Peel and chop the potatoes into ¼ inch sticks.
In a bowl add 4-5 cups water and 1 ½ teaspoon salt. Mix and add the potatoes. Soak for 30 minutes.
Mix together all the spices. Leave out the oil.
After 30 minutes, drain the potatoes and spread them out on a clean muslin cloth or napkin.
Let the fries dry for 10-12 minutes or pat them dry and use immediately.
Transfer the fries to a tray and add the oil. Mix well and add the spices. Mix well to evenly coat the fries.
Preheat the air fryer to 380 F. Set time to 15 minutes. Once the display reads 'Add Food' spread ½ the fries in a single layer.
Let the fries cook till the display reads 'Turn Food'. Shake them and let them cook till the fryer beeps.
Repeat the steps for the remaining fries but reduce time to 12 minutes. If the fries are not crisp, air fry for additional 2-3 minutes.
Open the Air Fryer and transfer the fries to a plate. Sprinkle some chaat masala, green onions and cilantro.
Serve hot with ketchup and green cilantro chutney.
