In a medium mixing bowl, combine the honey, freshly squeezed lemon juice, minced garlic, soy sauce, Dijon mustard, olive oil, and a pinch of salt and freshly cracked pepper. Whisk the mixture until all ingredients are well blended, creating a flavorful marinade.
Transfer the chicken breasts to a large resealable plastic bag or a shallow dish. Pour the marinade over the chicken, ensuring that each piece is generously coated. Seal the bag or cover the dish with plastic wrap and refrigerate for at least 30 minutes, though marinating for 1-2 hours will yield a more intense flavor.
Preheat your grill or oven to 375°F (190°C) for optimal cooking.
After marination, remove the chicken from the bag or dish, allowing any excess marinade to drip off. Reserve the remaining marinade for basting during cooking.
Grilling Method: Place the chicken on the grill. Cook for approximately 6-7 minutes on each side, basting with the reserved marinade during the final minutes of cooking for added flavor.
Oven Method: Arrange the marinated chicken breasts on a baking sheet lined with parchment paper. Bake for 25-30 minutes, or until the internal temperature reaches a safe 165°F (75°C), basting with the marinade halfway through cooking.
Once fully cooked, remove the chicken from the heat and allow it to rest for about 5 minutes before slicing; this helps retain the juices.
To serve, plate the chicken and garnish with freshly chopped parsley and lemon slices to add a vibrant touch and a burst of freshness.
