Side Dishes
This sweet potato kabab recipe transforms humble sweet potatoes into restaurant-worthy skewers with a crispy celery crown that adds texture and visual appeal. The secret lies in cubing the potatoes just right—boiled until tender but firm enough to hold shape on the skewer—before grilling to develop that signature smoky char.
I've perfected this technique for both outdoor grills and indoor ovens, ensuring consistent results every time.
The magic happens when you thread the sweet potato cubes onto skewers with celery sticks at the top, creating those coveted crispy crowns. A light brush of olive oil and a sprinkle of smoked paprika before grilling enhances the natural sweetness while adding depth.
What you end up with is a dish that's equally satisfying as a main course or side—caramelized edges, tender centers, and that irresistible crunch from the celery.
Perfectly balanced between sweet and smoky, these kababs pair beautifully with cooling mint chutney or a simple yogurt dip. The recipe scales effortlessly for parties or meal prep, making it ideal for summer gatherings or weeknight dinners.
Whether you're grilling outdoors or using your oven, this method delivers foolproof results with minimal effort.
For an extra touch, try basting the skewers with a little honey during the last few minutes of grilling. This adds a subtle sweetness that complements the natural flavors of the sweet potatoes. The crispy celery crown not only looks impressive but also provides a satisfying contrast in every bite.

Sweet potatoes are the star here, so pick firm, dry ones—the kind that feel heavy for their size. Trader Joe's and Whole Foods usually carry the best varieties, but any orange-fleshed sweet potato works. Cut them into 1.5-inch cubes, and don't skip peeling—it keeps the texture clean. For the celery, thick stalks create the best crispy crowns. Trim them into 2-inch sticks, and soak the skewers in water for at least 30 minutes to prevent burning. The smoked paprika? Penzeys has the best quality, but any good brand will do—just make sure it's labeled 'smoked' for that authentic flavor.
No smoked paprika? Substitute with a mix of regular paprika and a pinch of liquid smoke—it's a game-changer. Running low on celery? Use thick carrot sticks instead, but they won't crisp up quite the same. For the yogurt dip, Greek yogurt is ideal, but regular works too. If you're feeling fancy, add a sprinkle of everything bagel seasoning for extra crunch. And if you're grilling indoors, broil on high for 3-4 minutes to mimic the smoky flavor. The key is patience—let those sweet potatoes caramelize, but don't overcook or they'll turn mushy.
These kababs are best served fresh off the grill, but you can prep ahead. Store the skewers in the fridge for up to 2 days, but don't soak the celery or it'll get soggy. For the yogurt dip, mix everything together just before serving so it stays thick. Leftovers? Reheat in the oven at 375°F for 10 minutes—they taste even better the next day. Freezing isn't recommended, as the celery loses its crunch. If you're making these for a crowd, double the batch and grill in batches to keep the heat consistent.

The skewers hold everything together while you grill or roast, so you’re basically assembling a meal while scrolling through your phone.
- Smoky Sweet Magic: That smoked paprika? It’s the secret weapon. The sweet potatoes caramelize into something tender yet slightly crisp, while the celery adds a fresh crunch that balances the smoky depth.

I’ll be real: I’ve reheated these in the oven until crispy again, and they’re just as good the second time around. Zero waste, maximum flavor.
Step-by-step instructions for sweet potato kababs
Here's how to create perfectly balanced kababs with caramelized sweet potatoes and crispy celery crowns.
Prep and Marinate the Sweet Potatoes
Cut the 2 lbs sweet potatoes into 1-inch cubes, ensuring they're uniform in size for even cooking. Place them in a large bowl and toss with the 0.25 cup extra-virgin olive oil, 1 tbsp smoked paprika, 1 tsp salt, and 0.5 tsp black pepper. Mix well until every piece is coated in the marinade—this ensures maximum flavor penetration and crispy edges.
Let the marinated sweet potatoes sit at room temperature for 30 minutes while you prepare the celery. This brief resting period helps the flavors meld together and prevents the sweet potatoes from steaming when they hit the grill or skillet. The marinade should cling to the cubes like a thin, flavorful coating.
Assemble the Kababs with Celery Crowns
Soak the 8 wooden skewers in water for at least 30 minutes to prevent burning on the grill. Thread 2 pieces of marinated sweet potato onto each skewer, then add 1 thick-cut celery stick, cutting it at a slight angle so it forms a "crown" at the top. Add another 2 pieces of sweet potato, then repeat with another celery stick. This alternating pattern creates visual appeal and ensures even cooking.
Work quickly so the sweet potatoes don't sit too long before cooking. The celery should be positioned at both ends of each skewer—this helps create those beautiful crispy crowns while keeping the sweet potatoes tender. If any skewers feel wobbly, secure them with a small piece of kitchen twine to prevent them from falling apart on the grill.
Grill to Perfect Caramelization
Heat a grill or grill pan over medium-high heat until it's hot enough to sear the sweet potatoes without burning. Place the kababs on the grill and cook for 10-12 minutes, turning occasionally, until the sweet potatoes are tender when pierced with a fork and the celery crowns are golden brown and slightly charred. You'll know they're ready when the sweet potatoes pull apart easily but still hold their shape.
For extra flavor, brush the kababs with the 1 tbsp honey during the last 2 minutes of cooking. This creates a beautiful caramel glaze that enhances the natural sweetness of the sweet potatoes. Watch carefully—the honey burns quickly, so keep the heat moderate during this final step.
Serve with Fresh Mint Yogurt Dip
While the kababs are still hot, prepare the yogurt dip by combining the 0.5 cup plain yogurt with the 2 minced garlic cloves and 1 tbsp lemon juice. Stir well to create a smooth, tangy base. Then fold in the 0.25 cup chopped fresh mint leaves, reserving a few for garnish. The dip should be cool and creamy, providing a refreshing contrast to the warm, smoky kababs.
Serve the kababs immediately with the mint yogurt dip on the side. The combination of crispy celery crowns, caramelized sweet potatoes, and cool yogurt creates a perfect balance of textures and flavors. For extra presentation, sprinkle the reserved mint leaves over the top of the dip and arrange the kababs on a platter with the celery crowns facing outward.
Pro Tips For Making Sweet Potato Kabab
- SOAK SKEWERS 30 MINUTES: I learned this the hard way—skipping soak time means your sweet potatoes slide off mid-cook. Toss wooden skewers in warm water for at least 30 minutes (or overnight if you're really impatient) so they don’t char before the veggies even get warm.
- CUT POTATO IN HALF LENGTHWISE: Thick chunks take forever to cook through and burn on the outside. Slice sweet potatoes into ½-inch thick half-moons instead of random cubes—this guarantees even cooking and that perfect tender-crisp texture you actually want.
- BRUSH WITH OIL AFTER SEASONING: Dry paprika sticks like glue if you sprinkle it first. Toss skewered veggies in olive oil, then season with smoked paprika after—this makes the spice cling properly and gives you that smoky crust without clumping.
- GRILL INDIRECTLY FOR LAST 5 MINUTES: After 10–12 minutes of direct heat, move kababs to the cooler side of the grill (or cover with foil). This locks in moisture while finishing the edges—no more dry, rubbery sweet potatoes that taste like they were microwaved.
Make-ahead tips for this dish
Prep Ahead Strategy
Marinate the sweet potatoes up to 24 hours ahead of grilling—I like doing this the night before. Store the cubed sweet potatoes in an airtight container with the olive oil, smoked paprika, salt, and pepper.
The flavors deepen over time, and the potatoes stay firm for skewering. Just bring them to room temperature before assembling the kababs. 🧂
Celery Crown Prep
Trim and cut the celery sticks 1 day ahead and store them in a sealed container in the fridge. Keep them dry to maintain crispness—damp celery loses its crunch.
When ready to assemble, simply rinse and pat dry before threading onto the skewers. This step saves 15 minutes of prep time on the day of cooking.
Skewer Assembly
Assemble the kababs 1-2 hours before grilling and refrigerate them uncovered on a wire rack. This allows the celery crowns to dry slightly, ensuring they crisp up beautifully on the grill.
Place parchment paper underneath to catch any drips. The sweet potatoes will stay firm and won't overcook during this time. ✨
Grill Prep Shortcut
Preheat your grill or grill pan 15 minutes before cooking—this ensures consistent heat. For indoor grilling, use a cast-iron skillet on high heat. I like to preheat my grill while the kababs come to room temperature, so everything's ready at the same time.
This method guarantees perfect searing every time.
Make-Ahead Serving
Cook the kababs 1 day ahead if you're planning to serve them cold. Let them cool completely, then store in an airtight container. Reheat in a 400°F oven for 5 minutes before serving to restore crispiness. The flavors actually improve overnight as the spices meld together. Perfect for meal prep!
Dip Prep Timing
Make the yogurt dip 30 minutes before serving—it needs time to chill and develop its tangy flavor. Store it in a small container in the fridge, and it'll be perfectly cool when ready to serve.
The mint stays fresh longer if you add it just before serving, but you can mix it in up to 2 hours ahead if needed. 🍯

Frequently asked questions
Can I use regular potatoes instead of sweet potatoes?
While you can substitute regular potatoes, the flavor and texture won't be the same. Sweet potatoes have a natural sweetness and creamier texture that works perfectly for kababs. If you must use regular potatoes, try russet or Yukon gold—they hold up better on skewers, but they lack the caramelization potential of sweet potatoes. For best results, stick with sweet potatoes!
How do I prevent the celery crowns from burning before the sweet potatoes cook?
Start with medium-high heat and monitor closely. The celery crowns cook faster than the sweet potatoes, so remove the kababs when the celery is golden brown and the sweet potatoes are almost tender. Finish cooking them in a 375°F oven for 2-3 minutes to fully cook the sweet potatoes without over-browning the celery. This two-step method ensures perfect doneness!
What if I don't have a grill? Can I make these in the oven?
Preheat your oven to 425°F and place the kababs on a foil-lined baking sheet. Bake for 12-15 minutes, turning halfway through, until the sweet potatoes are tender and the celery crowns are crispy. For extra smokiness, place a metal tray with wood chips underneath the kababs during baking. The oven method works just as well for indoor cooking!
Can I make these kababs ahead of time?
Yes, but with a few adjustments. Assemble the kababs and refrigerate them uncovered for up to 2 hours before cooking to help the celery dry out. For make-ahead serving, cook the kababs completely, then store them in an airtight container. Reheat in a 375°F oven for 5 minutes to restore crispiness. The flavors actually improve overnight!
What's the best way to store leftover kababs?
Store cooked kababs in an airtight container in the fridge for up to 4 days. The sweet potatoes will soften slightly, but reheating in a 375°F oven for 5-7 minutes restores their texture. For longer storage, freeze the kababs (without the dip) for up to 1 month. Thaw overnight in the fridge before reheating. The celery may lose some crispness after freezing.
