Make the Caesar Dressing: Combine all the dressing ingredients in a small bowl or blender. Mix or blend until well combined and smooth. Add salt and pepper to taste, then mix or blend again. If needed, add some water to thin it out. Taste test to adjust seasoning if needed.
Prep the Chicken: Place the chicken on a cutting board, cover with plastic wrap, and pound evenly with a rolling pin or meat tenderizer. Season both sides with salt and pepper.
Place the flour in a large shallow bowl.
Beat the eggs in a second large shallow bowl.
In a third large shallow bowl, stir together the panko, Italian breadcrumbs, and Parmesan.
Dredge each chicken fillet in flour, then egg, then the breadcrumb mixture (press the breadcrumbs on with your fingers) and place in your air fryer basket. Spray with cooking oil spray.
Cook the Chicken: Air fry at 390°F (200°C) for 12-13 minutes. After 7 minutes, open the air fryer and carefully flip the chicken, and spray with cooking oil spray again. Continue cooking for an additional 5-6 minutes, depending on the size of the chicken breast. You might need to cook it in batches of two.
Prepare the Salad: Toss the romaine and shaved Parmesan with half of the Caesar dressing, adding more as needed.
Serve the salad on top of the chicken with some freshly grated Parmesan and a squeeze of lemon.
Enjoy!
