Preheat your oven to 400°F (200°C).
Pat the chicken thighs dry with paper towels.
In a bowl, mix olive oil, salt, pepper, garlic powder, paprika, and thyme.
Rub the spice mixture generously over each chicken thigh.
Arrange the chicken thighs skin-side up on a baking tray.
Scatter the mixed vegetables around the chicken.
Drizzle a bit more olive oil over the vegetables and season with salt and pepper.
Bake for 35-40 minutes or until chicken is golden brown.
Check the internal temperature (165°F/75°C) for doneness.
Let the chicken rest for 5 minutes before serving, garnished with fresh herbs.
