Preheat the oven to 375°F (190°C).
In a large bowl combine the olive oil, minced garlic, kosher salt, black pepper, dried oregano, crushed red pepper, dried thyme, lemon juice (from one lemon) and lemon zest.
Add the chicken thighs to the bowl and toss well to coat all pieces evenly with the marinade.
Place the chicken thighs skin-side up in a cast iron skillet or baking dish, spacing them slightly apart.
Toss the lemon wedges in the remaining marinade and tuck them between the chicken pieces in the skillet.
Roast in the preheated oven for 35–40 minutes, until the skin is browned and crispy and the internal temperature reaches 165°F (74°C).
