Ingredients

  • Sweet Potatoes: This recipe prepared four medium to large sweet potatoes. When you’re picking out the potatoes, look for ones with fairly smooth skin and firm texture. Make sure to avoid any with soft spots or dark marks. Scrub the potatoes clean, then slice them so that each piece is about 1/2″ thick. 
  • Olive Oil: The olive oil helps the potatoes cook to perfection. They crisp up on the outside, so they have a nice charred outer layer while the inside remains soft and fluffy. If you prefer, you can swap out the olive oil for another cooking oil like canola, grapeseed, or sunflower oil.
  • Seasonings: To flavor the Grilled Sweet Potatoes, I used garlic powder, kosher salt, black pepper, and sage. The garlic adds a bold garlicky flavor while the sage adds an earthy, woody freshness. I used ground spices because fresh herbs will burn with the long cooking time. If you want to add fresh herbs, I recommend adding them at the very end before serving.

How to Make Grilled Sweet Potatoes

Time needed: 30 minutes.

  1. Set-Up

    Preheat your gas grill to 350 degrees, and line a 9×13 inch baking dish with parchment paper. If using a charcoal grill, it will take about 15 minutes for it to heat up. Then wash four sweet potatoes under cold water and slice them into round pieces about a half-inch thick. You can also grease the grill grate to ensure the potatoes don’t stick. round slices of Sweet Potatoes

  2. Season Sweet Potatoes

    Add the extra virgin olive oil and sweet potato slices to a large mixing bowl. Then season with salt, coarse ground black pepper, garlic powder, and sage. Toss to coat the potatoes. Then place the potatoes in a single layer on the prepared baking pan. round slices of seasoned Sweet Potatoes

    Place the baking sheet on the hot grill grate and cook for 6-8 minutes. Then use barbecue tongs to flip the sweet potatoes and cook for 3-4 minutes on direct heat.

Can These Be Made Ahead?

Yes, you can make Grilled Sweet Potatoes ahead, but to have the crispiest texture it’s recommended to grill them and serve them the same day. They’ll last fresh in the fridge for a day or two if you’re wanting to make them for a party. Crisp up in the air fryer or toaster oven before serving!

Alternative Cooking Methods

Stovetop Grilled Sweet Potatoes 

To get the same charred flavor without outdoor cooking, you can cook the sweet potatoes in a grill pan on the stovetop. 

  • For this cooking method, start by seasoning the sweet potatoes according to the original recipe instructions. 
  • Then add the potato pieces to your grill pan and cook over medium heat to medium-high heat. 
  • Cook until charred on one side, then flip and cook until the potatoes are fork-tender.
  • Because there’s less space in a grill pan than on an outdoor grill, you’ll likely have to grill the sweet potatoes in batches.

Frequent Questions

Does it matter how I slice sweet potatoes?

The shape you slice your sweet potatoes into doesn’t matter. Whether you prefer sweet potato wedges, rounds, or planks, any of these shapes can work for this recipe. But, you will want to be careful to cut all the sweet potatoes with a relatively similar thickness so that they cook at an even speed. The thicker the potato slices, the longer they’ll take to cook, and if you slice them too thin, they’ll be quick to burn. 

Do I need to peel sweet potatoes before grilling?

No. It’s up to you if you want to peel the potatoes or leave the skin on. Many people enjoy the texture of grilled sweet potato skin, in which case you should absolutely leave them on. If you don’t peel the potatoes, just be sure to scrub any dirt off the potatoes before grilling. 

Are yams and sweet potatoes the same?

Although the terms sweet potato and yam are sometimes used interchangeably, there are some big differences. You can tell the difference by looking because sweet potatoes have a reddish brown, thin skin, and bright orange flesh. Yams have dark brown, thicker skin and white flesh. Yams are also usually larger than sweet potatoes. As far as how they taste, sweet potatoes have a sweeter, more buttery flavor, whereas yams are more similar to white potatoes. 

Do you need to poke holes in sweet potatoes before grilling?

No. The reason to poke holes in regular potatoes is so that steam can escape from the center when you’re cooking them whole. However, the sweet potatoes are already sliced into pieces for this recipe so the steam won’t get trapped in the same way.
