POTATO/PORTOBELLO GRATIN

Steps:

• Heat oven to 400ºF. Butter a 9-by-13-inch baking dish and set aside.
• Using a mandoline 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 in the baking dish. 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 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.)

Using a spoon with a serrated edge, scrape out the fibrous choke from the center. Rub the artichoke all over with lemon and drop it into lemon water. Drain before using.
• Slice artichoke hearts. Arrange half of potatoes in dish, covering bottom completely. Top with half of artichoke hearts and half of mushrooms. Coarsely crumble half of goat cheese over. Sprinkle with half of garlic, salt, and pepper, then 1 tablespoon Parmesan. Drizzle with 1 tablespoon oil.
