Start by setting up a clean workspace. Pat your chicken breast dry with paper towels—this is critical because moisture prevents browning and proper coating adhesion. Place the dried chicken on a cutting board. Now comes the butterflying technique my mother taught me: place your hand flat on top of the chicken breast and use a sharp knife to slice horizontally through the middle, being careful to leave about half an inch uncut on one side so it opens like a book. This creates two thinner, more uniform pieces that cook evenly. Pat the inside surfaces dry as well. The drier your chicken, the better your coating will adhere and the crispier your finished dish will be. This single step prevents the rubbery, peeling-off coating that disappoints so many home cooks.

Prepare three shallow dishes or plates in a row. In the first, whisk your eggs together with a fork until completely combined. In the second, mix your panko breadcrumbs, ¼ cup Parmesan, Italian seasoning, salt, paprika, and black pepper. Stir this mixture well so the seasonings and cheese distribute evenly. The third dish stays empty—this is where you'll place your finished, coated pieces before air frying. Organization matters here. The dredging process goes faster and cleaner when you're not hunting for bowls mid-stream. I learned this in my clinical nutrition training where we emphasized efficiency without sacrificing quality—the same principle applies to home cooking.

Take your first chicken piece and place it in the egg mixture. Turn it to coat both sides completely, allowing excess egg to drip back into the bowl. The egg is your adhesive—it's what makes the breadcrumb coating stick through the cooking process. Don't rush this step. Now place the egg-coated chicken into the breadcrumb mixture. Press firmly with your fingers, working the breadcrumbs into the egg coating. Flip and repeat on the other side. This pressing action is what creates that satisfying crunch in every bite. Gently shake off excess crumbs and place on your empty dish. Repeat with the second piece.

Set your air fryer to 400 degrees Fahrenheit and let it preheat for about 3 minutes. While it's heating, spray your air fryer basket lightly with olive oil spray. This prevents sticking and helps the chicken brown evenly. Don't oversaturate—you want a light coating, not a puddle. Why 400 degrees? This temperature is hot enough to crisp the coating and cook the chicken through without burning the outside before the inside reaches food safety temperature. It's the sweet spot I've learned through countless batches and refined through my dietitian's understanding of how proteins respond to heat.

Place your breaded chicken pieces in the preheated basket in a single layer. Spray the top surface of each piece lightly with olive oil spray. This helps them brown and crisp beautifully. Cook for 5 minutes at 400 degrees without moving them. Resist the urge to peek—the air circulation does its work best when the basket stays closed.

After 5 minutes, carefully flip your chicken pieces using tongs. Spray the newly exposed surface with a light coating of oil spray. Cook for another 5 minutes. At this point, your chicken should be golden brown on both sides and the internal temperature should be approaching 165 degrees Fahrenheit (the safe temperature for poultry according to USDA guidelines). The coating should sound crispy when you touch it, and it should have that beautiful golden color that tells you the Maillard reaction—the chemical transformation that creates flavor and texture—has happened properly.

Now comes the final assembly. Divide your tomato sauce between the two chicken pieces, spreading it evenly over the top surface of each. Top each piece with ¼ cup of shredded mozzarella cheese, then finish with half of the remaining 1 tablespoon of Parmesan. The Parmesan on top creates pockets of extra umami flavor. The reason we add sauce and cheese at the end rather than the beginning is that they need just enough time to meld together and melt without drying out your perfectly cooked chicken. Timing is everything here.

Return your assembled chicken to the air fryer at 400 degrees for 2 minutes. This gives the cheese time to melt completely and the sauce to warm through without overcooking the chicken. After 2 minutes, carefully remove your chicken and check the internal temperature with a meat thermometer—it must reach a minimum of 165 degrees Fahrenheit. If it hasn't reached temperature, return it to the air fryer for another minute and check again. This is non-negotiable for food safety. Once you hit 165 degrees, you're done. If you have a meat thermometer, use it every single time—it removes guesswork and guarantees perfectly cooked chicken. Let your finished chicken parm rest for 2 minutes before serving. This allows the juices to redistribute, keeping your chicken moist and tender.
