Many recipes skip this, but it is non-negotiable for the best fries. After you cut your potatoes, you must soak them in cold water.
Why?
Potatoes are packed with starch. When you cut them, that starch is released onto the surface. If you fry them immediately, that surface starch will cause the fries to stick together and absorb too much oil, leading to soggy, greasy results.
Soaking does two critical things:
It washes away the excess surface starch, which is what allows them to become crispy.
It keeps the potatoes from oxidizing and turning brown.
Soak your cut fries for at least 30 minutes, or for truly exceptional results, up to 2 hours. For the ultimate crispness, soak them overnight in the fridge.
Your Step-by-Step Blueprint for Perfect French Fries
This recipe requires a little patience, but the process is straightforward and the payoff is monumental.
Gather Your Ingredients & Tools:
2-3 large Russet or Idaho potatoes (high-starch potatoes are best for fluffy interiors)
2 tablespoons cornstarch
Neutral, high-heat oil for frying (canola, peanut, or vegetable oil)
Salt to taste
Optional Flavor Twists: Garlic powder, smoked paprika, truffle salt, or chopped fresh parsley.
The Method: Patience Leads to Perfection
Cut & Soak: Scrub your potatoes clean. You can peel them or leave the skins on for a rustic feel. Cut them into uniform ¼ to ½-inch sticks. This is crucial for even cooking. Immediately place the cut fries into a large bowl of cold water and soak for as long as you can (minimum 30 minutes).
Dry THOROUGHLY: This is the most critical step after soaking. Drain the fries and pat them completely dry with clean kitchen towels or paper towels. Any surface water will cause the oil to splatter violently and will steam the fries instead of frying them.
The Cornstarch Toss: In a large, dry bowl, toss the completely dried fries with the 2 tablespoons of cornstarch until they are evenly and lightly coated. This is your crisp-making shield.
The First Fry (Blanching): Heat your oil in a heavy-bottomed pot or Dutch oven to 325°F (163°C). Working in batches to avoid overcrowding, fry the potatoes for 4-5 minutes. They will not be brown, but will be soft and slightly translucent. Remove with a slotted spoon and drain on a wire rack set over a baking sheet.
The Cool Down: Let the blanched fries cool completely. You can even do this step ahead of time and let them rest at room temperature for an hour or refrigerate them for later.
The Second Fry (The Crisping): Now, heat your oil to 375°F (190°C). Fry the potatoes again, in batches, for 2-3 minutes, until they are puffed, golden brown, and incredibly crispy.
Season Immediately: Drain the fries on the wire rack (this keeps them from getting soggy versus draining on paper towels) and season immediately with salt and any other seasonings while they're still hot and glistening with oil.

FAQ: Your French Fry Questions, Answered
Can I make these fries in an AIR FRYER?

Russet potatoes are the gold standard. Their high starch and low moisture content is ideal for a fluffy interior.

The first fry cooks the inside. The second fry, at a higher temperature, rapidly crisps the outside, creating the perfect texture contrast.
