Bake the galette at 400 degrees for up to an hour or according to the pie crust package directions. At 35 minutes, check to see if the folded 1-inch crust portion is getting too brown. If the apples look like they are getting soft, remove galette from oven and test doneness with a fork. If the edges are getting too brown, fold the excess aluminum foil up over the 1-inch crust and pat down. Otherwise, if all looks good, leave in oven for another 5–10 minutes before checking again.
