- 2 medium sweet potatoes, peeled and diced
- 1 tbsp olive oil
- 1 tsp chili powder
- 1/2 tsp cumin
- 1/2 tsp garlic powder
- 1/4 tsp salt
- 1 can (15 oz) black beans, drained and rinsed
- 8 corn tortillas
- 1 ripe avocado
- 1/4 cup plain Greek yogurt or sour cream
- 2 tbsp lime juice
- 1/4 cup fresh cilantro, chopped
- 1/4 cup crumbled cotija cheese (optional)
- 1 lime, cut into wedges
📋Instructions
- 1
Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper.
- 2
In a medium bowl, toss the diced sweet potatoes with olive oil, chili powder, cumin, garlic powder, and salt until evenly coated. Spread on the prepared baking sheet in a single layer.
- 3
Roast the sweet potatoes for 12-15 minutes, until tender and slightly browned, stirring halfway through.
- 4
While the sweet potatoes roast, prepare the avocado sauce: In a small food processor or blender, combine the avocado, Greek yogurt (or sour cream), lime juice, and a sprinkle of salt. Blend until smooth and creamy. If too thick, add a tablespoon of water to thin.
- 5
Warm the corn tortillas in a dry skillet over medium heat for about 30 seconds per side, or wrap in a damp paper towel and microwave for 20-30 seconds.
- 6
To assemble the tacos, place a few spoonfuls of roasted sweet potatoes onto each tortilla. Top with black beans, a drizzle of avocado sauce, and a sprinkle of cilantro and cotija cheese if using. Serve with lime wedges on the side.
💡 Pro Tips
- •Cut the sweet potatoes into uniform 1/2-inch cubes for even cooking.
- •For a smokier flavor, add 1/4 teaspoon smoked paprika along with the chili powder.
- •If you prefer a thinner sauce, add more lime juice or water until it reaches your desired consistency.

Pro Cooking Tip
For extra crispy sweet potatoes, don't overcrowd the baking sheet. Giving them space allows the hot air to circulate, resulting in perfectly browned edges. If you need to double the recipe, use two baking sheets.
Customization Ideas
These tacos are incredibly versatile. Feel free to swap the black beans for pinto beans or refried beans. Add some protein by throwing in grilled chicken or seasoned ground beef. For a bit of heat, top with sliced jalapeños or a dash of hot sauce. You can also use flour tortillas if you prefer, but corn tortillas add a nice authentic touch.
Serving Suggestions
Serve these sweet potato tacos with your favorite sides like Mexican street corn, cilantro lime rice, or a simple green salad. They also pair wonderfully with a cold margarita or a refreshing agua fresca. For a complete meal, add a side of guacamole and chips.
Storage and Meal Prep Tips
Store any leftover components separately in airtight containers in the refrigerator for up to 3 days. The avocado sauce may brown slightly; press plastic wrap directly onto the surface to minimize oxidation. To reheat, warm the sweet potatoes in the oven or microwave and gently reheat the tortillas in a skillet. Assemble just before serving for the best texture.
