Preheat oven to 200 Celsius (C) / 392 Fahrenheit (F).
Combine the salt, and freshly ground black pepper then pat the chicken dry and rub the mixture all over.
In a prepared oven dish, arrange the chicken thighs so that you can add the potatoes and onions later.
Add small knobs of butter under each skin, sprinkle generously with the smoked paprika then the olive oil, this will make the skin super crispy.
Transfer the chicken to the preheated oven and let them brown, remove from the oven, add the broth, organise the potatoes and onion slices between chicken thighs.
Reduce the oven’s temperature to 170 Celsius (C) / 338 Fahrenheit (F), transfer the chicken back in the oven and let it bake until the chicken is cooked through and almost falling apart.
