Preheat your oven to 425°F (220°C).
Pat the chicken leg quarters dry with paper towels and place them on a large baking sheet or roasting pan.
Drizzle the avocado oil over the chicken and rub it evenly to coat.
Season generously with kosher salt, black pepper, smoked paprika, garlic powder, and dried oregano.
Optionally, add lemon or orange zest, crushed red pepper flakes, za’atar, or harissa paste for extra flavor.
Arrange the chicken pieces skin-side up on the baking sheet, leaving space between each piece for even cooking.
Roast in the preheated oven for 35-45 minutes or until the internal temperature of the chicken reaches 165°F (74°C) and the skin is golden and crispy.
Remove the chicken from the oven and let it rest for 5 minutes before serving.
