Preheat your oven to 400F and move the rack to the top third of the oven. This is crucial for achieving that perfect golden-brown finish on your chicken.
Place the chicken breasts side-by-side in a 9×13 baking dish. It’s important to give them a bit of space so they cook evenly.
Sprinkle the garlic powder and salt & pepper over the chicken. Don’t be shy with the seasoning; it adds so much flavor!
Once the oven has been preheated, bake the chicken for 10 minutes, uncovered. This helps to seal in the juices and gives a nice initial cook.
Meanwhile, whisk together the sauce ingredients in a bowl: honey, Dijon mustard, chicken broth, and cornstarch. It should turn into a smooth, glossy mixture.
Take the chicken out of the oven and pour the sauce over the top, ensuring each piece is nicely coated.
Return it to the oven and bake uncovered for another 15 to 20 minutes, or until the chicken reaches 165F internally. This step allows the sauce to caramelize and the flavors to meld.
Once the chicken is cooked through, remove it from the oven. Spoon the sauce over the top again for extra flavor. Let it rest for 5 minutes before serving.
Sprinkle with chopped parsley if desired, adding a pop of color and freshness to your dish.
Serve hot and enjoy every bite of your Easy Baked Honey Mustard Chicken!
