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.

ROASTED PORTOBELLO AND POTATO GRATIN

Steps:

• Heat oven to 400 degrees. Line a baking sheet with sides with a sheet of parchment. Place mushrooms gill side up on parchment. Thinly slice 3 garlic cloves, and scatter over mushrooms. Place a thyme sprig on each mushroom, drizzle caps with olive oil, salt and pepper, and place in oven until soft and releasing liquid, 10 to 15 minutes. Remove, and allow to cool. Keep oven on.
• Heat 1 tablespoon butter in a skillet, add onions, and sauté over medium-low heat until soft and beginning to color. Add cream and milk, scald, and remove from heat. Use remaining butter to grease a 9-inch gratin dish about 2 inches deep. Rub dish with remaining garlic clove.
• Remove and reserve garlic from mushrooms. Discard thyme. Slice mushrooms 1/2 inch thick.
• Peel and thinly slice potatoes. Place 1/3 of the potatoes in gratin dish, season with salt, pepper and nutmeg, scatter with half the reserved sliced garlic. Arrange half the mushroom slices on top. Repeat layers. Layer last third of potatoes on top. Season with salt and pepper. Pour scalded milk and cream with onions on top. Strew bread crumbs on top.
• Place gratin dish on a baking sheet, and place in oven. Bake about 1 hour, until potatoes are tender and liquid has thickened. If top browns too fast, tent with foil. Allow to stand 10 minutes, then serve.

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.

POTATO AND PORTOBELLO MUSHROOM GRATIN

Steps:

• Combine 1 1/2 cups hot water and porcini in small bowl. Let stand until mushrooms soften, about 30 minutes. Drain, reserving 2/3 cup soaking liquid. Chop porcini; set aside. Remove and chop stems from portobellos; place in large bowl. Using small spoon, scrape away dark gills from portobellos and discard. Cut portobello caps into 1/2-inch pieces; add to bowl.
• Heat 3 tablespoons olive oil in heavy large skillet over medium-high heat. Add chopped portobello stems and caps and sauté 4 minutes. Stir in garlic and reserved porcini and sauté until mushrooms are tender, about 10 minutes. Season with salt and pepper. Remove from heat.
• Preheat oven to 375°F. Coat each of two 13x9x2-inch glass baking dishes with 1 tablespoon oil. Combine remaining 7 tablespoons oil, potatoes, parsley, thyme, rosemary, salt and pepper in large bowl; toss to coat. Layer 1/6 of potato mixture in each prepared dish (there will not be enough to overlap slices). Top potatoes in each with 1/4 of mushroom mixture. Repeat layering. Top with remaining potatoes. Pour 1/3 cup reserved porcini soaking liquid over potatoes in each dish. Cover dishes with foil.
• Bake gratins 45 minutes. Uncover and bake until tops are brown and potatoes are tender, about 40 minutes longer. (Can be prepared 2 hours ahead. Let stand at room temperature. Cover with foil and rewarm in 350°F oven about 20 minutes.)
