Make the marinade. In a large bowl, combine the lemon juice, lemon zest, olive oil, salt, dried oregano, and garlic cloves. Add the chicken thighs and toss to evenly coat. Refrigerate and marinate for 1 Hour, or up to 12 Hours.
Preheat the Air Fryer to 385°F / 195°C. Place chicken in the air fryer skin side up and cook for 15-16 Minutes, or until the skin is golden brown. Set aside.
In a large mixing bowl, toss together the potatoes, lemon zest, lemon juice, zucchini, red onion slices, and quartered lemons.
Place in the air fryer basket and Air Fry at 385°F / 195°C for another 15 Minutes, or until lightly golden and fragrant. Serve alongside chicken with a sprinkle of feta. Enjoy!
