Perfect Roasted Brussels Sprouts are a quick and easy side to make for holiday dinners or weekday meals. The seasonings are minimal to go with any meal.
Move oven rack to upper middle position and heat oven to 500°F. Trim the ends off of 2 1/4 pounds brussels sprouts. Leave small sprouts (less than 1") whole, cut medium ones (over 1") in half, and large sprouts (more than 2") into quarters.
Toss the brussels sprouts with 3 Tablespoons olive oil, 1 Tablespoon water, 1 teaspoon kosher salt, and 1/4 teaspoon freshly ground black pepper in a large bowl. Transfer sprouts to a rimmed baking sheet and arrange them with cut sides down.
Cover baking sheet tightly with aluminum foil. Roast for 10 minutes. Sprouts will be bright green and beginning to soften. Carefully remove foil and roast for 10-12 minutes longer, until sprouts are browned and tender. Transfer to serving dish and season with additional salt and pepper to taste.
