Preheat the oven to 425°F. Line a large rimmed baking sheet with parchment paper or lightly grease it with cooking spray.
Add the baby potatoes to the prepared baking sheet. Toss with 2 tablespoons olive oil, ½ teaspoon garlic powder, ½ teaspoon smoked paprika, ½ teaspoon Italian seasoning, if using, ½ teaspoon salt, and ¼ teaspoon black pepper.
Arrange the potatoes cut-side down in a single layer. Bake for 25 minutes.
While the potatoes bake, pat the pork chops dry with paper towels. Rub them with the remaining 1 tablespoon olive oil.
Season both sides of the pork chops with the remaining ½ teaspoon garlic powder, ½ teaspoon smoked paprika, ½ teaspoon Italian seasoning, if using, ¼ teaspoon salt, and ¼ teaspoon black pepper.
Remove the baking sheet from the oven and turn the potatoes. Arrange the pork chops between the potatoes, leaving a little space around each chop.
Return the pan to the oven and bake for 7–10 minutes, or until the potatoes are golden and fork-tender and the pork chops reach an internal temperature of 145°F. Begin checking the pork chops after 7 minutes to prevent overcooking.
Transfer the pork chops to a plate and let them rest for 3–5 minutes.
Garnish the pork chops and potatoes with chopped fresh parsley and serve with lemon wedges, if desired.
