How Long To Deep Fry Frozen French Fries?

Frozen French fries have become a staple in many households due to their convenience and delicious taste. Whether hosting a casual gathering or craving a quick snack, these frozen delights offer a simple solution. However, achieving that perfect crispy texture and golden-brown color can be challenging.

In this article, we will explore the process of making frozen French fries, provide instructions on how long to deep fry frozen french fries, offer some tips and tricks for optimal results, and even delve into how to make your homemade frozen fries.

How Are Frozen French Fries Made?

Not all French fries are created equal, and the type of potato used can significantly impact the texture and flavor of the final product. Some popular varieties include Russet, Yukon Gold, and Red Bliss, each lending unique qualities to the fries. Once the potatoes are selected, the preparation process begins.

The first step in creating frozen French fries is blanching. Blanching involves briefly immersing the potatoes in boiling water, which serves two purposes: it softens the fries and extends their shelf life. Some brands may incorporate additional blanching steps to enhance the texture of their fries, resulting in a crispier end product.

After blanching, the partially cooked fries undergo frying. This step typically involves half-cooking the fries in an industrial-grade fryer. Specialized cooking oils impart flavor and contribute to the desired texture. Additionally, measures are taken to prevent the fries from sticking together during packaging.

Once fried, the French fries are swiftly packaged to maintain their quality. Flash-freezing the fries below 0°F is crucial to retain their texture, moisture, and flavor. Quick freezing ensures the fries remain as close to their freshly cooked state as possible.

How to Cook Frozen Fries at Home

Once your frozen fries have arrived, it is time to cook them to perfection in your kitchen.

Here’s what you’ll need:

  1. A large, heavy-bottom pot for deep frying ensures enough room for the fries to cook evenly.
  2.  For deep frying, 1-2 liters of cooking oil, such as vegetable or canola oil.
  3.  2.2 lbs. of frozen fries, or adjust the quantity per your preference.
  4.  A cooking thermometer to monitor and maintain the oil temperature.

To cook the frozen fries:

  1. Heat the oil in the pot to 350°F, using the cooking thermometer to ensure accurate temperature control.
  2.  Carefully add the frozen fries to the pot, being mindful not to overcrowd them. Overcrowding can result in uneven cooking.
  3.  The cooking time and technique may vary based on the thickness of the fries. Slim-cut fries typically require 5-8 minutes, while chunky cuts may require 8-10 minutes. Adjust the cooking time accordingly.
  4.  Keep an eye on the fries and check for a golden-brown color and a crispy texture. This visual cue indicates that the fries are done.
  5.  Once done, remove them from the heat and drain them on a paper towel or sieve to absorb any remaining oil.
  6.  Season the fries with salt or your preferred seasonings and serve them hot.

Expert Tips & Techniques for Perfectly Cooking Frozen Fries

Cooking frozen fries can be an art, and here are some tips and tricks to help you achieve the best results:

  • Use visual cues to determine if the oil is at the right temperature. When a fry floats to the top immediately after being added to the oil, it indicates it is hot enough for frying.
  •  Pay attention to the bubbles during cooking. If fewer bubbles form around the fries, the moisture content is reduced, resulting in a crispier result.
  •  If needed, extend the cooking time slightly to ensure the fries reach the desired level of crispiness. Keep an eye out for the golden-brown color as an additional indicator of doneness.
  •  Season the fries while hot to ensure the flavors are evenly distributed. This step allows the seasoning to adhere to the fries, enhancing the overall taste.
  •  Properly draining the excess oil is crucial to avoid sogginess. Using a sieve or a slotted spoon allows the oil to drain away, leaving behind deliciously crispy fries.
  •  To prevent sogginess, you can also transfer the cooked fries onto a paper towel-lined plate. Move the fries around to prevent them from sitting in any accumulated oil.

Homemade Frozen Fries: A Step-by-Step Guide

If you prefer a more hands-on approach, making homemade frozen fries is a fantastic alternative to pre-packaged options. Here’s how you can do it:

  1. Start by cleaning, peeling, and cutting your desired type of potato. Russet potatoes are commonly used for their starchy content, resulting in crispy fries.
  2.  Blanch the potato slices in boiling water for 3-5 minutes. This brief blanching process helps retain the texture and prevents discoloration.
  3.  After blanching, transfer the potatoes to an ice bath for around 10 minutes to cool them down and halt the cooking process.
  4.  Once cooled, pat the blanched potato slices dry with a paper towel to remove excess moisture.
  5.  Arrange the potato slices on a tray in a single layer and place them in the freezer. This initial freezing on the tray helps prevent the fries from sticking together.
  6.  Once the potato slices are frozen, transfer them to a freezer-safe plastic bag for long-term storage.

Following these steps, you can have your homemade frozen fries ready whenever you’re in the mood for a tasty snack or side dish.


Can You Bake Frozen Fries?

Yes! Baking frozen fries can be a healthier alternative. Preheat the oven to 450°F and arrange frozen fries on an aluminum or porcelain baking sheet in an even layer. Bake for 12-15 minutes, flipping them halfway through to achieve a crispy texture.

Should You Defrost Fries Before Cooking?

If you’re short on time, you can skip defrosting and immediately fry the frozen fries. Just remember that the cooking time may be slightly longer, so pay close attention to the visual cues of doneness.

Air-Frying Frozen Fries: Is It Possible?

Yes, air-frying has gained popularity for its ability to achieve a crispy result with less oil. Set your air fryer to 400°F and cook the frozen fries for 15-20 minutes, shaking the basket occasionally to ensure even cooking.


In conclusion, cooking frozen French fries can be a simple and rewarding process. By understanding the preparation methods behind frozen fries, following the cooking instructions, and applying some helpful tips and tricks, you can enjoy delicious, crispy fries in your home.

And if you’re feeling adventurous, why not make homemade frozen fries for a personalized touch? So grab a bag of frozen fries, fire up that deep fryer, and savor the irresistible taste of perfectly cooked French fries!
