Preheat your air fryer to 200°C (390°F) so it's ready to cook the chicken evenly and quickly.
Pat the chicken breasts dry with paper towels to remove excess moisture, helping them crisp up better.
In a small bowl, mix together paprika, garlic powder, salt, and black pepper to create your seasoning blend.
Rub the spice mixture all over each chicken breast, ensuring an even coating for maximum flavor.
Brush or spray the chicken breasts lightly with olive oil to help the spices stick and promote crispiness.
Place the seasoned chicken breasts in the air fryer basket, making sure they are not touching to allow proper air circulation.
Cook the chicken for 18-20 minutes, flipping halfway through, until the exterior is golden brown and the internal temperature reaches 75°C (165°F).
Use a meat thermometer to check the internal temperature, ensuring the chicken is fully cooked and juicy inside.
Once cooked, transfer the chicken to a plate and let it rest for 5 minutes to retain its juices.
Squeeze fresh lemon juice over the chicken if desired, adding brightness and flavor.
Slice the chicken breasts and serve while hot, enjoying the crispy exterior and tender interior.
