Preheat your oven to 400°F (200°C).
Pat the chicken breasts dry with paper towels and season both sides with salt and black pepper.
In an oven-safe skillet, heat the olive oil over medium-high heat. Once hot, add the chicken breasts and sear for about 5 minutes on each side until golden brown.
While the chicken is cooking, in a small bowl, mix together the feta cheese, honey, red pepper flakes, and lemon juice until well combined.
Once the chicken is seared, remove the skillet from heat and spread the feta mixture evenly over the top of each chicken breast.
Transfer the skillet to the preheated oven and bake for 20-25 minutes, or until the chicken is cooked through (internal temperature should reach 165°F).
Remove from the oven and let rest for 5 minutes. Garnish with chopped parsley before serving.
