Storage: Cover leftover cobbler tightly and refrigerate for up to 4 days. Reheat individual portions in a 350°F oven for 10–15 minutes or microwave briefly. The biscuit topping will soften in the fridge but remains delicious. Freezing: The baked cobbler can be frozen for up to 2 months. Thaw overnight in the refrigerator and reheat in a 350°F oven until warmed through. Fresh vs. Frozen Peaches: Fresh, ripe, in-season peaches are strongly preferred. If using frozen, thaw completely and drain well to avoid a watery filling. If using canned peaches, choose juice-packed (not syrup) and reduce sugar in the filling by half. Make It Lighter: Substitute half the all-purpose flour with whole wheat pastry flour and use coconut sugar in place of brown sugar for a lower-glycemic version with added fiber.
