Leek Prawn Gratin Recipes

SEAFOOD GRATIN

Steps:

• Preheat the oven to 375 degrees F. Place 4 individual gratin dishes on sheet pans. (If recipe is doubled serve it in a 14 by 9 1/4-inch oval gratin dish.)
• Combine the stock, cream, 1/2 cup of the wine, the tomato puree, and saffron in a medium saucepan. Bring to a boil, lower the heat, and add the shrimp. After 3 minutes, use a slotted spoon to remove the shrimp to a bowl. Add the halibut to the stock for 3 minutes, until just cooked through, and remove to the same bowl. Add the cooked lobster to the bowl.
• Continue to cook the sauce until reduced by half, about 12 minutes. Mash 1 tablespoon of the butter together with the flour. Whisk the butter mixture into the sauce along with 1 teaspoon salt and 1/2 teaspoon pepper. Simmer, stirring constantly, until thickened, about 5 minutes. Set aside.
• Melt 3 tablespoons of the butter in a medium saute pan. Add the leeks and carrots and cook over medium heat for 5 minutes, until softened. Add the remaining 3 tablespoons of wine, 1/2 teaspoon salt, and 1/4 teaspoon pepper and cook for 5 to 10 minutes, until tender. Set aside.
• Combine the panko, Parmesan, parsley, tarragon, and garlic. Melt the remaining 3 tablespoons of butter and mix it into the crumbs until they're moistened.
• Divide the seafood among the 4 gratin dishes. Strew the vegetables on top of each dish. Pour the sauce equally over the seafood and vegetables and spoon the crumbs evenly on top. Bake for 20 minutes, until the top is browned and the sauce is bubbly. Serve hot.

CREAMY POTATO AND LEEK GRATIN

Steps:

• Preheat oven to 400°F with rack in middle. Generously butter a 3-qt shallow baking dish. Cut a round of parchment paper to fit just inside a 12-inch heavy skillet, then set parchment aside.
• Halve leeks lengthwise, then cut crosswise into 1 1/2-inch pieces (you should have about 8 cups). Wash leeks.
• Cook leeks in butter with 1/2 tsp salt and 1/4 tsp pepper, covered with parchment round, in skillet over medium heat, stirring occasionally, until tender, 10 to 12 minutes.
• Meanwhile, peel potatoes and slice crosswise 1/16 inch thick with slicer. Transfer to a large heavy pot with cream, milk, thyme, 1 tsp salt, and 1/2 tsp pepper and bring to a boil over medium heat, stirring occasionally (liquid will thicken). Stir in leeks, then transfer to baking dish.
• Bake, uncovered, until potatoes are tender, 45 minutes to 1 hour. Let stand 10 minutes before serving.
• Do Ahead
• Gratin can be baked 2 days ahead and chilled. Let stand at room temperature 30 minutes, then reheat, covered, in a 350°F oven until hot, about 30 minutes.

CHEESY SEAFOOD GRATIN

Steps:

• Heat oven to 200C/180C fan/gas 6 and heat the oil in a large frying pan. Add the leeks and some seasoning, and cook for 10 mins until really soft. Stir in half the parsley and spoon into 2 gratin dishes.
• Divide the fish between the 2 dishes, mix the mustard into the cheese sauce and spoon over the top of the fish. Place on a baking tray and cook for 15 mins - you can put the bread in the oven to warm through for the last few mins if it is a little stale. Remove the bread from the oven and turn the grill on to brown the tops of the gratin for 2 mins, then remove from the oven. Scatter the gratin with the remaining parsley and serve with chunks of bread to mop up.

LEEKS AU GRATIN

Steps:

• Preheat oven to 375°. Cut off the root end and the tough leaf ends, then cut leeks lengthwise in half; cut halves crosswise into 3-in. pieces. Place cream, salt, pepper and leeks in a large cast-iron or other ovenproof skillet; bring to a boil over medium-high heat. Reduce heat; simmer, covered, 5 minutes. Uncover; simmer 15 minutes. Remove from heat; sprinkle with cheese., Bake, uncovered, until top is golden and leeks are tender, 15-20 minutes. Let stand 5-10 minutes before serving.

QUICK, SPICY LEEK AND SHRIMP STIR-FRY

Steps:

• Trim the ends and dark green tops from the leeks and discard. Cut the leeks in half lengthwise, then crosswise into 1-inch pieces. Immerse them in a bowl of cold water, swish to remove any grit and lift them out into a colander. Clean the bowl, change the water and repeat until the water remains clear. You should have 6 cups leeks. Once they are all in the colander, toss them a bit with your fingers to separate the leaves.
• Heat a large skillet over high heat until hot. Add 1 tablespoon of the oil and swirl to coat the bottom of the pan. Add half the leeks and a generous pinch each salt and pepper. Spread the leeks into a single layer and cook, without stirring, until slightly charred, about 1 minute. Stir in a small pinch pepper flakes and continue cooking, without stirring, 1 minute. Toss and stir until the leeks just start to wilt, about 1 more minute. Transfer to a bowl. Repeat with 1 tablespoon of the oil, the remaining leeks, a generous pinch each salt and pepper and another small pinch pepper flakes, adding the leeks to the bowl when done.
• Heat the remaining tablespoon of oil in the skillet (let it get really hot). Add the shrimp, garlic and another pinch pepper flakes (or to taste). Season with salt and pepper, and cook, tossing, until the shrimp just starts to turn pink in spots, less than 1 minute. Add the leeks and toss to combine; the shrimp should now be pink. Serve immediately over rice if using.

SHRIMP AU GRATIN

Steps:

• Preheat the oven to 350 degrees F (175 degrees C).
• Heat oil and butter in a skillet over medium-high heat until butter melts. Reduce heat to medium, whisk in flour, and stir until a thick paste forms, about 5 minutes. Gradually whisk in milk and bring to a simmer. Cook and stir until the sauce is thick and smooth, 5 to 10 minutes. Season with nutmeg and salt.
• Place shrimp in a casserole dish and coat with 3 teaspoons Italian seasoning and salt to taste. Cover with sauce and sprinkle Cheddar cheese on top. Add shallot, remaining Italian seasoning, and parsley. Top with bread crumbs, followed by Parmesan cheese.
• Bake in the preheated oven until crisp, about 25 minutes.

LEEK GRATIN

Steps:

• Preheat oven to 375 degrees. Halve leeks lengthwise, leaving halves attached at root, and rinse well, shaking off water.
• In a large skillet, combine cream and leeks; season with salt and pepper. Bring to a boil over medium-high; reduce to a medium simmer, cover, and cook 5 minutes. Uncover and simmer until leeks are tender, 15 minutes. Transfer leeks and sauce to a shallow 2-quart baking dish.
• Sprinkle with cheese and bake until golden and bubbling, about 35 minutes. Let gratin rest 10 minutes before serving.

POTATO & LEEK GRATIN

Steps:

• Pour the stock, cream and milk into a small saucepan, add the garlic and bay leaf and bring to the boil. Remove from the heat, cover and let the flavours infuse while you get on with the rest of the dish.
• Preheat the oven to 180C/gas 4/fan 160C. Butter a 2 litre gratin dish well. Mix the potatoes, leeks and ham (if using) together in the dish, and spread out in an even layer. Pour over the stock mixture and tuck the bay leaf in the middle. Season and sprinkle with the cheese.
• Stand the dish on a baking tray to catch any spills. Loosely cover with foil and bake for 30 minutes. Test the potatoes with a knife - they should be just beginning to soften. Remove the foil and bake for another 35-45 minutes, spooning some of the stock mixture over every now and again until the potatoes are tender. Cool for 15 minutes before serving.

LEEKS AU GRATIN

Steps:

• Heat oven to 325°F. Grease bottom and side of shallow 2-quart casserole. Cut leeks into 1/2-inch pieces. In 3-quart saucepan, heat 2 inches water to boiling. Add leeks. Cover and cook over medium heat about 5 minutes or until crisp-tender; drain.
• In 2-quart saucepan, melt 2 tablespoons butter over low heat. Cook flour, salt and pepper over low heat, stirring constantly, until smooth and bubbly; remove from heat. Gradually stir in milk. Heat to boiling, stirring constantly. Boil and stir 1 minute. Stir in cheese until melted. Stir in leeks. Pour into casserole.
• In small bowl, mix bread crumbs and 2 teaspoons butter until crumbly. Sprinkle evenly over casserole.
• Bake uncovered about 25 minutes or until golden brown.

HADDOCK & LEEK AU GRATIN WITH SWEETCORN MASH

Steps:

• Heat oven to 200C/180 fan/gas 6. Boil the potatoes for 15-20 mins until tender, then drain. Reserve 3 tbsp corn and blitz the rest (with its juice) using a hand blender or a food processor until completely smooth, then mash into the potatoes. Cook the spinach following pack instructions - if you have a microwave, choose this method.
• Put the leeks in a pan with the 300ml milk and the butter. Cook gently, part-covered, for 8 mins until the leeks are tender. (Keep an eye on things as milk can easily boil over.) Mix the 3 tbsp milk with the flour and mustard, then stir into the leek mixture - keep stirring until thickened. Take off the heat and stir in three-quarters of the cheese.
• Squeeze as much liquid as you can from the spinach, then arrange on the base of 2 gratin dishes. Place a fish fillet on top of each, then spoon over the leek & cheese sauce. Top with the sweetcorn mash. Mix the remaining corn and cheese, and scatter on top. Place the dishes on a baking tray and cook for 25 mins until the fish flakes when tested and the top is golden.

SPRING GREENS AND LEEK GRATIN

Steps:

• Preheat oven to 350°F. Melt butter in an ovenproof 10" skillet (such as cast iron) over medium-low heat. Add leeks and ramp bulbs and cook, stirring often, until leeks are softened, about 10 minutes. (Try to keep the leeks from browning.)
• Add ramp greens, arugula, and spinach in big handfuls, cooking and wilting one batch before adding the next. (At first it will look like all those greens will never fit in the skillet, but keep at it-you'll see!) When all greens are wilted (this may take 15-20 minutes), add coriander, salt, and cayenne. Cook, stirring, until spices are incorporated, about 1 minute. Add lemon zest, cream, and 1/2 cup Parmesan. Continue to cook, stirring, until cream has slightly reduced, about 2 minutes longer. Remove from heat.
• Toss bread with oil in a large bowl to coat. Arrange bread on top of vegetables, taking care not to cover the greens completely (you want them to peek through here and there). Sprinkle remaining 2 Tbsp. Parmesan over.
• Transfer to oven and bake gratin until bread is golden brown and crisp, cheese is melted, and cream is bubbling, 35-45 minutes. Let cool slightly before serving.
