Steps
1. Preheat your oven to 375°F (190°C).
2. In a small bowl, mix the Dijon mustard, honey, olive oil, salt, and pepper until well combined.
3. Place the chicken breast in a baking dish and brush the honey mustard mixture generously over the top.
4. If using, add the fresh thyme on top of the chicken for extra flavor.
5. Bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through and juices run clear.
6. Remove from the oven, let it rest for a few minutes, then slice and serve.
