Preheat your oven to 375°F (190°C).
In a bowl, whisk together honey, Dijon mustard, olive oil, minced garlic, salt, and pepper.
Place the chicken breasts in a baking dish.
Pour the honey mustard mixture over the chicken, ensuring each piece is well coated.
Bake in the preheated oven for 20-25 minutes until the chicken is cooked through.
Use a meat thermometer to check that the internal temperature reaches 165°F (75°C).
Baste the chicken with the sauce halfway through cooking for extra flavor.
Once done, remove from the oven and let it rest for 5 minutes.
Garnish with fresh thyme before serving.
Serve warm with your choice of sides.
