  7. 1 large onion, finely chopped
  8. 1 celery rib, cut into 1/2-inch pieces
  9. 1 fennel bulb—halved, cored and cut into 1/2-inch pieces
  10. 1/2 tablespoon coarsely ground pepper
  11. 1/2 tablespoon ground fennel seeds
  12. 1/2 tablespoon ground cumin
  13. 1/2 teaspoon sweet paprika
  14. 1/8 teaspoon crumbled saffron threads
  15. 3 tablespoons tomato paste
  16. 1 cup dry white wine
  17. 2 quarts fish stock or 1 quart clam juice diluted with 1 quart water
  18. 12 thyme sprigs, tied in a bundle with kitchen string
  19. Freshly ground pepper
  20. 1 1/2 pounds monkfish or other meaty white fish, filmy outer skin removed, fish cut into 1-inch pieces
  21. 1 pound skinless cod fillet, cut into 1-inch pieces
  22. 1 pound tuna, cut into 1-inch pieces
  23. 1 small baguette, thinly sliced
  24. Pinch of dried oregano
  25. 1/2 cup freshly grated Parmesan cheese
  1. In a medium saucepan of boiling salted water, cook the potato cubes until tender, about 15 minutes. Drain, reserving 2 tablespoons of the potato cooking water. Transfer the potato cubes to a medium bowl. Add the reserved potato water and the minced garlic and mash until smooth. Whisk in 1 cup of the olive oil in a thin stream until the rouille is creamy. Season the rouille with salt and cayenne.
  2. Preheat the oven to 350°. In a large soup pot, heat the remaining 1/2 cup of olive oil until shimmering. Add the leeks, onion, celery, fennel bulb and 6 of the halved garlic cloves and cook over high heat, stirring frequently, until the vegetables are softened and lightly browned, about 9 minutes. Add the coarsely ground pepper, ground fennel, cumin, paprika, crumbled saffron and tomato paste and cook until fragrant, about 1 minute. Add the wine to the soup pot and cook until it is nearly evaporated, about 8 minutes.
  3. Add the fish stock and thyme bundle to the pot and bring the soup to a boil. Season with salt and pepper and simmer for 10 minutes. Add the monkfish, cod and tuna and simmer the soup until the fish is cooked through, about 8 minutes. Discard the thyme bundle.
  4. Meanwhile, arrange the baguette slices on a baking sheet. Brush the slices all over with olive oil and sprinkle on one side with the oregano. Toast the baguette slices for about 5 minutes, or until the toasts are crisp and lightly golden. Rub the toasts with the 2 remaining halved garlic cloves.
  5. Ladle the fish soup into deep bowls and stir some of the rouille into each. Serve the garlicky croutons, the Parmesan cheese and the remaining rouille on the side.

Suggested Pairing

A big, bold, crisp white from France will stand up to the pungent garlic and acidic tomato flavors in this hearty fish soup. Or, try a Pinot Blanc from California.
