Grilled Sweet Potato Slices Recipe: Caramelized Edges with Honey Glaze

Fire up your grill for a side dish that steals the show with its natural sweetness and smoky depth. This method transforms humble sweet potatoes into caramelized, tender slices with a sticky honey finish.

The key is cutting uniform slices and grilling over medium heat until golden brown and tender. A light brush of oil prevents sticking while allowing the natural sugars to develop those coveted charred edges.

What emerges from the grill are perfectly cooked sweet potatoes with caramelized surfaces and a subtle smokiness that complements the sweet honey glaze. The contrast between tender centers and crispy edges is irresistible.

Serve these alongside grilled proteins or as a standalone vegetarian option. The honey glaze adds just the right amount of sweetness to balance the earthy flavor of the potatoes.

The sweet potatoes should be firm and vibrant orange—avoid any with soft spots or sprouting. Organic is ideal (the skin stays on longer during prep), but conventional works fine. I grab mine from Whole Foods or the local farmers market. Uniform thickness is key—use a mandoline for perfect 1/2-inch rounds if you have one (or just a sharp knife and steady hand).

No honey? Maple syrup or agave gives the same sticky finish with a slightly different flavor. Swap smoked paprika for regular if you prefer milder spice. Out of fresh rosemary? Dried thyme or sage at half the amount works well. The cinnamon can be skipped if you’re not a fan—it adds warmth but isn’t essential to the dish.

Prep the potatoes just before grilling to prevent browning. Leftovers keep in the fridge for 3-4 days—reheat in a skillet or oven for best texture. The honey glaze can be made ahead and stored at room temperature for 1 week.

Step-by-Step Instructions for Grilled Sweet Potato Slices

Here’s the method I use to achieve perfectly caramelized edges and a sweet, smoky finish every time.

Step 1: Prepare and Season the Sweet Potato Slices

Peel the 2 lb Sweet Potatoes and cut them into ½-inch thick rounds. Uniform thickness ensures even cooking and prevents some pieces from burning while others stay undercooked.

In a large bowl, toss the sweet potato slices with 1 tbsp Olive Oil, 1 tsp Salt, 0.5 tsp Black Pepper, 0.5 tsp Garlic Powder, 0.25 tsp Smoked Paprika, and 0.5 tsp Ground Cinnamon. This spice blend creates a warm, aromatic foundation that complements the natural sweetness of the potatoes.

Let the slices sit for 10 minutes to absorb the seasoning. This rest period also helps the sweet potatoes start releasing their natural sugars, which will caramelize beautifully on the grill.

Step 2: Preheat the Grill and Prepare the Glaze

Preheat your grill to medium-high heat (about 400°F). A properly heated grill ensures the sweet potatoes get those coveted grill marks without sticking. Clean the grates thoroughly with a grill brush to prevent the slices from tearing when you flip them.

While the grill heats, whisk together the remaining 2 tbsp Olive Oil, 0.25 cup Honey, 2 tsp Fresh Rosemary, and 1 tbsp Lemon Juice in a small bowl. The rosemary adds an earthy note, while the lemon juice balances the sweetness of the honey with a subtle brightness.

Step 3: Grill the Sweet Potatoes to Caramelized Perfection

Arrange the seasoned sweet potato slices on the grill in a single layer, leaving a little space between each piece for even cooking. Close the lid and cook for 5-6 minutes until the undersides develop distinct grill marks and start to caramelize.

Carefully flip each slice using a thin, flexible spatula—they’ll be tender but should hold together if you let them cook undisturbed. Brush the top sides generously with half the honey glaze. Close the lid and cook for another 4-5 minutes until the slices are tender and the glaze begins to bubble and caramelize.

Step 4: Finish with Glaze and Rest Briefly

Flip the slices one final time and brush with the remaining honey glaze. Cook for an additional 2-3 minutes to set the glaze and deepen the caramelization. The sweet potatoes are done when they’re fork-tender and have deep, golden-brown edges.

Transfer the grilled sweet potato slices to a serving platter. Let them rest for 2-3 minutes before serving. This brief rest allows the glaze to thicken slightly and the flavors to meld together.

The finished slices should have a perfect balance of smoky, sweet, and savory notes with a slightly crisp exterior and a creamy, tender interior.

Dietary Considerations for This grilled sweet potato slices

Vegan Adaptation

This dish is naturally vegan as written, making it perfect for plant-based diets. Simply swap the honey for maple syrup or agave to keep it strictly vegan while maintaining that sticky, caramelized finish. I often use Grade B maple syrup for its deeper flavor. 🌱

Gluten-Free Friendly

All ingredients here are inherently gluten-free, so no modifications are needed. Just double-check your spice blends if using pre-mixed versions, as some brands add anti-caking agents that contain gluten. I always source my spices from specialty shops to avoid this issue.

Nut Allergy Safe

This recipe contains no nuts or nut-derived ingredients. The only potential concern would be cross-contamination in your honey or spices. For complete safety, use certified nut-free facilities products when available.

Low Glycemic Option

To reduce the glycemic impact, cut the honey glaze by half and add 1 tsp apple cider vinegar to balance sweetness. This small tweak helps moderate blood sugar response while keeping the flavor profile intact. I learned this trick from a nutritionist friend at a local BBQ competition.

Sodium Control

For those watching sodium intake, reduce the salt to ½ tsp and use a salt-free seasoning blend. The smoked paprika and garlic powder still provide plenty of flavor. Herbs like fresh rosemary add depth without additional sodium.

Diabetic Considerations

Sweet potatoes have a lower glycemic index than regular potatoes, but portion control is key. Stick to ½ cup serving and pair with protein to further slow glucose absorption. The cinnamon in this recipe may help regulate blood sugar naturally. 💡
