Prepare the ingredients: Wash Brussels sprouts, remove dry leaves, and pat dry. Preheat oven to 400°F (200°C) and line a baking tray with parchment paper. Spread sprouts on the tray, ensuring they aren’t overcrowded.
Add the seasoning: Season with salt, white pepper, drizzle with olive oil, and add a few knobs of butter. Bake until golden, shaking the pan halfway through. Serve with your favorite main meal. Enjoy!
