Preheat oven to 400 degrees F. Cut off the brown ends of the Brussels sprouts and pull off any yellow outer leaves. Mix them in a bowl with the olive oil, salt and pepper.

Sprinkle with more kosher salt (I like these salty like French fries), and serve immediately.
Preheat oven to 400Â°F. Toss Brussels sprouts with oil, salt and pepper on a rimmed baking sheet and roast, stirring once or twice, until deep golden brown, crisp outside and tender inside, 30 to 35 minutes. The leaves that are loose will be especially brown and crispy. Transfer to a bowl and serve.
