Hanger Steak with Charred Spring onion Sauce

This sophisticated hanger steak with charred spring onion sauce is a wonderful choice for a high-protein, diabetes-friendly dinner. Hanger steak, often prized by butchers for its deep, savoury flavour, pairs beautifully with the textured sauce. The combination of toasted walnuts, tangy capers, and smoky charred spring onions creates a vibrant topping that elevates the meat without the need for heavy, calorie-dense sauces. Use a good quality extra-virgin olive oil to bring all the Mediterranean-inspired flavours together.

Quick to prepare and naturally low in carbohydrates, this dish is perfect for a nutritious mid-week meal or a relaxed weekend supper. The inclusion of heart-healthy fats from the walnuts and olive oil ensures a satisfying finish, while the vinegar and mustard provide a sharp brightness. Serve the sliced steak with a side of steamed greens or a crisp seasonal salad for a light yet comforting meal that supports a balanced lifestyle.

Ingredients for Hanger Steak with Charred Spring onion Sauce

  • 80g crushed or coarsely chopped walnuts

  • 1 small garlic clove

  • 140ml extra-virgin olive oil, divided

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

  • Kosher salt, freshly ground pepper

  • 3/4 teaspoons Aleppo-style pepper, plus more for serving

  • 12 spring onions

  • 25ml sherry vinegar or red wine vinegar

  • 1 tablespoon chopped cornichons

  • 1 tablespoon chopped drained capers

  • 1 tablespoon whole grain mustard

  • 3/4 teaspoons chopped thyme

  • Pinch of sugar

  • Flaky sea salt

Preheat oven to 177°C. 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 90ml 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 tablespoons 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 spring onions and 1 tablespoon 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 spring onion sauce and more Aleppo-style pepper.
