Best 20 Leek Casserole Recipes

LEEK, POTATO, AND BACON CASSEROLE

Steps:

• Preheat the oven 325 degrees F.
• Butter an 8-by-8-inch square flameproof casserole dish. Halve the leeks lengthwise, and then cut them crosswise into half circles (There should be about 1 3/4 cups.). Put the cut leeks in the basket of a salad spinner, or a colander set in a bowl, and fill with water. Swish the leeks around to flush out any grit. Lift the basket from water--don't pour the water off or you will pour any grit right back over the leeks.
• Heat a medium skillet over medium heat and fry the bacon until crispy, about 5 minutes. Transfer the bacon to a paper towel-lined plate to cool, then crumble. Discard all but 1 tablespoon of the pan drippings, add the butter and leeks, and season with 1/2 teaspoon salt and some pepper. Cook until tender, about 10 minutes.
• Meanwhile, put the potatoes in a small saucepan with the garlic, thyme, and 1 1/2 teaspoons of salt and water, to cover. Bring to a boil over high heat, then drain. Discard the thyme and garlic and add potatoes to the leeks.
• In a medium bowl whisk together the eggs and half-and-half, then stir in the leek mixture, 1 cup of the cheese, the bacon, and nutmeg. Season with 1 teaspoon of salt and some pepper. Transfer the mixture to the prepared dish, cover with foil and bake until just set but still moist, about 55 minutes. Remove from the oven and set aside.
• Position a rack in the upper part of the oven and preheat the broiler. Scatter the remaining 1 cup cheese over the casserole and broil until the cheese browns, about 3 minutes. Set aside for 5 to 10 minutes before serving. Unmold or serve from baking dish.

SAUSAGE AND LEEK CASSEROLE

Steps:

• Heat oil in a heavy bottomed skillet on medium-high heat. Saute the leeks with a pinch of salt and pepper, red pepper flakes, and 1/8 teaspoon cayenne. When the leeks are translucent raise the heat to high and add the sausage and cook for 8 minutes or until browned. Remove from heat and allow the mixture to cool.
• In a separate bowl whisk the eggs together with the cream, milk, the remaining cayenne, a pinch of black pepper and salt.
• Cut the baguette into cubes and put in the bottom of a 9 by 9-inch glass casserole dish. Sprinkle the bread with the Cheddar cheese. Pour the sausage and leek mixture and egg mixture on top. Top with pepper jack cheese. Cover tightly and refrigerate overnight.
• Preheat oven to 375 degrees F.
• The next morning remove from refrigerator. Put in the middle of the oven and bake for 45 minutes or until a knife is removed cleanly from the middle. Remove from oven and allow the casserole to stand for 10 minutes before cutting and serving.

SWEET POTATO, APPLE AND LEEK CASSEROLE

Steps:

• Preheat the oven to 350 degrees F.
• In a large skillet, heat 1 tablespoon of the oil over medium heat. Add the leeks and 2 tablespoons water; season with salt and pepper. Cook, stirring occasionally, until tender but not browned, about 8 minutes. Add the thyme and then the cream and cook until the liquid thickens, about 2 minutes; set aside.
• In a 2-quart shallow baking dish, arrange the sweet potato in overlapping layers. Spread the leek mixture evenly over the potatoes. Arrange the apples in an overlapping layer on the leeks. Brush the apples with the remaining tablespoon of oil and sprinkle with the Parmesan. Cover tightly with aluminum foil and bake 40 minutes. Uncover and continue to bake until the Parmesan is golden brown and melted, about 20 minutes more. The tip of a paring knife should easily pierce the apples and potatoes. Let cool 10 minutes before serving.

CHEESE, LEEK, AND HERB SOUFFLE CASSEROLE

Steps:

• Heat 1 tablespoon butter in a large skillet over medium-high heat until pale gold, about 2 minutes. Add leeks and cook, stirring frequently, until softened and bright green, about 3 minutes. Season with salt and pepper; let cool. (Leeks can be made 1 day ahead and refrigerated.)
• Butter a 9-by-13-inch baking dish. Cut strips of parchment 4 inches wide and long enough to form a collar around inside of dish. Butter 1 side of parchment, and press unbuttered side against inside of dish. (Ends should overlap, and parchment should extend 2 inches above top of dish.) Place 1/2 cup Parmesan in dish, and coat sides well. Pour out and discard excess cheese.
• Melt 1 stick butter in a heavy saucepan over medium heat. Add flour, and cook, whisking constantly, until well combined and thoroughly heated. Remove pan from heat, and gradually add milk, whisking constantly until batter is very smooth before adding more milk. Add 1 teaspoon salt, and season with pepper. Return pan to medium heat, and whisk until souffle base is smooth, shiny, and thickened, about 12 minutes.
• Preheat oven to 400 degrees. Transfer souffle base to a bowl, and beat in egg yolks, 1 at a time, with a mixer on medium speed, increasing speed to high for 10 seconds after each addition to thoroughly incorporate. After last yolk is added, beat 20 seconds on high speed, then scrape down side of bowl. Add Gruyere, the remaining Parmesan, the leeks, and herbs, and beat until well combined.
• Beat egg whites with 1/2 teaspoon salt until stiff peaks form. Fold whites into souffle base, one third at a time, folding gently but thoroughly (a few streaks of whites are fine). Spoon souffle mixture into dish, and bake until puffed and golden, 35 to 40 minutes.

Separate chicken and vegetables into two bowls. Tear chicken into rough chunks when cool enough to handle.
• Melt butter in the same pan over medium heat. Sprinkle in flour, stirring frequently and breaking up any chunks. Continue to stir and cook until thickened and golden, making a roux. Gradually add the strained milk, stirring until you have a sauce. Stir in heavy cream and Dijon mustard, then add the chicken and vegetables. Remove from heat and let cool slightly, about 5 minutes.
• Pour chicken mixture into the prepared baking dish. Roll out the puff pastry and overlap the pieces to cover the casserole. Glaze the pastry with beaten egg and make several vents in the pastry using a sharp knife.

• Heat oil in a large skillet over medium heat and cook and stir beef, pork, curry, thyme, salt, and pepper until browned and crumbly, 10 to 15 minutes.
• Preheat the oven to 425 degrees F (220 degrees C). Grease a casserole dish with butter.
• Spread ground meat mixture in the casserole dish. Layer potatoes slices on top. Distribute tomatoes over potatoes and season with salt and pepper. Layer leeks on top and sprinkle with Cheddar cheese.
• Bake in the preheated oven until cheese is melted and lightly browned, about 30 minutes.

SAUSAGE, LEEK AND APPLE CASSEROLE

Steps:

• Cut the bacon into slices and brown it in a pan for a few minutes with the sausages. You can use cooking spray if you like but the bacon usually makes enough fat of it's own to help the sausages along.
• While the meat is browning, cut the mushrooms in half, cube the apple, slice the leek and cut the carrot into batons.
• When the meat is done, put it to one side in the crock pot / casserole dish along with the mushrooms and apple. Add the remaining veg (leek and carrot) to the pan to soften a little.
• After a couple of minutes, sprinkle the flour over the veg and mix through (the flour thickens the sauce, but if you prefer a more watery gravy then you can omit this step).
• Add the cider to the pan - it will bubble up to begin with but don't worry about it. Turn up the heat and cook for a couple of minutes to burn the alcohol off (I sniff-test it and cook until it stops smelling boozy).
• Transfer all the ingredients in the pan to the crock pot / casserole dish (cider and all).
• Now this is where you have to use your judgement a bit! I find 300ml water is usually about right to top up my crock pot, but you may find you need a bit more/less depending on the exact amount of ingredients you have used (ie. size of sausages, carrot, etc.). So as not to waste any of the stock cube, I crumble it into the crock pot without dissolving it in water first and then add as much water as is needed to JUST cover all the ingredients.
• CROCKPOT: Cook on Low for 8-9hrs or Medium for around 5hrs.
• OVEN: I've never actually made this in the oven but have no doubt it would work just as well. I would imagine that, if you cover the casserole dish and cook it at around 150 degrees it should be done in a couple of hours.
