The classic Provençal tian—a gratin of layered sliced vegetables served right from the vessel it’s baked in—gets a Chinese American twist, courtesy of recipe developer and fashion designer Peter Som. In this recipe, a favorite on his Thanksgiving table, Som uses thinly sliced rounds of sweet potato tossed in brown butter spiked with ginger, miso, dark soy sauce, and five-spice powder. “Made of fennel seeds, cinnamon, cloves, star anise, and Sichuan peppercorns, five-spice is infinitely versatile,” he says. “It brings warmth to whatever I’m making. I like to say it’s pumpkin spice’s bolder cousin.” Stacking the slices so they stand upright on their sides (rather than flat against the pan) exposes their edges to the heat of the oven, allowing them to become crispy and intensely flavorful. If you can’t find dark soy sauce, you can substitute 2 Tbsp. regular soy sauce plus ¼ tsp. granulated sugar.

For the rest of Som’s Thanksgiving menu, see his recipes for Asian Pear Salad With Peanut-Lime Dressing, Roasted Brussels Sprouts With Gochujang Brown Butter, Dutch Oven No Mai Fan, Char Siu Wellington, and Milk Tea Bread Pudding With Crème Anglaise.

Recipe information

  • Yield

    8 Servings

Ingredients

6

Tbsp. unsalted butter, plus more for pan

3

garlic cloves, finely grated

1

1" piece ginger, peeled, finely grated

1

Tbsp. finely grated orange zest

¼

cup fresh orange juice (about 1 orange)

¼

cup low-sodium vegetable broth

¼

cup light brown sugar

2

Tbsp. dark soy sauce

1

Tbsp. white miso

2

tsp. Diamond Crystal or 1¼ tsp. Morton kosher salt

2

tsp. five-spice powder

½

tsp. freshly ground black pepper

1

Tbsp. thyme leaves, plus more for serving

4

lb. medium sweet potatoes, unpeeled, sliced ⅛" thick

Preparation

  1. Step 1

    Place a rack in middle of oven; preheat to 350°. Butter a 10" cast-iron skillet or a 2½-qt. shallow round or oval baking dish. Melt 6 Tbsp. butter in a small saucepan over medium heat and cook, stirring often, until butter foams, then browns (do not burn) and smells nutty, 5–8 minutes.

    Step 2

    Remove saucepan from heat and whisk in garlic, ginger, orange zest, orange juice, broth, brown sugar, soy sauce, miso, salt, five-spice powder, pepper, and 1 Tbsp. thyme.

    Step 3

    Combine sweet potatoes and brown butter mixture in a large bowl and toss gently until sweet potatoes are thoroughly coated.

    Step 4

    Stack sweet potato slices upright on their edges in vertical rows along perimeter of skillet, following the curve of the pan. Arrange more vertical rows of sweet potatoes down center of skillet to cover entire pan. Be sure to pack sweet potatoes tightly and fill in any gaps with smaller sweet potato slices. Pour any remaining brown butter from bowl over sweet potatoes, then cover skillet tightly with foil.

    Step 5

    Bake sweet potatoes until fork-tender, 50–60 minutes. Carefully remove foil and increase oven temperature to 425°. Continue to bake until tops of sweet potatoes are deep golden brown, 30–40 minutes longer.

    Step 6

    Scatter more thyme over tian and let cool slightly before serving.

    Do Ahead: Tian can be baked 1 day ahead. Let cool; cover tightly with foil and chill. Reheat, loosely covered with foil, in a 350° oven until heated through, 40–45 minutes.

  • Delicious. I didn’t have a cast iron skillet so used a ceramic pie pan. I couldn’t find garlic so replaced them with a diced onion. I had a jar of red miso so used it. After turning up the oven, the crust burnt so I discontinued baking after 20 minutes. I would use it anytime other than Thanksgiving or Christmas.

  • Very pretty presentation but the taste was not great - had way too much leftovers vs candied sweet potatoes - might try with candied recipe but with the slices

  • Perhaps sliced a tad too thin, but was able to make a pretty rosace and the flavor is insane! A keeper!

  • This was wonderful. A big hit at Thanksgiving with friends. I used 2 kinds of sweet potatoes so it looked like a flower. Will definitely make it again.

  • This looks great! I plan to make it this coming week before Thanksgiving when we have company for dinner. We love sweet potatoes and I am always looking for new ways to prepare them. And a note to GLEE in Kailua, HI - I agree, sweet potatoes are really hard. I plan to use my mandoline, which is really sharp, to slice them. It can slice from 1/8 inch to 1/4 inch slices. I never thought I needed one until I got this one as a gift many years ago - now I use it all the time!

  • A huge hit! The depth of flavor was amazing and it was not complicated to make. This will be my new go-to sweet potato dish for Thanksgiving/Friendsgiving.
