Ingredients for sweet potato jojo's

Sweet potatoes, celery, and spices—just like Jojo's, but made at home with crispy perfection.

The sweet potatoes make or break this. Orange-fleshed, firm varieties work best—avoid the mealy ones. Trader Joe's or Whole Foods usually carry the perfect ones. For the celery, look for thick stalks with no leafy tops (they dry out fast). I always buy extra—half gets made into crowns, the rest goes into the mash for extra flavor. The key is cutting the sweet potatoes into even sticks (about 1/4-inch thick) so they crisp uniformly. If you're feeling fancy, Costco sells pre-cut sweet potato fries—just toss them straight in the seasoning.

No smoked paprika? Regular paprika plus a pinch of liquid smoke works in a pinch. The celery crowns can be prepped ahead—just store them in a sealed container with a damp paper towel to keep them crisp. For the mash, Greek yogurt instead of cream cuts calories but loses that signature richness. The butter? European-style or cultured butter melts smoother, but regular works fine. Pro tip: Microwave the butter 40 seconds to just melt it before mixing—no waiting for the stove.

Sweet potato fries and crowns keep crisp for 2 days if stored in an airtight container, but honestly they taste best fresh. The mash reheats beautifully—just add a splash of milk or cream to loosen it up. Freeze portions for up to 3 months if you're meal prepping. I always make a double batch of mash because it disappears fast. For leftovers, re-crisp the fries in the oven at 400°F for 5-10 minutes—they'll taste like they just came out of the diner.

Step-by-step instructions for sweet potato Jojo's recipe

Here's how to nail Jojo's iconic combo—crispy celery crowns and velvety sweet potato mash.

Preheat your oven to 400°F. Peel and cut the 2 lbs sweet potatoes into 1-inch chunks, then toss them in a large bowl with 2 tbsp vegetable oil, 1 tbsp granulated sugar, 1.5 tsp salt, 0.5 tsp garlic powder, and 0.5 tsp onion powder. Spread them in a single layer on two rimmed baking sheets.

Roast for 25-30 minutes until the edges are golden brown and a knife slides in easily with just slight resistance. You want them soft but not falling apart—this ensures your mash will be smooth and creamy. Give them a gentle stir halfway through if they're crowded.

While the sweet potatoes roast, trim the 2 whole celery stalks by cutting off the leafy tops and bottoms. Cut each stalk lengthwise into ¼-inch thick strips, then slice those strips crosswise into ½-inch pieces. This creates those signature celery "crowns" that get beautifully crispy.

Toss the celery pieces in a small bowl with 2 tbsp all-purpose flour, 0.5 tsp paprika, and 0.5 tsp ground black pepper. This coating will give them that perfect crunch. Spread them on a separate baking sheet and roast at 400°F for 15-20 minutes until golden brown and crispy. Flip them halfway for even browning.

Once the sweet potatoes are tender, drain any excess liquid from the baking sheet and transfer the potatoes to a large bowl. Add the 0.5 cup cold unsalted butter and mash with a potato masher or fork until mostly smooth—just a few lumps are fine. The butter adds richness that makes this mash extra velvety.

Stir in the 0.25 cup heavy whipping cream and mix until fully incorporated. The cream should blend seamlessly, creating a luxurious texture. Taste and adjust seasoning if needed—you might want to add a pinch more salt or a touch of pepper to balance the sweetness.

Serve the sweet potato mash in a bowl and top with the crispy celery crowns. The contrast of creamy mash and crunchy celery is what makes this dish so special. For extra flair, sprinkle with additional paprika or a drizzle of melted butter if you're feeling fancy.

Here's the thing—this dish shines when served immediately while the celery crowns are still crispy. The sweet potatoes will stay warm for a while, but the celery loses its crunch as it cools. Enjoy with a side of honey butter or a simple green salad for the full Jojo's experience!

Flavor customization for this dish

Sweet & Smoky Twist

For a deeper flavor profile, add ½ tsp cinnamon and ¼ tsp cayenne pepper to the sweet potato seasoning. The cinnamon enhances the natural sweetness while the cayenne adds a subtle heat that mimics Jojo's signature spice blend.

I find this works especially well with orange-fleshed sweet potatoes—their natural sugars caramelize beautifully with these spices. 🌶️

Extra Crunchy Celery

Want even crispier celery crowns? Toss them in 1 tbsp cornstarch before baking instead of flour. The cornstarch creates a lighter, crunchier coating that stays crisp longer. I like to bake them at 425°F for the last 5 minutes to intensify the browning. Serve immediately for maximum crunch.

Creamy Garlic Mash

Infuse the mash with garlic flavor by sautéing 2 minced garlic cloves in 1 tbsp butter until golden before adding to the sweet potatoes. This adds a subtle depth that pairs perfectly with the celery crowns.

For extra richness, stir in 1 oz cream cheese at the end—it blends seamlessly and creates a restaurant-quality texture.

Spicy Honey Glaze

Drizzle the assembled dish with a mix of 1 tbsp honey and ½ tsp chili powder before serving. The sweetness of the honey balances the earthy sweet potatoes while the chili powder adds a smoky kick.

I like to warm this glaze slightly before drizzling to enhance its flavor. This works especially well if you're serving the dish as a main course.

Herbed Butter Mash

For a fresh twist, mix 1 tbsp chopped fresh rosemary or thyme into the butter before adding it to the sweet potatoes. The herbs add an aromatic brightness that cuts through the richness.

I recommend using dried herbs** if you're making this ahead—they'll keep better. This variation works beautifully with the celery crowns and adds a sophisticated touch.
