1. Adjust oven rack to lowest position and heat oven to 475°F. Trim outer leaves of cauliflower and cut stem flush with bottom. Cut head into 8 equal wedges so that core and florets remain intact (see photo). Place wedges cut side down on foil or parchment-lined rimmed baking sheet. Drizzle with 2 tablespoons oil and sprinkle with salt and pepper; gently rub to evenly distribute oil and seasonings. Gently flip cauliflower and season other cut side with remaining 2 tablespoons oil, salt, and pepper.

2. Cover baking sheet tightly with foil and cook for 10 minutes. Remove foil and continue to roast until bottoms of cauliflower pieces are golden, 8 to 12 minutes. Remove sheet from oven, and using spatula, carefully flip wedges. Return sheet to oven and continue to roast until cauliflower is golden all over, 8 to 12 minutes longer. Season with salt and pepper to taste, drizzle with oil (or sauce), and serve immediately.
