Preheat the Oven: Set your oven to 400°F (200°C) for perfectly crispy Brussels sprouts.
Prepare the Brussels Sprouts: Slice each Brussels sprout in half lengthwise, from top to stem, aiming to cut through the largest outer leaf for a clean slice.
Prep the Baking Sheet: Lightly oil a baking sheet, then sprinkle half the salt and pepper over the oiled surface.
Arrange the Sprouts: Place the halved Brussels sprouts cut-side down on the baking sheet.
Add More Oil and Seasoning: Drizzle a little extra oil over the Brussels sprouts, then sprinkle the remaining salt and pepper evenly across them.
Roast: Place the baking sheet in the preheated oven and roast for 35-40 minutes. The Brussels sprouts should be browned and crispy on the cut side, with the tops slightly softened and caramelized.
Serve and Enjoy: These Brussels sprouts are delicious as-is, but if you’d like to add extra flavor, toss them in a sauce like honey-sriracha or maple-bourbon, or serve with a side of ranch for dipping.
