Sweet Potato And Vegetable Tian Recipes

POTATO-ONION TIAN

Steps:

• Preheat the oven to 425˚. Brush a 3-quart oval baking dish with olive oil. Toss the potatoes with 1 tablespoon olive oil, the thyme, 1/2 teaspoon salt and a few grinds of pepper in a large bowl. In a separate bowl, toss the onion and leek slices, keeping them intact, with 1 tablespoon olive oil and a big pinch each of salt and pepper.
• Arrange the potatoes, onion and leek in overlapping layers in the prepared dish. Drizzle with the remaining 1/4 cup olive oil and season with 1/2 teaspoon salt. Cover with foil and bake until the vegetables are very tender, about 45 minutes. Uncover and bake until the potatoes are lightly browned and crisp around the edges, 30 to 40 more minutes. Let stand about 10 minutes before serving.

POTATO AND SWEET POTATO TIAN

Steps:

• Preheat oven to 350 degrees. Toss together potatoes, sweet potatoes, apple, leeks, oil, and 1 teaspoon salt. Season with pepper. Transfer to a 9-by-12-inch oval baking dish, spread into a thin layer, and cover with parchment-lined foil. Bake for 15 minutes. Raise oven temperature to 400. Remove, uncover, and top with Gruyere. Bake until bubbling and top is browned, about 30 minutes.

SWEET-POTATO-AND-SAGE TIAN

Steps:

• Preheat oven to 375°F. Brush butter evenly over bottom and sides of a 9-by-12-inch oval baking dish, 8-by-10-inch rectangular baking dish, or other shallow 2-to-2 1/2-quart dish. Sprinkle 1/2 cup cheese evenly over butter; season with ground pepper.
• Combine half-and-half, 20 sage leaves, garlic, and peppercorns in a large saucepan; season with 1 tablespoon salt. Bring to a boil, then reduce heat to medium and simmer until reduced by half, 15 to 20 minutes. Strain, discarding solids; season to taste.
• Meanwhile, slice sweet potatoes into 1/8-inch-thick rounds. Snugly arrange slices vertically in prepared baking dish. Tuck remaining 12 sage leaves between potatoes; carefully pour half-and-half mixture over top. Sprinkle top with remaining 1/2 cup cheese and lightly drizzle with oil.
• Roast until potatoes are tender and top is golden brown, 55 to 65 minutes. (If top is browning too quickly, tent with foil.) Let cool at least 15 minutes before serving.
