Preheat the air fryer to 375°F (190°C) for 5 minutes.
Pat the chicken breasts dry with paper towels.
Brush both sides of the chicken breasts with olive oil, then season with salt and black pepper evenly.
Place the chicken breasts in the air fryer basket in a single layer.
Cook the chicken breasts in the air fryer for 12 minutes, flipping halfway through at 6 minutes.
While the chicken cooks, combine the minced garlic, honey, soy sauce, and apple cider vinegar in a small bowl and mix well to create the honey garlic sauce.
After 12 minutes, check the internal temperature of the chicken breasts with a meat thermometer; it should read 165°F (74°C). If not, cook for an additional 2-3 minutes as needed.
Brush the honey garlic sauce generously over both sides of the cooked chicken breasts.
Return the chicken to the air fryer and cook for an additional 2-3 minutes at 375°F (190°C) to caramelize the sauce.
Remove the chicken breasts from the air fryer and let rest for 3 minutes before serving.
