Best Baked Fish With Onions Recipes

MEDITERRANEAN BAKED WHITE FISH

Steps:

• Heat the oven to 425 degrees F.
• Pat the fish dry and season with salt and pepper on both sides. Brush a 9 ½ x 13-inch baking dish with a little extra virgin olive oil and put the fish in it. Squeeze ½ lemon juice all over the top of the fish.
• In a medium mixing bowl, combine the tomatoes, olives, onions, garlic and spices. Add a very small pinch of salt and ground pepper. Add a generous drizzle (about 3 tablespoons extra virgin olive oil) toss to combine.
• Pour the tomato and olive mixture over the fish.
• Bake in the heated oven for 15 to 20 minutes (this will depend on the thickness of your fish).
• Remove from the heat and serve.

BAKED COD WITH POTATOES AND ONIONS

Steps:

• Preheat the oven to 350 degrees F (175 degrees C). Butter a large, rectangular baking dish.
• Place the fish in the prepared dish. Arrange potato and onion slices around and on top. Pour enough milk over top to just barely cover. Season with a generous amount of salt and pepper. Dot butter over top.
• Bake, uncovered, in the preheated oven until fish flakes easily with a fork and potatoes are tender, about 45 minutes, checking frequently and adding more milk if necessary. Serve in large bowls.

BAKED COD WITH TOMATOES AND ONIONS

Steps:

• Preheat the oven to 400 degrees F.
• Place the fish in a large colander and rinse under cold running water. Place in a large non-reactive baking dish, and make 5 horizontal 3-inch slits on each side. Season the fish on both sides with 2 tablespoons olive oil, 3 teaspoons kosher salt, and 1/2 teaspoon black pepper.
• In a mixing bowl, toss together the sliced tomatoes, onions, garlic, remaining 1 tablespoon olive oil, 1 teaspoon kosher salt, and 1/2 teaspoon black pepper. Set aside until needed.
• Place the fish, skin side down, in a roasting pan. Thickly coat the top side of the fish with the olive spread. Layer the tomatoes and cilantro flat on top of the tapenade like scales, then top with the onions and garlic. Place the fish in the oven and bake until the juices run clear and the onions are beginning to crisp and slightly blacken along the edges, about 20 minutes.
• Remove the fish from the oven and let rest for 15 minutes. Place the fish on a platter and serve, garnished with cilantro sprigs.
• In the bowl of a food processor, combine all the ingredients and puree. Transfer to a bowl. Cover and set aside until needed, or refrigerate for up to 3 days in an airtight container.

GREEK BAKED FISH WITH TOMATOES AND ONIONS

Steps:

• Pat the fish dry and season to taste with salt and pepper. Oil one or two baking dishes large enough to accommodate the fish in one layer. Lay the fish in the dish and pour on the lemon juice. Refrigerate for 30 to 60 minutes while you prepare the remaining ingredients.
• Preheat the oven to 375 degrees. Heat the oil over medium heat in a large, heavy skillet and add the onions. Cook, stirring often, until they have softened and begun to color slightly, 8 to 10 minutes. Add a generous pinch of salt and the garlic and cook, stirring, until the garlic is fragrant, 30 seconds to a minute. Stir in the tomatoes, sugar, paprika, cinnamon, dissolved tomato paste, wine, half the parsley and more salt and pepper to taste and bring to a simmer. Simmer uncovered, stirring often, until the sauce has cooked down a bit and is very fragrant, about 15 minutes. Remove from the heat and pour over the fish. Sprinkle on the remaining parsley.
• Place in the oven and bake until the fish is opaque and pulls apart easily with a fork, about 30 minutes. Baste the fish every 10 minutes if it is not submerged in the sauce. Serve hot or warm, with rice, bulgur, or potatoes.

MOROCCAN BAKED FISH WITH ONIONS

Steps:

• Season fish fillets lightly with salt and pepper and set aside. Wash cilantro and pat dry. Reserve a few cilantro sprigs for garnish, then roughly chop leaves and tender stems and put in a medium bowl. Add 1/2 teaspoon salt, the garlic, the chile, 1/2 teaspoon ground cumin, 1/2 teaspoon ground coriander, the paprika, 1/2 cup olive oil and the lime juice. Stir mixture together.
• Pour cilantro sauce over fish fillets, reserving 4 tablespoons of the sauce for serving. Coat both sides of fish with the mixture. Cover and leave at room temperature for 1 hour, or refrigerate for up to several hours.
• Meanwhile, put butter and remaining 2 tablespoons olive oil in a wide skillet over high heat. Add sliced onions and season generously with salt and pepper. Add remaining ground cumin and ground coriander, 1/2 teaspoon whole coriander seeds, the turmeric and the cayenne. Stir to coat. When onions begin to soften, turn heat to medium. Continue cooking, stirring occasionally, for about 15 minutes, until onions are soft and begin to brown. Stir in preserved lemon and olives. Cool to room temperature. (The onions may be cooked in advance.)
• Heat oven to 400 degrees. Spread onions in a low baking dish. Arrange marinated fish fillets over onions in a single layer. Bake on top rack until fish is just done, 10 to 15 minutes. To serve, smear a little reserved cilantro sauce over each fillet, and give each guest a large spoonful of the onions. Garnish with cilantro sprigs.
