LEEK AND POTATO CASSEROLE

Steps:

• Preheat the oven to 350 degrees F. Butter an oval baking dish. Drain the leeks and rinse.
• In a large skillet, melt the butter over medium heat. Add the leeks and thyme, season with salt and pepper and cook, stirring, until the leeks are softened and golden, 5 to 7 minutes.
• Peel and slice the potatoes into very thin rounds. Sprinkle with salt and pepper. Layer half of the potatoes in the buttered dish, then layer half of the cooked leeks over the potatoes. Repeat the layers.
• Return the skillet to medium heat and add the cream cheese, cream, chicken stock and garlic. Stir together, scraping up any brown bits from the bottom of the skillet. Sprinkle with the paprika and some salt and pepper. Bring to a boil, lower to a simmer and simmer for about 5 minutes so the cheese melts. Pour the cream mixture over the leeks and potatoes and top with the grated cheese.
• Cover with foil and transfer to the oven. Bake for 40 minutes, then remove the foil and continue baking until the cheese is bubbly and golden, 15 to 20 minutes more. Allow to cool slightly before serving.

CHICKEN, LEEK, AND MUSHROOM CASSEROLE

Steps:

• Preheat oven to 350 degrees. Season chicken on both sides with salt and pepper. Heat 2 tablespoons oil in a medium saute pan over medium-high heat. Add chicken, and cook until golden brown on 1 side, 3 to 4 minutes. Flip, reduce heat to medium, and cook until cooked through, about 10 minutes more. Transfer chicken to a plate, and return pan, with drippings, to medium heat.
• Heat remaining 3 tablespoons oil in pan. Add leek, celery, mushrooms, and a pinch of salt. Cook, stirring occasionally, until vegetables are golden brown and tender, 8 to 10 minutes. (Reduce heat if vegetables brown too quickly.) Stir in flour, and cook, stirring often, for 2 minutes. Add sherry, stock, milk, and bay leaf, and cook, scraping up browned bits from bottom, until thickened, about 5 minutes. Season with salt and pepper. Discard bay leaf.
• Arrange bread on bottom of a 2-quart oval baking dish, overlapping slices slightly. Spoon half of the vegetables and sauce over bread. Slice chicken crosswise, 1/2 inch thick, and arrange on bread. Top with any accumulated juices from chicken. Spread remaining vegetables and sauce over chicken, sprinkle with parsley and Parmesan, and bake until golden brown and bubbling, 25 to 30 minutes. Let stand for 15 minutes before serving.

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.

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.

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.

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.
