Creating these incredible baked chicken legs is simple if you follow these easy steps:

1. Preheat the Oven: Preheat your oven to 425°F (220°C) to ensure the chicken cooks evenly and crisps up nicely.
2. Prepare Chicken Legs: Rinse the chicken legs under cold water and pat them dry with paper towels. This helps the skin become crispy.
3. Mix Seasoning: In a small bowl, combine the olive oil, garlic powder, onion powder, paprika, oregano, salt, black pepper, and cayenne pepper (if using). Mix well to create a flavorful marinade.
4. Coat Chicken: Place the chicken legs in a large bowl or a resealable plastic bag. Pour the marinade over the chicken, ensuring each piece is generously coated.
5. Arrange on Baking Sheet: Line a baking sheet with parchment paper or aluminum foil for easy cleanup. Place the chicken legs on the sheet, ensuring they are spaced apart for even cooking.
6. Bake: Place the baking sheet in the preheated oven and bake for 40-45 minutes. Halfway through, flip the chicken legs to ensure they cook evenly.
7. Check Doneness: Use a meat thermometer to check the internal temperature. It should reach 165°F (74°C) at the thickest part of the leg.
8. Crisp Up Skin: If you desire extra crispy skin, broil the chicken legs for an additional 2-3 minutes at the end of cooking. Keep a close watch to avoid burning.
9. Rest: Remove the chicken from the oven and let it rest for 5-10 minutes. This allows the juices to redistribute, ensuring moist meat.
10. Garnish: Sprinkle chopped fresh parsley over the chicken legs for a burst of color and flavor before serving.

Following these steps will guide you to create mouthwatering baked chicken legs that everyone will enjoy!
