Ingredients
- 2 medium sweet potatoes (approximately 600g / 1.3 lbs), peeled and diced into 1.5 cm (0.6 inch) cubes
- 1 can (425g / 15 oz) black beans, rinsed and drained
- 5 mL (1 tsp) ground cumin
- 5 mL (1 tsp) chili powder
- 8 corn tortillas (about 15 cm / 6 inch diameter)
- 1 ripe avocado, sliced
- 120 mL (1/2 cup) salsa for serving, or to taste
- 15 mL (1 tbsp) olive oil
- 2.5 mL (1/2 tsp) fine sea salt, plus more to taste
- Optional: 1-2 lime wedges for a fresh squeeze
- Optional: 30g (1/4 cup) fresh cilantro, chopped, for garnish
Instructions
- Preheat your oven to 200°C (400°F). In a large mixing bowl, combine the peeled and diced sweet potatoes with the olive oil, ground cumin, chili powder, and a pinch of fine sea salt. Toss thoroughly until the sweet potatoes are evenly coated. This ensures every piece gets a burst of flavor and a beautiful caramelization during roasting.
- Spread the seasoned sweet potatoes in a single layer on a large baking sheet. Roast in the preheated oven for approximately 20 minutes, or until the sweet potatoes are fork-tender and exhibit slight caramelization around the edges. Flipping them halfway through can encourage even browning.
- While the sweet potatoes are roasting, warm the corn tortillas. Heat a dry skillet over medium heat and place each tortilla in the pan for about 20 seconds per side, or until pliable and slightly charred in spots. Wrap the warmed tortillas in a clean kitchen towel to keep them warm and soft.
- Reheat the rinsed black beans. If they seem a bit dry, add a splash of water (about 15 mL or 1 tbsp) to a small pan over medium heat, then add the drained black beans. Stir occasionally until heated through, about 3-5 minutes.
- Assemble the tacos immediately. Fill each warmed tortilla generously with a spoonful of the reheated black beans and a portion of the roasted sweet potatoes. Top with fresh avocado slices and your favorite salsa. For an extra zing, squeeze a lime wedge over the fillings and sprinkle with fresh chopped cilantro, if using. Serve hot and enjoy!

Essential Success Tips
- Dice sweet potatoes uniformly: Aim for roughly 1.5 cm (0.6 inch) cubes so they cook evenly and caramelize beautifully at the same rate.
- Don't overcrowd the baking sheet: Give the sweet potatoes space to breathe. If the sheet is too crowded, they'll steam instead of roast, leading to a less crispy texture.
- Warm tortillas properly: Warming tortillas makes them pliable and prevents them from breaking. Don't overheat, as they can become brittle. A quick zap in the microwave (covered with a damp paper towel) also works.
- For extra zing: Always finish with a squeeze of fresh lime juice and a sprinkle of chopped fresh cilantro. These bright additions elevate all the flavors.
- Taste and adjust seasoning: Before assembling, taste the roasted sweet potatoes and black beans. Add more salt, cumin, or chili powder if you feel they need a little extra punch.
Professional Cooking Secrets
- The Maillard Reaction is your friend: Ensure your oven is fully preheated and don't rush the roasting time. The slightly browned, caramelized bits on the sweet potatoes are where much of their flavor deepens and truly shines.
- Layering textures is key: For a truly exceptional taco, think about contrasting textures. The soft beans and potatoes are excellent, but adding something crunchy like shredded cabbage, pickled onions, or even toasted pumpkin seeds can elevate the experience significantly.
- Make your own salsa: While store-bought is convenient, a fresh pico de gallo or a simple avocado-lime crema (blended avocado, lime juice, cilantro, a touch of water or dairy-free yogurt) will take your tacos from great to extraordinary.

Notes
- Storage: Leftover roasted sweet potatoes and black beans can be stored separately in airtight containers in the refrigerator for up to 3-4 days. Reheat gently before assembling fresh tacos.
- Variations: Feel free to add other roasted vegetables like bell peppers or onions. For a touch of heat, add a pinch of cayenne pepper to the sweet potatoes or top with pickled jalapeños. A sprinkle of crumbled feta or cojita cheese (if not strictly vegan) also adds a lovely salty tang.
- Meal Prep: Roast the sweet potatoes and prepare the beans ahead of time for a super quick assembly on taco night.
Frequently Asked Questions

Yes, this recipe is naturally gluten-free as long as you use corn tortillas, which are traditionally made from corn masa. Always double-check ingredient labels to ensure no gluten-containing additives are present.
How can I add more protein to these tacos?

Beyond salsa and avocado, consider toppings like pickled red onions for a tangy crunch, a drizzle of creamy cashew sour cream, finely shredded cabbage or lettuce, or even a sprinkle of toasted pumpkin seeds for added texture.
