Save to Pinterest I threw these tacos together on a Tuesday night when the fridge was nearly empty and my energy was even lower. I had sweet potatoes rolling around in the drawer, a lone can of black beans, and tortillas that needed using. What started as a scrappy dinner became something I crave weekly. The sweet potatoes caramelize in the oven while you chop toppings, and suddenly you have this colorful, smoky, satisfying meal that feels like you tried way harder than you did.
The first time I made these for friends, someone asked if I had ordered them from the new taco spot downtown. I laughed and pointed at the messy baking sheet still cooling on the stove. We ate them standing around the kitchen island, lime juice dripping everywhere, and I watched three people go back for seconds. That is when I knew this recipe was a keeper.
Ingredients
- Sweet potatoes: Choose firm ones with smooth skin, peel them quickly, and cut into even cubes so they roast at the same rate.
- Black beans: Rinse them well to wash away the canned taste, and warm them just enough to make them silky.
- Red onion: Roasting mellows the bite and adds a sweet, jammy layer that balances the spice.
- Corn tortillas: Warm them or they will crack when you fold them, a lesson I learned the hard way.
- Cumin, smoked paprika, and chili powder: This trio gives the sweet potatoes a smoky, earthy backbone that makes the whole taco sing.
- Avocado and lime: The creamy and the acidic, they pull everything together and make each bite feel complete.
- Red cabbage and cilantro: Crunch and freshness, they wake up the whole plate and add color you can taste.
Instructions
- Prep the sweet potatoes:
- Preheat your oven to 425°F and line a baking sheet with parchment. Toss the sweet potato cubes and sliced red onion with olive oil and all the spices until every piece is coated, then spread them out so they roast instead of steam.
- Roast until caramelized:
- Slide the pan into the oven and roast for 18 to 20 minutes, tossing halfway through. You will know they are ready when the edges turn golden and the sweet potatoes yield easily to a fork.
- Warm the black beans:
- While the vegetables roast, heat a splash of olive oil in a skillet and add the rinsed black beans. Stir them gently for a few minutes until they are warm and glossy, then season with a pinch of salt.
- Warm the tortillas:
- Heat each tortilla in a dry skillet for a few seconds per side, or wrap them in a damp towel and microwave for 20 seconds. Pliable tortillas are everything.
- Assemble and serve:
- Layer roasted sweet potatoes and onions, black beans, shredded cabbage, avocado slices, and cilantro into each tortilla. Add cheese, sour cream, salsa, and a squeeze of lime, then serve them hot with extra lime wedges on the side.
Save to Pinterest One night I made these after a long day and sat on the porch with a plate balanced on my lap. The sun was setting, the lime was tart, the sweet potatoes were still warm, and for a few minutes everything felt easy. That is what a good taco does, it gives you a moment to breathe.
How to Get the Best Texture
Cut your sweet potatoes into uniform cubes so they cook evenly, and make sure to toss them halfway through roasting. The parchment paper keeps them from sticking and makes cleanup a breeze. If you want extra crispy edges, spread them out more and crank the oven up to 450°F for the last five minutes.
Toppings That Make It Shine
The beauty of these tacos is in the contrast, creamy avocado against crunchy cabbage, smoky sweet potatoes next to bright lime. I love adding crumbled cotija or feta for a salty punch, but they are just as good without it. A drizzle of hot sauce or a spoonful of salsa verde takes them over the top.
Making It Your Own
Swap the sweet potatoes for butternut squash or even roasted cauliflower if that is what you have. Add sliced jalapeños if you like heat, or toss in some corn for sweetness. I have made these with leftover roasted vegetables from another meal and they were just as good.
- Try a chipotle crema by mixing sour cream with a bit of adobo sauce.
- Add pickled red onions for extra tang and crunch.
- Use flour tortillas if you prefer them softer and more filling.
Save to Pinterest These tacos have become my go to when I want something nourishing without the effort. They are proof that simple ingredients and a hot oven can turn into something worth gathering around.
