Start by seasoning your chicken pieces with salt and pepper. Heat olive oil in an ovenproof skillet and sear the chicken, skin-side down, until golden brown. Flip and cook the other side for 1–2 minutes, then remove and set aside.
Lower the heat and toast cumin seeds lightly, being careful not to burn them. Melt butter, add garlic, then pour in chicken stock and fresh orange juice. Simmer for 2 minutes while scraping the skillet’s brown bits for extra flavor.
Return the chicken to the skillet, skin side up, and arrange orange slices, thyme, onion, and red pepper flakes around it. Cover with the lid and bake for 60 minutes, then remove the lid and bake for another 15 minutes to crisp the skin.
Check seasoning and adjust with salt and pepper. Garnish with fresh parsley or thyme before serving. The chicken should be tender and fragrant with a beautiful caramelized color.
