Prepare the chicken: Pat the chicken breasts dry with paper towels. If they are very thick, gently pound them to an even thickness for uniform cooking.
Make the garlic herb seasoning: In a small bowl, combine garlic powder, smoked paprika, onion powder, oregano, thyme, dried parsley, salt, black pepper, and chili flakes.
Season the chicken: Rub the chicken breasts with olive oil and lemon juice. Sprinkle the garlic herb seasoning evenly over both sides, gently pressing it into the meat. For extra flavor, let the seasoned chicken rest in the refrigerator for 15–30 minutes.
Preheat the air fryer: Preheat your air fryer to 375°F (190°C) for 3–5 minutes.
Air fry the chicken: Place the seasoned chicken breasts in a single layer in the air fryer basket, leaving space between them. Air fry for 16–20 minutes, flipping halfway through. The chicken is fully cooked when the thickest part reaches an internal temperature of 165°F (74°C).
Add extra flavor: If desired, brush the cooked chicken breasts with melted butter for a glossy, flavorful finish.
Rest and serve: Remove the chicken from the air fryer and let it rest for 5 minutes before slicing. Garnish with freshly chopped parsley and serve warm.
Notes
Don’t overcook: Use a meat thermometer to prevent dry chicken.
Even thickness: Pound thicker chicken breasts so they cook evenly.
Use olive oil: Helps the seasoning stick and creates a beautifully browned exterior.
Avoid overcrowding: Leave enough space for hot air to circulate.
Let it rest: Resting helps retain the delicious juices.
