Flank Steak with Charred Scallion and Lime Butter

8 scallions

¼ cup toasted sesame oil, divided

1 to 1½ lbs. flank steak (about 1-in. thick), trimmed

1¼ tsp. kosher salt, divided

¾ tsp. black pepper, divided

½ cup (4 oz.) unsalted butter, softened

2 tsp. finely grated lime zest plus 1 tsp. fresh juice (from 1 [2-oz.] lime)

1 tsp. minced garlic

¼ tsp. crushed red pepper

1. Trim 6 of the scallions; halve lengthwise. Thinly slice remaining 2 scallions, and set aside.

2. Heat 2 tablespoons of the oil in a large cast-iron skillet over high. Add scallion halves, and cook, stirring often, until charred, about 4 minutes. Transfer scallions to a plate. Reduce heat to medium high.

3. Add remaining 2 tablespoons oil to skillet. Season both sides of steak with 1 teaspoon of the salt and ½ teaspoon of the pepper. Carefully add steak to hot oil in skillet. Cook, turning once, until a thermometer inserted into thickest portion of meat registers 125° to 130° for medium-rare, 8 to 13 minutes, or until desired degree of doneness. Transfer steak to a cutting board, and let rest 10 minutes.

4. Finely chop charred scallions. Place in a medium bowl, and stir in softened butter, lime zest and juice, garlic, red pepper and remaining ¼ teaspoon each salt and pepper

5. Slice steak diagonally against the grain; top with scallion-butter mixture and reserved sliced scallions. Serve immediately.
