Thoroughly rinse and wash the potatoes. You can either peel them or keep the skin on.

Place a potato lengthwise on a cutting board and use a crinkle cutter to create a cross-hatch waffle pattern by making cuts at a 90-degree rotation. Repeat for all potatoes.

Soak the cut potatoes in cold water for about 25 minutes. Boil a large pot of water while they soak.

Add the soaked potatoes to the boiling water and cook for 3-5 minutes until partially cooked yet firm. Ensure they fit comfortably in your air fryer basket in a single layer.

Drain the potatoes on paper towels and pat them gently to dry.

Transfer the fries to a large bowl, add olive oil, and delicately coat the potatoes.

Arrange the fries in a single layer in the air fryer basket.

Set the Air Fryer to Air Fry mode at 400°F and cook for 15 minutes.

For multiple batches, repeat steps 4-7 as needed.

Once all batches are crispy, refresh the fries at 375°F-390°F for 3-5 minutes in a single basket.

Season with salt to taste, toss well, and indulge in your crispy waffle fries!
