Revisiting a timeless vegetarian taco recipe featuring roasted sweet potatoes, creamy avocado yogurt sauce, and simple pantry ingredients. I originally began preparing these tacos quite a while back, and yet they remain one of those dishes I find myself returning to over and over — they're just so hearty, satisfying, and packed with flavor for an easy weeknight meatless meal. The ingredient list is brief, the instructions are straightforward, and the result is genuinely comforting. On top of that, oven-roasted sweet potatoes feel like the coziest cold-weather comfort food, particularly when tucked into a warm tortilla like a cozy blanket.
The recipe breaks down into two main parts:
- Whip up the creamy avocado yogurt sauce: Just blend Greek yogurt with avocado, garlic, lime juice, salt, and pepper until silky. For a plant-based version, I've included a cashew cream variation in the recipe card below. Vegan mayo also works beautifully in place of the yogurt. Want a brighter, greener flavor? Toss in a handful of cilantro. Craving some heat? Throw in a piece of jalapeño to your liking.
- Roast cubed sweet potatoes tossed with olive oil, salt, pepper, and chili powder until tender and caramelized.
That's really all there is to it! Layer the sauce, sweet potatoes, and black beans into tortillas. On this occasion, I finished mine with pickled onions. Other times, I've added extra diced avocado (shown in the photo below).
And one more thing — I never, ever skip a generous squeeze of fresh lime over the finished tacos for that final burst of brightness!
