Creating Honey Mustard Sheet-Pan Chicken is a straightforward process. Follow these simple steps to make your meal:

1. Preheat the Oven: Begin by preheating your oven to 425°F (220°C). This high temperature will help the chicken skin get crispy.
2. Make the Marinade: In a small bowl, whisk together the Dijon mustard, honey, olive oil, garlic powder, onion powder, salt, and pepper until well combined.
3. Prepare the Chicken: Place the chicken thighs in a large bowl. Pour the honey mustard marinade over the chicken, ensuring each piece is well coated.
4. Prepare the Vegetables: Chop your mixed vegetables into bite-sized pieces. You can use any combination of vegetables you like.
5. Arrange on the Pan: On a large baking sheet, place the marinated chicken thighs in the center. Surround them with the chopped vegetables.
6. Drizzle Extra Marinade: If there’s any leftover marinade, drizzle it over the vegetables for added flavor.
7. Bake: Place the baking sheet in the preheated oven. Bake for 30-35 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the vegetables are tender.
8. Broil for Crispiness (optional): For an extra crispy skin, switch your oven to broil for the last 2-3 minutes, watching closely to avoid burning.
9. Garnish and Serve: Once cooked, remove the pan from the oven and let it rest for a few minutes. Garnish with fresh parsley if desired.

Following these steps will lead you to a delicious and visually appealing meal that will impress everyone at your dinner table.
