How to Make Mexican Sweet Potato Wedges with Avocado-Cilantro Sour Cream:

Recipe Ingredients:

Here’s everything you’ll need to make this Mexican sweet potato recipe along with how to prep. See the recipe card below for the exact quantities.

Ingredient Notes and Substitutions:

  • Sweet Potatoes: Four to six medium to large sweet potatoes of any variety will work. I like to select similar-sized potatoes so the wedges are of similar size. If you prefer not to peel the potatoes, just make sure you scrub them well and blot them dry.
  • Olive Oil: No need to use a high-quality oil here. Canola or vegetable oil is also fine.
  • Garlic Powder and Onion Powder: I generally only use these dried spices in spice blends or in rubs–seldom as a substitute for the real thing.
  • Smoked Paprika: This spice of Spanish origin is made from pimento peppers that are smoked and dried over an oak fire which gives it a deep red color and rich smoky flavor. It has many applications, but you’ll really love it in chili.
  • Cayenne Pepper: If the chili powder and smoked paprika are spicy enough for you, feel free to leave out.

Step-By-Step Instructions:

  • Gather and prep all the ingredients.
  • Peel the sweet potatoes and cut them into thick wedges.
  • Place on a cast iron griddle or baking pan. If you don’t have one, line a baking sheet with parchment paper.
  • Drizzle the potatoes with olive oil.

  • Combine all the spices and seasonings and sprinkle over the potatoes.
  • Toss to coat and spread the potatoes back out on the griddle, pan or prepared baking sheet.
  • You can also toss the potatoes with the oil and spices in a mixing bowl and then spread out on the griddle, pan or baking sheet.

  • While the potatoes are roasting, make the Avocado-Cilantro Sour Cream.
  • Simply combine them all in a food processor or blender and voila!
  • MAKE AHEAD:  Combine the spice blend and store in a covered bowl. Peel and cut the potatoes into wedges then refrigerate for up to a day. Toss with the oil and spices then spread out and roast when needed. The Avocado-Cilantro Sour Cream can be prepped and combined a day ahead of time.

Chef Tips and Tricks:

  • If time allows, soak the sweet potato wedges in a bowl of water for 1-2 hours before roasting. This will help to make them crispier.
  • I’m really in love with the cast iron baking pan shown in the photos. Because it’s cast iron, clean-up is pretty easy. You can also use a large cast-iron skillet to roast the potato wedges or line a baking sheet with nonstick aluminum foil or parchment paper for easy clean-up.

Frequently Asked Questions:

Can I leave out the hot chiles?

If you feel it’s going to be too hot for you, simply leave them out. Or, remove the seeds and membranes to take the bite out of the peppers but still have the flavor.

Can I make Mexican Sweet Potato Wedges ahead of time?

Combine the spice blend and store in a covered bowl. Peel and cut the potatoes into wedges then refrigerate for up to a day. Toss with the oil and spices then spread out and roast when needed. The Avocado-Cilantro Sour Cream can be prepped and combined a day ahead of time.

What else can I use this spice rub on?

This easy rub is also delicious on chicken or pork.
