Preheat the oven to 400 F
Wash and pat dry chicken thighs. Place in a large baking dish and season with salt and pepper. Let marinate for 30 minutes. The brine will help to get juicier chicken.
Mix garlic, thyme, olive oil and butter together in a small bowl.
Rub chicken thighs with the mixture.
Put thyme sprigs around thighs and transfer in the oven.
Bake for 40 minutes by basting with pan juices halfway through cooking.
Remove from the oven and serve with mashed potato and pan juices.
ENJOY!
