- Make the marinade: In a large bowl or container, combine the white miso paste, gochujang, sesame oil, honey, minced garlic, and the white parts of the green onions. Mix well until smooth. 
- Marinate the chicken: Add the chicken thighs and coat evenly with the marinade. Cover and marinate in the fridge for at least 30 minutes, but overnight is best for deeper flavor. 
- To air fry: Preheat your air fryer to 380°F (193°C). 
- Place the chicken thighs skin-side up in a single layer in the air fryer basket. 
- Cook for 25–30 minutes, flipping halfway through, or until the internal temperature reaches 165°F (74°C) and the skin is crispy. 
- To bake: Preheat your oven to 400°F (200°C). 
- Place the chicken thighs on a parchment-lined baking tray or in a cast iron skillet, skin-side up. 
- Bake for 35–40 minutes, or until golden brown and cooked through (internal temp 165°F/74°C). Broil for 2–3 minutes at the end to crisp the skin. 
- Garnish and serve: Sprinkle the reserved green onion tops over the chicken before serving. Enjoy with rice, noodles, or your favorite veggies.
