Creating the Easy Apple Galette is a simple process that will yield delicious results. Follow these easy steps:

1. Prepare the Dough: In a large bowl, mix together the flour, salt, and granulated sugar. Add the chilled butter and mix until the mixture resembles coarse crumbs.
2. Add Ice Water: Gradually add ice water, one tablespoon at a time, mixing until the dough comes together. Avoid overworking the dough.
3. Chill the Dough: Form the dough into a disk, wrap it in plastic wrap, and refrigerate for at least 30 minutes.
4. Preheat the Oven: Preheat your oven to 400°F (200°C).
5. Prepare the Filling: In a bowl, combine the sliced apples, brown sugar, cinnamon, and lemon juice. Toss until the apples are well coated.
6. Roll Out the Dough: On a lightly floured surface, roll the chilled dough into a 12-inch circle. Transfer it to a parchment-lined baking sheet.
7. Assemble the Galette: Place the apple filling in the center of the dough, leaving a 2-inch border. Fold the edges of the dough over the apples, pleating it to create a rustic look.
8. Brush with Egg Wash: Brush the folded edges with the beaten egg and sprinkle extra sugar over the crust.
9. Bake: Bake in the preheated oven for 30-35 minutes, or until the crust is golden brown and the apples are tender.
10. Cool: Allow the galette to cool for 10-15 minutes before slicing.

With these simple steps, you’ll have a stunning Easy Apple Galette ready to be enjoyed!
