Preparations: 

• Preheat air fryer for 5 minutes. Meanwhile, in a large bowl, toss steak, Worcestershire sauce, pepper and 2 teaspoons salt.
• Working in batches if necessary, arrange steak in air fryer basket in a single layer. Cook 2 minutes, then flip and continue to cook until medium-rare, 1 to 2 minutes more, or to desired degree of doneness. Transfer steak to a plate and keep warm. 
• Meanwhile, in a small pot over medium heat, melt 2 tablespoons butter. Stir in garlic and remaining 1/2 teaspoon salt and cook, stirring occasionally, until sizzling and fragrant, about 1 minute. Add remaining 6 tablespoons butter and stir until melted, about 1 minute more. Remove from heat.
• Drizzle steak with half of garlic butter. Serve with remaining garlic butter alongside for dipping.
