French fries are potato batons fried until crisp outside and fluffy inside, a popular side with roots in Belgian and French food traditions. This deep-fryer method uses two batches of frying at different temperatures: a gentler first cook softens the centers, and a hotter second cook makes the fries golden and crisp.
Ingredients
- 2 lb (900 g) russet potatoes, about 4 medium
- 8 cups (1.9 L) cold water, for soaking
- 8 cups (1.9 L) neutral high-smoke-point frying oil, such as canola, peanut, or sunflower oil, or enough to fill your fryer to its marked maximum line
- 1 tsp (6 g) fine salt, or to taste
Instructions
- Cut the potatoes. Scrub the potatoes and peel them if you prefer; leaving the skins on is fine after a thorough scrub. Cut them into even batons about ¼ inch (6 mm) thick. Consistent pieces cook at the same rate. Put the cut potatoes straight into a bowl of cold water.
- Rinse and soak. Swish the potatoes in the water, drain, and cover with fresh cold water. Soak for 30 minutes to remove excess surface starch, which helps the fries separate and crisp. Drain well. Pat the batons thoroughly dry with clean towels; water on potatoes can cause hot oil to splatter.
- Prepare the fryer. Add oil only up to the fryer’s maximum-fill mark, following the appliance instructions. Heat it to 325°F (163°C). Keep the fryer on a stable, heat-resistant surface, away from water, and do not leave hot oil unattended. Never add water to hot oil or overfill the basket.
- First fry. Divide the potatoes into batches small enough to sit loosely in the basket; crowding lowers the oil temperature and leads to greasy fries. Lower one batch carefully into the oil and fry for 4–5 minutes, until softened and pale, not browned. Lift the basket and let the fries drain over the fryer. Transfer them to a wire rack set over a tray while you cook the remaining batches. Let the oil return to 325°F (163°C) between batches.
- Heat the oil for the second fry. Once all the batches have had their first fry, increase the oil temperature to 375°F (191°C). Allow the oil to reach temperature before continuing.
- Fry until golden. Return the potatoes to the oil in batches and fry for 2–4 minutes, until evenly golden and crisp. The exact time depends on the potato thickness and fryer. Drain each batch on the rack, rather than piling the fries on paper towels, so steam can escape.
- Season and serve. Sprinkle the hot fries with salt and serve promptly. Let the oil cool completely before handling or filtering it; follow your fryer’s instructions for oil disposal or storage.
Tips
- Dry thoroughly: Even a little water on the potatoes can make hot oil spit. After draining, blot them well and check that no water remains in the bowl or basket.
- Use a thermometer if needed: A fryer with a reliable thermostat is easiest. If yours runs hot or cold, check the oil with a deep-fry thermometer and adjust the controls. The temperature will dip when potatoes go in, so fry in manageable batches.
- Choose the right potato: Russets have a starchy, fluffy interior and work especially well. Yukon Gold potatoes can be used, but their fries tend to be creamier and less fluffy.
- Season while hot: Salt sticks best just after frying. Avoid salting the raw potatoes before frying, as it draws out moisture and can interfere with crisping.
Serving Suggestions
Serve the fries right away as a side for burgers, sandwiches, fried fish, or grilled vegetables. They pair well with ketchup, mayonnaise, garlic mayonnaise, or vinegar; offer sauces in small bowls so the fries stay crisp until dipped. For a simple shareable snack, bring the fries to the table in a wide, shallow dish rather than a deep bowl, which traps steam.
Variations
Herb fries: Toss the hot fries with a little finely chopped parsley and a pinch of garlic powder along with the salt. Use dry seasonings sparingly so they do not overwhelm the potatoes.
Spiced fries: Mix the salt with smoked paprika, black pepper, or a small pinch of cayenne, then season immediately after frying. For a cheesy finish, add finely grated Parmesan while the fries are hot.
Thicker-cut fries: Cut the potatoes into ⅜-inch (1 cm) batons. They will need longer in both frying stages; use the color and texture cues rather than relying on the listed times alone. The centers will be more substantial and the exterior less delicate.
Storage and Reheating
French fries are best fresh. Refrigerate leftovers within 2 hours in a shallow airtight container and use within 3–4 days. They will soften in the refrigerator, so do not expect them to retain their original texture. For longer storage, freeze the cooled fries in a single layer, then transfer them to a freezer-safe bag; use within about 2 months for best quality.
Reheat refrigerated or frozen fries in a single layer in an air fryer at 375°F (191°C) for 3–6 minutes, or in a 425°F (218°C) oven for about 8–12 minutes, turning once. Frozen fries may need several extra minutes. Reheat until steaming hot throughout; discard fries left at room temperature for more than 2 hours.
Frequently Asked Questions
Why soak potatoes before frying?
Soaking loosens excess starch on the cut surfaces, helping fries cook more evenly and stick together less. Drain and dry them thoroughly afterward; wet potatoes are unsafe to lower into hot oil.
Can I fry the potatoes just once?
You can, but the two-stage method gives a tender interior and crisp exterior more reliably. A single fry may brown the outside before thicker pieces are cooked through, and the texture is usually less crisp as the fries cool.
Why are my fries soggy?
Common causes include damp potatoes, overcrowding the basket, oil below the target temperature, and stacking finished fries so steam is trapped. Dry the potatoes, cook in small batches, let the oil recover between batches, and drain fries on a rack.
Can I use a different oil?
Yes. Choose a neutral oil suitable for deep frying, such as canola, peanut, or sunflower oil, and check your fryer’s manual for any oil restrictions. Do not fill above the appliance’s maximum line.
Can I make the first fry ahead?
Yes. After the first fry, spread the potatoes on a rack and let them cool. Refrigerate them promptly in a covered container and finish the second fry within 24 hours. Bring the oil to 375°F (191°C) before frying, and work in batches.
How do I dispose of the frying oil?
Let it cool completely, then follow local guidance and the fryer manufacturer’s instructions. Do not pour oil down a sink or drain. If reusing oil, strain it only after it has cooled and store it covered according to the appliance guidance; discard it if it smells rancid, looks unusually dark, or foams excessively.
