Soak your cut potatoes in cold water for at least 30 minutes. This washes out excess starch, which prevents them from sticking together. Dry them thoroughly—any water in the oil is a sputtering disaster.
Use a neutral oil like peanut, canola, or sunflower. These have high smoke points (above 400°F), so they won’t burn before your fries are done. Olive oil is a no-go here; it’s too delicate.
After the first fry, let them cool completely on a wire rack. You can even chill them in the fridge for an hour. This “rest” lets moisture redistribute, making the second fry even crispier.
Season immediately after the second fry while the oil is still hot. Salt will stick better, and the heat helps herbs like rosemary or thyme bloom. A dash of vinegar powder or smoked paprika can elevate them to legend status.

Not all fries are created equal. Shoestrings demand a slightly higher initial temp (335°F) because they cook so fast. Thicker steak fries need a longer first fry, around 12 minutes at 325°F, to fully cook the interior.

Sweet potatoes behave differently. Their high sugar content makes them burn easily, so drop the second fry to 350°F and watch like a hawk. Aim for a light amber color, not dark brown.
Frozen fries? Skip the thaw. Drop them straight from the freezer into 350°F oil. The ice crystals on the surface actually help create an extra-crispy shell. Just don’t crowd the basket.
For a real treat, finish your fries with a sprinkle of malt vinegar and a pinch of sea salt. The acidity cuts the richness, while the salt amplifies the crunch. It’s a simple, perfect balance.
