MUSHROOM POTATO GRATIN -COURTESY MICHELLE BERNSTEIN-MARTINEZ-

Steps:

• Preheat the oven to 400 degrees with the rack in the upper half of the oven.
• Thinly slice the potatoes about 1/8 inch on a mandolin, food processor, or the old fashioned way, a sharp knife .
• Melt the butter in a large sauté pan over high heat and add the shallots and sliced mushrooms and cook for about 6 to 8 minutes.
• Add the re-hydrated porcinis to the pan (if using) and sauté until the liquid from the mushrooms has evaporated.
• Season the mushrooms with salt and pepper.
• Add the chicken stock, 1 1/4 cup of the cream, and chopped herbs, heat through, do not boil.
• Use an oiled 3-quart baking dish.
• Begin with a layer of about 1/3 of the potatoes, 1/2 of the mushrooms and cream and a little of each cheese, 1/3 of the potatoes, the remaining 1/2 of the mushrooms with cream, then the final layer of potatoes.
• Pour the remaining 1/2 cup cream over the potato layers and top with the remainder of the cheeses.
• Cover with foil.
• Bake until the potatoes are tender and the cream is almost completely set and thickened, about 1 ½ hours.
• Uncover and top with breadcrumbs and cook until golden, about 15 minutes.

POTATOES AU GRATIN

Steps:

• Preheat the oven to 350 degrees F.
• Butter a 1 1/2 quart baking dish with about 1 tablespoon of the softened butter.
• Arrange a layer of potatoes in the baking dish, and sprinkle some of the cheeses over them. Continue layering potatoes and cheeses until you've used them all, ending with a layer of potatoes.
• In a small bowl, whisk the cream with the salt and pepper; pour this over the potatoes. Dot the remaining butter over the top and sprinkle with the paprika. Bake for 1 to 1 1/4 hours, or until the potatoes are tender and golden brown on top. Let stand for 5 minutes before serving.

POTATO/PORTOBELLO GRATIN

Steps:

• Heat oven to 400 degrees and butter a 9 by 13-inch baking dish and set aside.
• Using a mandolin, V-slicer or the slicing attachment on a food processor, slice the potatoes approximately 1/8-inch thick. (If you don't want to slice all the potatoes at once, slice them one at a time and build the gratin as you go.) Create the first layer by laying the slices in overlapping rows. Once the first layer is down, season lightly with salt and pepper, then scatter with mushroom slices and a couple tablespoons of the cheese. (Don't over-do it on these layers, if you create a barrier between the adjoining potato layers, the gratin won't set.) Continue building layers until you're out of potatoes or out of room to build, but be sure to save 1/2 cup of the cheese for the top.
• Pour 2/3 cup of the half and half over the gratin then spread both hands over the surface and push down to work the air out from the layers. Add remaining liquid only if half and half does not come to the surface when you push down. Sprinkle the gratin with cheese, cover loosely with foil and place in middle of oven for 1 hour. Check for doneness by inserting the point of a paring knife straight into the gratin. If it goes through smoothly, remove the foil, return to oven, and turn on the broiler just long enough to turn the top golden-brown. Remove, and allow to sit at room temperature for 15 to 20 minutes before serving.

POTATO AND MUSHROOM GRATIN

Steps:

• In a saucepan, combine milk, cream, garlic, 3 thyme sprigs and 1 bay leaf over low-medium heat. Heat to just under a boil. Remove from heat, cover, and let steep while preparing the rest of the dish.
• Coat a skillet with olive oil and place over medium heat. Add remaining thyme and bay leaf. Saute the mushrooms and leeks for 5 minutes to evaporate the liquid. Season with salt and pepper.
• Butter a large casserole dish. Arrange 1/3 of the sliced potatoes on the bottom of the pan, overlapping them slightly. Season the potatoes with chopped parsley, chives, salt and pepper. Top potatoes with half of the mushroom mixture. Repeat layering 1/3 of the potatoes and remaining mushroom mixture. Arrange remaining potatoes on top. Press the layers down with a spatula to condense. Remove the solids from the infused milk and pour over the potatoes. Sprinkle the surface with cheese. Cover the pan with foil and place in a preheated 375 degrees F oven. Bake for 1 hour until the potatoes are tender. Uncover and bake for 15 additional minutes until cheese melts and gratin is golden around the edges. Let stand 10 minutes before cutting. Garnish with fresh parsley.

WILD MUSHROOM AND POTATO GRATIN

Steps:

• Place the dried porcinis in a bowl or a pyrex measuring cup and pour on 1 1/2 cups boiling water. Soak for 30 minutes. Line a strainer with cheesecloth and place over a bowl. Drain mushrooms, then squeeze in cheesecloth to extract juices. Rinse several times and chop medium-fine. Measure out 1 cup of broth.
• Meanwhile heat oven to 375 degrees. Rub inside of a 3-quart gratin dish or baking dish all over with the cut half garlic clove and lightly oil with olive oil. Heat oil in a wide, heavy nonstick skillet over medium heat. Add onion or shallots and cook gently until just tender, 3 to 5 minutes. Turn up heat to high and add mushrooms. Cook, stirring, until they begin to sweat, 2-3 minutes, reduce heat to medium, and add minced garlic, thyme, rosemary or sage and dried porcinis. Cook, stirring, until fragrant, about 30 seconds. Season mushrooms with salt and pepper and continue to cook over medium heat until soft, about 5 more minutes. Add wine and cook, stirring, until it is no longer visible in the pan. Taste and adjust seasoning.
• In a large bowl combine potatoes, mushrooms, half the cheese, and salt and pepper. Arrange in an even layer in gratin dish.
• Combine milk and mushroom broth. Season generously with salt and pour over the potatoes and mushrooms. Press the vegetables down into the liquid. Bake 1 hour. Every 20 minutes remove gratin dish and press potatoes and mushrooms down into the liquid with the back of a large spoon. After 1 hour, sprinkle on remaining cheese and bake for another 30 minutes, until top is golden and the sides crusty. Remove from the oven and allow to sit for 10 to 15 minutes before serving. Serve hot or warm.

WILD MUSHROOM, POTATO & PANCETTA GRATIN

Steps:

• Put the garlic cloves, onion, bay leaves, thyme, double cream and milk in a pan. Bring slowly to the boil over a low heat, partially cover with a lid and cook for 20-30 mins until the onion is tender and the cream mixture slightly thickened. Turn off and leave everything to infuse for 1 hr.
• Strain the cream mixture into a jug (or bowl) and discard the herbs. Put the garlic cloves and onion in a food processor or blender and whizz until smooth - add a drop of the cream if it helps. Stir the paste back into the rest of the cream and season with 2 tsp salt.
• Put the pancetta in a cold frying pan and cook gently, over a low-medium heat so the fat melts into the pan, until the pancetta is really crispy. Lift out with a slotted spoon, add the butter and mushrooms and turn up the heat, frying the mushrooms, until golden and dry.
• Leave the skins on the potatoes and slice as thinly as possible. Grease a large baking dish with a little more butter. Layer up the potato slices, scattering over some of the cooked pancetta, the mushrooms and a little freshly grated nutmeg and pepper as you go. Finish by slowly pouring over the cream so that it settles among all the layers, then scatter over a few more thyme leaves. Cover with foil.
• Heat oven to 180C/160C fan/gas 4. Bake the gratin for 1 hr, then remove the foil and bake for 35-45 mins more until golden and crispy on top. Poke a knife in to check the potatoes are tender, then leave for 10-15 mins to settle, before serving with a salad, if you like.
