French fries are arguably the most universally loved side dish and snack. That perfect fry delivers a golden-brown crisp exterior, a fluffy interior, and a satisfying crunch with every bite. While traditional deep-frying achieves this beautifully, it's messy and uses a lot of oil. Oven-baked fries often fall short, turning out limp and uninspiring.

But what if you could get that deep-fried crunch with the convenience and healthier aspects of your air fryer? The good news is, you can! This Step-by-Step Guide to Perfect Air Fryer French Fries will unlock the secret to achieving an incredible double crunch, making your homemade fries rival (and often surpass) your favorite fast-food joint.
Why "Double Crunch" Makes All the Difference
The "double crunch" technique involves a crucial extra step that transforms good air fryer fries into extraordinary ones. It's all about breaking down the starches on the exterior of the potato and then building up an ultra-crispy crust, giving you a truly addictive texture that stays crispy longer.
Ingredients You’ll Need
2 Large Russet Potatoes: (about 1.5 - 2 lbs, ideal for fries)
2 tbsp Neutral Oil: (canola, vegetable, or avocado oil)
1 tsp Salt: (fine sea salt or table salt works best)
Optional: 1/2 tsp garlic powder, 1/4 tsp black pepper, or other seasonings
Equipment
Large Bowl
Colander
Clean Kitchen Towel or Paper Towels
Air Fryer
Step-by-Step Instructions: Mastering the Double Crunch
1. Prep and Cut the Potatoes
Wash the potatoes thoroughly. You can peel them or leave the skin on for a rustic touch (we recommend leaving it on for extra texture and nutrients!).
Cut the potatoes into uniform sticks, about 1/4 to 1/2 inch thick. Consistency is key for even cooking.
2. The First Secret: The Water Soak (Starch Removal)
Place the cut potato sticks in a large bowl and cover them completely with cold water. Let them soak for at least 30 minutes, or even up to a few hours (you can refrigerate them if soaking longer). This step draws out excess starch, which is crucial for achieving crispiness.
3. The Second Secret: The Boil (Par-Cooking for Fluffiness)
Drain the potatoes and rinse them well. Transfer them to a medium pot and cover with fresh cold water. Add a pinch of salt.
Bring the water to a boil, then reduce heat and simmer for 5-7 minutes. The fries should be slightly tender but still firm—do not overcook them to mush!
Drain the potatoes very well in a colander.
4. The Super Dry: Crucial for Crunch
This is a critical step! Lay the par-boiled fries out in a single layer on a clean kitchen towel or several layers of paper towels. Gently pat them completely dry. Let them air-dry for another 5-10 minutes at room temperature. Any remaining moisture will prevent crispiness.
5. Season and Oil
Transfer the dried, par-boiled fries to a large bowl. Drizzle with 2 tablespoons of oil and toss until every fry is lightly coated. Add the salt and any optional seasonings (garlic powder, pepper) and toss again to distribute evenly.
6. The Air Fryer Double Cook
Preheat your air fryer to 380°F (195°C).
Place the seasoned fries in the air fryer basket in a single layer.
Do not overcrowd the basket! Cook in batches if necessary. Overcrowding leads to steaming, not crisping.
First Air Fry (Initial Crisp): Air fry for 15 minutes, shaking the basket vigorously every 5 minutes. The fries should be lightly golden and starting to firm up.
Second Air Fry (Double Crunch!): Increase the temperature to 400°F (205°C). Air fry for an additional 5-10 minutes, shaking frequently, until the fries are deep golden brown and exceptionally crispy.
7. Serve Immediately
Transfer the hot, crispy fries to a serving bowl. If desired, sprinkle with a little extra salt. Serve immediately with your favorite dipping sauces (ketchup, aioli, fry sauce!).
Pro Tips for Fry Perfection
Uniformity is Key: Cut your fries to similar sizes so they cook evenly.
Don't Skimp on Drying: This step, combined with the soak and boil, is the biggest secret.
Batch Cook: Patience pays off. Resist the urge to cram too many fries into the basket.
Season Hot: Always season fries immediately after cooking for the best adherence and flavor.
With this "double crunch" method, your air fryer French fries will go from good to absolutely glorious. Prepare for rave reviews and requests for seconds!
