Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.

Prepare the Brussels sprouts by trimming the ends and cutting each sprout in half.

Toss the sprouts in olive oil, salt, and pepper. You can also add garlic powder for a hint of extra flavor.

Arrange the Brussels sprouts in a single layer on the baking sheet, with the cut side facing down for a crispy finish.

Roast for 20-25 minutes or until the sprouts are golden brown and tender. For extra crispiness, broil for the last 2-3 minutes.

Sprinkle with Parmesan cheese before serving for a savory touch.
