Preheat your oven to 400 degrees f. and line a large baking tray with parchment paper.
Add the sprouts onto your prepared tray.
Drizzle with melted butter and sprinkle with pepper and parmesan cheese.
Toss well until evenly coated, then arrange them into a single layer without overlapping.
Roast in your preheated oven for 17-20 minutes, or until golden crisp, and fork tender.
Serve and enjoy!
