Prepare the Marinade: Mix together honey, olive oil, apple cider vinegar, minced garlic, dried oregano, red pepper flakes, salt, and pepper in a medium bowl. Whisk until all ingredients are well integrated.
Marinate the Chicken: Place chicken breasts into a large resealable plastic bag or shallow dish and pour the marinade over them. Seal the bag tightly or cover the dish with plastic wrap and refrigerate for at least 30 minutes; ideally allow it to marinate for 2-4 hours.
Prepare the Feta Mixture: In a small bowl, combine crumbled feta cheese with a drizzle of olive oil and a pinch of salt and black pepper. Gently mix and set aside.
Bake the Chicken: Preheat your oven to 400°F (200°C). Remove the marinated chicken from refrigeration, discard excess marinade, and place in a baking dish. Spoon the prepared feta mixture over each breast.
Cook Until Perfect: Bake for about 25-30 minutes or until the internal temperature reaches 165°F (75°C) and the feta cheese is golden brown and bubbly. Broil for an additional 2-3 minutes for extra crispiness.
Serve With Style: Allow the baked chicken to rest for about five minutes. Arrange on a serving platter alongside greens or roasted vegetables, garnish with freshly chopped parsley, and offer lemon wedges.
