Preheat the oven to 400 degrees fahrenheit and spray a sheet pan with cooking spray. Set aside.
In a small bowl combine the olive oil, lemon zest, lemon juice, garlic, parsley, rosemary, salt, and pepper.
Cut the potatoes into 1-inch pieces and toss in a large bowl with the olive oil mixture until evenly coated.
Spread the potatoes evenly on the sheet pan and bake for 40-45 minutes, stirring them around halfway through. Serve warm.
