The sweet potato and all-purpose barbecue seasoning are just a match made in heaven. These fries also give a vegetarian option a very recognizable barbecue flavor.

Technique tip: Cook over medium heat to prevent the sugars in the rub from burning.

Swap option: Any firm root vegetable will work for this recipe, such as Idaho potatoes, carrots, parsnips, beets or rutabagas.


  • All-Purpose Barbecue Seasoning (makes 1 cup)

    • 1/4 cup granulated sugar
    • 1/4 cup sweet paprika
    • 2½ tablespoons salt
    • 1 tablespoon granulated garlic
    • 1 tablespoon granulated onion
    • 3 tablespoons dark brown sugar
    • 1/2 teaspoon dried oregano
    • 1/2 teaspoon ground coriander
    • 1/2 teaspoon cumin
    • 1 teaspoon chili powder
    • 1/4 teaspoon cayenne
    • 1 tablespoon freshly ground black pepper
  • NYC White Sauce (makes 1¼ cups)

    • 3/4 cup mayonnaise, preferably Hellmann's
    • 1/2 cup labne or plain Greek yogurt
    • 2 tablespoons white distilled vinegar
    • 1 teaspoon freshly squeezed lemon juice
    • 1½ teaspoons granulated garlic
    • 1 teaspoon freshly ground black pepper
    • 1 teaspoon kosher salt
    • 1 teaspoon granulated sugar
    • 1/2 teaspoon dried dill
  • Championship Mustard Sauce (makes 1½ cups)

    • 1/2 cup yellow mustard, preferably French's
    • 1/2 cup ketchup
    • 2 tablespoons hot sauce, preferably, Franks RedHot
    • 2 teaspoons all-purpose BBQ seasoning (recipe above)
    • 1/2 cup honey
    • 1/4 cup light brown sugar
    • 1 tablespoon distilled white vinegar
  • Sweet potato fries

    • 3 sweet potatoes
    • 2 tablespoons vegetable oil
    • 1/4 cup all-purpose BBQ seasoning (recipe above)
    • 1/4 cup sliced chives


For the all-purpose barbecue seasoning:

Combine all ingredients in a mixing bowl and whisk together. Transfer to an airtight container until ready to use.

For the NYC white sauce:

Combine all ingredients in a mixing bowl and whisk to combine. Transfer to an airtight container and refrigerate until ready to use.

For the championship mustard sauce:

Combine all ingredients in a blender, transfer to an airtight container and let sit overnight.

For the sweet potato fries:

1. Wash and cut sweet potatoes into 6 wedges. Toss the sweet potatoes with oil and all-purpose barbecue seasoning in a large mixing bowl and set aside.

2. Preheat grill to medium. Coat grill grates with oil.

3. Place the seasoned sweet potato wedges on the grill and cook for 3 minutes per side to get beautiful grill marks (make sure your grill is not too hot to prevent the sugar in the seasoning from burning). Once the sweet potatoes have cooked for 6 minutes and have the grill marks on them, transfer them to the upper rack of your grill and close the lid and continue cooking for another 12-15 minutes or until the potatoes are tender.

4. Serve with NYC white sauce and/or championship mustard sauce and garnish with sliced chives.
