Step One: Mix Flour, Sugar and Salt
Using a food processor, mix the flour, sugar, and salt.
Step Two: Whisk Egg and Cream Together
In a measuring cup, lightly whisk an egg. Add enough heavy cream to the egg to equal 1/3 cup. Lightly whisk the egg and heavy cream together.
Step Three: Add Butter to Flour Mix
Using a food processor, pulse the butter and flour mix together. Combine until the dough reaches chickpea size pieces. Drizzle approximately ¼ cup of egg mixture onto to dough. Stir until dough forms large crumbs and add lemon zest if desired.
Step Four: Form a Disk Shape with the Dough
Sprinkle flour down your countertop and place dough on it. Pat the dough together until it forms a disk shape. Wrap the dough in plastic and store in the fridge for at least two hours or up to three days.
Step Five: Roll Dough to 12-inch Round Form
Using a rolling pin, roll the dough out to a 12-inch round. Add parchment paper to a round baking sheet and add dough, then return to the fridge while making the filling. Preheat the oven to 400 degrees Fahrenheit.
Step Six: Prepare Peaches
Allow the peaches to partially thaw. Toss them with a pinch of salt, lemon juice, lemon zest, cornstarch and all but one tablespoon of sugar.
Step Seven: Add Peaches to Dough
Add the peach mixture to the dough, leaving a 1 ½ inch border. Carefully fold the pastry to cover the fruit, creating a pleat to hold it in.
Step Nine: Add Remaining Cream and Egg Mixture
Brush the remaining cream and egg mixture on the pastry and sprinkle the crust with the remaining sugar.
Step Ten: Bake the Galette
Bake the galette for 35-45 minutes, until filling is bubbling, and the crust is golden brown. Cool for at least 20 minutes before serving.
This beautiful peach galette combines delicious golden pastry with sweet juicy peaches. Pair this with some vanilla ice cream to have a scrumptious dessert perfect for any time of the year.
