Follow these simple steps to create your delicious Oven Baked Greek Chicken Thighs:

1. Preheat the Oven: Preheat your oven to 425°F (220°C).
2. Make the Marinade: In a bowl, whisk together olive oil, minced garlic, lemon juice, oregano, salt, black pepper, paprika, and onion powder.
3. Marinate the Chicken: Place the chicken thighs in a large zip-top bag or a bowl. Pour the marinade over the chicken, ensuring each piece is well coated. Seal the bag or cover the bowl and refrigerate for at least 1 hour.
4. Prepare for Baking: Line a baking dish with parchment paper or lightly grease it with cooking spray.
5. Arrange the Chicken: Remove the chicken from the marinade and place it skin-side up in the prepared baking dish. Pour any remaining marinade over the chicken.
6. Bake the Chicken: Place the baking dish in the preheated oven and bake for 40-45 minutes, or until the chicken reaches an internal temperature of 165°F (75°C) and the skin is golden and crispy.
7. Rest the Chicken: Once cooked, remove the chicken from the oven and let it rest for 5-10 minutes before serving. This helps the juices redistribute, keeping the meat tender.
8. Garnish: Sprinkle chopped fresh parsley over the chicken for a pop of color and freshness.
9. Serve: Serve the chicken with lemon wedges on the side for an extra burst of flavor.

These steps will guide you in creating a mouthwatering dish that is sure to impress your family and friends.
