Ingredients

1/2 cup crushed or coarsely chopped walnuts

1 small garlic clove

9 Tbsp. extra-virgin olive oil, divided

1 (1 1/2-lb.) hanger steak, cut into 4 pieces, center membrane removed

Kosher salt, freshly ground pepper

3/4 tsp. Aleppo-style pepper, plus more for serving

12 scallions

5 tsp. sherry vinegar or red wine vinegar

1 Tbsp. chopped cornichons

1 Tbsp. chopped drained capers

1 Tbsp. whole grain mustard

3/4 tsp. chopped thyme

Pinch of sugar

Flaky sea salt

Method

Preheat oven to 350°F. Toast walnuts on a rimmed baking sheet, tossing once, until golden brown, 8–10 minutes. Transfer to a medium bowl. Finely grate garlic over warm walnuts and toss with 6 Tbsp. oil.

Heat a large cast-iron skillet over medium-high. Season steaks with kosher salt and black pepper; sprinkle all over with Aleppo-style pepper. Rub with 2 Tbsp. oil and cook, turning occasionally, until deeply browned and an instant-read thermometer inserted into the thickest part registers 130° for medium-rare, 10–12 minutes. Transfer steaks to a cutting board.

Wipe out skillet and reduce heat to medium. Place scallions and 1 Tbsp. oil in skillet, season with kosher salt, and cook, turning occasionally, until softened and deeply charred, about 4 minutes. Transfer to cutting board; trim and cut into 1" pieces. Add to bowl with walnut mixture along with vinegar, cornichons, capers, mustard, thyme, and sugar and toss to combine; season with kosher salt and black pepper.

Slice steak against the grain and sprinkle with sea salt. Serve with scallion sauce and more Aleppo-style pepper.
