Marinate the Steak: In a small bowl, combine the olive oil, minced garlic, salt, pepper, dried rosemary, dried thyme, and the zest and juice of one lemon. Place the hanger steak in a dish or zip-top bag and pour the marinade over it. Let it marinate in the refrigerator for at least 2 hours, or up to overnight.

Prepare for Cooking: Remove the steak from the refrigerator about 30 minutes before cooking to let it come to room temperature. This helps it cook more evenly.

Pan-Cooked Method: Heat a large skillet over medium-high heat. Add the butter and let it melt. Add the steak and cook for about 4-5 minutes on each side for medium-rare, or until it reaches your desired level of doneness.

Broiled Method: Position your oven rack about 6 inches from the top and preheat your broiler. Place the steak on a broiler pan and broil for about 4-5 minutes on each side for medium-rare, or until it reaches your desired level of doneness.

Grilled Method: Preheat your grill to high heat. Grill the steak for about 4-5 minutes on each side for medium-rare, or until it reaches your desired level of doneness.

Rest and Serve: Regardless of the method used, let the steak rest for about 5 minutes after cooking to let the juices redistribute. Slice it against the grain and serve.
