CHEESY ROOT VEGETABLE GRATIN

Steps:

• Preheat oven to 400˚F. Grease a 3 quart baking dish with butter.
• Slice sweet potato, parsnips and beets into very thin rounds (using a mandoline is easiest) and transfer each vegetable to its own bowl.

Season each bowl generously with salt and pepper and toss together until all vegetable slices are well coated.

• Grab a stack of sweet potatoes and line them standing up on a bias, at the top of the baking dish. Follow the sweet potato with a row of parsnips, followed by a row of beets. Repeat with the remaining sweet potatoes, parsnips and beets, creating 6 rows of root vegetables.
• Season top of gratin with salt, pepper and sprinkle of remaining Parmesan.
• Cover with foil and bake for 30 minutes or until vegetables are soft.
• Uncover gratin and top with shredded gruyere.
• Place gratin back into oven, uncovered, and continue to bake for an additional 18 to 20 minutes or until vegetables are fork tender, cheese has melted and the top has lightly browned.
• Finish with a sprinkle of fresh thyme leaves. Serve.

Sprinkle half of each of the cheeses evenly over vegetables in skillet.

SWEET POTATO AND ROOT VEGETABLE GRATIN

Steps:

• Preheat oven to 350 degrees. Rub a small amount of the olive oil on the bottom of a casserole dish 81/2 inches. Shingle rutabaga slices to cover the bottom of the casserole overlapping the slices by no more than 1/2-inch. Sprinkle lightly with salt and pepper. Thinly slice one of the potatoes* lengthwise and shingle the potatoes over the rutabaga then season lightly with salt and pepper. Pat or mist lightly with some of the oil. Spread 1/3 of the onions evenly over the potatoes. Layer the parsnip over the onions, then more potatoes. Pat or mist lightly with some of the oil. Season lightly with salt and pepper. Repeat the layering and seasoning with rutabaga, the potato, then onion, and finally potato. If there are any root slices left over, alternate rows of roots and potatoes on the final layer. Pat or mist lightly with oil, season with salt and pepper, cover tightly and place in the oven. Bake for 45 minutes. Remove the cover, pat or mist lightly with the remaining oil, then sprinkle over with the chopped herbs. Bake, uncovered for another 15 to 20 minutes or until the top layer browns nicely. Allow to set 10 to 15 minutes then slice and serve.
• *Slice the potatoes to retain their starch and nutrients. This also will prevent then from browning.

SO-CAL SWEET POTATO AND POTATO GRATIN

Steps:

• If you have a gas burner, roast the poblano peppers over the open flame, turning occasionally with tongs, until the peppers are well charred all over, about 4 minutes. If you do not have a gas burner, halve the peppers lengthwise, place them in a baking pan and broil them in a preheated broiler, skin-side up, until well charred. Place the charred peppers in a bowl and cover with plastic wrap for 10 minutes. Peel, stem and deseed the peppers, then cut into strips.
• Preheat the oven to 400 degrees F. Butter a 9-by-13-inch baking dish.
• Stir together the cream, salt, lime zest, cumin and garlic in a bowl.
• Peel the sweet potatoes and russet potatoes and thinly slice them with a mandoline (about 1/4-inch thick).
• Arrange half of the russet potatoes in the buttered baking dish. Top with half of the sliced poblanos, then half of the sweet potatoes. Top with half of the cream mixture and 1/3 cup Cotija. Repeat with the remaining ingredients (potatoes, poblanos, sweet potatoes, cream and the remaining 2/3 cups Cotija) and press down firmly to submerge the potatoes as much as possible.
• Cover the baking dish tightly with foil and bake for 35 minutes. Uncover and continue to bake until the potatoes are tender, the liquid has absorbed, and the top is browned in spots, 25 to 30 minutes more.
• Let stand 10 minutes before serving.

Steps:

• Preheat the oven to 350 degrees. Butter a 13-by-10-by-2 1/2-inch oval baking dish.
• Heat 2 tablespoons of olive oil in a large (12-inch) saute pan over medium heat, add the onion and fennel, and cook for 10 minutes, tossing occasionally, until lightly browned and tender. Add the garlic and cook for one minute.
• Meanwhile, in a large bowl, combine the onion mixture, sweet potatoes, celery root, Yukon Gold potatoes, cream, chicken stock, Gruyere, thyme, 1 tablespoon salt, and 1 1/2 teaspoons pepper. Pour the mixture into the prepared baking dish and press lightly so the vegetables lie flat all the way to the edge. Combine the bread crumbs and 2 tablespoons of olive oil and distribute evenly on top. Bake uncovered for 1 1/2 hours, until the vegetables are very tender when tested with a small knife and the top is browned and bubbly. Allow to set for 15 minutes and serve hot.

Steps:

• Preheat the oven to 400 degrees. Butter a 2-quart gratin or baking dish. Place the sliced vegetables in a large bowl, and season generously with salt and pepper. Add the thyme, and toss together.
• Arrange the vegetables in the gratin dish. Add the milk, season with more salt and pepper if you wish, and place in the oven on the middle rack. Bake 45 minutes; every 15 minutes, press the vegetables down into the milk with the back of your spoon.
• Add the cheese, and stir in carefully to incorporate. Return to the oven, and bake another 30 to 45 minutes, stirring or pressing the vegetables down with the back of your spoon every 10 minutes until the gratin is nicely browned and most of the liquid is absorbed. Remove from the heat and serve, or allow to settle and serve warm. (You can make this several hours ahead of serving, and reheat in a medium oven.)

ROOT VEGETABLE GRATIN

Steps:

• Put oven rack in upper third of oven and preheat oven to 400°F.
• Peel parsnips and cut crosswise into 3-inch lengths with a knife, then cut lengthwise around core into 1/8-inch-thick slices with slicer (discard core). Transfer to a large bowl.
• Peel celery root and all potatoes (prepare russet potatoes last to avoid discoloration) and halve lengthwise, then cut crosswise into 1/8-inch-thick slices with slicer. Add to parsnips along with salt, garlic, pepper, nutmeg, broth, and 1 3/4 cups cream, tossing to combine. Transfer to gratin dish, spreading evenly.
• Cut out a piece of parchment or wax paper to fit just inside gratin dish, then butter 1 side of parchment. Cover vegetables directly with parchment, buttered side down, then put dish in a shallow baking pan (to catch any drips). Bake until gratin is bubbling all over and vegetables are tender when pierced with a knife, about 50 minutes. Discard parchment.
• Just before serving, preheat broiler. Drizzle top of gratin with remaining 2 tablespoons cream and broil 4 to 6 inches from heat until browned, 2 to 3 minutes.
