Toss the cubed potatoes with 1 tablespoon olive oil, salt, and pepper. Air fry at 400°F for 15–18 minutes, shaking halfway, until golden and crispy.: The aroma of hot oil hitting the surface of the potatoes produces an immediate sizzle and a toasty smell, signaling that the exterior is crisping. You should hear a steady, light crackle as moisture escapes and edges brown, and visually the cubes will shift from pale to golden brown with slightly blistered skin. This texture contrast is what gives the dish excitement, because creamy interiors are preserved while exteriors become crunchy. The why is simple, crisp exteriors mean each bite has both mouthfeel and structure, so the potatoes stand up to the saucy chicken later. A common mistake is overcrowding the air fryer basket, which traps steam and prevents browning; if pieces are crowded, cook in batches for even crisping. Keep an eye on the color around 12 minutes to avoid over darkening.
Heat the remaining olive oil in a large oven-safe skillet over medium-high heat. Season the chicken with paprika, garlic powder, onion powder, salt, and pepper. Sear 6–8 minutes until cooked through.: When the oil shimmers in the skillet, you will smell a faint nuttiness, and the surface will glisten, which means it is hot enough for a good sear. As you add the seasoned chicken , listen for a confident sizzle, that sound indicates the Maillard reaction is happening and savory notes are developing. Visually, the edges of the chicken will take on golden brown patches and firm up, while the centers remain slightly opaque until fully cooked. This sear locks flavor and juices inside, which is crucial for tender results once sauce is added. Avoid moving the pieces constantly; give them a few minutes to form a crust, otherwise they will tear and you lose that caramelized flavor.
Reduce the heat to medium-low. Stir in the BBQ sauce, Worcestershire, and brown sugar (if using). Simmer for 2–3 minutes until the chicken is coated and saucy.: The moment the sauce hits the warm skillet you will notice a sweet and tangy steam rise, and the BBQ sauce will begin to reduce slightly, concentrating flavors. Stirring gently helps the sauce cling to the seared surfaces, creating glossy, caramelized pockets where sugar meets heat. This step is important because it marries seasoning to protein and builds a sticky coating that elevates texture. A common pitfall is simmering on too high a flame, which can scorch the sugars in the sauce and leave a bitter taste, so keep the heat modest and watch the sauce closely.
Add the crispy potatoes into the skillet, tossing everything together so the sauce coats both chicken and potatoes.: When you fold the warm, golden potatoes back into the skillet, the sauce will hiss gently as it rehydrates the crusted surfaces, and you will see shiny ribbons of sauce cling to both the potatoes and chicken . This is the point where textures meet; the crispness may soften slightly but should retain enough bite to contrast with the tender chicken . The purpose of tossing is to ensure even distribution of sauce so each bite has balance. Be careful not to overmix, because extra handling can break apart the potatoes and make the mixture mushy.
Sprinkle mozzarella evenly on top. Place the skillet under the broiler for 2–3 minutes, until the cheese is melted, bubbly, and golden in spots.: As the skillet moves under the broiler you will notice the heat transform the shredded mozzarella cheese into a bubbling, stretchy layer that browns in small pockets. The sound shifts to gentle bubbling, and the scent becomes rich and toasty, signaling readiness. This quick blast of top heat creates a pleasing visual contrast and adds a gooey binding element to the dish. It is important to broil briefly and watch carefully, because cheese can go from perfectly golden to burnt in seconds; keep the oven door slightly open if your broiler is intense, and pull it out once small brown spots appear.
Garnish with parsley, add extra BBQ sauce if desired, and serve hot straight from the skillet.: The final sprinkle of chopped parsley introduces a fresh, herbaceous aroma and a bright green contrast to the rich, caramelized surface. Serving the skillet hot preserves the textures and keeps the cheese stretchy, while extra BBQ sauce on the side gives guests control over sauciness. The reason this plating works is it encourages communal eating and a casual, satisfying presentation. A common mistake is letting the skillet rest too long before serving, which allows the cheese to congeal and the crisp edges to soften; serve promptly for best experience.
