WHY THIS RECIPE WORKS Cooking mild, sweet, meaty halibut fillets on a generous pile of sliced leeks in butter and white wine creates an irresistible fusion of flavors. Finishing this fast and easy-to-prepare but elegant dish with a quick lemony mustard pan sauce sealed the deal. The gentle, moist heat of braising resulted in perfectly silky textured fish fillets. Halibut has a delicate flavor and firm texture that we prefer in this recipe, but another similar firm-fleshed white fish such as striped bass or sea bass that is between ¾ and 1 inch thick can be substituted. To ensure that your fish cooks evenly, purchase fillets that are similarly shaped and uniformly thick.
INGREDIENTS:
- 4 (6-to 8-ounce) skinless halibut fillets, ¾ to 1 inch thick
- Salt and pepper
- 6 tablespoons unsalted butter
- 1 pound leeks, white and light green parts only, halved lengthwise, sliced thin, and washed thoroughly
- 1 teaspoon Dijon mustard
- ¾ cup dry white wine
- 1 teaspoon lemon juice, plus lemon wedges for serving
- 1 tablespoon minced fresh parsley
INSTRUCTIONS:
- Sprinkle fish with ½ teaspoon salt.
- Melt butter in 12-inch skillet over low heat.
- Place fish in skillet, skinned side up, increase heat to medium, and cook, shaking pan occasionally, until butter begins to brown (fish should not brown), 3 to 4 minutes.
- Using spatula, carefully transfer fish to large plate, raw side down.
- Add leeks, mustard, and ½ teaspoon salt to skillet and cook, stirring frequently, until leeks begin to soften, 2 to 4 minutes.
- Add wine and bring to gentle simmer.
- Place fish, raw side down, on top of leeks.
- Cover skillet and cook, adjusting heat to maintain gentle simmer, until fish registers 135 to 140 degrees, 10 to 14 minutes.
- Remove skillet from heat and, using 2 spatulas, transfer fish and leeks to serving platter or individual plates.
- Tent with aluminum foil.
- Return skillet to high heat and simmer briskly until sauce is thickened, 2 to 3 minutes.
- Off heat, stir in lemon juice and season with salt and pepper to taste.
- Spoon sauce over fish and sprinkle with parsley.
- Serve immediately with lemon wedges.
