Hanger Steak with Shallots
- 1/2 cup extra-virgin olive oil
- 1/4 cup sherry vinegar
- 2 garlic cloves, crushed
- 4 teaspoons Dijon mustard, plus more for serving
- 1 tablespoon Worcestershire sauce
- 1 1/2 pounds hanger steak
- 5 medium shallots, halved or quartered
- Coarse salt and freshly ground pepper
Whisk together 1/4 cup oil, the vinegar, garlic, mustard, and Worcestershire sauce in a large glass dish. Place steak in dish; turn to coat with marinade. Let steak marinate, turning once, 20 minutes.
Heat 2 tablespoons oil in a large skillet over medium-high heat. Add shallots; cook, stirring often, until just golden, 2 to 3 minutes. Reduce heat to medium-low. Season with salt. Cook, adding 1/4 cup water in batches as needed to keep shallots from sticking, until tender and caramelized, 15 to 18 minutes.Transfer shallots to a plate.
Wipe out skillet. Heat 2 tablespoons oil over medium-high heat. Remove steak from marinade; pat dry. Season with salt and pepper. Cook steak, turning once, until an instant-read thermometer registers 140 degrees (for medium-rare), 10 to 12 minutes per side. Tent with foil; let stand at room temperature 10 minutes. Season with pepper.
Meanwhile, wipe out skillet; reheat shallots over medium heat. Thinly slice steak. Serve with shallots and mustard.
