This vibrant spiced sweet potato and parsnip tian is a sophisticated vegetarian centrepiece that brings a wonderful depth of flavour to any seasonal table. By slow-roasting the vegetables in a fragrant reduction of apple cider, butter, and earthy Aleppo pepper, the natural sweetness of the root vegetables is perfectly balanced with a gentle, aromatic heat. The concentric circular arrangement creates an eye-catching pattern that looks beautiful when brought straight from the oven to the centre of the dining table.
An ideal choice for a festive dinner or a special Sunday roast, this dish is as practical as it is impressive. The preparation can be started up to two days in advance, allowing the potatoes and parsnips to soak up the spiced glaze before a final blast in a hot oven to achieve those signature crisp, golden edges. Serve it alongside a crisp green salad or as a hearty accompaniment to your favourite winter mains.

110g (1 stick) unsalted butter
2 tablespoons thyme leaves

2.9kg sweet potatoes (about 8 medium), peeled, sliced into 1/8"-thick rounds

How to make Spiced Sweet Potato and Parsnip Tian
Back to contentsPosition rack in middle of oven and preheat to 163°C. Bring cider to a boil in a large saucepan over medium-high heat. Reduce heat to low, add butter, thyme, Aleppo, and 2 teaspoons salt, and cook, stirring, until butter is melted. Let cool slightly.
Place potatoes and parsnips in a large bowl. Pour cider mixture over and toss to coat. Stack a handful of slices about 3" high, then place vertically in casserole dish. Using a measuring cup or small bowl, keep slices standing up as you go, working around the perimeter and then into the centre, forming concentric circles. Continue arranging slices in pan until tightly packed (you may have some leftover). Pour in cider mixture to come halfway up sides of dish; discard remaining cider mixture. Sprinkle with remaining 2 teaspoons salt and cover tightly with foil.
Bake, covered, 1 hour. Remove foil and brush pan juices over tops of slices with a pastry brush. Increase oven temperature to 218°C and bake, uncovered, until golden brown on top, 35–40 minutes more.
After first round of baking at 163°C, let cool, then chill for up to 2 days. Bring to room temperature, then bake, uncovered, at 218°C for 40–50 minutes.
