01 - Preheat oven to 425°F. Line a baking sheet with foil and position a wire rack on top to promote air circulation for crispy skin.
02 - Combine olive oil, salt, pepper, garlic powder, paprika, thyme, onion powder, oregano, and chili powder in a small bowl. Mix thoroughly to form a uniform paste.
03 - Pat chicken leg quarters completely dry with paper towels, removing excess moisture for better crisping. Arrange skin-side up on the wire rack.
04 - Rub seasoning mixture evenly over both sides of each quarter. Lift skin gently and work seasoning 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 5 minutes to redistribute juices. Garnish with chopped parsley and lemon wedges if desired before serving.
