This Sweet Potato and Sage Tian is made with thinly sliced sweet potatoes, sage leaves, garlic, and cream. The ingredients are layered in a baking dish and then baked until the sweet potatoes are tender and the cream is thickened. This is a dish that is deeply rooted in Provençal cuisine. It is often served during fall and winter when sweet potatoes are in season. The tian is a symbol of Provençal hospitality and is often served at family gatherings and special occasions.

  • Prep: 25 mins
  • Cook: 1 hr 20 mins
  • Yields: 8 Servings

Ingredients

3 tablespoons unsalted butter, softened


4 ounces Parmigiano-Reggiano, finely grated (1 cup)


Kosher salt and freshly ground pepper, plus

7 whole black peppercorns


5 cups half-and-half


32 fresh sage leaves (from 1 bunch)


4 cloves garlic, smashed


3 pounds sweet potatoes, such as Jewel, Garnet, or Beauregard, unpeeled

Extra-virgin olive oil, for drizzling

Directions

1Preheat oven to 375°F.

2Brush 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-2½-quart dish. Sprinkle ½ cup cheese evenly over butter; season with ground pepper.

3Combine 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.

4Meanwhile, slice sweet potatoes into ⅛-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 ½ cup cheese and lightly drizzle with oil.

5Roast 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.

What a marvelous looking recipe. I don’t believe I’ve ever had sweet potatoes treated with any method like this. I’ll have to try it and report back. Looks perfect for the Thanksgiving/Christmas season.
