Preheat Oven Start by preheating your oven to 400°F (200°C). Preheating ensures even cooking and crispy skin on the chicken.
Prepare the Chicken In a large mixing bowl, combine the chicken thighs with olive oil, garlic powder, onion powder, paprika, salt, and pepper. Toss until the chicken is evenly coated with the seasoning.
Arrange on Baking Sheet Line a large baking sheet with parchment paper or foil for easy cleanup. Place the seasoned chicken thighs on one side of the baking sheet.
Add the Vegetables On the other side of the baking sheet, arrange the mixed vegetables. Drizzle a little olive oil over the veggies and sprinkle with salt and pepper. Toss to combine.
Bake Place the baking sheet in the preheated oven and bake for about 30-35 minutes. The chicken is done when it reaches an internal temperature of 165°F (74°C) and the juices run clear.
Serve Once cooked, remove the baking sheet from the oven. Let the chicken rest for a few minutes before serving. Garnish with fresh herbs if desired, and enjoy your meal!
