Preheat your oven to 400ºF. Prepare a large rimmed baking sheet.
In a large bowl, combine green beans with olive oil, minced garlic, parmesan, bread crumbs, black pepper, and Italian seasoning and toss to combine.
Spread the prepared green beans on the baking sheet and roast for 15-20 minutes, stirring halfway through. Remove roasted parmesan green beans from the oven, transfer to a serving plate and serve immediately, garnished with fresh chopped parsley.
