  1. Put a baking tray in the oven and preheat it to gas 6, 200°C, fan 180°C. Put the onions in a large baking dish and toss with 1 tbsp oil; season. Bake for 10 mins. Meanwhile, cut 4 thin slices from the lemon and set aside.
  2. Stir the spinach, tomatoes, garlic, rosemary and another 1 tsp oil into the baking dish with the onions. Top with the fish, drizzle each fillet with ½ tsp oil, season and top with the lemon slices. Cover the dish with foil.
  3. Remove the hot baking tray from the oven. Put the potatoes on the baking tray and toss with 1 tbsp oil; arrange in an even layer. Bake the fish and potatoes for 25-30 mins, turning the potatoes halfway through, until the fish is flaking and cooked through and the potatoes are browned and crisp. Squeeze the remaining lemon over the fish and scatter with the parsley to serve.
