This easy peach crisp features juicy peaches beneath a crunchy oatmeal streusel topping that stays crisp after baking, making it a perfect summer dessert that’s quick and simple to prepare.
Keep butter cold to ensure a crumbly, flaky streusel topping. Do not overmix the topping to keep it light and crunchy. Use cornstarch to thicken the peach juices for a clear, glossy sauce. If peaches are very juicy, add an extra tablespoon of cornstarch. Lemon juice brightens the peach flavor and should not be skipped. Set a timer to avoid burning the topping. For gluten-free, substitute all-purpose flour with almond or gluten-free flour. For dairy-free, use coconut oil instead of butter.
