Ingredients

For the Roasted Sweet Potatoes

2 pounds sweet potatoes (3 to 4 medium sweet potatoes), peeled and sliced into 1-inch chunks
2 tablespoons olive oil
¼ teaspoon cayenne pepper (omit if sensitive to spice)
¼ teaspoon fine salt

For the Spicy Black Beans

1 tablespoon olive oil
1 small yellow or white onion, finely chopped
Fine salt
2 teaspoons ground cumin
¼ teaspoon chili powder
2 cans black beans, rinsed and drained (or 3 cups cooked black beans)
⅓ cup water
1 teaspoon sherry vinegar or lime juice
Freshly ground black pepper, to taste

For the Avocado-Pepita Dip

2 avocados, pitted
1 cup lightly packed fresh cilantro (mostly leaves, some small stems are ok)
½ cup pepitas
1 small jalapeño, seeded and roughly chopped, or ¼ teaspoon red pepper flakes (go easy if sensitive to spice)
2 cloves garlic, roughly chopped
2 tablespoons lime juice (about 1 medium lime) or 1 tablespoon sherry vinegar
2 tablespoons water
½ teaspoon fine salt
Freshly ground black pepper, to taste

For Assembly

8 to 10 small corn tortillas
Crumbled feta cheese
Suggested garnishes: Pickled jalapeños or pickled radishes or pickled red onions, torn cilantro, hot sauce, etc.

Instructions

Prepare the Sweet Potatoes

1 Preheat the oven to 425°F (218°C) and line a large, rimmed baking sheet with parchment paper for easy clean-up. Using parchment paper prevents sticking and makes cleanup effortless while ensuring even browning.
2 Toss the prepared sweet potatoes with the 2 tablespoons olive oil, ¼ teaspoon cayenne pepper (if using) and ¼ teaspoon salt in a large mixing bowl. Make sure each piece is well-coated for optimal caramelization.
3 Arrange the seasoned sweet potatoes in a single layer on the prepared baking sheet, ensuring pieces don’t overlap. Bake for 30 to 40 minutes, tossing halfway through with a spatula, until the sweet potatoes are fork-tender and caramelizing at the edges with golden-brown spots.

Make the Spicy Black Beans

4 While the sweet potatoes roast, warm 1 tablespoon olive oil in a large saucepan over medium heat until it shimmers. Add the finely chopped onions and a generous sprinkle of salt to help them soften faster.
5 Cook the onions, stirring occasionally with a wooden spoon, until they have softened and are turning translucent, about 5 to 8 minutes. You’ll know they’re ready when they smell fragrant and have lost their sharp bite.
6 Add the 2 teaspoons ground cumin and ¼ teaspoon chili powder and cook for about 30 seconds while stirring constantly. This brief toasting releases the spices’ essential oils and prevents them from tasting raw.
7 Pour in the black beans and ⅓ cup water. Stir to combine, cover the pan, and reduce heat to maintain a gentle simmer for 5 minutes. The water helps create steam for even heating.
8 Remove the lid and use a potato masher or fork to mash up at least half of the beans, creating a chunky, hearty texture. Remove from heat, stir in the 1 teaspoon sherry vinegar, and season with additional salt (about ¼ teaspoon or more to taste) and freshly ground black pepper. Cover and keep warm until ready to serve.

Create the Avocado-Pepita Dip

9 First, toast the ½ cup pepitas in a cast iron skillet over medium heat, stirring often with a wooden spoon, until they are fragrant and starting to make little popping noises, about 5 minutes. This toasting step adds incredible nutty depth to the final dip.
10 Transfer the toasted pepitas to a small bowl and set aside to cool. Scoop the flesh from 2 ripe avocados into a food processor or high-powered blender.
11 Add the 1 cup fresh cilantro, chopped jalapeño, 2 cloves garlic, 2 tablespoons lime juice, 2 tablespoons water, and ½ teaspoon salt to the food processor. Blend until completely smooth, scraping down the sides of the processor bowl as necessary with a silicone spatula.
12 Add almost all of the toasted pepitas (reserve 2-3 tablespoons for garnish) and pulse just until the pepitas are chopped into small pieces. You want some texture remaining, not a completely smooth puree. Taste and adjust salt as needed, then transfer to a serving bowl.

Warm and Assemble

13 To warm the tortillas, heat a large skillet over medium heat and warm the tortillas in batches of 2-3 at a time, flipping to warm each side for about 30 seconds. Alternatively, you can warm them directly over a low flame on a gas range using tongs.
14 Stack the warmed tortillas on a plate and cover with a clean tea towel to keep them warm and pliable. This prevents them from drying out and cracking when you fill them.
15 To assemble each taco, spread a generous spoonful of the spicy black beans down the middle of each tortilla, then top with roasted sweet potato chunks and a dollop of the avocado-pepita dip.
16 Garnish with crumbled feta cheese, reserved toasted pepitas, and any additional toppings like pickled jalapeños, torn cilantro, or your favorite hot sauce. Serve immediately while everything is warm.

Recommended Equipment and Kitchen Tools

Essential Tools (for best results):

Large rimmed baking sheet – A heavy-duty sheet pan ensures even heat distribution and prevents warping at high temperatures, crucial for properly caramelized sweet potatoes

Perfect Pairing Suggestions

Beverage Pairings:
A crisp Mexican lager or wheat beer complements the earthy sweet potatoes without overwhelming the delicate avocado dip. For wine lovers, a Sauvignon Blanc or unoaked Chardonnay echoes the lime and cilantro flavors beautifully. Fresh agua frescas made with lime, cucumber, or watermelon provide refreshing non-alcoholic options that cleanse the palate between bites. Hibiscus iced tea or sparkling water with lime also work wonderfully for casual dining.

Side Dish Recommendations:
Mexican street corn salad (esquites) adds complementary flavors and textures while staying in the same cuisine family. A simple jicama and radish slaw with lime dressing provides cooling crunch that balances the warm, spiced elements. Cilantro-lime rice or quinoa makes these tacos more filling for heartier appetites. Pickled red onions and jalapeños add acidic brightness that cuts through the rich avocado dip perfectly.

Complete Meal Ideas:
Start with guacamole and baked tortilla chips or ceviche for a cohesive Mexican-inspired menu. Follow the tacos with coconut flan or tres leches cake for dessert, or keep it lighter with grilled pineapple with lime and chili powder. For entertaining, set up a taco bar with multiple salsas, hot sauces, and additional toppings so guests can customize their experience.

Occasion Suggestions:
These tacos shine at casual dinner parties, Taco Tuesday celebrations, or weekend meal prep sessions. They’re perfect for outdoor entertaining since components can be prepared ahead and assembled quickly. The vibrant colors and fresh flavors make them ideal for spring and summer gatherings, though the warming spices work beautifully for cozy fall dinners too.

Pro Tips and Troubleshooting

Professional Techniques:
Don’t overcrowd the baking sheet when roasting sweet potatoes – use two sheets if necessary to ensure proper caramelization. Salt the sweet potatoes immediately after tossing with oil to help draw out moisture and concentrate flavors. Toast spices in the dry pan for 30 seconds before adding oil to maximize their aromatic compounds. Taste and adjust seasoning at every step, especially the avocado dip which can vary significantly based on avocado ripeness and lime acidity.

Common Mistakes and Solutions:
Mushy sweet potatoes result from cutting pieces too small or overcooking – aim for 1-inch chunks and check at 25 minutes. Bland black beans happen when you skip the spice toasting step or under-season – the mixture should taste slightly over-seasoned on its own since it balances with mild tortillas. Grainy avocado dip occurs when avocados aren’t ripe enough – they should yield to gentle pressure and have no hard spots.

Storage and Make-Ahead Strategies:
Roasted sweet potatoes keep refrigerated for 4-5 days and reheat beautifully in a 400°F oven for 8-10 minutes. Black bean mixture actually improves overnight as flavors meld – store covered in refrigerator for up to 1 week. Avocado dip stays green for 2-3 days when stored with plastic wrap pressed directly onto the surface to prevent oxidation. Assemble tacos just before serving to prevent soggy tortillas.

Scaling and Presentation:
Double the recipe easily for meal prep or entertaining – use two baking sheets for sweet potatoes and a larger pot for beans. For elegant presentation, serve components in separate bowls family-style with warmed tortillas wrapped in colorful kitchen towels. Garnish strategically with reserved pepitas, lime wedges, and fresh cilantro for restaurant-quality appearance.
