Preheat your oven to 200°C (390°F).
In a large mixing bowl, combine the chicken thighs, sliced chorizo, halved baby potatoes, chopped bell peppers, onion wedges, and crushed garlic.
Drizzle the olive oil over the mixture and sprinkle in the smoked paprika, dried oregano, salt, and pepper. Toss everything together until evenly coated.
Transfer the mixture to a large baking tray, spreading it out in a single layer for even cooking.
Bake in the preheated oven for 35-40 minutes, or until the chicken is cooked through and golden brown, and the potatoes are tender.
Once done, remove from the oven and let it rest for a few minutes. Garnish with chopped fresh parsley before serving.
