Heat the oven to 400 degrees.
In a mixing bowl, toss the pork chops with 1 tbsp of the olive oil, the cayenne pepper, cumin, worcestershire sauce, garlic and salt and pepper to taste. Place the pork in a single layer on a parchment lined baking sheet.
Add the potatoes and onion to a large mixing bowl and toss with the remaining olive oil, rosemary, paprika and salt and pepper to taste.
Spread the potatoes and onion next to the pork on the baking sheet.
Bake for 20-25 minutes until the potatoes are tender and the meat is cooked through.
