Starter
French Onion Gratin
the slow-caramelised version
with gruyère croutons
Roasting concentrates everything that makes a tomato great — sweetness, acidity, umami. Two hours in the oven transforms even average tomatoes into something extraordinary. A generous scatter of crispy Gruyère-topped croutons turns this into a full meal.
Serves 6
Preheat oven to 160°C (140°C fan). Arrange the tomatoes cut-side up in a large roasting tin with the onions and garlic. Drizzle with olive oil, sprinkle with sugar, season well. Roast for 1½–2 hours until collapsed, caramelised and very fragrant.
Squeeze the softened garlic cloves out of their skins. Blend everything with the basil and stock until smooth. Pass through a sieve for a silkier texture, or leave rustic.
For the croutons, tear the sourdough into chunks, toss with a little olive oil, and scatter with Gruyère. Grill until golden and bubbling.
Reheat the soup gently, adjust seasoning, and ladle into bowls. Top with the Gruyère croutons and a drizzle of olive oil.
