Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper or spray with cooking spray.
In a large bowl, toss the potatoes, carrots, and onion with 2 tablespoons olive oil, 1 teaspoon Italian seasoning, salt, and pepper. Spread vegetables evenly on the baking sheet.
Pat pork chops dry and rub both sides with remaining 1 tablespoon olive oil. Season with remaining Italian seasoning, garlic powder, paprika, salt, and pepper.
Nestle the pork chops among the vegetables on the sheet pan. Bake for 25-30 minutes, or until pork chops reach an internal temperature of 145°F and vegetables are tender and golden.
Let pork chops rest for 5 minutes before serving. Plate each pork chop with a generous helping of roasted vegetables and enjoy!
