Preheat your grill or air fryer to 375°F (190°C).
Pat the chicken breasts dry with paper towels—no one wants soggy chicken.
In a small bowl, mix together the olive oil, minced garlic, Italian seasoning, salt, and pepper.
Brush this garlicky goodness over the chicken, coating both sides like you mean it.
Sprinkle the grated Parmesan generously on top of each piece.
Place chicken in the air fryer basket or on the grill. Don’t overcrowd.
Cook for 16-18 minutes, flipping once halfway through. The chicken should hit 165°F internally.
Let it rest for 5 minutes before slicing. Optional: Sprinkle with chopped parsley to make it look like you really tried.
