Above them are five small bowls arranged in a loose shape, four made of dark wood containing different seasonings: one with white salt crystals, one with light brown powder, one with coarse black pepper, and one with finely ground black pepper. In the center, there is a small clear glass pitcher filled with golden oil. The overall setting is simple and natural, with the rough textures of the sweet potatoes contrasting the smooth bowls and glass container. photo taken with an iphone --ar 4:5 --v 7

This recipe calls for simple, wholesome ingredients that work together beautifully to create both flavor and color in this grilled dish.

4 sweet potatoes, cut into 1/2″ thick slices: I find slicing them evenly is key for consistent cooking and perfect texture.
1/4 cup olive oil: Adds richness and helps the seasoning stick, while also encouraging caramelization on the grill.
1 teaspoon garlic powder: Gives a subtle savory depth without overpowering the natural sweetness.
1 teaspoon kosher salt: Essential for enhancing all the natural flavors of the sweet potatoes.
1/2 teaspoon coarse ground black pepper: Adds a gentle heat that complements the sweetness beautifully.
1/2 teaspoon rubbed sage: Brings an earthy, herby note that elevates the entire dish.

Directions

Step 1: Preheat your grill to 350 degrees Fahrenheit. This moderate temperature is perfect for cooking the sweet potatoes evenly without burning them.

Step 2: In a large bowl, combine the olive oil, garlic powder, kosher salt, coarse ground black pepper, and rubbed sage. Mix everything thoroughly so that the seasonings are well distributed in the oil.

Step 3: Add your sweet potato slices to the bowl and toss them gently to coat each slice thoroughly with the seasoning mixture. Make sure every slice is covered; this helps build layers of flavor during grilling.

Step 4: Line a large baking sheet with parchment paper and arrange the sweet potato slices on it skin side down. This helps protect the skin and allows the flesh to cook evenly.

Step 5: Place the baking sheet on the grill and cook for 6 to 8 minutes. The potatoes will start to soften during this stage and absorb that wonderful smoky flavor.

Step 6: Flip each slice carefully and cook for another 3 to 4 minutes. This ensures both sides are tender and getting some color.

Step 7: Remove the slices from the baking sheet, brush them with any remaining olive oil mixture in the bowl, then place directly onto the grill grates.

Step 8: Grill the potatoes for 2 minutes on each side or until you see beautiful grill marks and a slight crisp develops. This final step adds fantastic texture and visual appeal.

Servings and Timing

This Grilled Sweet Potatoes Recipe yields about 6 servings, making it a perfect side for a small family dinner or a backyard barbecue gathering. The prep time is delightfully short at just 10 minutes, followed by about 20 minutes of cooking. In total, you’re looking at roughly 30 minutes from start to finish, including the resting time needed to get those perfect grill marks and flavors to develop fully.

How to Serve This Grilled Sweet Potatoes Recipe

Several round slices of grilled sweet potatoes with bright orange centers and charred dark brown edges are placed directly on black grill grates. The slices vary slightly in size, and some have more prominent dark grill marks while others show a more even orange surface with specks of black seasoning.

When I serve grilled sweet potatoes, I love pairing them with something fresh and bright to balance their natural sweetness. A crisp green salad with a tangy vinaigrette or some grilled veggies like zucchini and bell peppers make fantastic companions. For a heartier meal, these potatoes are incredible alongside grilled chicken, pork chops, or even a juicy burger.

Presentation-wise, I like to stack them loosely on a rustic serving platter and finish with a sprinkle of fresh herbs like parsley or cilantro for a pop of green. A drizzle of a tangy yogurt sauce or a dash of smoked paprika on top adds an extra layer of flavor and color that always delights guests. Whether plated for a casual family dinner or a festive holiday meal, those grill marks and vibrant colors really steal the show.

As for drinks, I find that a chilled crisp white wine pairs beautifully – think Sauvignon Blanc or a light Chardonnay. For non-alcoholic options, sparkling water with a twist of lime or a fruity iced tea makes the meal feel special. These potatoes taste best served warm right off the grill, but they’re still delicious at room temperature if you’re setting up a buffet or picnic. Portion-wise, I usually recommend two to three slices per person depending on appetite and what else you’re serving.

Variations

One of my favorite things about this Grilled Sweet Potatoes Recipe is how adaptable it is. If you want to switch things up, try swapping the sage for rosemary or thyme for a different herbal dimension. For a bit of heat, add a sprinkle of smoked chili powder or cayenne. If you’re vegan or gluten-free, this recipe works perfectly as is since it’s naturally free of gluten and lends itself so well to clean, plant-based eating.

If you’re short on grill time or the weather isn’t cooperating, I sometimes roast the sweet potatoes in the oven at 425 degrees Fahrenheit for about 20 minutes, flipping halfway through. While you won’t get those grill marks, you still get lovely caramelization and flavor.

For a sweeter take, try brushing the slices with a honey-lime glaze during the last minutes on the grill or sprinkling with cinnamon and a pinch of brown sugar before cooking. These variations keep the recipe exciting and tailored to your personal taste preferences.

Storage and Reheating

Storing Leftovers

Leftover grilled sweet potatoes store wonderfully in an airtight container in the refrigerator. I recommend using glass or BPA-free plastic containers to keep them fresh and avoid any unwanted odors. They will keep well for 3 to 4 days, making them perfect for quick lunches or meal prep throughout the week.

Freezing

You can freeze grilled sweet potatoes if you want to keep them longer. Lay the slices out on a parchment-lined baking sheet in a single layer and freeze until solid, about 1 to 2 hours, before transferring them to a freezer-safe bag or container. This method helps keep them from sticking together. Frozen grilled sweet potatoes will maintain the best quality for up to 2 months.

Reheating

When reheating, I recommend using an oven or toaster oven set to 350 degrees Fahrenheit to help restore that slightly crisp exterior without drying out the flesh. Heat for about 10 minutes or until warmed through. Avoid microwaving if you want to retain the texture since it can make the potatoes mushy. A quick re-grill on the stovetop or grill pan also works great to bring back some of that fresh-off-the-grill magic.

FAQs

Can I use regular potatoes instead of sweet potatoes?

Absolutely! Regular potatoes work well with this seasoning and grill method. Keep in mind that they might take a bit longer to cook depending on their thickness. I recommend parboiling regular potatoes first to ensure they cook evenly on the grill.

Do I need to peel the sweet potatoes before grilling?

I prefer to leave the skin on because it adds texture and helps hold the slices together while grilling. Plus, the skin is packed with nutrients and becomes tender once grilled. Just be sure to wash the potatoes well before slicing.

How do I know when the sweet potatoes are done grilling?

You want the sweet potatoes to be tender enough to pierce easily with a fork but still hold their shape. They should have nice grill marks and a slightly crispy exterior after the final grilling steps. Generally, the total time of about 15 minutes on the grill in stages should do the trick.

Can I prepare these grilled sweet potatoes ahead of time?

Yes! You can slice and season the potatoes a few hours ahead and keep them refrigerated until you’re ready to grill. This makes meal prep super convenient. Just be sure to bring them to room temperature before placing them on the grill for even cooking.

What if I don’t have a grill? Can I make this indoors?

Definitely. You can use a grill pan on the stovetop or bake the seasoned sweet potato slices in the oven. For grill marks, a cast-iron grill pan works best. Just follow similar cooking times and keep an eye on them so they don’t burn.

Conclusion

I hope you give this Grilled Sweet Potatoes Recipe a try soon, because it’s one of those simple dishes that brings so much joy to the table. The smoky, sweet flavors combined with its easy preparation make it a recipe I keep coming back to season after season. Whether you’re feeding family, impressing guests, or just treating yourself, these grilled sweet potatoes are always a hit that I’m sure you’ll love as much as I do.
