To make Brussels sprouts, start by preheating your oven to 400ºF. Trim the stems of the Brussels sprouts and cut each one in half from top to bottom.

If desired, prepare a large baking sheet by lining it with parchment paper.

Dry the Brussels sprouts with paper towels and transfer them to a spacious bowl.

Add melted butter, Italian seasoning, garlic, Parmesan cheese, salt, and pepper. Gently toss the ingredients to ensure the Brussels sprouts are evenly coated.

Arrange the seasoned Brussels sprouts on the prepared baking sheet, ensuring they form a single layer.

Roast the Parmesan-coated Brussels sprouts on the center oven rack for about 25 to 30 minutes, adjusting the time as needed based on your oven. The goal is for the vegetables to turn a lovely golden brown.
