01 - Preheat oven to 425°F. Line a baking sheet with foil and place a wire rack on top for optimal air circulation and crisping.
02 - Combine olive oil, kosher salt, black pepper, garlic powder, paprika, dried thyme, onion powder, dried oregano, and chili powder in a small bowl. Mix thoroughly to create a uniform paste.
03 - Pat chicken leg quarters completely dry with paper towels to ensure crispy skin. Arrange pieces skin-side up on the wire rack.
04 - Rub seasoning mixture evenly over both sides of each quarter, lifting skin gently to season underneath for maximum flavor penetration.
05 - Roast for 40-50 minutes until skin is crispy and deep golden brown. Verify internal temperature reaches 175°F at the thickest part without touching bone.
06 - Let chicken rest for 5 minutes to allow juices to redistribute. Garnish with chopped fresh parsley and lemon wedges before serving.
