Sweet Potato Tacos
Updated Mar 07, 2026
These Sweet Potato Tacos with black beans make the most delicious vegetarian dinner! Serve them with your favorite toppings for an easy taco night meal.
These sweet potato tacos are a family favorite!
Sweet potatoes are one of my top picks for a vegetarian dinner. They are so delicious when paired with seasonings like cumin, paprika, and chili powder.
These sweet potato tacos feature roasted sweet potatoes and black beans paired with smoky spices and lime juice for a burst of flavor.
Sweet potatoes are perfect for vegetarian mexican recipes, because they are not only nutrient dense (and filling), but their sweetness contrasts perfectly with those smoky flavors and fresh zing-y lime juice.
Another favorite way to eat this yummy combo is in our sweet potato black bean enchiladas.
I prefer to roast mine at super high heat to get some crispy edges. This is key to getting the best flavor on your sweet potatoes!

Ingredients needed

How to make sweet potato tacos
Step 1: Peel and dice your sweet potatoes into small chunks and place them in a large mixing bowl.
Step 2: Drizzle the sweet potatoes with olive oil and add the salt, pepper, cumin, garlic powder, onion powder, and chili powder. Stir until the sweet potatoes are totally coated in oil and spices.
Step 3: Transfer the sweet potatoes to a rimmed baking sheet. Edges are preferred to keep the sweet potatoes from falling off when it’s time to flip and stir them.
Roast the sweet potatoes at 450 degrees for 25-30 minutes, flipping at least once, until the edges are browned.
Step 4: Add the garlic, onion, and olive oil to a large skillet. Cook the mixture over medium heat for 7-10 minutes, or until the onion is soft and translucent.
Step 5: Add the drained black beans, fresh squeezed lime juice, and cooked sweet potatoes to the skillet and stir until heated through.
Taste and adjust the salt or seasonings if necessary and you’re ready to serve your sweet potato tacos!
Scoop some of that yummy filling into soft taco shells and it’s time to eat!

These tacos are plant based, simple, filling, and so flavorful. It’s going to be one of your favorite taco Tuesday dinners!
My personal favorite toppings for sweet potato tacos are sour cream, avocado, and fresh squeezed lime juice.

Delicious! I have made this in the past and we had the leftovers with my daughter this evening. She was oohing and aweing throughout eating the tacos.
Thank you!

So glad you both enjoyed the recipe Lynn!
I need to make these for dinner but people are arriving at 3pm for dinner at 7 and I don’t really want to be cooking too much while they’re here. What can I prep in advance? Can I roast the sweet potatoes in advance and the black beans etc in advance then only combine and heat right before?
I would recommend not making the sweet potatoes in advance as they really taste best fresh. To save prep time, you could mince the garlic and dice the onion and place it in a ziploc bag in the fridge. You could also pre-measure all of the spices and put them in a baggie or container ready to go. That would save you a lot of time!
@Joy Shull, Thanks for the tips!
You’re welcome! Hope you enjoy the recipe 🙂
I just made this taco recipe for the first time and left the table very satisfied. The spices are delicious. I sliced the onions and almost caramelized them. Also, we added sliced avocado that was yummy. Thank you!
10 cloves of garlic?! Just making sure that’s right haha
You can use less if you would like, but yes that is correct. It should be a little less than one bulb of garlic. Maybe 1/2-2/3 of one depending on the size.
I added some soyrizo in the onion stage. And it is delicious!
Delicious! We really enjoyed these for cinco de Mayo dinner last night!
Made these last week and we loved them so much that I’m making them again tonight. Excellent!!
Awesome, so glad you enjoyed the recipe!
