Grilled halibut and leeks with mustard vinaigrette recipe


Leeks are most often used as a flavoring for the main ingredient in a dish, but here they get equal billing. Related to both onion and garlic, they have flavor qualities of each but in a milder form. Grilled and dressed with a mustard-balsamic vinaigrette, they make a lovely side dish. For a little extra green, serve with mâche (also called lamb’s lettuce) or baby spinach if you like.

  • Yield: 4 Servings
  • Preparation Time: 20 Minutes


  • 1¼ pounds fresh or frozen halibut steaks, cut 1 inch thick
  • 2 tablespoons white balsamic vinegar
  • 2 tablespoons coarse-grain mustard
  • 1 tablespoon water
  • 4 teaspoons olive oil
  • 1 clove garlic, minced
  • 4 small leeks
  • 3 cloves garlic, minced
  • ¼ teaspoon salt
  • ¼ teaspoon ground black pepper
  • 1 to 2 cups mâche or baby spinach (optional)
  • Fresh chives (optional)
How to Make It
  1. Thaw fish, if frozen. Rinse fish; pat dry with paper towels. Cut into 4 serving-size pieces. Chill fish until needed. In a small bowl whisk together vinegar, mustard, the water, 2 teaspoons of the olive oil, and the 1 clove garlic. Set aside.
  2. Trim roots and cut off green tops of leeks; remove 1 or 2 outer white layers. Wash well (if necessary, cut a 1-inch slit from bottom end to help separate layers for easier washing). Drain. In a medium saucepan combine leeks and a small amount of water. Bring to boiling; reduce heat. Cover and simmer for 3 minutes. Drain. Pat dry. Brush with 1 teaspoon of the remaining olive oil.
  3. In a small bowl stir together the remaining 1 teaspoon olive oil, the 3 cloves garlic, the salt, and pepper. Spread evenly over fish; rub in with your fingers.
  4. For a charcoal or gas grill, place fish and leeks on the greased rack of an covered grill directly over medium heat. Grill for 8 to 12 minutes or just until fish flakes when tested with a fork, gently turning fish and leeks once. Cut leeks into ½-inch pieces. Divide fish and leeks among 4 shallow bowls. Drizzle with vinegar mixture. If desired, serve with greens and sprinkle with chives.
