ROOT VEGETABLE GRATIN FROM REYNOLDS WRAP®

Steps:

• Preheat oven to 350 degrees F. Line a baking sheet with two long sheets of Reynolds Wrap® Aluminum Foil, overlapping them in opposing directions so you make a cross, with plenty of foil at each end to eventually fold over into the center. Lightly spray with cooking spray and set aside.
• In a large mixing bowl, stir together cream, shallot and garlic. Add parsnips, sweet potato and turnip and carefully toss together until all the pieces are well coated. In another mixing bowl combine 1 cup of the grated cheese, green onion, and thyme and toss together.
• To assemble, place a single layer of cream-coated root vegetable pieces onto the foil-lined baking sheet and season generously with salt and pepper. Sprinkle 1/4 of the cheese mixture over the surface. Repeat with another layer of vegetables, salt and pepper and cheese mixture and continue with this pattern until all the ingredients have been used (finishing with a layer of vegetables).
• Bring each side of the excess foil hanging over the baking sheet together and seal tightly, leaving room for heat circulation inside. Bake gratin in the oven for 40 to 45 minutes or until vegetables are fork tender. Open foil carefully by cutting along top fold with a sharp knife, allowing steam to escape; then open top of foil.
• Uncover gratin and sprinkle remaining cheese over the top. Place gratin under a broiler and broil for 30 seconds to 1 minute or until cheese has melted and the top has browned slightly. Allow gratin to cool for about 10 minutes before cutting up and serving.

AUTUMN ROOT VEGETABLE GRATIN

Steps:

• Heat the oven to 400° F. Put the milk in a small heavy saucepan and peel and smash one of the garlic cloves. Add it to the milk and then heat the milk over low heat until it just starts to bubble at the edges. Remove from the heat, add the nutmeg and let steep while you continue with the recipe.
• Peel the second garlic clove, cut it in half and rub the cut side around the inside of a 6-cup baking dish no more than 2 inches deep. Rub 1 tablespoon of the oil all over the inside of the dish.
• Peel the squash, potatoes and parsnips and cut them into very thin slices (1/8-inch thick). If you have a mandoline, now's the time to use it.
• Layer the vegetables into the baking dish, alternating between squash, potato and parsnip, and fanning them into concentric, overlapping circles. Season generously with salt and pepper and sprinkle a third of the cheese and a third of the chopped herbs over the slices. Repeat twice, making the top layer as neat and tidy as you can.
• Remove the garlic clove from the hot milk and pour the milk evenly over the vegetables. Drizzle the remaining olive oil over the top of the gratin and bake for about 50 minutes, until the top is browned and bubbly and the vegetables yield easily when you poke them with a sharp knife. If the vegetables are tender but the top isn't as brown as you'd like, turn on the broiler for a couple of minutes -- watch it carefully so it doesn't burn! Let the gratin cool for at least 5 minutes before serving.

HERBY ROOT VEGETABLE GRATIN

Steps:

• Meanwhile, blend the herbs, garlic, most of the Parmesan and some seasoning in a food processor. Add the oil and blend again to form a paste.
• Tip a third of the creamy veg into a buttered baking dish, dollop over half the herb mix and spread out a little. Top with another third of the veg, followed by the remaining herb mix, then the rest of the vegetables. Dot the surface with the remaining butter and scatter over the reserved Parmesan. Bake for 1-1½ hrs until bubbling and golden, covering with foil for the final 30 mins if it's becoming too brown. Leave to rest for 10-15 mins before serving.

• 1. Heat the oven to 400 degrees F. Spread the butter in a 13 x 9 x 2-inch baking dish.
• 2. Add the squash, potatoes, celery root, and leeks to the prepared dish.
• 3. Heat the broth, cream, thyme and nutmeg in a 2-quart saucepan over medium heat to a boil. Season to taste.

• 6. Bake for 25 minutes. Reduce the temperature to 350 degrees F and bake for 40 minutes more or until golden brown and the vegetables are tender.
• 7. If the vegetables are browning too fast in the first 25 minutes, cover the dish loosely with foil.
• 8. Sprinkle with the cheese. Let stand for 10 minutes.

ROOT VEGETABLE GRATIN

Steps:

• Preheat oven to 400 degrees F. Coat a 9-by-13-inch baking dish with cooking spray.
• If using parsnips, quarter lengthwise and remove the woody core before cutting into 1/8-inch thick slices. Cook vegetables in a large pot of boiling water until barely tender, about 5 minutes. Drain.
• Heat 2 tablespoons oil in a medium saucepan over medium heat. Add shallots and cook, stirring occasionally, until light brown, 3 to 4 minutes. Add 1 cup milk and bring to a simmer. Combine flour and the remaining 1/3 cup milk in a small bowl to make a smooth paste; stir into the hot milk and cook, whisking constantly, until the sauce bubbles and thickens, 1 to 2 minutes. Remove from the heat. Stir in 3/4 cup cheese, thyme, salt and pepper.
• Combine breadcrumbs, the remaining 3/4 cup cheese and 1 tablespoon oil in a bowl.
• Layer the vegetable slices in the prepared baking dish. Pour the cheese sauce over the top and top with the breadcrumb mixture.
• Bake the gratin until it is bubbling and the top is golden, 30 to 40 minutes. Let cool for 10 minutes before serving.
• Tips: Beets, carrots and parsnips are easily peeled with a vegetable peeler, but for tougher-skinned roots like celeriac, rutabaga and turnips, removing the peel with a knife can be easier. Cut off one end of the root to create a flat surface to keep it steady on the cutting board. Follow the contour of the vegetable with your knife. If you use a vegetable peeler on the tougher roots, peel around each vegetable at least three times to ensure all the fibrous skin has been removed.
• To make fresh breadcrumbs, trim crusts from country-style whole-wheat bread. Tear bread into pieces and process in a food processor until coarse crumbs form. One slice of bread makes about 1/2 cup crumbs.

When all the veggies have been layered, pour in the milk to come halfway up the vegetable layers. Cover with foil and bake 30 minutes at 350 degrees. Remove the foil, dot the top of the casserole with the goat cheese, and bake 30 minutes more, or until vegetables are soft, cheese has turned golden, and the casserole is bubbly. Let it sit for 10 minutes, then sprinkle with the parsley and serve directly from the casserole.
