Pre-heat oven to 400 Degrees F.
Using a food processor, hand mixer, or blender, combine all ingredients for the cream cheese filling. Blend until smooth.
8 ounces cream cheese, 1 egg, ¼ cup sugar, ½ teaspoon almond extract, 1 teaspoon vanilla extract, Zest of 1 lemon
Place a sheet of parchment on a sheet pan, and roll out puff pastry on the parchment. Spread the cream cheese filling down the center of the puff pastry leaving about 1 ½ inches around the edge for folding over. Place sheet pan in the freezer to firm the pastry up, while preparing the peaches.
1 sheet puff pastry
Slice peaches in half, and remove pits. Evenly slice the peaches. Set aside in bowl, and splash with half the lemon to keep them bright.
3 peaches
Bring the puff pastry out of the freezer, and working quickly, arrange the peaches in 3 rows on top of the cream cheese filling, overlapping the peach slices.
Now it is time to wrap the puff pastry inward toward the peaches. Do this by starting on one edge and just pull crust in and continue around the entire outside.
Brush edge of crust with egg, and sprinkle the crust with the course sugar. Now add the sugar over the top.
Pop this into the oven. Bake for 20-30 minutes. Spin around at 10 minute intervals. Since ovens vary, watch for a golden crust.
Allow galette to cool for at least 30 minutes. May serve warm, or room temperature. Store in the fridge wrapped, for up to 1 week.
