Creating Sheet Pan Honey Mustard Chicken is straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 400°F (200°C) to ensure even cooking.
2. Prepare the Marinade: In a bowl, mix together honey, Dijon mustard, olive oil, garlic powder, onion powder, salt, and pepper until well combined.
3. Marinate the Chicken: Place the chicken breasts in a resealable plastic bag or bowl. Pour half of the marinade over the chicken, ensuring it’s evenly coated. Let it marinate for at least 30 minutes, or up to 2 hours for more flavor.
4. Prepare the Vegetables: While the chicken is marinating, wash and chop the vegetables into bite-sized pieces.
5. Arrange on Sheet Pan: Line a large baking sheet with parchment paper or aluminum foil. Place the marinated chicken breasts in the center of the pan. Arrange the broccoli florets, baby carrots, and sliced bell peppers around the chicken.
6. Drizzle Remaining Marinade: Drizzle the remaining marinade over the vegetables, making sure they are coated.
7. Bake: Place the sheet pan in the preheated oven and bake for 25-30 minutes or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C).
8. Broil for Extra Color (Optional): For a crispy finish, switch to broil for the last 2-3 minutes, keeping a close eye to prevent burning.
9. Rest the Chicken: Once cooked, remove the pan from the oven and let the chicken rest for 5 minutes before slicing.
10. Garnish and Serve: Garnish with fresh parsley if desired, and serve warm.
