Ingredients

  • 1/3 cup (40 grams) Raw Pepitas optional but recommended
  • 3 cups (415 grams) Diced Sweet Potato peeled & diced into 1/4 inch pieces, about one medium potato
  • 1 1/2 tablespoons Vegetable Oil like olive or avocado oil
  • 1 3/4 cups (425 grams) Cooked Black Beans homemade or about one can, drained
  • 3/4 teaspoon Fine Sea Salt
  • 1 teaspoon Ground Cumin *see note
  • 1/2 teaspoon Chili Powder
  • 1/4 teaspoon Chipotle Chili Powder or more Chili Powder
  • 1/4 teaspoon Garlic Granules
  • 1/8 teaspoon Onion Powder
  • 1/4 Lime
  • 8, 6-7 inch (15-17 cm) Soft Flour Tortillas **see note
  • 2 1/2 cups (130 grams) Shredded Pepper Jack Cheese or Monterey Jack Cheese

For the Toppings

  • 1/2 cup (70 grams) Cotija Cheese or Queso Fresco
  • 2 1/2 cups (75 grams) Romaine Lettuce chopped

Chili Lime Avocado Sauce***

  • 1 (275 grams) Avocado sliced in half, skin/pit removed, about one medium
  • 8 sprigs Cilantro ends trimmed
  • 1 Green Onion chopped into small pieces
  • 4-6 Pickled Jalapeno Pepper Rings adjust to taste
  • 1 tablespoon + 1 teaspoon Fresh Lime Juice about 3/4 of a lime
  • 1/4 + 1/8 teaspoon Fine Sea Salt
  • 5-7 tablespoons Water as needed

Instructions

  • Arrange an oven rack in the center of the oven. Line a sheet pan with parchment paper. Set aside.
    In a small pan, add the pepitas, and set in the oven. Preheat the oven to 400 degree Fahrenheit (204 Celsius). The pepitas will toast while the oven preheats for about 10-13 minutes, or until fragrant and lightly golden brown around the edges. Set aside to cool.

Make the Filling

  • In a medium mixing bowl, drizzle the oil over the diced sweet potatoes. Mix well, then add the salt, cumin, chili powders, garlic granules and onion powder. Stir to distribute the spices. Transfer the sweet potatoes to the prepared sheet pan in one even layer then roast in the 400 degree Fahrenheit preheated oven for 15-20 minutes or until tender.
  • Meanwhile, to the same mixing bowl (no need to clean), add the drained black beans. Once the sweet potatoes come out of the oven, transfer the potatoes to the mixing bowl with the beans, squeeze 1/4 lime over the ingredients, and mix throughly. Set aside.
  • On two sheet pans (no parchment needed), arrange your tortillas so they're not overlapping, four per pan. Spoon the potato/bean mixture down the center of each tortilla. Sprinkle jack cheese over the tops. Transfer to the oven and bake until the cheese is melted and bubbly and the sweet potato and black bean mixture is warmed through, about five minutes.

For the Chili Lime Avocado Sauce***

  • Into the work bowl of a food processor, add the avocado, cilantro, green onion, pickled pepper rings, lime juice, and salt. Process until almost smooth and creamy stopping to scrape down the bowl several times while processing. Add water to thin as desired while processing, adding 1-2 tablespoons at a time. Taste for salt adjustment.

Assemble the Tacos

  • Once the tacos are out of the oven, top with lettuce, avocado sauce, pepitas and cojita cheese. Share right away.
  • To Store: allow the tacos to cool, then wrap in foil (without added toppings). The tacos can be reheated in the oven with the wrapping on. For microwave heating, wrap in parchment paper, then in foil. When ready to reheat, remove the foil. 

Notes

*Taco Seasoning Sub: substitute 2 1/4 teaspoons taco seasoning for the cumin, chili powder, chipotle chili powder, garlic granules and onion powder. 
**Corn Tortillas: these tacos are delicious with corn tortillas. You'll need 16 instead of 8 flour tortillas so you can double layer the tacos on the sheet pan (they're more tender than flour and can tear easily).
***Avocado Crema: have you tried my Avocado Cream Sauce? It's fabulous with these tacos too, although a bit richer due to added sour cream.  
Dairy Free or Vegan: omit the cheese entirely in this recipe and top the tacos with something creamy like Pepita Crema or Charred Jalapeño Guacamole
