Coat the fennel wedges in a mixing bowl with olive oil, salt, and pepper. Make sure they are well-covered to enhance flavor and promote that beautiful caramelization.
Arrange the seasoned fennel cut-side down on a parchment-lined baking sheet. This helps to maximize browning and prevent sticking.
Mix Parmesan, breadcrumbs, and garlic powder in a separate bowl for the topping. The combination creates that flavorful, crispy layer everyone loves.
Sprinkle the cheese mixture evenly over each fennel wedge. Feel free to be generous here—the more, the merrier when it comes to that golden crust!
