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 sweet potato fajitas!

Variations

  • Homemade Fajita Seasoning: If you don’t have fajita seasoning on hand, you can make your own using:
    • 2 teaspoons chili powder
    • 1 teaspoon salt
    • 1 teaspoon ground paprika
    • ½ teaspoon onion powder
    • ½ teaspoon garlic powder
    • ½ teaspoon ground cumin
    • ¼ teaspoon cayenne pepper
  • Topping Options: Fresh diced tomatoes and corn salsa can introduce a refreshing sweetness and texture, while a drizzle of sour cream or a dollop of Greek yogurt adds a creamy contrast that complements the spices. For cheese lovers, sprinkle crumbled feta or shredded cheddar. You can also add pickled jalapeño or red onion for a tangy kick.

How to Make Sweet Potato Fajitas

Step #1: Place the sweet potato, bell peppers, onion, and mushrooms in a large bowl. In a small bowl, whisk together the fajita seasoning and oil. Pour the seasoned oil over the top of the vegetables and toss well to coat.

Step #2: Preheat a large skillet over high heat. Once the surface is very hot, add the seasoned vegetables and immediately turn the heat down to medium. Sauté the vegetables until they are tender and slightly blackened, about 6-8 minutes.

Step #3: Serve with warm Soft Tortilla Taco Boats and toppings of choice.

Frequently Asked Questions

Can I use flour tortillas or corn tortillas instead of Soft Tortilla Taco Boats?

Yes, you can substitute Soft Tortilla Taco Boats with flour or corn tortillas. Flour tortillas offer a soft, neutral base, while corn tortillas provide a firmer texture with a distinct flavor. Both can be warmed on a skillet for added warmth and flexibility.

What sides can you serve with the fajitas?

Serving black beans and rice alongside the fajitas is a great choice. These sides not only enhance the meal’s nutritional value but also perfectly complement the flavors of the fajitas.

Storage Info

Store leftover Vegan Sweet Potato Fajitas in an airtight container in the refrigerator; they will stay fresh for up to 3-4 days. While freezing is possible, the texture of the vegetables might become softer upon thawing.

To reheat, use a skillet over medium heat, stirring occasionally, until heated through. For a quick option, you can microwave them, but this might slightly alter the texture.

NOTES

If you are using a medium-sized skillet, cook the fajitas in two batches to avoid overcrowding the pan.
For an added crunch, toast the taco boats prior to serving: Preheat your oven to 325° Fahrenheit (163° Celsius). Arrange the taco boats on a large baking sheet and lightly spritz them with cooking spray or olive oil. Bake in the heated oven for 2-3 minutes, until warm and slightly toasted.

  1. 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!

  2. 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.
