Turkish Sweet Potato Recipe: Cinnamon-Spiced Roast with Crispy Celery Crown

This Turkish sweet potato recipe transforms humble roots into a fragrant, crispy masterpiece that pairs perfectly with grilled meats or fresh yogurt. 🌟 The secret lies in a warm blend of cinnamon, allspice, and sumac—spices that create a sweet-savory harmony while the celery crown adds a satisfying crunch.

I developed this dish after discovering how Turkish home cooks elevate simple ingredients through slow roasting and aromatic spices.

The technique is straightforward yet transformative: sweet potatoes are roasted until tender and caramelized, then topped with crispy celery crowns that add texture contrast. This dish delivers restaurant-quality results with minimal effort—just 30 minutes of active prep and 45 minutes of hands-off roasting.

The spices infuse deeply, creating layers of flavor that make every bite memorable.

What you'll achieve is a dish that balances sweetness and warmth, with golden-brown sweet potatoes and crispy celery crowns that hold their shape. The aroma alone will draw everyone to the table, while the texture—tender yet slightly crispy—makes it irresistible.

This recipe is perfect for family dinners or holiday gatherings where you want to impress without stress.

Serve alongside grilled lamb, chicken, or even as a standalone side with a dollop of Turkish yogurt. The spices work their magic even better when made ahead, so the flavors have time to meld.

Let's create this aromatic centerpiece for your table—it's simpler than it looks, but the results are extraordinary.

Ingredients for turkish sweet potato

Six aromatic ingredients transform simple sweet potatoes into a Turkish-inspired centerpiece.

The sweet potatoes are the foundation—look for vibrant, firm roots with no soft spots. Trader Joe's and Whole Foods carry excellent organic varieties, but any medium-sized sweet potatoes work. Peeled and cubed evenly, they'll roast uniformly. Celery crowns require thick stems—avoid the thin, stringy kind from the middle of the stalk. For the spices, Penzeys offers premium Ceylon cinnamon and sumac, but grocery store brands are fine if freshly ground. The allspice should smell warm and peppery, not musty. Fresh thyme is ideal, but dried works at half the amount if you're in a pinch.

No sumac? Substitute lemon zest at half the amount for brightness, though it won't match the tangy complexity. Running short on pomegranate molasses? Substitute balsamic vinegar—it adds depth but lacks the fruity sweetness. The honey can be swapped for maple syrup, though wildflower honey has the most nuanced flavor. For a dairy-free option, omit the yogurt or use coconut yogurt. If your sweet potatoes are large, cut them into 1.5-inch cubes—they'll caramelize beautifully while staying tender inside. The celery crowns crisp best when cut into 1-inch pieces and tossed in olive oil before roasting.

Roasted sweet potatoes keep well for 4 days in the fridge, though they're best enjoyed within 2 days for maximum crispiness. Store them in an airtight container with a paper towel to absorb moisture. The celery crowns lose their crunch quickly—reheat only once in a dry skillet over medium heat for 2 minutes. For make-ahead prep, roast the sweet potatoes a day ahead and store at room temperature. The spices and honey mixture can be prepped 3 days ahead and kept in a sealed jar. When reheating, cover with foil for 5 minutes to restore moisture, then uncover for the final 2 minutes to crisp the edges.

Step-by-step instructions for Turkish sweet potato roast

This method delivers perfectly caramelized sweet potatoes with celery crowns that crackle like autumn leaves.

Preheat your oven to 425°F with racks positioned in the upper and lower thirds. Line two large baking sheets with parchment paper—this prevents sticking and makes cleanup effortless. While the oven heats, toss the 3 lbs sweet potatoes (already peeled and cubed) with ½ cup extra-virgin olive oil until evenly coated. Spread them in a single layer on one baking sheet, leaving ½-inch gaps between pieces for even browning.

For the celery crowns, trim the 2 bunches celery stems to remove the leafy tops, leaving just the thick, pale bottom sections. Cut these into 1-inch pieces and toss them with 1 tablespoon olive oil reserved from the sweet potatoes. Arrange the celery pieces in a single layer on the second baking sheet, again leaving space between each piece. The key here is surface area—more contact with hot air means better crisping.

In a small bowl, whisk together 1.5 tablespoons ground cinnamon, 1 teaspoon ground allspice, 1 tablespoon sumac, and 1.5 teaspoons sea salt. Sprinkle this spice blend evenly over the sweet potatoes, pressing gently so it adheres. For the celery, combine ¼ cup chopped fresh thyme leaves and 4 minced garlic cloves with the remaining ¼ cup olive oil, then toss the celery pieces in this mixture. Spread the thyme-garlic oil evenly over the celery.

Roast both trays simultaneously for 25 minutes, then rotate the sheets front-to-back and top-to-bottom. This ensures even cooking—you'll see the sweet potatoes start to caramelize and the celery develop golden-brown edges. After another 20 minutes, check for doneness: the sweet potatoes should be tender when pierced with a fork, and the celery should be crisp with deep brown spots. If any pieces need more time, return them to the oven for 5-10 minutes.

Remove the sweet potatoes from the oven and transfer them to a large bowl. In a small saucepan over low heat, combine 2 tablespoons honey and 1 tablespoon pomegranate molasses with 2 tablespoons water. Simmer for 3-4 minutes until the mixture thickens slightly and becomes syrupy. Pour this glaze over the hot sweet potatoes and toss gently to coat evenly. The residual heat will help the glaze adhere without steaming the vegetables.

Return the sweet potatoes to the oven for 5-7 minutes to let the glaze caramelize and develop a glossy sheen. Watch closely—they should darken to a deep amber color with sticky spots. Meanwhile, remove the celery from the oven and transfer it to a serving platter. The celery should be crisp with a slight char—this is the hallmark of perfect texture.

Transfer the glazed sweet potatoes to the same platter as the celery, arranging them alongside the crispy crowns. Drizzle any remaining glaze from the bowl over the top for extra shine. For serving, dollop ½ cup plain Greek yogurt around the platter or serve it on the side for dipping. The yogurt's cool creaminess balances the warm, spiced sweetness of the roast.

This dish shines when served immediately, while the celery is still crisp and the sweet potatoes maintain their caramelized glaze. For best results, serve directly from the platter so guests can mix the components as they please. The contrast of textures—creamy sweet potatoes, crispy celery, and smooth yogurt—makes every bite satisfying. Store leftovers in an airtight container for up to 3 days, though the celery will lose its crispness when reheated.
