Grilled White Sweet Potato Recipe: Caramelized Edges and Creamy Centers

White sweet potatoes take on new dimension when kissed by fire, developing caramelized edges while maintaining their naturally creamy centers. This method transforms their subtle sweetness into something extraordinary.

I discovered this technique during a coastal cookout, using simple grilling to enhance the potatoes’ natural flavors without masking them. The direct heat creates a crisp exterior while the inside stays tender and moist.

The result is a dish that’s both rustic and refined—sweet, smoky, and satisfying. The contrast between the charred exterior and soft interior makes every bite memorable.

Perfect as a side or light main, these potatoes prove that sometimes the simplest preparations yield the most impressive results.

The white sweet potatoes are key here—look for firm, unblemished skins and uniform size (about 8 oz each) for even cooking. Whole Foods or Trader Joe’s often carry them year-round, but most supermarkets stock them seasonally. The olive oil should be high-quality extra-virgin; its fruity notes complement the potatoes’ natural sweetness beautifully.

No white sweet potatoes? Regular sweet potatoes or yams work in a pinch, but their flavor is more assertive. Skip the cumin if you prefer a purer taste, or swap smoked paprika for chipotle powder for extra heat. The lime zest is non-negotiable—it brightens the smoky depth. Fresh cilantro haters can use flat-leaf parsley instead.

Prep the potatoes just before grilling to prevent browning. Leftovers keep in the fridge for 3-4 days—reheat in a skillet to revive the crisp edges. Not ideal for freezing, as the texture softens too much. Serve warm for the best contrast between charred exterior and creamy centers.

Step-by-Step Instructions for Grilled White Sweet Potatoes

This method ensures even cooking with the perfect balance of smoky exterior and tender interior.

Step 1: Prepare and Season the Sweet Potatoes

Begin by scrubbing the 2 lb white sweet potatoes thoroughly under cold water to remove any dirt, then pat them completely dry. I cut them into 1-inch thick rounds—this thickness ensures they cook through without burning on the outside.

In a large bowl, toss the sweet potato rounds with 2 tbsp extra-virgin olive oil, then sprinkle evenly with the 1.5 tsp kosher salt, 0.5 tsp freshly ground black pepper, 1 tsp smoked paprika, 1 tsp garlic powder, and 0.5 tsp ground cumin. Use your hands to coat every piece thoroughly, pressing the spices into the surface so they adhere well during grilling.

Step 2: Preheat and Arrange the Grill

Preheat your grill to medium-high heat (about 400°F). A properly heated grill is essential for achieving those caramelized edges while ensuring the centers cook to creamy perfection. Clean the grates thoroughly with a grill brush to prevent sticking.

If using a charcoal grill, bank the coals to one side to create both direct and indirect heat zones. For a gas grill, preheat all burners, then reduce one side to medium-low for indirect cooking. This setup allows you to sear the potatoes first, then move them to finish cooking through without charring.

Step 3: Grill to Caramelized Perfection

Arrange the seasoned sweet potato rounds on the grill over direct heat. Cook undisturbed for 4-5 minutes per side until you see deep grill marks and the edges begin to caramelize. Resist the urge to move them—letting them sit ensures proper searing and prevents sticking.

Once both sides are marked, move the potatoes to the indirect heat zone (or reduce the gas grill to medium heat). Close the lid and let them cook for an additional 8-10 minutes, turning occasionally, until they’re tender when pierced with a fork and the centers are creamy. If some pieces finish early, transfer them to a serving plate to keep warm.

Step 4: Finish with Bright, Fresh Flavors

Transfer the grilled sweet potatoes to a serving platter and drizzle with the remaining 1 tbsp extra-virgin olive oil. Zest the lime directly over the potatoes, then cut it in half and squeeze the juice evenly across the top. This bright acidity cuts through the richness and enhances the smoky flavors.

Sprinkle with the 0.25 cup chopped fresh cilantro and, if desired, a pinch of 0.25 tsp red pepper flakes for a subtle kick. Serve immediately while the edges are still crisp and the centers are at their creamiest. The contrast of textures and flavors is what makes this dish exceptional.

Essential Equipment for grilled white sweet potato

Grill Essentials

For perfect grill marks and even cooking, I swear by my Weber Genesis II gas grill. Its consistent heat distribution at 400°F gives those beautiful char lines while keeping the centers tender. A grill thermometer is non-negotiable for precision.

Charcoal Option

For that authentic smoky flavor, my Kamado Joe ceramic grill can’t be beat. Bank the coals to create direct and indirect heat zones, and use hickory lumps for a subtle sweetness that complements the potatoes. The thick walls maintain steady heat.

Grill Tools

Invest in a long-handled grill brush with brass bristles for safe, effective cleaning. I also keep a perforated grill pan handy for smaller potato pieces that might fall through the grates. These tools make grilling easier and safer.

Heat Management

A dual-probe thermometer like my ThermoWorks Smoke lets me monitor both grill and potato temperatures. This ensures I hit that sweet spot of 400°F for searing while tracking the internal doneness. 🌡️

Serving Gear

Use a large stainless steel platter for serving—it retains heat beautifully. I also keep a microplane nearby for zesting the lime directly over the potatoes. These small touches elevate the presentation.

For outdoor dining, a grill-side table keeps all your tools and seasonings organized and within reach. 🔥
