In a small bowl, whisk together the Dijon mustard, honey, olive oil, garlic powder, paprika, salt, and black pepper until smooth. This will be your flavorful glaze.
Step 2: Coat the Chicken
Pat the chicken breasts dry with a paper towel, then place them in a shallow dish. Pour the marinade over the chicken, making sure each piece is fully coated. Let it sit for at least 10 minutes (or up to 30 minutes for deeper flavor).
Step 3: Preheat the Air Fryer
Set your air fryer to 375°F (190°C) and let it preheat for about 3 minutes. This ensures even cooking and a crispy exterior.
Step 4: Cook the Chicken
Place the chicken breasts in the air fryer basket in a single layer, leaving space between them for air circulation. Cook for 12-15 minutes, flipping halfway through, until the internal temperature reaches 165°F (74°C).
