Wash and peel the potatoes, removing any dirt or imperfections. Cut them into approximately 1-inch cubes, keeping the pieces uniform for even cooking. Transfer the cubed potatoes to a mixing bowl and toss with olive oil until lightly coated. Sprinkle with salt, pepper, garlic powder, and paprika. Mix thoroughly to distribute the seasonings evenly.
Preheat the air fryer to 400°F (200°C). Arrange the seasoned potatoes in the air fryer basket in an even layer, allowing hot air to circulate around them. Cook for approximately 20 minutes, shaking the basket halfway through. Check with a fork to ensure the potatoes have golden exteriors and tender centers. Alternatively, roast the potatoes in a preheated oven at 400°F (200°C) on a parchment-lined baking sheet for 25–30 minutes, turning halfway through.
While the potatoes cook, cut the chicken breasts into approximately 1-inch cubes. Place the chicken in a medium mixing bowl and season with 1/2 teaspoon salt, 1/2 teaspoon black pepper, 1 teaspoon paprika, 1 teaspoon onion powder, and 1 teaspoon Italian seasoning. Toss thoroughly until every chicken piece is evenly coated with the seasoning mixture.
Heat a large skillet over medium-high heat and add 2 tablespoons of butter. Once the butter melts and begins to bubble, arrange the seasoned chicken pieces in a single layer. Cook for approximately 6–8 minutes, turning occasionally to develop an evenly browned exterior. Check that the chicken reaches an internal temperature of 165°F (74°C) using a meat thermometer. Reduce the heat slightly if the exterior browns too quickly.
Once the chicken is fully cooked, add 2 tablespoons of minced garlic to the skillet. Cook for approximately 1–2 minutes, stirring frequently until fragrant without allowing the garlic to burn. Pour in the Buffalo Wild Wings Garlic Parmesan Sauce, adjusting the quantity to your preferred consistency. Stir gently to coat every piece of chicken, then simmer for another 1–2 minutes until the sauce is heated through and slightly thickened.
When the potatoes are golden and tender, transfer them directly into the skillet with the garlic Parmesan chicken. Gently toss the chicken and potatoes together using a spatula until everything is evenly coated in the creamy sauce. Stir carefully to keep the potato cubes intact and distribute the chicken and potatoes evenly throughout the skillet.
Sprinkle shredded mozzarella cheese evenly over the chicken and potatoes. For a soft, melted topping, cover the skillet with a lid and allow the residual heat to melt the cheese for approximately 2–3 minutes. Alternatively, if using an oven-safe skillet, place it under the broiler on high for 2–3 minutes until the cheese becomes golden and bubbly. Watch carefully to prevent burning. Serve warm while the cheese is melted and the garlic Parmesan sauce is creamy.
