No need to rack your brains on how to achieve that perfect crispiness, here's how to make French fries that stay crispy for a long time.
Recipe for Long-lasting Crispy French Fries
Ingredients for making long-lasting crispy French fries:
- Potatoes;
- Cooking oil;
- Sea salt;
- Butter.
How to Make Long-lasting Crispy French Fries
Step 1: First, wash the potatoes thoroughly and peel them. Then, cut the potatoes into long, evenly sized strips, neither too thick nor too thin. Cutting them this way will help ensure the fries are crispy without being raw inside.

Steps to Make Crispy French Fries
Step 2: Soak the cut potato strips in salted water for about 15 minutes. At this step, add a little vinegar to the water. Remember, just a little as too much will alter the flavor of the potatoes. Then, quickly blanch them in boiling water, remove promptly, and let them cool and drain.

Coat the potatoes
Step 3: For this method of making French fries, place the drained potatoes in a plastic container and store them in the freezer for about 30 minutes. This is the crucial step to achieve the crispy texture you desire.

Implementing the French fries recipe
Step 4: After 30 minutes, remove the potatoes from the refrigerator. Heat the oil and butter until hot, then add the potatoes to fry. After 4 - 5 minutes, the potatoes will have a beautiful golden color with a crispy outer layer. At this point, you can remove the potatoes, drain the excess oil, and serve.
In addition, you can apply the following methods to make French fries stay crispy for a long time:
- When adding the potatoes to the frying pan, start with low heat, then increase to high heat when you're ready to remove them. This will ensure the fries stay crispy for a long time.
- You can fry the potatoes twice if you have time. For the first fry, make sure the outer skin of the potatoes is slightly dry. Let the potatoes cool, then fry them again until they are completely golden. Remove them and place in a clean, preheated pan. This will make the fries stay crispy for a long time. Alternatively, after the first fry, let the potatoes cool and store them in the refrigerator overnight. The next day, before serving, fry them again for extra crispiness and flavor.
- Bạn có thể pha bột với nước tạo thành hỗn hợp loãng dùng để làm “áo” cho khoai tây. Sau khi ngâm khoai cùng với nước muối, bạn vớt ra rồi nhúng qua nước bột gạo trên, rồi chiên lên. Nếu không dùng nước bột gạo, các bạn có thể lắc khoai với bột gạo sau khi đã để khoai ráo nước.
