How To Make Sweet Potato Tacos: A Step-by-Step Process
These sweet potato tacos can be made in a few easy steps.
Follow the instructions below:
Step 1: Bake the Sweet Potatoes
Preheat your oven to 400°F. Line a rimmed baking sheet with parchment paper and set aside.

In a large bowl, toss the sweet potatoes with ground cumin and olive oil. Season with salt and pepper to taste.

Arrange them on the baking sheet and roast in the oven for approximately 20 to 25 minutes or until brown and slightly crisp around the edges.
Step 2: Pickle the Onions

While the sweet potatoes are roasting, simmer water, vinegar, salt, and sugar in a small saucepan.
Place the onions in a glass jar and pour in the vinegar mixture. Let cool for 10 to 15 minutes before refrigerating.
We recommend preparing the pickled onions well in advance for maximum flavor.
Step 3: Create the Avocado Sauce

In a blender, combine avocado, sour cream, garlic, and lime juice. Blend until smooth and creamy.
Step 4: Assemble the Tacos

Spread a dollop of the avocado sauce over each tortilla and top with the roasted sweet potatoes, red beans, pickled red onion, and fresh parsley.
Serve and enjoy!
Expert Tips To Nail This Taco Recipe
- Spread your sweet potatoes in a single layer. Overcrowding can lead to steaming instead of roasting, which might prevent those deliciously caramelized edges from forming.
- Add some flavor. Enhance the flavor of your pickled onions by adding a few peppercorns, a bay leaf, and a clove of garlic to the pickling liquid.
These aromatics will infuse the onions with subtle, complex flavors that complement the sweet potatoes.
- Warm your tortillas beforehand. Warm your tortillas before assembling the tacos to make them more pliable and toasty.
This simple step adds another layer of warmth and comfort to the tacos, ensuring every bite is as satisfying as it is delicious.

Is There a Way To Make the Avocado Sauce Spicier?
