Sweet potato fingerlings (or small wedges) blister and caramelize on the grill. All they need is a final toss with a little butter and a blend of orange zest and mint and you have a healthy side dish that’s anything but ordinary.


  • 2 tablespoons finely chopped fresh mint
  • 2 teaspoons grated orange zest
  • 1 teaspoon raw sugar, such as demerara
  • ⅛ teaspoon kosher salt
  • 1 pound fingerling or small sweet potatoes
  • 1 tablespoon extra-virgin olive oil
  • ¼ teaspoon ground pepper
  • 1 tablespoon melted unsalted butter


  • Preheat grill to medium-high.
  • Combine mint, orange zest, sugar and salt in a small bowl; gently crush together with the back of a wooden spoon. Set aside.
  • If using small sweet potatoes, cut into 1-inch-thick wedges. Toss the sweet potatoes with oil and pepper in a medium bowl. Place in a single layer on the grill or in a grill basket. Cook, turning every 5 minutes, until tender when pierced with the tip of a knife, 20 to 25 minutes total.
  • Transfer the sweet potatoes to a large bowl. Add butter and toss to coat. Serve with the reserved orange-mint gremolata.
