Ingredients for Za’atar fish and chips

  • 1 small red onion, finely chopped

  • 60 ml apple cider vinegar, divided

  • kosher salt (to taste)

  • 675 g small Yukon Gold potatoes, halved or quartered lengthwise

  • 90 ml extra-virgin olive oil, divided

  • 450 g skinless, boneless cod fillet, preferably in 1 piece

  • 15 g za’atar

  • 110 g pitted Castelvetrano olives

  • 15 g coarsely chopped mint

How to make Za’atar fish and chips

  1. Place the oven racks in the upper and lower thirds of the oven and preheat to 220°C (fan) / 230°C (conventional).

  2. In a small bowl, mix the onion, 2 tablespoons of vinegar, and a generous pinch of salt; let the mixture sit for at least 10 minutes and up to 1 hour. Drain off the vinegar and discard it.

  3. Meanwhile, toss the potatoes with 3 tablespoons of oil on a large rimmed baking tray; arrange them in a single layer. Roast on the top rack, undisturbed, for 20–25 minutes, or until browned and crisp underneath.

  4. Turn the potatoes over and reduce the oven temperature to 160°C (fan) / 170°C (conventional). Place the cod on a small rimmed baking tray and drizzle with 1 tablespoon of oil. Season with salt and sprinkle with za’atar.

  5. Slide the cod onto the bottom rack of the oven and roast for about 10 minutes, or until the fish flakes easily with a fork and the potatoes are browned all over.

  6. Stir the olives, mint, remaining 2 tablespoons of vinegar, and remaining 2 tablespoons of oil into the pickled onion.

  7. Serve the cod and potatoes topped with the olive mixture.
