Using a sharp knife, cut paneer into rectangular or square pieces about ½ inch thick. Keep in mind to cut them at least the size of your burger buns so that each bite has paneer. I usually cut them rectangular and bit larger than the size of burger buns.
In a mixing bowl, sift together besan and rice flour.Add all the spices, garlic powder, onion powder and salt to the flour mixture.
Slowly pour in water while whisking to create a thick yet smooth batter. It should flow easily off the whisk but still coat the back of a spoon. If it’s too thick, the final result may turn out dry; too thin, and the batter won’t adhere properly to the paneer.
In a wide & shallow dish, mix together breadcrubs, grated parmesan cheese, salt and black pepper powder. Let stand.
Dip each paneer rectangle into the prepared besan batter, turning to coat all sides evenly. Gently lift and let excess batter drip for a few seconds.
Place the besan batter-coated paneer into the dish filled with breadcrumbs, pressing lightly to ensure a uniform, crisp coating.
Lightly brush the air fryer rack with oil to help prevent sticking. Arrange the breaded paneer pieces in a single layer, leaving space between them. I use a 5.8qt glass air fryer and its fits 2-3 paneer pieces at a time.Depending on your air fryer, you may need to work in batches.
Spray the tops of the paneer with oil and air fry at 360°F for 8 to 10 minutes, flipping halfway through, until the coating turns golden and crisp. Adjust the timing based on how hot your air fryer runs.
