Ingredients & Suggested Substitutions

This recipe is made with simple pantry ingredients and a few key taco toppings. Here’s the full list…

Sweet potatoes: we love using organic yams but you can also use any type of sweet potato variety.
Oil: a good oil for baking – we like using avocado or olive oil.
Black beans: use basic canned black beans to make things easy.
Tortillas: you can use corn, wheat, or a gluten-free tortilla!
Avocado: for a creamy topping!
Lime: for some acidity.
Red onion: for flavor!
Vinegar: for pickling the red onion.
Sugar: to balance the acidity for the pickled onions – any natural sweetener or table sugar works.
Spices: you’ll need paprika, cumin, chili powder.
Garlic powder: for flavor!

How to Make Sweet Potato Tacos

Then toss diced sweet potatoes with oil, salt, chili powder, cumin, and paprika – roast in oven for 25 minutes – flip halfway through to roast evenly.

Tips For Success

Type of sweet potatoes: I recommend using organic sweet potatoes because they will naturally be sweeter than non-organic.
Warm-up tortillas: room temperature tortillas are never really that good. I recommend warming your tortillas by either wrapping them in foil and popping them in the oven for at least 5 minutes, microwaving for 15-20 seconds, or using a gas-burning on LOW to individually heat them up.
Make it gluten-free: swap regular wheat tortillas with corn or your favorite gluten-free tortilla brand. We love Siete!
Additional toppings: add even more flavor by using additional toppings like cilantro, pico de gallo, slaw, salsa, or adding hot sauce for spice.
How to store: to properly store leftovers – place ingredients in separate airtight containers or ziplock bags and refrigerate for up to 4 days. Then reheat as needed and re-assemble.

Recipe FAQs

Do I need to peel the sweet potatoes? Peeling the potatoes is totally optional! A lot of the nutrients for sweet potatoes are in the skin, so because of this, I recommend leaving the skin on.
