The Mexican seasoning Tajín, with its mild spiciness and tangy undertones, pairs beautifully with sweet potatoes. Waffle-shaped fries are the perfect vessel for capturing the flavor. A creamy dipping sauce completes the experience.

Ingredient Checklist


Instructions Checklist
  • Position racks in upper and lower thirds of the oven; preheat to 450 degrees F.

  • Using a hand-held mandoline fitted with a crinkle blade, cut sweet potatoes into waffle rounds.

  • Combine oil and Tajín in a large bowl. Add the sweet potatoes and stir to coat. Spread the slices in a single layer on each of 2 baking sheets. Roast, rotating the pans halfway through, until tender, 15 to 18 minutes.

  • Meanwhile, combine sour cream, cilantro, lime juice and salt in a small bowl. Serve the sauce with the sweet potatoes.


Tip: Tajín is a Mexican seasoning blend made with mild chili powder, dehydrated lime juice and salt. Look for it in the spice section of a Mexican market, in the Mexican aisle of well-stocked grocery stores or online. To substitute your own blend for this recipe, combine 1 1/2 teaspoons chili powder, 1 1/2 teaspoons lime zest and 1/4 teaspoon salt. Learn more about Tajín and get additional ideas for what to use it on.
