Creating the Sheet Pan Dinner with Chicken, Veggies, and Potatoes is easy when you follow these simple steps:

1. Preheat the Oven: Begin by preheating your oven to 425°F (220°C).
2. Prepare the Pan: Line a large sheet pan with parchment paper or lightly grease it with cooking spray.
3. Season the Chicken: In a small bowl, mix together olive oil, garlic powder, paprika, thyme, rosemary, salt, and pepper. Rub this mixture all over the chicken pieces.
4. Prepare the Vegetables: In a large bowl, combine the diced potatoes and mixed vegetables. Drizzle with a bit of olive oil, salt, and pepper, and toss to coat evenly.
5. Arrange on the Sheet Pan: Place the seasoned chicken in the center of the sheet pan. Surround it with the potato and vegetable mixture, spreading everything out evenly.
6. Bake: Place the sheet pan in the preheated oven and bake for 35-40 minutes or until the chicken is cooked through and the potatoes are tender. The chicken should reach an internal temperature of 165°F (75°C).
7. Broil for Crispiness: For an extra crispy finish, turn on the broiler for the last 2-3 minutes, watching closely to prevent burning.
8. Garnish: Remove from the oven, let cool for a few minutes, and sprinkle with fresh parsley if desired.

These straightforward steps will guide you in creating this incredible sheet pan dinner effortlessly.
