Preparing the Sweet Potatoes

Step 1: Preheat and Prep

Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper for easy cleanup.

In a large bowl, toss the cubed sweet potatoes with olive oil, smoked paprika, cumin, chili powder, garlic powder, salt, and pepper.

Step 2: Roast Until Perfectly Crisp

Spread sweet potatoes evenly on the prepared baking sheet — no overlapping. Roast for 25–30 minutes, flipping halfway through, until the edges are golden and caramelized.

Pro tip: The secret to crisp edges is giving each piece enough space to roast, not steam.

Preparing the Black Beans

Step 3: Sauté the Aromatics

In a skillet, heat olive oil over medium heat. Add chopped onion and cook for 3–4 minutes, until translucent. Add garlic and cook another 30 seconds until fragrant.

Step 4: Season and Simmer

Add black beans, cumin, and chili flakes. Stir to combine, then add a splash of water to loosen. Simmer for 5 minutes until beans are heated through and slightly thickened. Finish with a squeeze of lime juice for brightness.

If you like smoother beans, gently mash a few with the back of a spoon to create a creamier texture.

Making the Lime Crema

In a small bowl, whisk together Greek yogurt, lime juice, zest, honey (or maple syrup), and a pinch of salt. Adjust seasoning to taste — it should be tangy and refreshing.

Refrigerate until ready to use. This crema balances the smoky-spiced sweetness of the tacos beautifully.

Assembling the Tacos

Step 5: Warm the Tortillas

Warm tortillas on a dry skillet for about 15–20 seconds per side until soft and pliable. Keep them wrapped in a clean kitchen towel to stay warm.

Step 6: Build Your Tacos

Layer each tortilla with:

1. A spoonful of black beans.

2. A generous portion of roasted sweet potatoes.

3. A drizzle of lime crema.

4. Toppings like avocado slices, shredded cabbage, cilantro, and salsa.

Add a squeeze of lime and a pinch of flaky salt to finish.

Tips for the Best Sweet Potato and Black Bean Tacos

1. Roast, don’t steam. Overcrowding the pan makes potatoes soggy. Spread them out evenly.

2. Season generously. Sweet potatoes love bold spices like cumin, chili, and paprika.

3. Layer for texture. Combine creamy (beans), soft (potatoes), and crisp (slaw) for balance.

4. Add acid. A squeeze of lime or a drizzle of crema brightens every bite.

5. Warm tortillas properly. Soft, flexible tortillas make assembly easier and more enjoyable.

Make-Ahead and Meal Prep Tips

• Roasted sweet potatoes can be stored in an airtight container for up to 4 days. Reheat in a skillet or oven to crisp them back up.

• Black beans keep well for 3–4 days in the fridge.

• Lime crema stays fresh for up to a week.

• Assemble tacos just before eating for the best texture.

These tacos also pack great for lunch — just store components separately and assemble when ready to eat.

How to Make It Vegan

This recipe is naturally vegetarian, but can easily be made vegan by:

• Using dairy-free yogurt or cashew crema for the lime sauce.

• Skipping cheese or using a vegan feta or cheddar substitute.

• Checking your tortillas — some store-bought versions contain dairy, so opt for corn or certified vegan options.

---

Optional Add-Ons

Want to elevate your tacos even more? Try:

• Pickled red onions for tang.

• Crunchy pepitas (pumpkin seeds) for texture.

• Sliced radishes for color and freshness.

• Hot sauce drizzle for an extra kick.

Troubleshooting

My sweet potatoes are too soft:
They likely steamed from overcrowding. Use a larger sheet pan or two pans.

Beans are too dry:
Add a splash of broth or water and simmer until creamy.

Tortillas breaking apart:
Warm them longer or lightly steam under a damp towel.

Flavors taste flat:
Add extra lime juice or a pinch of salt — acidity and seasoning bring everything to life.

Corn tortillas for an authentic flavor, flour tortillas for a softer bite.
