Roasted Portobello And Potato Gratin Recipes

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.

PORTOBELLO GRATIN

Steps:

• Split 6 portobello mushroom caps to make 12 thin rounds. Toss 1 1/4 cups shredded muenster cheese, 1/3 cup breadcrumbs, 2 tablespoons chopped parsley, 1 grated garlic clove, and salt and pepper. Layer the portobello rounds and cheese mixture in a baking dish, making 3 layers of each. Drizzle with 3 tablespoons water, cover with foil and bake at 400 degrees F, 35 minutes. Uncover and bake 8 more minutes.

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.)
• *Dried porcini mushrooms are available at Italian markets, specialty foods stores and many supermarkets.

ROASTED PORTOBELLOS WITH PESTO

Steps:

• Preheat the oven to 400 degrees Fahrenheit. Remove the stems of the mushrooms, and carefully scrape away the gills using a spoon. Toss with the olive oil and season with salt and pepper. Place, rounded side down, on a lightly oiled baking sheet. Place in the oven and roast for 8 to 10 minutes, until the mushrooms are beginning to soften and throw off liquid. Remove from the heat and fill with the pesto. Return to the oven and continue to roast until thoroughly softened, about 10 more minutes.

PORCHETTA-SPICED ROASTED POTATOES

Steps:

• Heat oven to 425 degrees. On a rimmed baking sheet, combine 2 tablespoons of the oil and potatoes, and season with salt; toss to evenly coat. Spread in an even layer and roast until light golden, 20 minutes.
• Meanwhile, in a small bowl, combine the remaining 3 tablespoons oil, garlic, fennel, thyme, rosemary, sage, black pepper and red-pepper flakes, and season to taste with salt; mix well.
• Spoon the herb mixture over the potatoes and toss until evenly coated, using a spatula to lift up the potatoes if necessary. Continue roasting until the potatoes are fragrant, golden brown and tender when pierced with a fork, 10 to 15 minutes longer.
• Transfer potatoes to a serving platter and garnish with parsley. Serve warm.

POBLANO POTATO GRATIN

Steps:

• Roast chiles and make rajas:
• Roast chiles on their sides on racks of gas burners on high, turning with tongs, until skins are blackened all over, about 10 minutes. Immediately transfer to a bowl and let stand, covered tightly, 10 minutes.
• When chiles are cool enough to handle, peel or rub off skin. Slit chiles lengthwise, then stem, seed, and devein. Cut lengthwise into thin strips.
• Cook onions with 1 teaspoon salt in oil in a 12-inch heavy skillet over medium-low heat, stirring occasionally, until golden, about 8 minutes. Stir in chiles and remove rajas from heat. Reserve 1/2 cup rajas for topping.
• Make gratin:
• Preheat oven to 400°F with rack in middle. Generously butter a 3-quart shallow baking dish.
• Peel potatoes, then cut crosswise into 1/16-inch-thick slices with slicer. Transfer to a small heavy pot. Add cream, milk, and 1 teaspoon salt and bring just to a boil over medium heat, stirring occasionally (liquid will thicken). Stir in rajas, then pour mixture evenly into baking dish. Sprinkle reserved 1/2 cup rajas on top.
• Bake until potatoes are tender, 45 minutes to 1 hour. Let stand 15 minutes before serving.
