Vegan Sweet Potato Fajitas. Tender sweet potato and smoky mushrooms stand in for meat in this easy fajita recipe!
As someone who has been eating meat-free for the past few months, I often find myself with leftover veggies hanging out in the fridge.
I’ve come up with quite a few ways to use them, including turning them into fritters, making grilled veggie skewers, and even putting them in savory pancakes (it’s better than it sounds, trust me!).
My latest and greatest idea is vegan fajitas!
I almost *always* have a few sweet potatoes on hand, as well as onion, bell pepper, and a few lonely mushrooms.
Old El Paso™ Fajita Seasoning and Soft Tortilla Taco Boats are a pantry staple in my house, so Mexican food is always just a few minutes away.
So, why not create a delicious, sweet potato fajitas recipe?
Fresh lime and cilantro (two of my all time favorite flavors) are the perfect garnishes to liven up this savory dish.
Of course, if you’re not eating vegan you could always top these sweet potato fajita boats with a bit of sour cream or Greek yogurt.
These really couldn’t be any easier to make!
Just slice up all your veggies (keeping them uniform in size and thickness will help them cook evenly), toss them with oil and fajita seasoning, then throw onto a sizzling hot pan and let them get all caramelized and smoky.
Serve in warm taco boats with your favorite toppings – this would be a great time to make some quick guacamole!
Here’s the Recipe!

Ingredients
- 1 large sweet potato - peeled and sliced into thin strips (about 2 cups)

MMMMMM this was amazing! Loved it! Definitely going to be a regular in our house! Thanks you!
I also had left over sweet potatoes, mushrooms and peppers in the fridge, hence the reason I bumped into this recipe!
I enjoyed, although I was missing something, so I cooked up some rice and added it to my boats.
Thank you very much for this simple recipe!
Sounds delish! I love ideas like this because even if I’m not vegan I can make this along with regular fajitas and eat a little lighter while still filling my families tummies.
Such a great idea!!
