Preheat your oven to 400°F (200°C).
Pat the chicken thighs dry with paper towels.
In a large bowl, mix olive oil, garlic powder, paprika, salt, and pepper.
Add the chicken thighs to the bowl and coat them evenly with the spice mixture.
Place the chicken thighs skin-side up on a baking sheet.
Arrange the mixed vegetables around the chicken on the baking sheet.
Roast in the preheated oven for 35-40 minutes or until the chicken reaches an internal temperature of 165°F (75°C).
Remove from the oven and let the chicken rest for 5 minutes.
Garnish with fresh parsley before serving.
Serve hot and enjoy your meal!
