Heat oven to 425°F. Line a large baking sheet with aluminum foil.
In a small bowl, mix smoked paprika, garlic powder, Italian seasoning, ½ teaspoon salt, and ¼ teaspoon pepper. Pat pork chops dry with paper towels, rub with 1 tablespoon olive oil, and coat evenly with seasoning mix.
In a large bowl, toss the broccoli, cauliflower, zucchini, and bell pepper with the remaining 1 tablespoon olive oil, ½ teaspoon salt, and ¼ teaspoon pepper. Spread veggies evenly on the sheet pan.
Make space in the center of the sheet pan and place pork chops in the middle. Roast for 10 minutes.
Flip pork chops and stir veggies. Roast for another 4–8 minutes*, or until pork chops reach 145°F internally and veggies are tender.
Notes
*Thinner pork chops may take less time to cook. Use a meat thermometer for best results.
If the chops are ready before the veggies, move them to a plate, cover, and let them rest while the veggies go back in the oven until tender.
