How to Master the Crunch (Crispy Skin Secret) Achieving that restaurant-quality crispy baked potatoes texture requires a few simple techniques: Scrub and Dry Thoroughly: Wash your potatoes well, but make sure to dry them completely with a towel. Moisture is the enemy of crispiness! Coat with Oil: Rub the potato skin with olive oil or melted butter to help it crisp up during baking. A pinch of coarse salt on the outside will create an incredible crust. Bake at High Heat: High temperatures are essential for breaking down moisture and getting that golden crunch.
