Preheat your oven to 425 degrees f. and position a rack in the center of your oven.
Place your butter into an 8x8 baking dish, then into your preheated oven for just a minute or so until it's melted.
Meanwhile, prepare the Brussels sprouts, trim them, and cut them in half.
Once the butter has melted in the bottom of your baking dish, carefully remove the dish from the oven.
In the same baking dish, add the pressed garlic, Italian seasoning, and parmesan cheese, stirring everything with a fork until well combined.
Use a silicone spatula to help you evenly spread this mixture over the entire bottom of the baking dish. This will form the crust!
Arrange your sprout halves, cut-side down onto the baking dish as shown, and gently press them to adhere to the parmesan mixture.
Season with a pinch of sea salt and freshly ground black pepper to taste.
Roast in your preheated oven for 25-30 minutes, or until golden with a crisp to the bottom.
Serve immediately and enjoy!
