Step 1: Prepare the Marinade

1. In a small bowl, whisk together the Dijon mustard, honey, lemon juice, minced garlic, thyme, paprika (if using), salt, and black pepper. Adjust the sweetness or tanginess to taste by adding more honey or mustard.

Step 2: Marinate the Chicken

1. Pat the chicken dry with paper towels to help the marinade adhere better.
2. Place the chicken in a resealable plastic bag or a shallow dish. Pour the marinade over the chicken, ensuring each piece is evenly coated.
3. Seal the bag or cover the dish with plastic wrap and refrigerate for at least 30 minutes, or up to 4 hours for deeper flavor.

Step 3: Preheat the Oven

1. Preheat your oven to 375°F (190°C). Lightly grease a baking dish or line it with parchment paper for easy cleanup.

Step 4: Arrange and Bake the Chicken

1. Arrange the marinated chicken in the prepared baking dish, leaving space between each piece for even cooking. Pour any leftover marinade over the chicken.
2. Bake in the preheated oven for 30-35 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) when measured in the thickest part.

Step 5: Broil for a Golden Finish

1. For a caramelized glaze, switch your oven to broil during the last 2-3 minutes of cooking. Keep a close eye on the chicken to prevent burning.

Step 6: Rest and Serve

1. Remove the chicken from the oven and let it rest for 5 minutes to retain its juices.
2. Garnish with chopped parsley and lemon slices before serving. Pair with your favorite side dishes and enjoy!
