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 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!
