Preparation

Step 1

1. Melt butter in a 12" skillet over medium-high heat. Add garlic and onions; cook until slightly caramelized, 12-–15 minutes, and transfer to a bowl. Whisk in coffee, soy, Worcestershire, vinegar, chile flakes, oregano, and salt. Reserve 1 cup marinade. Add steak to bowl; cover with plastic wrap and refrigerate overnight.

2. Heat a charcoal grill or set a gas grill to high; bank coals or turn burner off on one side. Remove steak from marinade and grill, flipping once, until browned, about 10 minutes. Strain some marinade and reduce on stove as steak cooks/rests. Using a brush, baste with reserved marinade, turning as needed until cooked to desired doneness, 15–20 minutes for medium rare. Rest steak 10 minutes; slice thinly on the bias.
