Choosing the Right Potatoes
What Makes a Potato Ideal for French Fries?
The foundation of crispy French fries begins with selecting the right type of potato. Not all potatoes are created equal when it comes to frying; some are better suited for baking or mashing. For fries, the ideal potato should have a high starch content and low moisture. This combination helps achieve a crispy exterior while maintaining a fluffy interior.
Best Potato Varieties for French Fries
- Russet Potatoes: Also known as Idaho potatoes, they are the most popular choice for crispy fries due to their high starch and low moisture content.
- Yukon Gold: Slightly waxier but still excellent for fries, offering a buttery flavor and good texture.
- Maris Piper: Commonly used in the UK, they produce fluffy and crispy fries.
Preparing the Potatoes
Peeling and Cutting
Start by peeling the potatoes if you prefer skinless fries. If you like the skin, wash thoroughly to remove dirt. Cut the potatoes into your desired shape—straight, crinkle, or shoestring—ensuring uniform size for even cooking.
Soaking the Potatoes
One of the most crucial steps in making the crispiest fries is soaking the cut potatoes. Soaking removes excess surface starch, which can cause fries to stick together or become soggy.
- Place the cut potatoes into a large bowl of cold water.
- Soak for at least 30 minutes, or up to 2 hours for optimal starch removal.
- Drain and rinse the potatoes thoroughly to wash away residual starch.
- Pat dry completely with a clean towel or paper towels. Excess moisture can hinder crispiness during frying.
Choosing the Right Oil and Temperature
Best Oils for Frying
Select oils with high smoke points to prevent burning and impart a neutral flavor:
- Peanut oil
- Canola oil
- Vegetable oil
- Sunflower oil
- Refined avocado oil (optional but excellent)
Optimal Frying Temperatures
Achieving crispy fries involves frying at the right temperature:
- First fry (blanching): 275°F (135°C) — This cooks the interior without browning too much.
- Second fry (crisping): 375°F (190°C) — This is where the exterior crisps up beautifully.
Use a reliable thermometer to monitor oil temperature; fluctuations can lead to soggy or burnt fries.
The Double Frying Technique
Why Double Fry?
Double frying is the secret to achieving that coveted crunch. The first fry cooks the potato on a low heat, allowing it to become tender inside. The second fry at a higher temperature crisps up the exterior, creating that irresistible crunch.
Step-by-Step Double Frying Process
- Heat oil to 275°F (135°C).
- Fry the prepared potatoes in batches to avoid overcrowding. Cook for about 3-4 minutes until they are soft and pale. Do not brown yet.
- Remove the fries from the oil and drain on paper towels. Let them rest for at least 10 minutes or up to an hour. Resting helps moisture escape, leading to crispier fries.
- Increase the oil temperature to 375°F (190°C).
- Fry the potatoes a second time for 2-3 minutes until golden brown and crispy.
- Transfer to a paper towel-lined plate to drain excess oil. Season immediately.
Seasoning and Serving
Perfect Seasoning Tips
For the best flavor, season your fries immediately after the second fry while they are still hot:
- Classic salt
- Garlic powder
- Paprika
- Black pepper
- Parmesan cheese (for a savory twist)
- Fresh herbs like parsley
Experiment with seasoning blends to find your favorite flavor profile.
Additional Tips for Extra Crispy Fries
- Use a light coating of cornstarch or rice flour before frying for an extra crispy crust.
- Avoid overcrowding the fryer; cook in batches.
- Keep the fries warm in an oven set to low heat if making in advance.
- Serve immediately for maximum crispiness, as fries tend to lose crunch over time.
Alternative Methods to Achieve Crispy Fries
Oven-Baked Crispy Fries
If you prefer baking, follow these steps:
- Toss cut potatoes with a small amount of oil and cornstarch.
- Spread evenly on a baking sheet lined with parchment paper.
- Bake at 425°F (220°C) for 25-30 minutes, flipping halfway.
- For extra crispiness, broil for the last 2-3 minutes.
Air-Fryer French Fries
An air fryer can produce crispy fries with less oil:
- Toss potatoes with a tablespoon of oil and seasonings.
- Cook at 400°F (200°C) for 15-20 minutes, shaking halfway through.
- Check for doneness and crispiness.
Final Tips for the Crispiest French Fries
- Always dry potatoes thoroughly before frying.
- Use fresh, high-quality oil.
- Maintain consistent frying temperatures.
- Don't overload the frying vessel.
- Serve immediately for optimal crunch.

Frequently Asked Questions
What is the key to making the crispiest French fries?
Using double frying at different temperatures, starting with a lower temp to cook through and then a higher temp to crisp the exterior, is the key to achieving the crispiest French fries.
Should I soak my potatoes before frying to get crispy fries?
Yes, soaking sliced potatoes in cold water for at least 30 minutes helps remove excess starch, resulting in crispier fries after frying.
What type of oil is best for making crispy French fries?
High smoke point oils like vegetable oil, canola oil, or peanut oil are ideal because they can withstand high temperatures and help achieve a crispy texture.
How do I ensure my French fries stay crispy after frying?
Drain fries on paper towels immediately after frying, and avoid overcrowding the pan. For extra crispness, you can also place fried fries in a warm oven for a few minutes before serving.
Can I make crispy French fries in an air fryer?
Yes, using an air fryer can produce crispy French fries with less oil. Toss the potatoes with a small amount of oil, cook at high heat (around 400°F/200°C), and shake the basket halfway through for even crispiness.
