamon, and nutmeg. Sprinkle over apples.
Bake in the preheated oven for about 45 minutes, or until apples are tender and crust is golden brown.
Allow the tart to cool before slicing and serving.
