French fries are a staple in many cuisines around the world, and their popularity can be attributed to their crispy exterior and fluffy interior. However, achieving this perfect texture can be a challenge, especially for those who are new to cooking. One technique that has gained popularity in recent years is double cooking French fries. In this article, we will explore the benefits of double cooking French fries, the science behind it, and provide a step-by-step guide on how to do it.
What is Double Cooking French Fries?
Double cooking French fries is a technique where the potatoes are cooked twice, once at a low temperature to cook the interior, and again at a high temperature to crisp the exterior. This technique is also known as “par-cooking” or “pre-cooking.” The idea behind double cooking is to cook the potatoes until they are partially cooked, then let them cool down before finishing them off in hot oil. This technique allows for a crispy exterior and a fluffy interior, making it a game-changer for French fry enthusiasts.
The Science Behind Double Cooking French Fries
When potatoes are cooked, the starches inside the potato break down into sugars, which then caramelize and create a crispy exterior. However, if the potatoes are cooked too quickly, the starches do not have time to break down, resulting in a soggy exterior. By cooking the potatoes twice, we allow the starches to break down slowly, resulting in a crispy exterior.
Another benefit of double cooking is that it allows for better control over the cooking process. When potatoes are cooked once, it can be difficult to achieve the perfect texture, as the cooking time can vary depending on the size and type of potato. By cooking the potatoes twice, we can control the cooking time and temperature, ensuring that the potatoes are cooked to perfection.
Benefits of Double Cooking French Fries
There are several benefits to double cooking French fries, including:
- Crispy Exterior: Double cooking allows for a crispy exterior, which is achieved by cooking the potatoes at a high temperature.
- Fluffy Interior: By cooking the potatoes at a low temperature first, we can achieve a fluffy interior.
- Better Control: Double cooking allows for better control over the cooking process, ensuring that the potatoes are cooked to perfection.
- Reduced Oil Absorption: Double cooking reduces the amount of oil absorbed by the potatoes, resulting in a healthier French fry.
Choosing the Right Potatoes
When it comes to double cooking French fries, the type of potato used is crucial. Look for potatoes that are high in starch, such as Russet or Idaho potatoes. These potatoes will yield a crispy exterior and a fluffy interior.
A Step-by-Step Guide to Double Cooking French Fries
Double cooking French fries is a simple process that requires some planning and patience. Here is a step-by-step guide to double cooking French fries:
Step 1: Peel and Cut the Potatoes
Peel the potatoes and cut them into long, thin strips. The size of the strips will depend on the type of French fry you are trying to achieve. For example, if you want to make thin, crispy French fries, cut the potatoes into thin strips. If you want to make thicker, chunkier French fries, cut the potatoes into thicker strips.
Step 2: Soak the Potatoes
Soak the potatoes in cold water for at least 30 minutes. This will help to remove excess starch from the potatoes, resulting in a crispy exterior.
Step 3: Cook the Potatoes at a Low Temperature
Cook the potatoes in a large pot of boiling water at a low temperature (around 180°F) for 5-7 minutes, or until they are partially cooked. The potatoes should still be slightly firm in the center.
Step 4: Let the Potatoes Cool Down
Let the potatoes cool down to room temperature. This is an important step, as it allows the potatoes to dry out slightly, resulting in a crispy exterior.
Step 5: Heat the Oil
Heat a large pot of oil (such as peanut or vegetable oil) to a high temperature (around 375°F).
Step 6: Finish Cooking the Potatoes
Carefully add the potatoes to the hot oil and cook for 2-3 minutes, or until they are golden brown and crispy.
Step 7: Drain and Serve
Drain the French fries on paper towels and serve hot.
Tips and Variations
Here are some tips and variations to help you achieve the perfect double-cooked French fries:
- Use the Right Oil: Use a high-quality oil with a high smoke point, such as peanut or avocado oil.
- Don’t Overcook: Don’t overcook the potatoes, as this can result in a soggy exterior.
- Experiment with Seasonings: Experiment with different seasonings, such as garlic powder or paprika, to add flavor to your French fries.
- Try Different Types of Potatoes: Try using different types of potatoes, such as sweet potatoes or Yukon gold potatoes, to achieve a different flavor and texture.
Common Mistakes to Avoid
Here are some common mistakes to avoid when double cooking French fries:
- Not Soaking the Potatoes: Not soaking the potatoes can result in a soggy exterior.
- Overcooking the Potatoes: Overcooking the potatoes can result in a soggy exterior.
- Not Letting the Potatoes Cool Down: Not letting the potatoes cool down can result in a soggy exterior.

What is double cooking and how does it affect French fries?
Double cooking is a cooking technique that involves cooking French fries twice, with a resting period in between. This technique helps to achieve crispy perfection by removing excess moisture from the potatoes. When potatoes are cut into French fry shapes, they release starches, which can make them sticky and soft. Double cooking helps to break down these starches, resulting in a crunchier exterior.
The first cook helps to cook the potatoes through, while the second cook crisps up the exterior. By cooking the French fries twice, you can achieve a perfect balance of crunch and fluff. This technique is especially useful for achieving restaurant-quality French fries at home. With double cooking, you can say goodbye to soggy, limp French fries and hello to crispy, golden perfection.
What type of potatoes are best for double cooking?
The type of potatoes you use can greatly affect the outcome of your double-cooked French fries. Look for potatoes that are high in starch, such as Russet or Idaho potatoes. These potatoes will yield a crisper exterior and a fluffier interior. Avoid using waxy potatoes, such as Yukon Gold or red potatoes, as they will not produce the same level of crispiness.
Russet potatoes are the most commonly used potatoes for French fries, and for good reason. They have a high starch content, which makes them ideal for double cooking. Idaho potatoes are also a good choice, as they have a slightly sweet flavor and a light, fluffy texture. Whichever type of potatoes you choose, make sure to select ones that are high in starch for the best results.
How do I prepare the potatoes for double cooking?
To prepare the potatoes for double cooking, start by peeling and cutting them into your desired French fry shape. Cut the potatoes into long, thin strips, making sure to cut them as evenly as possible. This will help them cook evenly and prevent some fries from becoming overcooked.
Next, soak the cut potatoes in cold water for at least 30 minutes to remove excess starch. After soaking, drain the potatoes and pat them dry with paper towels to remove excess moisture. This step is crucial in helping the potatoes become crispy. If you don’t remove excess moisture, the potatoes will steam instead of crisp up during the cooking process.
What is the best way to cook the French fries for the first cook?
The first cook is an important step in achieving crispy perfection. To cook the French fries for the first time, heat a pot of oil to around 325°F (165°C). Carefully add the potatoes to the hot oil in batches, being careful not to overcrowd the pot. Cook the potatoes for around 3-5 minutes, or until they are slightly tender but still pale in color.
It’s essential to cook the potatoes at a lower temperature for the first cook to prevent them from becoming too dark or crispy. You want to cook them just enough to cook them through, but not so much that they become overcooked. If you cook them too long, they will become greasy and soggy. By cooking them at a lower temperature, you can achieve a tender interior without sacrificing crispiness.
How long should I let the French fries rest between cooks?
After the first cook, it’s essential to let the French fries rest for at least 30 minutes to an hour. This allows excess moisture to escape, which helps the potatoes become crispy during the second cook. You can let them rest at room temperature or in the refrigerator, whichever is more convenient.
During this time, the potatoes will undergo a process called retrogradation, where the starches break down and re-form into a more crystalline structure. This process helps the potatoes become crisper and more flavorful. By letting the potatoes rest, you can achieve a crunchier exterior and a fluffier interior.
What is the best way to cook the French fries for the second cook?
For the second cook, heat the oil to a higher temperature, around 375°F (190°C). Carefully add the rested French fries to the hot oil in batches, being careful not to overcrowd the pot. Cook the potatoes for around 2-3 minutes, or until they are golden brown and crispy.
It’s essential to cook the potatoes at a higher temperature for the second cook to achieve crispiness. You want to cook them just enough to crisp up the exterior, but not so much that they become overcooked. If you cook them too long, they will become greasy and soggy. By cooking them at a higher temperature, you can achieve a crunchy exterior and a fluffy interior.
Can I double cook French fries in the oven instead of deep-frying?
Yes, you can double cook French fries in the oven instead of deep-frying. To do this, preheat your oven to 400°F (200°C). Cook the potatoes for the first time in the oven for around 15-20 minutes, or until they are slightly tender but still pale in color. Then, let them rest for at least 30 minutes to an hour before cooking them again in the oven at a higher temperature, around 425°F (220°C), for an additional 10-15 minutes, or until crispy.
Keep in mind that oven-cooked French fries will not be as crispy as deep-fried ones. However, they can still be delicious and a healthier alternative. To achieve crispiness in the oven, make sure to cook the potatoes at a high temperature and use a small amount of oil to help them brown. You can also try using a broiler to give the French fries an extra crispy boost.
