How Long to Cook French Fries in Air Fryer
Introduction to Cooking French Fries in Air Fryers
A french fry is one of those universally loved snacks that has been enjoyed for generations. Traditionally, fries were deep fried in oil to achieve their characteristic crispy exterior and fluffy interior. However, deep frying often involves a lot of oil and can be messy. Today, air fryers offer a healthier and more convenient alternative to prepare crispy french fries using hot air circulation instead of deep frying.
Air fryer french fries are popular because they use less oil yet can achieve that golden, crunchy texture that many crave. Whether you’re cooking air fryer frozen french fries straight from the freezer or making homemade french fries from fresh russet potatoes, understanding how long to cook french fries in air fryer is essential to getting perfect results. This guide provides detailed cook times, ingredient tips, seasoning ideas, and troubleshooting advice for making crispy air fryer french fries every time.
How Air Fryers Work
Air fryers use a heating element and a powerful fan to circulate hot air rapidly around the fries placed in the air fryer basket. This process cooks the fries evenly by surrounding them with hot air, which removes moisture from the surface and crisps the exterior without soaking the fries in oil.
The air fryer basket allows hot air to reach all sides of the fries when arranged properly, typically in a single layer. If the basket is overcrowded, the fries can cook unevenly and lose their crispiness.
Why Use Air Fryers for French Fries
Air fryers have quickly become a favorite appliance for making fries because they:
-
Require less oil compared to traditional deep frying, making fries less greasy and lower in calories.
-
Cook fries faster than an oven while providing similar or better crispiness.
-
Allow you to cook various types of fries, including frozen fries, homemade french fries, sweet potato fries, and more.
-
Are easier and cleaner to use compared to deep frying.

Steak Fries
Thicker, chunkier fries that need longer cooking times for a crispy outside and soft inside.
Ingredients for Air Fryer French Fries

-
Russet potatoes or frozen fries
-
Olive oil (1–2 teaspoons per batch) to help crisp the fries
-
Seasonings such as salt, pepper, garlic powder, paprika, or herbs
How to Make French Fries in an Air Fryer

Step 1: Preheat the Air Fryer
Preheat the air fryer for 3–5 minutes to help fries cook evenly and become crispy.
Step 2: Prepare the Fries
For homemade fries, cut the potatoes evenly and soak them in cold water for at least 30 minutes to remove excess starch. Dry thoroughly.
Step 3: Season the Fries
Toss fries in a small amount of olive oil and your preferred seasonings. Frozen fries usually do not require additional seasoning.
Step 4: Arrange in the Basket
Place fries in the air fryer basket in a single layer, avoiding overcrowding for even cooking.
Step 5: Cook the Fries
-
Frozen fries: cook at 400°F for 10–15 minutes, shaking the basket halfway through.
-
Homemade fries: cook at 380°F for 15–20 minutes, shaking halfway.
-
Sweet potato fries: cook at 380°F for 18–22 minutes, shaking halfway.
-
Steak fries: cook at 380°F for 20–25 minutes.
Step 6: Crisping
If fries are not yet crispy and golden, cook for an additional 2–3 minutes, checking frequently to avoid burning.
Cooking Science – Why Fries Get Crispy in the Air Fryer
Fries become crispy when moisture evaporates from their surface during cooking. The circulating hot air removes water and, with the help of a thin coating of oil, browns the fries to create a crunchy crust. Russet potatoes, with their higher starch content, are ideal for achieving crispy air fryer french fries.
Air Fryer Fries Tips for Perfect Results
Preheat Before Cooking
Always preheat your air fryer for optimal results.
Shake the Basket Halfway
Shaking or tossing fries halfway through the cook time exposes all sides to hot air and promotes even crisping.
Cook in Batches
Avoid overcrowding to prevent soggy fries and ensure every fry gets crispy.
Use Minimal Oil
Use just enough olive oil to lightly coat the fries. Too much oil can make fries greasy rather than crispy.

Troubleshooting Common Problems
Soggy Fries
Caused by overcrowding or moisture. Solution: Cook in smaller batches and dry homemade fries thoroughly before cooking.
Burnt Fries
Cause: Too high temperature or cooking too long. Solution: Reduce temperature by 10–20°F and check fries frequently.
Uneven Cooking
Cause: Uneven cutting or stacking fries in the basket. Solution: Cut fries uniformly and cook in a single layer.
Storing and Reheating Leftover Fries
Store leftover fries in an airtight container in the refrigerator for up to 2 days. To reheat, place fries back in the air fryer for 3–4 minutes until crispy again. Avoid reheating in the microwave to prevent sogginess.
