Make crisp French Fries Recipe at home with a double-fry method for golden, fluffy fries.
Fill a large clear glass bowl with very cold water and a generous handful of ice cubes; if you like, stir in a tablespoon of distilled white vinegar to help the fries hold their crisp. This ice bath is the first active step — it stabilizes temperature and begins extracting surface starch immediately, so have the bowl ready on the quartz surface before you move on.
Thoroughly scrub each russet under cold running water, peeling them only if you prefer the classic smooth fry; leaving skins on gives a rustic texture. Trim off any eyes or blemishes and set whole, cleaned potatoes next to a small ramekin holding kosher salt and a little bowl with the optional grated Parmesan and chopped parsley for later.
Slice each potato lengthwise into consistent 1/4-inch (6 mm) slabs, stack and cut into uniform 1/4-inch sticks. As soon as each baton is cut, drop them straight into the prepared ice-cold glass bowl so they stay crisp and don’t brown; the visual result should be a dense bed of pale, raw potato sticks bobbing in icy water with tiny beads of condensation on the bowl.

Let the batons rest in the ice water for at least 30 minutes (up to 2 hours) in the refrigerator to leach starch and firm the centers. When soaking is complete, pour the contents into a stainless-steel colander and rinse under cold running water until the rinse water runs mostly clear; the visual milestone is the transformation from cloudy starchy water to mostly clear, and the batons looking noticeably less opaque.

Spread the drained potatoes in a single layer on a clean kitchen towel or several layers of paper towels and pat them absolutely dry — removing surface moisture is critical to avoid dangerous oil splatter and to get a proper crisp. The result is matte, residue-free potato sticks arranged in a single layer, ready for frying.
Blanch small batches in preheated oil held at the lower blanching temperature until the fries are softened, slightly swollen, and pale — they should bend without breaking. Lift them out and transfer to a wire rack set over paper towels to drain and cool; the visual cue is a stack of pale, plump fries that look cooked through but not yet golden. Allow them to rest at room temperature for at least 15 minutes before moving on.

Heat the oil to the higher finishing temperature and fry the cooled, blanched batons in small batches until they blister and turn a deep golden-brown with a textured, crackly crust. Drain on a clean wire rack, immediately toss with kosher salt and the optional seasoning blend so it adheres while the fries are hottest — visually they should read as intensely golden, slightly blistered surfaces with visible salt crystals and a dusting of paprika or grated Parmesan if used.

Transfer the finished fries to a shallow matte charcoal ceramic platter or a wide, shallow serving bowl, scatter finely chopped parsley and a light shower of freshly grated Parmesan if desired, and place a small dipping ramekin of ketchup or mayonnaise beside the pile. Serve immediately while the contrast between the crisp exterior and fluffy interior is most pronounced.
