In a large bowl or ziplock bag, combine the chicken thighs, yogurt, lemon juice, garlic, spices and oil. Mix until fully combined and all the chicken is coated.
Lay chicken in a large baking dish and bake uncovered for 30-35 minutes or until chicken is charred on the outside. Remove from oven and cool for 5-10 minutes before slicing.
Serve chicken in pita bread along with shawarma sauce and veggies or on a salad.
