Summer Tomato Bouillabaisse with Basil Rouille

This summer tomato bouillabaisse is a vibrant, lighter take on the classic French fisherman’s stew. By swapping a heavy stock for a base of sweet, burst cherry tomatoes and aromatic fennel, the dish captures the essence of coastal Mediterranean dining. The mixed shellfish, including clams and mussels, provides a high-protein punch, while the addition of clam juice and white wine creates a deeply savoury broth that perfectly balances the acidity of the seasonal fruit.

To elevate the meal, the stew is served alongside a zesty basil rouille. This punchy condiment, enriched with anchovies and garlic, is spread onto crusty bread to be dipped into the fragrant liquid. It is an impressive yet straightforward seafood dish that is ideal for a relaxed weekend lunch or an elegant alfresco dinner party with friends.
