These Black Bean Sweet Potato Tacos started as a fridge clean-out dinner and quickly became a regular in our house. After a long day of errands and kid chaos, I grabbed sweet potatoes, a can of black beans, and some tortillas, and somehow ended up with a dinner everyone loved. Simple, filling, and no complaints. That’s a win.

This is one of my go-tos when I need something fast, meatless, and family-friendly. Whether it’s a busy weeknight or a quick Meatless Monday dinner, these tacos always come through – and cleanup takes no time!

Tips before you get started

  • Dice the sweet potatoes evenly to ensure they roast at the same rate and get those perfect golden edges.
  • Don’t overcrowd the baking sheet – spread the potatoes in a single layer so they roast instead of steam.
  • Stir the black beans into the potatoes while they’re still hot so they warm up without needing an extra pan.
  • Warm your tortillas just before assembling to keep them soft and pliable – this helps prevent tearing.
  • If your guacamole is thick, spread it on the tortilla like a base layer – it helps the toppings stick better.
  • Serve with lime wedges on the side so everyone can add a fresh pop of acidity to taste.

Ingredients needed

Here’s everything you’ll need to make these Black Bean Sweet Potato Tacos. Full measurements are listed further down in the recipe card.

sweet potato taco ingredients
  • Lime wedges: optional, to garnish, lemon works too.
  • Sweet potatoes: peeled and diced into ½-inch cubes. I like getting fresh, but you can also use frozen and thawed.
  • Olive oil: or avocado oil will work
  • Taco seasoning: use my homemade taco seasoning for best results
  • Kosher salt
  • Black beans: canned, rinsed and well drained
  • Guacamole: make your own or use store-bought
  • Corn tortillas or flour tortillas. Whichever you like best.
  • Cherry tomatoes: chopped
  • Olives: sliced
  • Cilantro: optional, freshly chopped

Substitutions

Need to swap an ingredient or two? Here are some easy options that still work great with this recipe:

  • Black beans: Pinto beans or white beans can be used in place of black beans.
  • Sweet potatoes: Use butternut squash or regular potatoes for a similar texture and roast time.
  • Corn tortillas: Substitute with flour tortillas if you prefer.
  • Guacamole: Try mashed avocado with a pinch of salt and lime juice if you’re short on time.

Common Questions

How can I prevent the tortillas from tearing when assembling the tacos?

To keep tortillas pliable and prevent tearing, warm them just before assembling. You can heat them in a dry skillet over medium heat for about 30 seconds per side or wrap them in a damp paper towel and microwave for 20-30 seconds.

Are these tacos suitable for a gluten-free diet?

Yes, as long as you use certified gluten-free corn tortillas. Always check the label to be sure.

How can I add more protein to this meal?

Try adding a sprinkle of feta or a spoonful of Greek yogurt on top. For extra protein, you can also add Cilantro Lime Shrimp right into the tacos. Or serve them alongside a high-protein side like Keto Avocado Deviled Eggs or Oven Baked Chicken Wings.
