  • VEGETARIAN – For vegetarians or vegans in the family. A tasty alternative on Taco Tuesdays.
  • HEALTHY – These tacos are filled with roasted vegetables. I used sweet potatoes, red peppers, shallots, and poblano peppers. Sweet potatoes are high in nutrients. They are a fantastic source of vitamins, minerals, and fiber, and may even have cancer-fighting properties. They also support healthy vision, brain function, and the immune system.
  • EASY– You can prep ahead, chopping all the veggies and making the crema. Then it is a quick and easy weeknight meal. You roast all the veggies on a sheet pan. While they are roasting you can make the Chiptole Lime Crema.

How to Roast Sweet Potatoes

  • The secret is using precisely roasted sweet potato cubes that are creamy and sweet on the inside and crisp and delicious on the outside. Following are some tips for roasting sweet potatoes to perfection:
  • Heat over to  400° F.
  • Cut the sweet potatoes into cubes. This is the most time-consuming task for this recipe. Get those cubes nice and tiny, please. Additionally, sweet potato cubes roast more quickly the smaller they are cut.
  • Place them on a baking sheet, toss with olive oil, then sprinkle some homemade taco seasoning on top and toss again.
  • Roast until they are soft on the inside and the outside is a touch crunchy. After 20 minutes, check to see if they are done.

Ingredients for Sweet Potato Tacos

To make these roasted sweet potato tacos, you will need the following ingredients (amounts listed in the recipe below):

  • Sweet potatoes: Diced into 1/2-inch cubes for faster roasting. I peel the potatoes before dicing.
  • Peppers: Red peppers and poblano peppers
  • Taco seasoning, salt, and pepper: To season the sweet potatoes. I used my favorite homemade taco seasoning, but store-bought seasoning works great too.
  • Corn Tortillas: I prefer corn tortillas which makes them gluten-free but you could use flour or your other favorite tortilla.
  • Shallots: Roast or fry for a crispy topping.
  • Toppings: I recommend a generous sprinkle of finely-chopped fresh cilantro and either fresh lime wedges (for a quick meal and to make these vegan tacos) or lime crema (easy to make with a quick blend of plain greek yogurt, lime juice, 1/2 chipotle pepper, and salt). Other optional toppings could include red cabbage, crumbled queso fresco, sliced jalapenos, pickled red onions, pico de gallo, salsa, or anything else that sounds good!
