Ingredients
This serves about four. Have your favorite taco toppings ready to go.
- 2 medium sweet potatoes, peeled and diced
- 1 can (15 oz) black beans, drained and rinsed
- 2 tablespoons olive oil
- 1 teaspoon each cumin, smoked paprika, and chili powder
- 8 small tortillas
- Toppings: avocado, red onion, cilantro, lime, and salsa

How to make it
Roasting the sweet potato is the only real cooking step — the rest is assembly.
- Preheat oven to 425°F (220°C)
- Toss diced sweet potato with olive oil and spices, spread on a tray
- Roast 20–25 minutes until tender and caramelized, stirring once
- Warm the black beans and the tortillas
- Fill tortillas with sweet potato and beans, add toppings, and squeeze lime over
Tips and variations
Add a handful of spinach to the warm beans for extra greens, or top with crumbled feta or a dollop of Greek yogurt. For extra char, warm the tortillas directly over a gas flame for a few seconds.
Leftover roasted sweet potato and beans make a great grain bowl the next day.
Nutrition notes
This is a fiber-rich, plant-powered meal. Sweet potatoes deliver vitamin A and complex carbs, while black beans provide protein and fiber that keep you full. Avocado adds healthy fats to round it out.
Frequently asked questions
Can I make these tacos ahead?
Yes — roast the sweet potatoes and prep the beans in advance, then assemble at mealtime. The components keep well for a few days.
How do I make them vegan?
They’re naturally vegan — just skip dairy toppings like feta or yogurt, or use plant-based versions.
What can I use instead of sweet potato?
Butternut squash or regular potatoes work well, or try roasted cauliflower for a different twist.
The takeaway
Sweet potato and black bean tacos are a fast, affordable, plant-forward dinner that doesn’t sacrifice flavor. Roast, warm, assemble — and enjoy a meal that’s as nourishing as it is satisfying.
