Method

  1. Heat 1 tbsp olive oil in a large frying pan over a medium heat. Add the onions along with a pinch of salt and cook for 20 mins until nearly fully softened and caramelised, stirring occasionally. Add the butter and cook for a further 5 mins until deeply golden, stirring frequently.
  2. Preheat the oven to gas 6, 200°C, fan 180°C. Meanwhile, bring a large pan of slightly salted water to the boil and add the gnocchi. Cook for 2-3 mins until the gnocchi rise to the surface, then drain and set aside.
  3. Add the garlic and thyme to the onions and cook for 1 min, then add the stock. Bring to a simmer and simmer for 3 mins, until the stock has slightly thickened and reduced.
  4. Stir in the balsamic vinegar, if using, and season with pepper, then stir in the gnocchi. Tip the mixture into a 20cm square tin. Top with the mozzarella slices. Combine the breadcrumbs with the remaining olive oil and sprinkle over the top. Transfer the dish to the oven and bake for 20-25 mins until golden.
  5. Meanwhile, cook the peas in a small saucepan of slightly salted boiling water for 3 mins, then drain. Serve the gnocchi immediately with the peas on the side.
