If using an oven for the potatoes, preheat to 400℉
Cut up the chicken, then add the minced garlic, onion powder, half the chili flakes and salt, ⅔ of the mixed herbs and paprika, and just enough olive oil to help the spices coat the chicken. Mix thoroughly, then set aside.
Dice the potatoes, spray with olive oil, and mix in the garlic powder and the rest of the other spices. Air fry at 400℉ for 18-20 minutes, or bake in the oven for 20-23 minutes.
About halfway through the potato timer, add the chicken to a large pan and sauté on high heat for 5-6 minutes, until cooked through.
Lower the heat, then add the milk, cream cheese, parmesan, and extra seasoning to taste. Mix until creamy.
Once combined, add the finished potatoes and sprinkle the shredded mozzarella on top. Cover and let sit a few minutes on low heat to let the cheese melt.
