Best 5 Canadian Cod Au Gratin Recipes

TRADITIONAL NEWFOUNDLAND COD AU GRATIN

Steps:

• Preheat oven to 375 degrees Fahrenheit.
• Place cod in a casserole dish (about 8-inch x 11-inch or something similar) and sprinkle with 1/4 teaspoon of salt. Set aside until you make the sauce. See "Notes" below if using cod fillets that have been previously frozen.
• In a small saucepan on the stovetop, heat milk over low heat just to warm through (the milk will be used shortly for the sauce).
• Meanwhile, in another saucepan on the stovetop, heat 1 tablespoon of olive oil over medium-low heat. Add onion and cook, stirring often, until softened, about 5 minutes.
• To onion, add butter; melt. Add flour and stir to form a paste. Cook, stirring often, for about 3 to 5 minutes. Slowly add the warmed milk to this (1/2 cup at a time), whisking after each addition until thickened, about 3 to 4 minutes or so. Sauce mixture should coat the back of a spoon. Mixture will be thick.
• To sauce mixture, add remaining 1 teaspoon of salt, black pepper, lemon zest and 1.5 teaspoons of dill (you can use less, if you prefer). Stir to combine. Pour sauce mixture over cod, coating all fish. Stir to ensure mixture is incorporated well.
• Sprinkle cheddar cheese and croissant crumbs (or regular bread crumbs) on top of sauced fish mixture. Bake in preheated oven for 40 minutes until golden brown and bubbly.
• Once done, sprinkle remaining 1/4 teaspoon of dried dill over top. Let cool for about 20 to 30 minutes before serving (don't skip this; it allows things to settle). Serve with lemon wedges (if desired). Enjoy!

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.
