Airfryer Fries: How to Get Them Perfectly Crispy

Reading time: approx. 7 minutes

Let's be honest: Airfryer fries are the main reason most people buy an air fryer. But if you're truly honest — were your first attempts really perfect? Probably not. Sometimes too soft, sometimes too dry, sometimes unevenly browned. We're changing that today.

In this guide, I'll show you step-by-step how to make airfryer fries that are crispy on the outside and fluffy on the inside — whether from fresh potatoes or frozen. Plus: the most common mistakes and how to avoid them.

Fresh Potatoes or Frozen Fries?

Both work wonderfully in an air fryer — but the path to the result is different.

Fresh Potatoes

Fresh fries require a bit more preparation, but they taste significantly better. You have full control over the cut, seasoning, and amount of oil. Ideal for anyone who truly wants to get the most out of them.

Floury potatoes like Agria or Bintje are best. They have a higher starch content, which ensures more crispiness. Waxy varieties tend to become chewy rather than crispy.

Frozen Fries

Frozen fries are already pre-fried and seasoned. They require less preparation and almost cook themselves. The downside: you have less influence over the quality of the ingredients. Nevertheless, they are significantly healthier from the air fryer than from a classic deep fryer.

Step-by-Step: Perfect Fries from Fresh Potatoes

Step 1: Cut the Potatoes

Peel the potatoes and cut them into uniform sticks — about 1 cm thick and 7-8 cm long. Uniformity is crucial: fries of different thicknesses will cook at different rates. Thinner sticks will be crispier, while thicker ones will remain softer inside. Find your sweet spot.

Pro-tip: A french fry cutter saves time and ensures consistent results. But a sharp knife works just as well.

Step 2: Soaking — the Underestimated Trick

Place the cut potato sticks in cold water for at least 30 minutes. Even better: 1-2 hours or even overnight in the refrigerator.

Why? The water draws out excess starch from the potatoes. And this starch is the enemy of crispiness — it makes the fries soggy instead of crunchy. You'll notice the effect as the water becomes cloudy. That's the starch coming out.

Step 3: Dry Thoroughly

This step is most often skipped — and is also one of the most important. Moist fries will not get crispy. Period.

Drain the fries and pat them thoroughly dry with a clean kitchen towel or paper towels. Take your time. Every drop of water that remains will turn into steam and prevent browning.

Step 4: The Right Amount of Oil

Most mistakes happen here. Too much oil makes the fries greasy, too little makes them dry out. The perfect amount is thinly and evenly distributed.

This is where an oil spray makes all the difference. Instead of pouring oil over the fries (which will always be uneven), you spray a fine layer over all the sticks. With a precise spray like AÉRfryPRO's, you get only 1.6 ml per spray — enough for an even coating without drowning the fries.

For one serving (approx. 400g of potatoes), 3-4 sprays are sufficient. That's less than 7 ml of oil. For comparison: in a classic deep fryer, the same fries swim in 1-2 liters of oil.

Which oil? Olive oil is excellent for fries — it adds a slightly spicy flavor and is heat-stable up to 230°C. If you want a neutral taste, opt for avocado oil.

Step 5: Seasoning

Season the fries after oiling, but before air frying. The oil helps the spices adhere to the potatoes.

Basic seasoning:

• Salt (preferably after cooking — salt draws out moisture)
• Paprika powder (sweet or smoked)
• A pinch of garlic powder
• Optional: a little cornstarch (1 tbsp per 500g) for extra crunch

Mix everything in a large bowl so that each fry is evenly seasoned.

Step 6: Temperature and Time

Here comes the two-stage method — the absolute game-changer:

1. First phase: 160°C for 15 minutes — The fries cook through and become soft inside.
2. Second phase: 200°C for 8-10 minutes — The outer layer turns golden brown and crispy.

This trick mimics the double frying from professional kitchens — but without the oil bath.

Step 7: Don't Forget to Shake

Shake the basket or turn the fries every 5-7 minutes. This ensures that all sides are evenly exposed to the hot air. Without shaking, you'll have crispy fries on one side and white, soft spots on the other.

Bonus tip: After shaking in the second phase, give the fries another quick spray of oil. This greatly enhances crispiness.

Frozen Fries in the Airfryer: Here's How

Frozen fries are easier, but there are still a few tricks:

• Do not thaw — place them directly frozen into the air fryer
• Do not overload the basket — a maximum of one layer, preferably only half full
• Temperature: 180-200°C for 12-18 minutes (depending on thickness)
• Shake here too — shake vigorously once halfway through the cooking time
• A light oil mist helps here too — a spray after shaking makes them extra crispy

Many frozen fries are already pre-oiled. Nevertheless, they benefit from an additional fine spray — especially if you use oven fries, which can sometimes be a bit dry in the air fryer.

The 5 Most Common Mistakes with Airfryer Fries

1. Overloading the Basket

The classic mistake. If the fries are piled on top of each other, the air won't circulate properly. Result: soggy instead of crispy fries. It's better to do two smaller batches.

2. Not Dried Enough

Moisture is the biggest enemy of crispiness. Soaking is important — but afterwards, the fries must be truly dry.

3. Pouring Oil Instead of Spraying

Pouring oil over the fries drowns the bottom ones and leaves the top ones dry. An even mist distributes the oil where it belongs — on the surface of each individual fry.

4. Using the Wrong Oil

Oils with a low smoke point (like cold-pressed flaxseed oil or unfiltered olive oil) start to smoke and become bitter at airfryer temperatures. Always use heat-stable oils — refined olive oil or avocado oil are ideal.

5. Not Shaking

Without regular turning, airfryer fries will never be evenly crispy. Set a timer — pull out the basket briefly and shake it every 5-7 minutes.

Variations: Fries with a Twist

Once you master the basic technique, you can get creative:

• Sweet Potato Fries: Same method, but at 190°C and for a slightly shorter time. A little cornstarch helps with crispiness.
• Garlic Parmesan Fries: Immediately after cooking, mix with freshly grated Parmesan and garlic oil.
• Cajun Fries: Season with Cajun seasoning mix before cooking for a spicy kick.
• Truffle Fries: After cooking, spray with truffle oil and sprinkle with sea salt.
