You’ll get the best French fries by frying in two stages: first around 325°F, then around 375°F.

Quick Scoop

  • Aim for an oil range of 325°F–375°F (about 160°C–190°C) for classic fries.
  • Use a high‑heat oil (like canola, peanut, or sunflower) and a deep, heavy pot for safety and even heating.
  • Always work in small batches so the oil temperature doesn’t crash, or your fries will turn greasy instead of crisp.

Two‑Stage Frying (Restaurant‑Style)

  1. Prep the potatoes
    • Cut potatoes into even sticks, about 1/4–1/3 inch thick, and rinse or soak briefly to remove excess surface starch, which helps with crispiness.
 * Dry them very well with towels so they don’t splatter in the hot oil.
  1. First fry: cook through
    • Heat oil to about 325°F / 163°C.
 * Add a small batch of fries and cook 5–6 minutes, until they’re tender but very pale and not yet crisp.

 * Remove and drain on a rack or paper towels; let them cool and steam off moisture.
  1. Second fry: crisp and color
    • Raise oil to about 375°F / 190°C.
 * Fry the blanched fries again for 1–3 minutes, until golden and crisp outside and fluffy inside.

 * Drain, then salt immediately while still hot so the seasoning sticks well.

Why this temp range works

  • Around 325°F , the potatoes cook through without browning too fast, giving you a soft interior.
  • Around 375°F , the outside dehydrates quickly and browns, creating that shatter‑crisp shell while limiting oil absorption.
  • Below about 325°F, fries soak up more oil and stay soggy; above about 375°F, they brown or burn before the center cooks.

Simple One‑Fry Option

If you want to skip the full two‑stage method:

  • Heat oil to about 350°F–365°F (175°C–185°C) , then fry in small batches until cooked through and golden, 6–9 minutes depending on thickness.
  • This is easier but usually a bit less perfectly crisp than the classic double‑fry, especially if you want fries that stay crisp for a long time (like for a party or game night).

Safety & Little Pro Tips

  • Use a thermometer clipped to the pot to keep the oil in the right zone; big temp swings give uneven fries.
  • Leave several centimeters (a couple inches) of empty space above the oil because it will bubble up when you add potatoes.
  • Don’t crowd the pot—if the sizzle dies down a lot when you add fries, the batch is too big.

For that “bistro” or fast‑food style fry at home, think: cook low at 325°F, crisp high at 375°F, and never rush the oil back up between batches.
