FANTASTIC MUSHROOMS AU GRATIN

Steps:

• Preheat oven to 400 degrees F.
• Grease a shallow baking dish.
• In a medium skillet saute the sliced mushrooms with butter over medium-high heat (if using garlic add in with the mushrooms).
• In a small bowl, blend together sour cream, salt, pepper and flour.
• Add to the mushrooms in the pan.
• Heat until JUST beginning to boil.

SPINACH AND MUSHROOM GRATIN

Steps:

• Preheat the oven to 350°F (180°C). Halve or quarter the mushrooms, depending on their size. Warm the butter and 2 tablespoons of oil in a deep pan and add the mushrooms, letting them color nicely here and there (expect to add more oil if they drink it all). Pour in the wine and bring to a boil. Continue to boil for a couple of minutes.
• Pour the cream into the pan and let it come back to a boil, then simmer for two minutes. Turn off the heat. Wash the spinach and put it, still wet from rinsing, into a pan with a tight-fitting lid. Let the spinach cook for a minute or two in its own steam, then drain it and squeeze to remove excess water.
• Reserve several tablespoons of the Parmesan. Fold together the mushrooms, drained spinach, salt and black pepper, and the rest of the grated Parmesan. Put into a shallow baking dish. Scatter the reserved cheese on top and bake for thirty-five minutes, until the top is crisp and golden.

MUSHROOM AND ONION GRATINS

Steps:

• In a skillet cook the mushrooms in 2 1/2 tablespoons of the butter over moderately low heat, stirring, until they are softened and most of the liquid they give off has evaporated. Stir in the flour and cook the mixture, stirring, for 3 minutes.
• In each of six 1 1/2-cup gratin dishes layer the onions, the remaining butter, cut into bits, the mushroom mixture, and salt and pepper to taste, beginning and ending with a layer of onions, and pour 1 tablespoon of the cream over the top of each gratin. In a small bowl combine well the Gruyère and the bread crumbs and sprinkle the mixture over the cream. (Alternatively, the gratin, layered in the same manner, may be prepared in one 2-quart gratin dish.) Bake the gratins in the middle of a preheated 325°F. oven for 50 minutes to 1 hour, or until the onions are tender and the tops are golden. The gratins may be prepared 3 hours in advance, kept covered and chilled, and reheated in a preheated 400°F. oven for 5 minutes, or until they are heated through.

MUSHROOM AND GREENS GRATIN

Steps:

• Preheat the oven to 375 degrees. Oil a 2-quart baking dish or gratin.

• Heat the olive oil over medium heat in a large nonstick skillet, and add the shallots or onion. Cook, stirring, until tender, three to five minutes. Add the mushrooms, and cook, stirring often, until tender, about eight minutes. Add salt and pepper to taste, and the rosemary and garlic. Cook for another minute. Add the greens, and stir together for another minute. Adjust seasonings.

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.

FARRO AND MUSHROOM GRATIN

Steps:

• Heat oven to 425 degrees. Bring a medium pot of well-salted water to a boil over high heat.
• Add farro to the pot, and cook according to package directions until tender (which should be about 20 to 30 minutes). Drain well in a colander. While still warm (and leaving the farro in the colander, if you like), drizzle the grains with enough olive oil to coat lightly, tossing well to prevent from sticking. Set aside.
• While farro is cooking, prepare the mushrooms: In a large ovenproof skillet, heat 3 tablespoons of the oil over medium-high until hot but not smoking. Add enough of the mushrooms to cover the skillet in one layer without crowding and half the thyme. Cook, undisturbed, until bottoms of the mushrooms are golden brown, 3 to 5 minutes. Stir and let brown on the other side, 2 to 3 minutes more. Use a slotted spoon to transfer mushrooms and thyme to a plate, and season with salt and pepper. Add another 2 tablespoons oil to the pan and repeat with another layer of mushrooms and thyme, adding them to the plate when done. Repeat with any more mushrooms if necessary.
• Add remaining 1 tablespoon oil to skillet and stir in shallots and a large pinch of salt and pepper. Sauté until tender and golden brown, 4 to 6 minutes.
• Remove skillet from heat and return mushrooms to the pan (discarding the thyme sprigs). Stir in farro, mascarpone and 3/4 cup parsley. Taste and add more salt and pepper, if needed. Spread mixture evenly in the skillet and sprinkle Gruyère on top. Bake until the farro is hot and Gruyère is melted, 10 to 15 minutes. Turn on broiler and broil for 1 to 2 minutes until Gruyère starts to bubble and develop brown spots.
• Sprinkle with remaining parsley and serve with lemon wedges for squeezing on top, if you'd like.
