Science Behind The Perfect Crust
Par Cooking And Surface Drying
Boiling or microwaving potatoes first removes surface moisture, which prevents steaming and encourages browning. Draining them well ensures the hot oil contacts dry starch for maximum crispness.
High Heat And Proper Oil Choice
An oil with a high smoke point such as avocado, grapeseed, or rice bran allows you to sear without burning. Keeping the pan hot enough creates a crunchy crust while the interior stays soft.
How To Make Restaurant Quality Kenji Roasted Potatoes At Home
Basic Method
Cut potatoes into even pieces, par cook, dry thoroughly, and roast at high temperature with enough fat to coat generously. Stir occasionally to promote even browning and prevent sticking.
Smash And Roast Variation
After par cooking, gently flatten each piece, season, and roast on high heat. The flattened shape increases surface area for more crisp area and deeper flavor.
Custom Flavors And Pairings

Rub with garlic and rosemary for a rustic profile, toss with soy sauce and sesame for an umami rich twist, or finish with smoked paprika and lemon zest for brightness.

FAQ
Reader questions
Do I need a specific type of potato for best results?
Choose starchy potatoes such as Russet or Yukon Gold, which crisp well and develop a fluffy interior. Waxy varieties can be used but will offer a different texture.
Can I make these in an air fryer instead of an oven?
Yes, an air fryer works well by using less oil while still creating a crisp exterior. Shake the basket regularly to promote even cooking and avoid hot spots.
How do I keep the potatoes from sticking to the pan?
Use enough oil to lightly coat the surface, avoid overcrowding the pan, and preheat the vessel so the potatoes sizzle on contact. A well seasoned pan also reduces sticking.
Can I prep the potatoes ahead and roast later?
Par cooking and drying the potatoes up to a day in advance helps with meal prep. Reheat in hot oil or the oven briefly to restore crispness before serving.
