Tacos are one of my favorite summer quick dinner fixes. They don’t have to be complicated and they’re not too heavy. Fresh toppings keep the meal light and summery, and allow for personalization. And while tacos are usually meat-centric, these Sweet Potato Tacos are a great example that you can make a great taco even without meat!

What’s in a Sweet Potato Taco?

To fill these Sweet Potato Tacos I made a quick sweet potato and black bean hash, then topped the tacos with an insanely light and fresh lime crema. Okay, so it’s not actually Mexican crema, but it’s a lime flavored sour cream that you can substitute for real crema if your grocery store doesn’t carry a large selection of Hispanic ingredients. At any rate, the lime crema is what really makes these Sweet Potato Tacos special and I found it so irresistible that I had a hard time not licking it off the spoon. It’s so goooood.

What Kind of Tortillas Should I Use?

Traditionally, tacos are made with corn tortillas, but this recipe is flexible and you can use flour tortillas if that’s what you prefer. Either way, toasting the tortillas a little beforehand really amplifies their flavor and adds a lot to the taco!

What Else Can I Add to the Tacos?

Want to get extra fancy? Try adding some thinly sliced jalapeños, avocados, or pickled red onions to the top of these Sweet Potato Tacos!

What to Serve with Sweet Potato Tacos

I served these Sweet Potato Tacos with Cilantro Lime Rice and some fresh Pico de Gallo, which you can either serve on the side or add to the taco itself. Cilantro Lime Coleslaw would also make an awesome side dish for these tacos!

Prep 20 minutes

Total 40 minutes


Lime Crema

  • 8 oz. sour cream ($0.83)
  • 1 fresh lime ($0.69)
  • 1/4 tsp salt ($0.02)
  • 1 clove garlic ($0.08)


  • 1 Tbsp olive oil ($0.13)
  • 2 cloves garlic ($0.32)
  • 1.25 lbs. sweet potato ($1.22)
  • 1 15oz. can black beans ($0.59)
  • 1 tsp ground cumin ($0.10)
  • Salt and Pepper to taste ($0.05)
  • 2 green onions ($0.19)
  • 1/4 bunch fresh cilantro (optional) ($0.17)
  • 8 small (taco sized) tortillas ($0.75)


  • Prepare the crema first to allow the flavors time to blend. Mince one clove of garlic and use a zester or small holed cheese grater to scrape the thin layer of green zest from the lime. Add the minced garlic, 1 tsp of the zest, about 1 tsp of the lime juice, and 1/4 tsp salt to the sour cream. Stir the ingredients to combine then refrigerate until ready to use.
  • Peel the sweet potatoes, then cut them into small cubes (about 1/4 to 1/2 inch square). Heat a large skillet over medium flame, then add the olive oil and two cloves of minced garlic. Sauté the garlic for about a minute or just until it becomes fragrant. Add the diced sweet potato and a couple tablespoons of water. Sauté the sweet potato until they become soft and just begin to fall apart. Add another couple tablespoons of water during cooking if the skillet becomes dry before the sweet potatoes are soft.
  • Meanwhile, drain and rinse the can of black beans. Once the sweet potatoes are soft, add the black beans to the skillet. Season with the cumin, and salt and pepper to taste. Sauté just until the beans are heated through.
  • Slice the green onions and pull the cilantro leaves from the stems. Roughly chop the cilantro. Stir the sliced green onions into the skillet. Add the cilantro to the skillet if desired, or use it to top each taco.
  • Prior to filling each tortilla, heat them in a dry skillet until slightly browned and crisp on each side, or carefully toast them over an open flame. Smear a small amount of the lime crema down the center of the tortilla, then top with a scoop of the sweet potato and black bean hash. Add fresh cilantro if desired.

How to Make Sweet Potato Tacos – Step by Step Photos

Lime Crema ingredients in a small bowl

Make the lime crema first so the flavors have time to blend. Mince one clove of garlic and use a zester or a small holed cheese grater to remove the thin layer of green zest from the lime. Add 1 tsp of the zest and about 1 tsp of the lime juice to the sour cream, along with the minced garlic and 1/4 tsp salt. Stir the ingredients to combine, then refrigerate the crema until you’re ready to use it.

Sauté Garlic in a skillet

Heat a large skillet over medium flame, then add 1 Tbsp olive oil and 2 cloves of minced garlic. Sauté for one minute or just until the garlic becomes nice and fragrant.

Sauté Sweet PotatoesPeel and dice a sweet potato (about 1.25 lbs.) into small 1/4-1/2″ cubes. You want the cubes to be very small so they cook quickly. Add them to the skillet, along with a couple tablespoons of water to generate steam. Sauté the sweet potatoes until they are soft. Add more water, if needed, if the skillet dries up. The steam will help soften the sweet potatoes.

Add Black Beans to sweet potatoes and Season

While the sweet potatoes are cooking, drain and rinse one 15oz. can of black beans. Once the potatoes are soft, add the black beans, 1 tsp of cumin, and salt and pepper to taste. Sauté the skillet for a few minutes more, or just until the beans are heated through.

Add Green Onions and Cilantro

Slice two green onions and roughly chop 1/4 bunch of cilantro. Fold the green onions into the sweet potato has and sprinkle the cilantro on top, if desired.

Toast Tortillas on open flame

Whether you’re using flour or corn tortillas, I find that you get a lot more flavor and strength (to hold all those delicious fillings) if you toast the tortillas first. You can do this in a dry skillet, or over an open flame. Doing this over an open flame goes really fast and requires a lot of attention, so if you’re not comfortable you can just lay the tortillas in a skillet, one by one, until they get toasty on each side. The skillet is slower and there is less room for error, but they don’t get quite as blackened.

Spread lime crema on tortillas

Once the tortillas are toasted, it’s time to build the Sweet Potato Tacos! Smear a little lime crema down the center of each tortilla.

And finish with an extra little sprinkle of cilantro. And maybe more of that amazing lime crema, because it’s just that good.

  1. We had this recipe for lunch today, and 100% agree the lime crema is delicious. We used whole wheat tortillas, and I sauteed half a diced yellow onion, stirred in the black beans, plus chili powder, garlic powder & lots of cumin. We had leftover baked sweet potatoes so I stirred them in last to warm through. We liked garlic powder in place of the fresh garlic for this recipe. We topped the taco with lime crema, pepitas & cilantro. So good!!

  2. Love the cream. Going to use leftover potatoes and beans for breakfast tomorrow morning with a fried egg on top!

  3. Solid vegetarian taco, and makes for really great meal prep/leftovers. The sweet potato filling is fine, but definitely needs the crema to spice it up. The crema is awesome, but the raw garlic in it give you rank garlic breath. Worth it.

  4. The crema was the bomb, but I found the tacos to be kinda one-note otherwise.
    My easy, inexpensive suggestion to make them a bit spicier, smokier and much more flavorful (and still keep them vegetarian) is to add a small (7 oz) can of chipotle peppers in adobo. Slice the peppers up and add them to the skillet with the beans.

  5. Made these again to tonight. These are true budget-friendly tacos that still tastes so good! Perfection! 

  6. Made these yesterday and have been enjoying them for lunch. They are so yummy without the guilt. Follow the recipe exactly. It’s perfect. 

  7. My absolute favorite thing to cook from this blog! These are soooo good! I sometimes will cook a little steak to add too and wow it’s amazing!

  8. I thought that I didn’t like sweet potatoes, but I’m on my second Budget Bytes meal plan – doing the Vegetarian one this time – and I honestly have to say that I’m convinced now. Great recipe!

  9. So I won an air fryer in a raffle – I had no interest in it (was hoping for the dutch oven) but the next day I was gifted a bag of sweet potatoes so figured sure, why not. One of the things I made was this (since I’ve made it several times and knew the fam loves it). Omg, who knew that AF sweet potatoes were missing from my life. They are perfect in about 10 minutes, which left me time to pull together your cumin lime coleslaw (no sour cream so no crema :( and chop some veggies for toppings. Our vegetable consumption has skyrocketed since getting this magnificent silly machine, luckily this site is bursting with veggies..

  10. These look awesome, and a lot like some sweet potato tacos a restaurant in my neighborhood has on their menu. Theirs add kale and walnuts to the mix, and are always hard for me to resist. Can’t wait to try your version!

  11. I love this recipe so much!! Super easy to make and the leftovers heat up so well and taste delicious. I recommend this to my friends often.

  12. What could I substitute to make the lime crema vegan? I can’t wait to try these tacos.

  13. I know you posted this a long time ago but it was delicious, I made it for my daughter and I for dinner.
