Ingredients
Sweet Potato Black Bean Tacos
- 2 lbs sweet potato, 1/2 inch cubes
- 3 tbsp olive oil, divided
- 1 tsp chili powder
- 1 tsp cumin
- 1 tsp smoked paprika
- 1 tsp salt, divided
- 2 cans black beans, 15 oz each, drained
- 3 cloves garlic, minced

How to Make Sweet Potato Black Bean Tacos
- **Roast.** Preheat oven to 425F. Toss sweet potato cubes with 2 tablespoons oil, chili powder, cumin, smoked paprika, and 1/2 teaspoon salt. Spread on a sheet pan and roast for 25 minutes, flipping halfway.
- **Simmer.** Heat remaining oil in a skillet over medium. Sauté garlic for 30 seconds, then add beans with their liquid, cumin, and lime juice. Simmer 5 minutes, mashing half the beans.
- **Blend.** Combine avocado, sour cream, cilantro, lime juice, and remaining 1/2 teaspoon salt in a blender with 2 tablespoons water. Blend until smooth.
- **Char.** Warm tortillas over a gas flame or in a dry skillet until lightly charred and pliable.
- **Assemble.** Fill each tortilla with beans, roasted sweet potato, and a drizzle of avocado crema.
- **Top.** Finish with pickled red onions, cilantro, and a squeeze of lime.
Why This Recipe Works
Roasting the sweet potatoes at 425F with oil and chili powder is what gives you those crispy, jammy edges that taste like candy. The high heat caramelizes the natural sugars while the spices bloom into the oil. Skimping on the oil or going lower temp means soft, pale sweet potatoes.
Black beans are the muscle of this plant based tacos recipe. Simmered with garlic, cumin, and a splash of lime, they go from canned-bean-ordinary to deeply flavored in 5 minutes. Mashing half the beans against the pan creates a creamy, refried-style texture that holds together in the tortilla.
Charring the tortillas over a direct flame or in a dry skillet is what lifts these from weeknight dinner to taqueria worthy. Flame charring adds smoke and makes the tortillas pliable instead of cracking. A 20 second sear per side is all you need. For more ideas, see our Thai Basil Ground Chicken.
Tips
- Store the components separately in the fridge for up to 4 days.
- Reheat sweet potatoes in the air fryer at 375F for 3 minutes to bring back the crisp.
- Char the tortillas over a gas flame or in a dry skillet for the best flavor.
- Cut sweet potato cubes the same size so they cook evenly.
- Make the avocado crema right before serving. It browns fast even with lime juice.
- Add a pickled vegetable for acidic contrast. Pickled red onions are a game-winning topping.
Variations
- Swap black beans for pinto or refried beans.
- Add cojita or feta cheese on top for a salty finish.
- Use butternut squash or delicata squash instead of sweet potato.
- Make burrito bowls instead, over cilantro lime rice.
- Add grilled corn kernels for sweetness and crunch.
- Make them spicy with chipotle chili powder on the sweet potatoes.

Common Mistakes to Avoid
- Overcrowding the sweet potatoes: Sweet potatoes steam instead of roasting when packed too close. Use a full sheet pan and give them space.
- Using cold tortillas straight from the bag: Char them over a flame or in a dry skillet for pliability and smoky flavor.
- Skipping the lime juice: Acid balances the sweetness of the potatoes and the richness of the beans. Squeeze lime on everything.
- Making the avocado crema too early: Avocado browns fast. Blend the crema within 30 minutes of serving.
