Preheat the oven broiler to high. In a bowl, mix parmesan cheese, panko breadcrumbs, melted butter, minced garlic, and chopped parsley.
Season the steaks with salt, black pepper, and garlic powder. Heat a cast-iron skillet over high heat and add olive oil.
Sear the steaks for 3-4 minutes per side until a deep crust forms. Remove from heat.
Spread the parmesan mixture evenly over the top of each steak.
Place under the broiler for 2-3 minutes until the topping is golden brown and crispy.
Let the steaks rest for 5 minutes before slicing. Garnish with extra parsley and serve immediately.
