Equipment

  • Rimmed baking sheet
  • Parchment paper
  • Large mixing bowl
  • Small saucepan
  • Glass jar or heatproof bowl for pickling onions
  • Blender or food processor
  • Cutting board and knife
  • Measuring cups and spoons

Ingredients

For the Pickled Red Onions

  • 1 red onion halved and thinly sliced
  • ½ cup water
  • ½ cup apple cider vinegar
  • 1 teaspoon salt
  • 2 teaspoon sugar

For the Roasted Sweet Potatoes

  • 1 large sweet potato cubed
  • 1 tablespoon olive oil
  • 1 teaspoon ground cumin
  • Sea salt and black pepper to taste

For the Avocado Lime Sauce

  • 1 avocado
  • ½ cup sour cream
  • 1 clove garlic
  • 1 lime juiced

For assembling

  • 1 14-oz can red kidney beans rinsed and drained
  • 4 large tortillas (or 8 small)
  • ½ cup fresh parsley chopped

Instructions

  • To make the pickled onions, heat water, vinegar, salt, and sugar in a small saucepan to a steady simmer.
  • Place red onion in a glass jar. Pour the vinegar mixture over the onions. Cool for 10-15 minutes at room temperature and then transfer to the refrigerator to chill. The pickled onions will have the best flavor if made in advance.
  • Preheat oven to 400℉. Line a rimmed baking sheet with a piece of parchment paper for easy clean up.
  • In large bowl, toss sweet potatoes with olive oil and ground cumin. Season with salt and pepper, to taste. Arrange on prepared baking sheet. Roast 20-25 minutes or until brown and slightly crisp around the edges.
  • Meanwhile, combine avocado, sour cream, garlic, and lime juice in a blender. Blend until completely smooth and creamy.
  • Assemble tacos by spreading a dollop of avocado sauce on each tortilla, followed by roasted sweet potato chunks, black beans, pickled red onion, and fresh parsley. Enjoy!

Notes

  • Pickled onions taste best when made at least 2 to 3 hours in advance. Overnight is even better for a deeper flavor.
  • You can warm the tortillas briefly in a dry skillet or directly over a gas flame for better texture before assembling.
  • For a dairy-free version, substitute the sour cream with a thick unsweetened dairy-free yogurt.
  • If you prefer more heat, add a pinch of chili flakes or a dash of hot sauce to the avocado sauce.
  • These tacos are designed to be open-faced, but you can fold them and serve them as traditional tacos if using smaller tortillas.
  • Leftover pickled onions keep well in the refrigerator for up to 1 week in an airtight container.
