Best Salt Cod And Leek Gratin Recipes

POACHED COD WITH POTATOES AND LEEKS

Steps:

• Place potatoes in a medium pot and add cold water to cover by 1"; season with salt and bring to a boil. Reduce heat and simmer until fork-tender, 15-20 minutes. Drain, reserving 1/4 cup cooking liquid. Return potatoes to pot; add 2 Tbsp. cooking liquid and 2 Tbsp. oil and lightly mash. Season with salt. Keep potatoes warm over low heat until ready to serve.
• Combine leeks, thyme, garlic, and milk in a medium wide saucepan. Season generously with salt and bring to a simmer over medium heat. Cook until leeks are just beginning to soften, 6-8 minutes. Gently slide cod into infused milk and poach until flesh is cooked through and beginning to flake, 7-9 minutes (adjust heat as needed to maintain a low simmer; thicker pieces of fish will take longer to cook).
• Divide warm potatoes, leeks, and cod among shallow bowls. Spoon some poaching liquid over each. Drizzle with oil; season with pepper.

CREAMY COD AND POTATO GRATIN

Steps:

• Place potatoes in a large pot of well-salted water and bring to a boil over high heat. Reduce heat and simmer gently until tender, about 20 minutes.
• While potatoes simmer, trim, bone, and cut the cod fillets across into 2-inch pieces.
• Drain potatoes well and return to the pot. Add a pinch of cayenne, salt, and 4 tablespoons butter. Mash until smooth.
• Preheat the oven to 450 degrees F (230 degrees C). Grease 2 individual-sized casserole or baking dishes with 1 tablespoon butter. Place both dishes on a baking sheet.
• Transfer about 2/3 cup of the mashed potatoes into each of the prepared dishes. Smooth out evenly and make a shallow depression with a spoon down the middle. Set aside.
• Heat remaining 2 tablespoons butter in a deep 10-inch skillet over medium-high heat. Cook the shallots in the hot butter with a pinch of salt until they just start to turn golden, 3 to 4 minutes. Add cream, lemon zest, and a pinch of cayenne, and bring to a simmer. Add cod and wait for the sauce to come back to a simmer. Cook for 1 minute, while basting with the sauce; turn and cook for 1 minute more.
• Pour in lemon juice and turn off the heat; stir for about 30 seconds.
• Divide the pieces of cod over the potato. Add enough sauce to just cover the fish and return the pan to the stove.
• Bring sauce to a boil over medium-high heat and cook until the sauce reduces and thickens, 1 to 2 minutes. Turn off the heat and stir in tarragon.
• Spoon the thickened sauce over the cod. Add a light dusting of Parmigiano-Reggiano cheese.
• Bake in the center of the preheated oven until cod is cooked through and the sauce is browned and bubbling, 10 to 15 minutes. Let rest for 5 minutes before serving.

COD, LEEK & POTATO GRATIN

Steps:

• Preheat the oven to 375°.
• Butter a 13-inch oval gratin pan or 4 deep, individual-sized baking dishes.
• Cut the potatoes crosswise into thin, uniform slices.
• Cut the leeks crosswise into slices about twice as thick as the potatoes.
• Season the fish lightly with salt and pepper.
• Arrange half of the potato slices in the prepared dish, overlapping them to cover the bottom.
• Season lightly with salt and pepper.
• Scatter half of the leeks over the potatoes, then arrange the fish slices over the leeks in a single layer, overlapping the slices as necessary.
• Top with the remaining leeks, then with the remaining potatoes.
• Season with salt and pepper.
• Pour the cream evenly over the layers; bake for 40 minutes.
• Remove from the oven and spoon some of the cooking liquid over the top of the gratin to moisten the potatoes and help them brown.
• Continue to bake until the top layer of potatoes is tender when pierced with a sharp knife, about 20 minutes.
• Let stand for 10-15 minutes and serve.
