Instructions

1. 1

   Whisk together 1/2 cup coffee liqueur, espresso powder, 3/4 teaspoon chili powder, oregano, sugar, and 1/4 teaspoon each salt and pepper in a bowl. Pat steak dry with paper towels and transfer to a large resealable plastic bag. Add coffee marinade and seal bag, turning to coat. Chill at least 1 hour or up to overnight.

2. 2

   When ready to cook, let steak and marinade sit at room temperature about 30 minutes. Remove steak from marinade and pat dry; discard marinade. Sprinkle steak with 1/4 teaspoon pepper and 1/4 teaspoon salt.

3. 3

   Preheat grill to medium-high heat. Lightly oil grill grates.

4. 4

   Grill steak, uncovered, turning once halfway through, 8 to 10 minutes. An instant-read thermometer inserted into the center should read 130 degrees F (54 degrees C). Let rest about 10 minutes before thinly slicing.

5. 5

   Meanwhile, heat oil in a skillet over medium heat. Add shallot and garlic; cook, stirring frequently, until fragrant, about 2 minutes. Add remaining 3/4 teaspoons chili powder and 1/4 teaspoons each salt and pepper. Cook until fragrant, about 30 seconds. Stir in remaining 1/2 cup coffee liqueur.

6. 6

   Simmer over medium heat until liquid has reduced by half, 2 to 3 minutes. Add beef broth; cook until sauce reduces to about 2/3 cup, 2 to 3 minutes. Remove from heat and slowly whisk in butter, one piece at a time, until sauce forms. Serve steak drizzled with sauce. Garnish with green onions.
