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 10-15 minutes depending on the size of your Brussels sprouts.
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 5-7 minutes until the sprouts are fully cooked and the breadcrumbs are toasted. Enjoy!
