Topped with creamy avocado lime sauce, these simple chili-spiced sweet potato tacos make a delicious vegetarian dinner.
This sweet potato taco recipe is an old favorite that I wanted to re-share with you. I first started making these sweet potato tacos years ago, but it’s one of those recipes that I come back to time and time again because it’s such a filling & flavorful vegetarian weeknight dinner option. The list of ingredients is short and the steps are easy – what’s not to love? Plus, I just think roasted sweet potatoes are such a cozy wintertime food, especially when they’re wrapped up into warm tortillas like a big hug.
There are basically two steps to the recipe:
- Make the avocado yogurt sauce: Simply blend together Greek yogurt, avocado, garlic, lime juice, salt, and pepper. If you’re vegan, I’ve listed a cashew cream option in the recipe below. Vegan mayo would also be a great substitute for the yogurt. For a more herbaceous sauce, blend in a handful of cilantro. If you like things spicy, consider adding a chunk of jalapeño, to taste. Alternatively, this Creamy Chipotle Sauce would also be delicious on these tacos if you wanted to change things up from time to time.
- Roast the sweet potatoes with olive oil, salt, pepper, and chili powder.
That’s it! Just assemble the tacos with the sauce, sweet potatoes, and black beans. This time, I topped mine with a few pickled onions. In the past, I’ve topped them with additional diced avocado (see the picture below).
Lastly, I always, always, always finish my sweet potato tacos with a big squeeze of lime for extra pop!
Avocado Sweet Potato Tacos
Ingredients
- 1 medium sweet potato, cubed
- Extra-virgin olive oil, for drizzling
- 1/2 teaspoon chili powder
- 4 to 6 tortillas, I like these white corn & wheat tortillas, or homemade tortillas
- 1 cup black beans, cooked, drained, and rinsed
- Lime slices, for serving
- Sea salt and freshly ground black pepper
Avocado yogurt sauce
- 1/2 cup whole milk Greek yogurt
- 1 small avocado
- 1/2 garlic clove
- Juice of 1 lime
- Sea salt & fresh black pepper
Optional toppings:
- 1 small avocado, diced
- 2 scallions, diced
- Crumbled feta or Cotija cheese
- Pickled onions
- Microgreens or fresh cilantro
Instructions
- Preheat oven to 400° F and line a large baking sheet with parchment paper.
- Toss the sweet potatoes with olive oil, chili powder, salt and pepper, and spread onto the baking sheet. Roast for 20 minutes, or until golden brown.
- Make the avocado yogurt sauce: In a small food processor, combine the yogurt, avocado, garlic, lime juice, and a few generous pinches of salt and pepper. Pulse until smooth. Taste and adjust seasonings. Chill until ready to use.
- Assemble the tacos with a scoop of the sauce, the roasted sweet potatoes, black beans, and desired toppings. Season with salt, pepper, and squeezes of lime.
Notes
Made this tonight, absolutely delicious!
I tweaked a few things to suit my fam’s preferences:
*Added carrots, sweet paprika and cumin to the sweet potato.
*Used non-fat yogurt for the sauce.
*Added more beans and cooked them w/ half a pound of ground beef, garlic powder, chili powder and sweet paprika.
Soo good! I would love to make it w/o the beef next time, but my fam ain’t ready for Meatless Monday yet lol. Also gonna use another sweet potato next time, bc we really liked them
These tacos are Amazing!!! Best combo of flavors and ingredients, excited to have a new favorite!!
Avocado Sweet Potato Tacos is awesome! I just finished it last night and the result was unexpected, my wife and daughter both liked it, which made me happy. Thanks for your recipe.
Somehow this recipe reminded me of Asian pizza called “Banh trang nuong”.
Its difficult to find corn tortillas in my place, do you have a suggestion to replace it with something else…
Hi Marina, you can use flour tacos if you’d like.
I just made this for brunch and think they are terrific! Thanks, I’ll be checking your site again!
For some reason, I love cooking your recipes. It looks delicious, for sure this Avocado Sweet Potato Tacos is going to be on my table tonight. Thank you, for this simple yet delicious looking recipe.
Taught my g-daughter this recipe to teach her how to read a recipe and cook it. Came out delicious.
Love this recipe! I’ve made for dinner several times – these tacos are amazing. Even my husband (who is far from a vegetarian) enjoyed these as well. The avo lime sauce is the perfect addition. Thank you!!
Hi Megan, I’m so glad you’ve been loving these!
These sweet potato tacos were incredibly delicious. I roasted my red onions instead of pickling them because I was out of white vinegar. Paired the meal with a nice rose for a lovely quarantine meal with my hubby! I also just purchased one of your cookbooks and am completely inspired by the many ways you use veggies. Thanks for your delicious ideas. Next…mushroom polenta. Cheers to healthier meals. ☺️👏
Question: If i use avocado mayo as a substitute, do i still blend it along with the other ingredients or Is the mayo a complete substitute for making the yogurt sauce? Thanks
Either – you could use mayo in place of the yogurt or, for a lighter sauce, do 50/50 yogurt and mayo.
So if i opt for mayo i still blend it with avocado, garlic etc?
yes, for this sauce… or you could make this chipotle sauce (with mayo) exactly as it’s written: https://www.loveandlemons.com/chipotle-sauce/ It would be awesome on these tacos as well.
So delicious and easy to make. Thank you!!
I made this meal tonight, and it is SO good! I’m dairy free at the moment and substituted vegenaise for the Greek yogurt in the sauce, and it’s still very good. Thank you for this recipe! It is officially in my family’s meal rotation!
This looks really delicious! As someone trying to eat less meat and more healthy veggie food, I am really excited to find this recipe and try it.
Hi Noemi, I hope you enjoy the tacos!
very very tasty. even my meat loving husband thought it was delicious! I had to use hard taco shells. all the flavors just melled together beautifully.
Hi, do you peel the sweet potatoes before roasting? It looks like you leave them on? Also., any tips on how to cook/warm up the tortillas? Just plain on a pan? Many thanks!
Hi Sheela, nope, I don’t peel them. You can warm the tortillas in the oven (wrapped in foil), in the microwave (no foil), or over a gas flame for a few seconds per side. I hope you enjoy!
