Follow these easy steps to create the Juicy Greek Chicken Marinade:

1. Prepare the Chicken: Place the chicken breasts on a cutting board. Gently pound them to an even thickness using a meat mallet for consistent cooking.
2. Make the Marinade: In a bowl, whisk together the olive oil, lemon juice, minced garlic, dried oregano, dried thyme, salt, black pepper, and red wine vinegar until well combined.
3. Combine Chicken and Marinade: In a large ziplock bag or a shallow dish, add the chicken breasts. Pour the marinade over the chicken, ensuring they are completely coated.
4. Marinate: Seal the ziplock bag or cover the dish with plastic wrap. Let the chicken marinate in the refrigerator for at least 1 hour, or up to 4 hours for maximum flavor.
5. Preheat the Grill or Oven: If grilling, preheat your grill to medium-high. If baking, preheat your oven to 400°F (200°C).
6. Cook the Chicken: Remove the chicken from the marinade and let any excess drip off. Grill the chicken for 6-8 minutes on each side, or bake in the oven for 20-30 minutes until cooked through and the internal temperature reaches 165°F (75°C).
7. Rest the Chicken: After cooking, let the chicken rest for about 5 minutes to retain its juices.
8. Slice and Serve: Once rested, slice the chicken and serve with your favorite sides.
