Dealing with a pie crust that’s stuck to the pan is frustrating, especially if you’re new to baking pies. A stuck-on crust will destroy the appearance of your pastry. To avoid all that, you may be wondering if you should grease your pie pan. A light spray of non-stick baking spray will keep the crust from sticking to the pan, especially if any filling leaked out onto the pan's surface. You should not use heavy grease because it will affect the texture of your pie crust.
