Extra Crispy Double-Fried French Fries
The ultimate golden French fries with an ultra-crispy exterior and tender interior, achieved through a classic blanching, starch-washing, and double-frying technique.
Making restaurant-quality French fries at home requires more than just slicing and frying potatoes. By rinsing away excess surface starch, blanching to set the interior texture, and utilizing a crucial double-fry method at precise temperatures, you can achieve the ultimate crunch without specialized equipment.
Ingredients
- 4 large russet potatoes
- 2 tbsp cornstarch
- 1 tbsp all-purpose flour
- 1 tsp salt
- 1 L cooking oil for frying
Instructions
- 1Cut the Potatoes into Sticks

Place the peeled potatoes on a cutting board and use a cleaver to slice them into uniform sticks. Uniform sizing ensures they cook evenly during blanching and frying.
Tip: Keep the potato sticks consistent in thickness so they fry at the same rate. - 2Wash Away Excess Starch

Place the cut potato sticks into a large metal bowl and wash them thoroughly under running tap water. Agitate the potatoes with your hands to rinse off surface starch, which helps prevent them from burning or sticking together later.
Tip: Rinsing until the water runs clear is key to achieving an extra-crispy exterior. - 3Blanch the Potato Sticks

Transfer the washed potato sticks into a wok or pot of boiling water. Let them cook briefly to partially soften the interior while locking in their shape before frying.
Tip: Do not over-boil; they should remain firm enough to hold together when drained. - 4Shock in Cold Water

Use a slotted spoon or strainer to scoop the blanched potato sticks out of the boiling water and immediately transfer them into a bowl of cold water. This halts the cooking process instantly and firms up the texture.
Tip: Ice water can be used to speed up the cooling process and make them extra crisp. - 5Dry and Season the Potatoes

Drain the potato sticks and place them back into the metal bowl. Use paper towels to thoroughly pat away any remaining moisture on the surface, then sprinkle a small amount of salt over them.
Tip: Removing excess surface moisture is essential so the coating adheres properly and oil does not splatter. - 6Mix Coating Flours

In a clear glass bowl, combine cornstarch and regular flour in a 2:1 ratio. Use chopsticks to mix them thoroughly together until fully blended.
Tip: The cornstarch-heavy blend creates a light, crispy crust, while the flour adds structure. - 7Coat potato sticks in flour

Add the flour mixture directly to the prepped potato sticks, cover the bowl securely, and toss them thoroughly by shaking to coat each piece evenly.
Tip: Make sure the bowl is tightly sealed with a lid before shaking to prevent flour from spilling out. - 8First fry the coated potatoes

Carefully drop the coated potato sticks into a wok filled with hot oil and gently stir them to prevent sticking while they undergo their initial frying process.
Tip: Do not overcrowd the wok; fry in batches if necessary to maintain the oil temperature. - 9Refry for extra crispiness

Transfer the partially fried potato sticks back into hotter oil to refry them until they turn a rich golden brown and achieve maximum crispiness on the outside.
Tip: Ensure the oil is extra hot before the second fry to lock in the crunch without absorbing excess oil.
