Best Oil Temperature for Frozen French Fries

French fries are a delicious side dish or quick snack paired with a yummy sauce, and making it from scratch is time-consuming, so many opt for the frozen one instead.

Which brought about the question, What is the oil temperature for frozen French fries to get the same crispy yet soft texture as the fresh ones? Also, the secret of delectable fries lies in the frying process. The oil needs to be at the right temperature, and if it is too cool, it will absorb the oil; if it is too hot, it will burn.

So, what is the oil temperature for frozen French fries? Frozen fries should be deep-fried at around 350°F for 5-10 minutes, depending on the thickness of the fries. Slim-cut fries can be prepared within 5-8 minutes, while chunky cuts can take about 8-10 minutes.

Best Oil Temperature for Frozen French Fries

The best oil temperature to deep-fry frozen French fries is 325oF. You can also deep fry French fries for three minutes at 375 degrees or until golden brown and crispy. One of the most critical steps when deep-frying chips, is to ensure that the oil is at the right temperature.

If you add too many frozen potatoes and then cook them in hot oil, you will end up with soggy fries due to the sudden temperature drop. Using the proper deep-frying temperature ensures the fries are cooked through and gives them a crispy exterior.

Also, if you want to use a temperature higher than 375 degrees, you will  need to increase the tendency of burning your French fries or they may end up being undone. Moreover, some types of French fries, such as shoestring and basket-weave fries, can be done at 375 degrees F. 

How Are Frozen French Fries Made?

Before we explain further on how to fry frozen French fries at home, it is crucial to know how they are made since their preparation plays a massive role in their cooking time . Frozen fries are prepared the same way as home-cooked fries, but a few factors give pre-packaged fries an advantage.

firstly is the potatoes themselves. Not all French fries are made the same way! It is common to get varying textures and flavors from different types of potatoes. 

The type, size, and age matter when picking the perfect potatoes for French fries; manufacturers only source the best potatoes from around the region. Frozen French fries go through multiple processes to achieve that distinct crispy and fluffy texture.

This is how:

Blanching the Potatoes

The potatoes are cut and then blanched in hot water for some time which helps to soften the outer skin of the fries and improve the texture.

Blanching also helps the fries achieve a long shelf-life as it kills off any bacteria and help to reduce frying time of the fries too. Once blanched, the potatoes then rest in cold water.

Frying Process

This frying process is essential as it adds flavor with specialized cooking oils and helps the fries achieve a crispy exterior and a fluffy interior.

The fries are quickly fried in an industrial-grade fryer that half-cooks the fries at a specific temperature. This process takes a few minutes but produces a crispy exterior when refried at home. The oil also prevents the fries from sticking to each other while packaged. 

Every manufacturer has their secret sauce when preparing the fries, but most follow the same procedures with minor adjustments!

Packaging Process

After blanched and half-fried, the fries are moved to a flash-freezing machine, frozen to below 0°F temperatures, allowing them to retain their texture, moisture, and flavor

Keep in mind that slowly freezing them will result in low-quality and dry fries, so they must be flash-frozen. The fries are then kept at 0°F and can last for a few months at home. 

Ways to Fry Frozen French Fries

Do You Need to Thaw Frozen French Fries Before Deep-Frying?

Now that you know it’s acceptable to deep fry frozen your French fries, the next question is how long does it take to thaw them before frying.
