Chicken shawarma is a Middle Eastern dish packed with rich spices that makes a wonderful anchor for many meals, from pita sandwiches to a savory topping for rice.
In a large glass bowl, whisk together first ten ingredients. Add chicken; toss to coat. Cover; refrigerate at least 4 hours.
Meanwhile, whisk together yogurt, lemon juice and garlic. Cover; refrigerate until ready to use.
Preheat oven to 400°. Coat a loaf pan with cooking spray. Layer marinated chicken in greased 9x5-in. loaf pan, pressing down to fill. Bake until internal temperature reaches 165°, about 45-50 minutes. Let rest 10 minutes. Flip chicken onto a cutting board; slice crosswise into small pieces.
