Pat the chicken thighs dry with paper towels. This helps them crisp up nicely.
In a small bowl, mix together the minced garlic, olive oil, dried thyme, dried rosemary, onion powder, smoked paprika, and sea salt. Rub this mixture all over the chicken thighs, making sure to get some under the skin for maximum flavor.
Place the seasoned chicken thighs on a baking sheet or in a roasting pan. Pour the chicken broth into the pan around the chicken thighs (not directly on top of them) to keep the meat juicy during roasting.
Roast in the preheated oven at 375°F (190°C) for 35-40 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the skin is crispy.
Let the chicken thighs rest for a few minutes before serving to allow the juices to redistribute. Serve with your favorite AIP-compliant side dishes.
