Heat the oven to 400 degrees, line a sheet pan with foil, and coat the foil with cooking spray. The prepared pan helps the potatoes brown well and release more easily once the bottoms are properly roasted.

Put the potatoes in a large bowl, then add the olive oil, garlic, salt, pepper, Italian seasoning, and parmesan cheese and toss until every piece is evenly coated. You should see the seasoning and cheese distributed across the cut surfaces rather than sitting in the bottom of the bowl.

Arrange the potatoes in a single layer on the pan and roast for 35-40 minutes, then finish with parsley and serve. They’re ready when the edges look golden brown, a fork slides in easily, and the potatoes release from the pan with minimal sticking.
