Preheat your air fryer to 375°F (190°C) for a few minutes.

In a mixing bowl, combine the mashed ripe peaches, olive oil, honey, Dijon mustard, minced garlic, salt, and pepper. Mix until you have a smooth and well-incorporated peach glaze.

Place the chicken thighs in a separate bowl or zip-top bag and pour half of the peach glaze over them. Ensure that the chicken thighs are evenly coated with the glaze. Let them marinate for about 10-15 minutes to absorb the flavors.

Place the marinated chicken thighs skin-side down in the preheated air fryer basket, leaving some space between them for even cooking. Cook for about 12-15 minutes at 375°F (190°C).

After the initial cooking time, carefully flip the chicken thighs over so that they are skin-side up. Brush the remaining peach glaze generously over the top of each thigh.

Return the chicken thighs to the air fryer and continue cooking for an additional 12-15 minutes or until the internal temperature reaches 165°F (74°C) and the skin is crispy and golden brown. Cooking times may vary depending on the size of your chicken thighs and your specific air fryer model.

Remove the Peach Chicken Thighs from the air fryer and let them rest for a few minutes. This allows the juices to redistribute, ensuring tender and juicy meat. Serve your delicious Air Fryer Peach Chicken Thighs hot, garnished with fresh herbs if desired.
