Boil potatoes: Place potatoes in a large pot, cover with cold salted water then bring to a boil. Simmer until slightly resistant when pierced with a sharp knife or fork, about 10 minutes, depending on size. Drain well and allow to cool.
Let cool: Once cool enough to handle, slice potatoes in half lengthwise and into wedges.
Mix ingredients: In a small bowl, mix together olive oil, thyme, salt, and pepper. Brush this mixture on sweet potatoes.
Grill: Heat grill to medium-high, lightly oil grill rack and grill potatoes until grill marks appear and potatoes are cooked through, flipping once. This should take about 7-8 minutes.
Serve: Serve wedges with a dipping sauce, like ketchup, mustard or homemade garlic aioli.
Notes
olive oil – avocado oil will work as well.fresh thyme – this is optional, but really helps to increase the flavor profile!
