In the meantime, place the flour, salt, and black pepper in a shallow bowl and stir together. In another bowl, beat the eggs. Place the panko breadcrumbs in another bowl.

Place a chicken cutlet in the flour bowl and flip it until it is evenly covered. Then dip it in the egg bowl until covered. Finally, place it in the breadcrumb bowl and flip until the chicken cutlet is covered completely. Repeat with all chicken cutlets. Set aside.

Option 1: Preheat some vegetable oil in large pan over medium heat. Then add the breaded chicken cutlets and sear from both sides until browned and cooked through. Option 2: Preheat your air fryer to 400 °F (200 °C). Place the chicken cutlets in the air fryer basket. Generously spray them with oil. Then flip and spray the other side. Air fry for 10-15 minutes until crispy.
¼ cup vegetable oil or oil spray
Next, add the Japanese curry roux to the pot and continue to simmer for 5 minutes while stirring the curry. This ensures that the roux dissolves and the curry thickens.
