Why You’ll Love This Recipe

  • Grilling sweet potatoes might be my favorite way to prepare the savory, sweet vegetable. The foil makes for easy clean-up, and you can cook the potatoes alongside your favorite grilled main dishes.
  • Sweet potatoes are a healthy side dish you can serve with everything from steak and chicken to fish.

Is It Better to Wrap Sweet Potatoes in Foil?

Wrapping the grilled sweet potatoes in foil prevents them from becoming dry or charring from the flames. Plus, you infuse the potatoes with smoky flavor and aromatics from fresh herbs since you can wrap them together.

What You Need to Make this Recipe

  • Sweet Potatoes: Wrap the grilled sweet potatoes in foil for a side that cooks alongside any entree. I usually grill the sweet potatoes whole, but you can cut them into sweet potato cubes, sweet potato wedges, or slice them before adding them to an aluminum foil packet.
  • Olive Oil: Coating the potatoes in oil encourages them to become crispy as they cook, and since you’re wrapping the sweet potatoes in foil, they will become crispy without charring. 
  • Spices: Season the grilled sweet potatoes with kosher salt and coarse ground pepper.
  • Thyme: Add fresh thyme springs to the potatoes, or try a sprig of rosemary or oregano.
  • Butter: Finish the potatoes with a tab of butter.

Additions and Substitutions

  • Spices: I share a very basic seasoning for this recipe, but I enjoy experimenting with different spices based on what I am serving the potatoes with. A few of my favorites are Slap Ya Mama Seasoning Recipe, Santa Maria Seasoning, and seasoning salt. If you prefer a sweeter flavor, consider topping the potatoes with maple syrup, honey, or brown sugar. 
  • Herbs: Fresh herbs like thyme, sage, or parsley can add freshness and flavor to sweet potatoes. Chop them finely and sprinkle over cooked potatoes, or wrap the herbs in the foil with the potatoes.
