Preheat the air fryer to 380F / 195C for 3 minutes.
Combine the paprika, thyme, oregano, garlic powder, salt and black pepper in a small bowl with the olive oil. Stir or whisk together.
Peel the potatoes and dice into 1 inch pieces. Add to a large bowl and drizzle on half of the spiced oil. Toss to coat the potatoes.
Add the potato pieces into the air fryer in an even layer, with a little space between them so the air can circulate. Air fry the potatoes for 12 minutes at 380F / 195C, shaking the basket after 5-6 minutes.
Pat the chicken breasts dry with paper towel, then place them in the bowl and pour in the remaining seasoned oil. Rub the oil over the chicken breasts to coat.
If you have a dual basket air fryer add the chicken breasts to the other drawer. If you have a single drawer air fryer, use tongs to push the potatoes to one side and place the chicken breasts next to them, with space between them. Air fry the chicken and potatoes for 15-16 minutes at 380F (flipping the chicken after 10 minutes with tongs), or until the chicken has an internal temperature of 165F at its deepest point using a meat thermometer.
Let the chicken rest for 5-10 minutes, then enjoy your dinner!
