Sweet Potato and Black Bean Tacos

Sweet potato and black bean tacos are my go-to weeknight dinner when I want something healthy, satisfying, and quick. These vegetarian tacos combine roasted sweet potatoes with protein-rich black beans for a perfectly balanced meal that won’t spike your blood sugar. Plus, they’re naturally customizable with whatever toppings you have on hand.

I still remember making these on a busy Tuesday when I was craving Mexican food but wanted something lighter. The aroma of cumin and smoked paprika filling my kitchen as the sweet potatoes roasted was incredible. Now, these sweet potato and black bean tacos have become a weekly staple in my meal rotation. They’re perfect for anyone looking for healthy dinner recipes that actually taste good and keep you energized for hours.

What You’ll Need for These Veggie Tacos

I always use firm, medium-sized sweet potatoes for the best texture and sweetness. Pro tip: look for sweet potatoes that feel heavy for their size, with smooth skin and no soft spots. Here’s everything you’ll need:

• 2 medium sweet potatoes, peeled and diced
• 1 tablespoon olive oil
• 1 teaspoon ground cumin
• 1/2 teaspoon smoked paprika
• 1/2 teaspoon chili powder
• Salt and pepper, to taste
• 1 can (15 oz) black beans, rinsed and drained
• 8 small corn or whole wheat tortillas
• 1/2 cup red onion, finely chopped
• 1/2 cup fresh cilantro, chopped
• 1 avocado, sliced
• 1 lime, cut into wedges
• Optional: salsa or hot sauce for serving

I prefer corn tortillas for their authentic flavor and naturally gluten-free quality, but whole wheat tortillas add extra fiber if that’s your preference.

How to Make Sweet Potato and Black Bean Tacos

I recommend cutting your sweet potatoes into uniform 1/2-inch cubes so they roast evenly and get those beautiful caramelized edges.

Step 1: Preheat your oven to 425°F (220°C). This high temperature is key for getting crispy, caramelized edges on your sweet potatoes.

Step 2: In a large mixing bowl, toss the diced sweet potatoes with olive oil, cumin, smoked paprika, chili powder, salt, and pepper. Make sure every piece is evenly coated with the spice mixture. The sweet potatoes should glisten with oil but not be dripping.

Step 3: Spread the seasoned sweet potatoes on a baking sheet in a single layer. Avoid overcrowding, as this causes steaming instead of roasting. If needed, use two baking sheets. Roast for 25-30 minutes, flipping them halfway through with a spatula. You’ll know they’re done when they’re fork-tender and have golden-brown caramelized spots.

Step 4: While the sweet potatoes roast, warm your tortillas. Wrap them in foil and place in the oven during the last 5 minutes of roasting, or heat them in a dry skillet over medium heat for 30 seconds per side. If you have a gas stove, you can also char them directly over the flame for about 10 seconds per side for extra flavor.

Step 5: Heat the rinsed black beans in a small pot over medium heat for 3-5 minutes until warmed through. You can add a pinch of cumin or garlic powder if you want extra flavor.

Step 6: Assemble your sweet potato and black bean tacos by layering ingredients on each warm tortilla. Start with 2-3 tablespoons of roasted sweet potatoes, add about 2 tablespoons of black beans, then top with chopped red onion, fresh cilantro, and avocado slices.

Step 7: Finish by squeezing fresh lime juice over each taco. The acidity brightens all the flavors beautifully. Add salsa or hot sauce if you like extra heat, then serve immediately while everything is still warm.

Perfect Pairings for Your Low-Glycemic Tacos

These sweet potato tacos pair wonderfully with fresh, light sides that complement their hearty nature.

Mexican-Style Cauliflower Rice: This low-carb side adds extra vegetables without weighing you down. The lime and cilantro flavors echo the taco toppings perfectly.

Crispy Cabbage Slaw: A crunchy, tangy slaw adds textural contrast and helps cut through the richness of the avocado. Plus, the probiotics in fermented slaw support gut health.

Black Bean and Corn Salad: Double down on the southwestern flavors with a cold salad featuring lime vinaigrette. It’s refreshing and adds even more plant-based protein.

Grilled Street Corn (Elote): For a more indulgent pairing, charred corn with cotija cheese and chili powder brings authentic Mexican street food vibes to your sweet potato and black bean tacos dinner.

Storing Your Taco Components

Store the roasted sweet potatoes and black beans separately in airtight containers in the refrigerator for up to 4 days. I recommend keeping the fresh toppings like avocado, cilantro, and red onion separate until you’re ready to assemble. This prevents the tortillas from getting soggy and keeps everything fresh.

When you’re ready to eat, reheat the sweet potatoes in a 350°F oven for about 10 minutes or microwave them in 30-second intervals until warm. The black beans can be reheated in a small pot or microwave. Warm your tortillas fresh each time for the best texture.

Pro tip: the roasted sweet potatoes actually freeze beautifully for up to 3 months. Spread them on a baking sheet to flash-freeze first, then transfer to a freezer bag. This makes meal prep super easy for busy weeks.
