In a small bowl, whisk together honey, Dijon mustard, olive oil, soy sauce, garlic powder, onion powder, salt, and pepper to create the marinade.
Place the chicken breasts in a baking dish and pour the marinade over them, ensuring they are well coated. Let them marinate for at least 15 minutes while you prepare the rice.
In a medium saucepan, bring the chicken broth to a boil. Once boiling, stir in the jasmine rice. Reduce the heat to low, cover, and let it simmer for about 15 minutes until the rice is fluffy and the liquid is absorbed.
While the rice is cooking, bake the marinated chicken in the preheated oven for 25-30 minutes or until fully cooked through (internal temperature should reach 165°F/75°C).
Remove the chicken from the oven and let it rest for 5 minutes before slicing it.
Fluff the rice with a fork and serve it on plates or in bowls, topped with the sliced honey mustard chicken.
Drizzle any remaining marinade from the baking dish over the chicken and rice.
Garnish with fresh parsley for added color and flavor.
