Preheat your oven to 400°F and prepare a baking sheet by lining it with parchment paper. Arrange the broccoli florets on the prepared baking sheet. Drizzle them generously with extra-virgin olive oil, then season with sea salt and freshly ground black pepper. Toss everything together to ensure the florets are evenly coated.

Spread the broccoli out in a single layer on the baking sheet. Place the sheet in the oven and roast for 15 to 22 minutes, or until the edges of the broccoli are nicely browned and crisp. For a touch of heat, sprinkle with red pepper flakes before serving if you like. Enjoy your perfectly roasted broccoli as a delightful side dish!
