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!

Instructions 

  • 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. I love sweet potatoes. I bet this one Is delicious! I can’t wait to try this!

  2. I cannot rave enough about these tacos. I usually add 1.5 to 2X the seasoning to for more flavor. Also, make sure you cut the sweet potatoes to 1/4 inch–any bigger and it takes much longer to cook.

    I was worried that this meal wouldn’t keep me full, but these tacos (paired with Beth’s taco rice and corn) are very filling. The flavors are fantasic, the recipe is quick, and it’s vegetarian! Thank you Beth!!!

  3. Beth you rock! My boyfriend and I made these tacos tonight and loved them! They are so tasty, easy to make, and aren’t super expensive to prepare. I’ve always used the “Dave’s Mexican Veggie Tacos” recipe on allrecipes.com to make vegetarian tacos, but I plan on using your recipe from now on. Yours require fewer ingredients, less time to prepare, and are just as good or better than Dave’s – especially with the zesty lime sauce! I used sour cream for it and doubled the amt of garlic, and it turned out great. Thanks for the recipe and the beautiful site!

  4. love this concept but the recipe does not specify that the beans should be pre-cooked/canned! i used raw beans (and was especially mislead by the rinse and dry step– which i felt surely meant it was right to use uncooked beans) and it wound up being a mess 

  5. The lime crema cut the sweetness of the sweet potato well, and really made this feel special while it was still cheap and, compared to meat and cheese tacos, healthy! Next time I would add extra cumin and salt, and maybe a little cayenne for heat. I used raw red onion in lieu of the green onion (didn’t have any), and it worked well but green would be better. Adding corn (like others suggested) sounded good, but I really think it’s best kept simple as in the recipe.

    Most important – sweet potatoes 1/4 inch or less! The 1/2 inch took FOREVER to cook, and overwhelmed the black beans in a bite. Still a great recipe.

  6. AMAZING. I could eat tacos every day of the week: beef, bean, chicken, mango, sweet potato, you name it. The lime crema makes these.

  7. So freaking good and so easy! We substituted the black beans for sweet yellow corn and added an extra clove of garlic to the crema. We made this with the taco rice and were stuffed after just a serving of each. Next time, we plan on adding a bit of cayenne to spice things up.

  8. Hi Beth!
    I haven’t tried this recipe… yet. But I just wanted to say thank you for your amazing blog! I’m a college student with a tight budget, but I also love cooking. So I use your blog all the time! Thanks, Beth! You’re my hero!

  9. Mine was delicious – but turned out a little too sweet. Do you think that was the potato? Anybody have suggestions about what I could do to spice it up a little without getting too spicy or too complex?

  10. Hi Beth! Long time eater first time commentor!
    What would you suggest to make this spicy?

    Thank you!

    1. I’ve been a huge fan of thinly sliced fresh jalapeño lately so I would just add a few slices of those to each taco, but you could also toss the sweet potatoes with a little chili and cayenne powder before roasting them. :)

  11. Fantastic! I added canned roasted corn to mine, highly recommend. I also experimented with chipotle mayo instead of the crema, since I don‘t like sour cream. Definitely think this will become a meal staple!

  12. Great recipe! Added a little red pepper and paprika and cooked some chopped white onions along with it. Perfect meatless meal, and so filling!
