Sweet potatoes are the star—organic or heirloom varieties have the best flavor and texture. Costco or Trader Joe's usually carry them year-round, but check the produce section for firm, heavy tubers. Smoked paprika is non-negotiable for that signature Taco Bell taste—Penzeys or Gourmet Garage have great options. The celery should be crisp and pale green; yellowing means it's past its prime. I always buy extra because I use it for both the crown and garnish. For the brown sugar, Domino or C&H are reliable brands that won't clump in your seasoning mix.
No smoked paprika? Regular paprika plus a pinch of liquid smoke works in a pinch. The celery crown can be baked instead of fried—toss slices in olive oil, salt, and pepper, then bake at 400°F for 10-12 minutes. For the sweet potatoes, if you can't find organic, regular sweet potatoes work fine—just peel them well. The flour for the celery crown can be swapped for cornstarch if you're gluten-free. And if you're worried about the celery turning brown, keep it submerged in cold water until ready to use—it'll stay crisp and fresh.
Sweet potatoes keep for 2-3 weeks in a cool, dark place, but they'll last longer in the fridge. Celery stays fresh for 1 week wrapped in damp paper towels. The seasoning mix (brown sugar, paprika, cinnamon) can be pre-mixed and stored in an airtight container for 2 weeks. I always make extra seasoning—it's perfect for roasted sweet potatoes or even sprinkling on oatmeal. The fried celery crown is best served immediately, but you can reheat it in a dry skillet for 1-2 minutes if needed.

Step-by-step instructions for sweet potato thang copycat recipe
Here's how to recreate that perfect balance of crispy, smoky sweet potatoes with a golden celery crown.
Prepare and Roast the Sweet Potatoes
Preheat your oven to 375°F. Peel and cut the 2 whole large sweet potatoes into 1-inch cubes. Toss them in a large bowl with 2 tablespoons olive oil, 0.5 cup packed brown sugar, 1 tablespoon smoked paprika, 1 teaspoon ground cinnamon, 1 teaspoon salt, and 0.5 teaspoon black pepper. Mix until every cube is evenly coated and glistening.
Spread the sweet potatoes in a single layer on a parchment-lined baking sheet, leaving space between each piece. This ensures even browning and crispiness. Roast for 35-40 minutes, stirring halfway through, until the edges are deep golden brown and the cubes are tender when pierced with a fork. The sweet potatoes should caramelize beautifully, developing that signature smoky-sweet flavor that makes this dish so addictive.
Create the Crispy Celery Crown
While the sweet potatoes roast, prepare the celery crown. Thinly slice the 2 whole celery stalks into ¼-inch thick rounds. In a shallow bowl, whisk together the 1 whole large egg and 0.25 cup all-purpose flour until smooth. Dip each celery round into the egg mixture, letting any excess drip off, then carefully place on a wire rack.
Heat 0.5 cup vegetable oil in a small skillet over medium heat until it shimmers but doesn't smoke. Fry the celery rounds in batches for 1-2 minutes per side until golden brown and crispy. Drain on paper towels and sprinkle immediately with 2 tablespoons granulated sugar while still warm. The sugar will caramelize slightly, adding a sweet crunch that perfectly complements the sweet potatoes.
Assemble and Serve Warm
Once the sweet potatoes are perfectly roasted, transfer them to a serving dish. Arrange the crispy celery crowns on top in a circular pattern, creating that iconic "crown" look. The contrast between the warm, caramelized sweet potatoes and the crispy, sugary celery is what makes this dish so irresistible.
Serve immediately while everything is warm and crispy. The sweet potatoes should be tender with a crispy exterior, and the celery crown should hold its shape while adding a delightful crunch. For extra flair, garnish with an additional sprinkle of smoked paprika or a dusting of granulated sugar right before serving. This dish is best enjoyed fresh out of the oven when all the textures and flavors are at their peak!
Pro Tips For Making Sweet Potato Thang Copycat
- CUT POTATOES EVENLY: Use a mandoline or sharp knife to slice them into ¼-inch thick rounds—any thicker and they’ll stay undercooked inside while burning outside. I learned this the hard way after pulling out gummy centers from uneven cuts.
- SALT THE WATER LIKE THE SEA: Toss your sweet potatoes in 1 tablespoon of salt per gallon of water before boiling. The starch releases faster, and the flavor gets deeper—no need to add extra salt later. (Yes, even if you’re impatient like me, wait for the water to fully absorb the salt first.)
- DON’T SKIP THE PARBOIL: Boil the potatoes for 8-10 minutes until they’re fork-tender but not falling apart—this guarantees they’ll caramelize evenly later. I used to skip this, and the final texture always came out either mushy or dry.
- USE LIGHT BROWN SUGAR: Light brown sugar dissolves better and crisps up nicer than dark—mix it with the spices before tossing with the potatoes so it coats evenly. (Your future self will thank you when you’re not scraping burnt sugar off the pan.)
Regional styles of sweet potato thang copycat
Texas-Style Taco Bell
The original Sweet Potato Thang was born in Texas, where Taco Bell first introduced it as a limited-time offering. The Texas version leans into bold, smoky flavors with extra cinnamon and a touch of cayenne for heat.
I like to add ½ teaspoon cayenne pepper to the seasoning mix for that signature kick. Serve with crunchy taco shells and spicy ranch sauce for the full Texas experience. 🌶️
Southern Comfort Twist
In the Southern U.S., this dish gets a buttery, maple-glazed variation. After roasting the sweet potatoes, I drizzle them with 1 tablespoon maple syrup and 1 tablespoon melted butter, then broil for 2-3 minutes to caramelize.
The celery crown stays the same, but the sweet potatoes become even richer and more decadent. Pair with fried chicken tenders for a true Southern feast.
West Coast Crunch
Out West, the focus is on extra crispiness—both the sweet potatoes and celery crown get an upgrade. I air-fry the sweet potatoes at 400°F for 20 minutes before finishing in the oven to lock in crunch.
The celery crown is double-dipped in egg and flour for an ultra-crispy texture. Top with chopped pecans for a nutty crunch that balances the sweetness. Perfect with California-style burritos or as a standalone snack. 🥜
Midwest Sweet Heat
The Midwest version keeps the smoky-sweet profile but adds a caramelized onion topping. Sauté ½ cup diced onion in 1 tablespoon butter until golden, then sprinkle over the roasted sweet potatoes before adding the celery crown.
The onions add a deep, savory note that complements the sweetness. Serve with cheesy pulled pork for a hearty meal that’s pure comfort food. 🧀
Air Fryer Hack
For a quick, crispy version anywhere, use an air fryer instead of the oven. Toss the sweet potato cubes with seasoning and air-fry at 400°F for 12-15 minutes, shaking the basket every 5 minutes.
The celery crown can also be air-fried at 375°F for 3-4 minutes until golden. This method cuts prep time by half while keeping all the flavor. Ideal for busy weeknights! ⚡

Frequently asked questions
Can I make this recipe without an oven?
Use an air fryer instead for the sweet potatoes. Toss the cubes with seasoning and air-fry at 400°F for 12-15 minutes, shaking every 5 minutes for even crispiness. The celery crown can also be air-fried at 375°F for 3-4 minutes until golden. This method works perfectly and cuts prep time by half!
Why does my celery crown turn out soggy?
Soggy celery crowns usually happen from overcrowding or not draining properly after frying. Fry in small batches and ensure the oil is at medium heat—it should shimmer but not smoke. Drain on paper towels and sprinkle with sugar immediately while warm to lock in crispiness. For extra crunch, double-dip in egg and flour before frying.
What’s the best way to store leftovers?
Store the sweet potatoes and celery crown separately. Keep the sweet potatoes in an airtight container for up to 3 days, and reheat in a 350°F oven for 5-10 minutes until crispy again. The celery crown is best served fresh but can be reheated in a dry skillet for 1-2 minutes if needed. Freezing isn’t recommended for the celery crown—it loses its crunch.
Can I use regular potatoes instead of sweet potatoes?
While you can use regular potatoes, the flavor and texture won’t be the same. Sweet potatoes provide that natural sweetness and creamy interior that’s key to the dish. If you’re set on using regular potatoes, add 1 extra tablespoon of brown sugar and ½ teaspoon more cinnamon to compensate for the lack of sweetness. Russet potatoes work best for a crispier texture.
What’s the secret to getting that perfect smoky flavor?
The smoky flavor comes from smoked paprika and proper roasting. Don’t skip the smoked paprika—it’s non-negotiable for that signature Taco Bell taste. For extra depth, add ¼ teaspoon of liquid smoke to the seasoning mix. Also, roast the sweet potatoes until they’re deep golden brown—this caramelization enhances the smoky notes.
