1. Preheat the oven to 400°F. Place a baking sheet in the oven to heat up. Trim the bottom of the Brussels sprouts and then slice in half from top to bottom.

2. Place the Brussels sprouts in a large bowl and add the olive oil, salt, pepper, Italian seasoning, garlic, and Parmesan cheese shreds. Gently toss to coat the sprouts.

3. Carefully remove the baking sheet from the oven and spread the Brussels sprouts over it, cut-side down, in one layer.

4. Return the baking sheet to the center rack and bake for 25-30 minutes, or until golden brown. Serve while still hot.
