Grilled Sweet Potato Chips Recipe: Crispy Edges With Caramelized Sweetness

My pitmaster training taught me that grilling isn’t just for meat—these sweet potato chips prove it. This method delivers crispy edges with caramelized sweetness that you just can’t achieve in the oven.

The key is slicing the potatoes thin and even, then grilling them over direct heat until they develop those perfect charred spots. A light brush of oil prevents sticking while enhancing the natural flavors.

What you get is a dish with shatteringly crispy texture and deep, smoky-sweet notes that complement any meal. The grill imparts a unique char that elevates the humble sweet potato to something extraordinary.

Serve them as a snack, side dish, or even a light dessert. This technique works every time.

Ingredients for Grilled Sweet Potato Chips

Sweet potatoes, a few spices, and oil are all you need for these smoky grilled chips.

The sweet potatoes are key here. Look for firm ones with vibrant orange flesh—avoid any with soft spots or bruises. Whole Foods or Trader Joe’s usually have the best selection. I prefer organic when possible (fewer pesticides), but conventional works just fine. The oil matters too—extra-virgin olive oil adds depth that neutral oils can’t match.

No smoked paprika? Regular paprika plus a pinch of liquid smoke gets you close. Fresh garlic instead of powder? Mince 2 cloves and toss with the potatoes before grilling. Want more heat? Double the cayenne. The rosemary is totally optional but adds a nice piney note if you’ve got fresh on hand.

Slice the potatoes just before grilling to prevent browning. Leftovers? Reheat in a dry skillet to revive crispiness. Best eaten the same day, but they’ll keep in the fridge for 2 days (though they lose that shatter).

Step-by-Step Instructions for Grilled Sweet Potato Chips

Here’s my proven method for achieving perfectly crispy edges with caramelized sweetness every time.

Step 1: Slice and Prep the Sweet Potatoes

Start by scrubbing the 2 lb Sweet Potatoes clean under cold water, then slice them into ⅛-inch thick rounds using a sharp knife or mandoline. I like to leave the skin on for extra texture and nutrients, but peel them if you prefer a smoother chip.

As you slice, place the rounds in a large bowl of cold water to prevent browning. Once all sweet potatoes are sliced, drain and pat them completely dry with a clean kitchen towel. Any moisture left on the surface will prevent crispiness, so take your time with this step.

Step 2: Season Generously for Maximum Flavor

In a large bowl, toss the dried sweet potato slices with the 2 tbsp Olive Oil, ensuring each piece is evenly coated. Then sprinkle with 1 tsp Sea Salt, 0.5 tsp Black Pepper, 0.5 tsp Smoked Paprika, 0.5 tsp Garlic Powder, 0.25 tsp Ground Cumin, and 0.125 tsp Cayenne Pepper.

Use your hands to gently toss everything together, making sure the spices are distributed evenly. The smoked paprika adds a subtle smokiness, while the cumin and cayenne bring warmth and a hint of heat. Don’t skip the oil—it helps the seasoning stick and promotes even browning.

Step 3: Grill Over Indirect Heat

Preheat your grill to medium-high heat (around 375-400°F). Once hot, clean the grates thoroughly with a grill brush to prevent sticking. Reduce the heat to medium and arrange the sweet potato slices in a single layer on the grill, leaving a little space between each piece for even cooking.

Cook for 10-12 minutes per side, flipping once, until the edges are crispy and golden brown and the centers are tender with visible grill marks. Watch closely—the natural sugars in the sweet potatoes can cause them to burn if left unattended.

Step 4: Garnish and Serve Immediately

Transfer the grilled sweet potato chips to a serving platter while they’re still hot. Sprinkle with the 1 tbsp Fresh Rosemary for a bright, herbal finish. The rosemary pairs beautifully with the smoky, spiced flavors.

Serve right away while the chips are at their crispiest. They’re best enjoyed fresh off the grill, but if you need to hold them for a few minutes, keep them in a single layer on a wire rack to maintain their texture. The contrast of crispy edges and soft, caramelized centers makes these irresistible.

Pro Cooking Tips for This Recipe

Slice Evenly

Use a mandoline slicer for consistent ⅛-inch thick rounds—this ensures even cooking and crispiness. I learned this the hard way after too many uneven batches. A sharp chef’s knife works too, but takes more focus.

Dry Thoroughly

Pat the slices completely dry with a clean towel after soaking. Any moisture creates steam, which means soggy chips instead of crispy ones. This step is non-negotiable for that perfect texture.

Prevent Sticking

Brush the grill grates with olive oil just before adding the sweet potatoes. Even with oil in the seasoning, this extra step prevents sticking. I use tongs and a folded paper towel for safety.

Watch the Heat

Maintain medium heat (around 375°F) and flip after 5-6 minutes. The sugars caramelize fast, so keep an eye on those edges. A grill thermometer helps maintain consistency. 🔥

Space Matters

Arrange slices in a single layer with ½ inch between each. Crowding causes steaming and uneven cooking. Work in batches if needed—it’s worth the extra time.

Serve Smart

Transfer to a wire rack instead of a plate to keep crispy. The airflow prevents the bottoms from getting soggy. These are best eaten within 30 minutes of grilling. 💡
