Preheat your oven to 400 degrees. Place the Brussels sprouts on a half sheet pan. Drizzle with olive oil, then salt and pepper to taste.
Place in the oven and roast until the sprouts are just starting to brown, about 15 minutes.
Mix together the Parmesan cheese, Panko, and garlic powder in a mixing bowl. Remove the Brussels sprouts from the oven and toast them into the bowl. Mix to combine.
Put the sprouts back on the sheet pan and roast for another 7-9 minutes until the sprouts are fully cooked and the breadcrumbs are toasted. Enjoy!
