## Step-by-Step Instructions

## Recipe: Easy Sweet Potato Tacos with Creamy Avocado Sauce
*Prep: 5 min · Cook: 15 min · Serves: 4*

### Ingredients

- 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.

> **RECIPE: 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.

## Frequently Asked Questions

**Q: Can I make these tacos ahead of time?**

A: You can prepare the roasted sweet potatoes and black beans up to 3 days in advance. Store them separately in the fridge. Warm them up and assemble the tacos just before serving. The avocado sauce is best made fresh, but you can make it a day ahead and store it with plastic wrap pressed directly on the surface.

**Q: How do I make the avocado sauce less tangy?**

A: If you prefer a milder tang, use sour cream instead of Greek yogurt, or reduce the lime juice to 1 tablespoon. You can also add a teaspoon of honey to balance the acidity.

**Q: Can I use frozen sweet potatoes?**

A: Yes! Frozen diced sweet potatoes work well. There's no need to thaw them; just toss with oil and spices and roast for an extra 5 minutes or until tender. Keep an eye on them to prevent burning.

**Q: Are these tacos vegan?**

A: To make them vegan, use a plant-based yogurt or omit the yogurt/ sour cream in the avocado sauce and add a bit more avocado. Also skip the cotija cheese or use a vegan alternative. The rest of the ingredients are naturally vegan.
