Sweet Potato Tacos with Lime Crema

Tacos are one of my favorite summer quick 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. For 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.

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

Sweet Potato Tacos with Lime Crema

These light and refreshing Sweet Potato Tacos are filled with a simple sweet potato and black bean hash, and topped with a tangy lime crema. 

Total Cost $5.14 recipe / $1.29 serving
Prep Time 20 minutes
Cook Time 20 minutes
Total Time 40 minutes
Servings 4 (2 tacos per serving)

Ingredients

Lime Crema

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

Tacos

  • 1 Tbsp olive oil $0.13
  • 2 cloves garlic $0.32
  • 1.25 lbs. sweet potato $1.22
  • 15 oz. black beans $0.59
  • 1 tsp 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

Instructions

  1. 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.

  2. 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.

  3. Meanwhile, drain and rinse the 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.
  4. 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.
  5. 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.

Lime Crema

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 for Sweet Potato Tacos

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 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

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.

Build Sweet Potato Tacos

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.

Excuse me while I just grab one of these… 

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.
