Toss the sliced potatoes with 1 tbsp olive oil, 1 tsp smoked paprika, garlic granules, and oregano. Cook for 7–8 minutes at 200°C, shaking halfway.
Pat the chicken thighs dry, brush with olive oil, and season with the remaining spices. Add them to the air fryer on top of the potatoes. Cook for 15 minutes, turning the chicken halfway.
Add the peppers, onions, and chorizo to the basket for the last 10 minutes. Toss to combine.
Ensure the chicken reaches an internal temperature of 75°C. Serve immediately.
