Mix chopped garlic,salt and oregano(or any seasoning) with 2 tablespoon oil,keep it aside.
Wash and remove any dirt from the potatoes.
Place the potato alongside 2 inverted spoons. Cut the potato with the knife using the spoons to prevent from cutting all the way down through the potato.(refer to picture in the post above)
Soak these in water again to remove any starch from the slices, else they will stick together.
Dry it on paper towels to remove excess water.
Preheat the air fryer at 200 deg C (390 F). for 10 mins. Brush 1 tbsp. oil on top of the potatoes. Air fry for 8 mins at 200 deg C (390 F) to make hasselback potatoes in the air fryer.
Apply the oil with seasoning on tops of the potatoes Air fry further for 15-16 mins at 200 deg C(390 F) or until the potatoes are cooked with crispy edges. Bigger potatoes will need few more minutes.(5-7 minutes more). Serve hot/warm
While picking these up from the air fryer, be careful as they might break off,I prefer to use a turner or a spatula to pick these up from the base of the potato .
