01 - In a large bowl, whisk together tahini, olive oil, lemon juice, zaatar, garlic, cumin, smoked paprika, salt, and pepper until smooth and well combined.
02 - Pat chicken thighs dry with paper towels. Add chicken to the marinade, turning to coat thoroughly. Cover and marinate in the refrigerator for at least 1 hour, up to 8 hours for deeper flavor development.
03 - Preheat oven to 400°F. Line a baking sheet with parchment paper or foil for easy cleanup.
04 - Arrange marinated chicken thighs skin side up on the prepared baking sheet. Spoon any extra marinade over the top.
05 - Roast for 30–35 minutes, or until the skin is golden, lightly crisped, and the internal temperature reaches 175°F.
06 - For extra crispiness, broil on high for 2 minutes at the end of roasting time.
07 - Remove from oven and let rest for 5 minutes. Garnish with chopped parsley, toasted sesame seeds, and serve with lemon wedges.
