Marinate the Chicken
In a large bowl, combine the minced garlic, olive oil, lemon juice, cumin, paprika, turmeric, Aleppo pepper, salt, and pepper. Mix well. Add the chicken to the bowl, ensuring it’s well coated in the marinade. Cover and refrigerate for at least 2 hours, or overnight for the best flavor.

Cook the Chicken
Preheat the oven to 425°F (220°C). Place the marinated chicken on a baking sheet along with the quartered red onion. Bake for 20-25 minutes, or until the chicken is cooked through and slightly crisped on the edges.

Serve
Remove from the oven and let the chicken cool for 10 minutes. Once cooled, carefully slice the chicken and arrange it on a serving dish with the red onion and juices from the baking sheet. Top with chopped parsley and enjoy!
