Straight cut french fries are the classic, no-nonsense version of the beloved fast-food side: crisp golden batons of potato with a fluffy interior, perfect for dipping. This recipe delivers that ideal texture by using a double-fry method—first cooking the potatoes at a lower temperature to soften them, then frying again at high heat for a crunchy crust. It’s a simple, foolproof technique that works with just a few ingredients and a standard kitchen pot.
Ingredients
- 4 large russet potatoes (about 2 lb / 900 g), scrubbed
- 1 tbsp white vinegar (optional, for soaking)
- 2 qt (1.9 L) vegetable or peanut oil, for frying
- Kosher salt, to taste
Instructions
- Cut the potatoes into 1/4-inch (6 mm) thick sticks. Keep them uniform so they cook evenly. Place the cut potatoes in a large bowl of cold water with the vinegar (if using) and soak for at least 30 minutes, or up to 2 hours. This removes excess starch and helps them crisp up.
- Drain the potatoes and pat them thoroughly dry with a clean kitchen towel or paper towels. Any moisture can cause the oil to splatter.
- In a large heavy-bottomed pot (like a Dutch oven), heat the oil to 325°F (163°C) over medium heat. Use a deep-fry thermometer for accuracy.
- Working in batches to avoid crowding, fry the potatoes for 4-5 minutes, until they are soft and just starting to color. They should not be brown. Remove with a slotted spoon and drain on a paper towel-lined baking sheet. Let them cool for at least 10 minutes. This is the first fry.
- Increase the oil temperature to 375°F (190°C). Fry the potatoes again, in batches, for 2-3 minutes, until golden brown and crispy. Drain on fresh paper towels.
- Immediately sprinkle with salt while hot. Serve right away.
Tips
- Potato choice: Russets are best for their high starch and low moisture, which yields fluffy interiors. Yukon Golds will work but result in a denser fry.
- Soaking: Don’t skip the water soak—it draws out surface starch that can make fries gummy. The vinegar helps maintain the potato’s structure and prevents them from falling apart.
- Double frying: The first fry cooks the potato through; the second fry creates the crispy crust. If you skip the first fry, you’ll get soggy fries.
- Common mistake: Overcrowding the pot drops the oil temperature, making fries greasy. Fry in small batches and let the oil return to temperature between batches.
Serving Suggestions
Serve these fries hot with classic condiments like ketchup, mayonnaise, or malt vinegar. They also pair beautifully with burgers, fried fish, or a simple steak. For a loaded version, top with melted cheese, bacon bits, and green onions.
Variations
- Seasoned fries: Toss the hot fries with garlic powder, paprika, or a pinch of cayenne along with salt.
- Herb fries: Add chopped fresh parsley or rosemary to the salt before sprinkling.
- Sweet potato fries: Substitute sweet potatoes, but note they cook faster—reduce the first fry to 3-4 minutes and the second to 2 minutes.
- Baked version: For a lighter take, toss the cut potatoes with 2 tbsp (30 ml) oil and bake at 425°F (218°C) for 25-30 minutes, flipping once, until crispy.
Storage and Reheating
Leftover fries can be refrigerated in an airtight container for up to 3 days. To reheat, spread them on a baking sheet and warm in a 400°F (204°C) oven for 5-7 minutes until crisp. Avoid microwaving, as it makes them soggy. For longer storage, freeze the cooked fries (after the first fry) in a single layer, then transfer to a freezer bag for up to 3 months. Fry from frozen at 375°F (190°C) for 3-4 minutes.
Frequently Asked Questions
Why are my fries not crispy? The most common reasons are not soaking the potatoes long enough, not drying them thoroughly before frying, or overcrowding the pot. Ensure the oil is at the correct temperature and fry in small batches.
Can I use olive oil for frying? Olive oil has a lower smoke point, so it can burn at the high temperatures needed for frying. Use a neutral oil with a high smoke point like vegetable, canola, or peanut oil.
How do I know when the oil is at the right temperature without a thermometer? You can test by dropping a small piece of potato into the oil. If it sizzles immediately and rises to the surface, the oil is ready. For precise results, a thermometer is recommended.
Can I make these fries ahead of time? Yes, you can do the first fry up to 2 hours ahead and keep the potatoes at room temperature. Complete the second fry just before serving for the best texture.
Do I need to peel the potatoes? No, leaving the skin on adds texture and nutrients. Just scrub them well. If you prefer skinless fries, peel before cutting.
What is the best way to cut straight fries? Use a sharp chef’s knife and a stable cutting board. Cut a thin slice off one side of the potato to create a flat surface, then cut into planks and then into sticks. A mandoline or fry cutter can speed up the process.
