Using a sharp knife, cut the potatoes into 4-5 thick slices and then each slice into uniform strips, about ¼ inch thick.

Take a large bowl and fill it with ice-cold water. Transfer the cut potatoes to the bowl and soak for 10 - 30 minutes.

While the potatoes soak, Preheat your air fryer to 380°F degrees for 5 minutes.

Once the potatoes have finished soaking, drain the water completely and transfer the potatoes to a clean kitchen towel. Pat the potatoes dry with the kitchen towel or paper towel.

Add the potatoes to a large bowl, drizzle with oil, and sprinkle red chili powder, turmeric powder, garam masala, garlic powder, black pepper, and salt followed by cornstarch. Toss to coat evenly.

Spray the air fryer basket with a light layer of oil. Arrange the seasoned potato fries in the preheated air fryer basket in a single even layer. Avoid overcrowding; cook in batches if necessary.

Repeat with the remaining fries until they have all been cooked. Then add all fries together in the air fryer and air fry for another 2 mins to crisp them up.

Garnish with chopped cilantro, sprinkle chaat masala and dizzle lemon juice and serve immediately.
