This vibrant sweet potato and black bean taco filling transforms everyday ingredients into a flavor-packed vegetarian meal that even committed carnivores will devour. The caramelized sweet potatoes and roasted peppers create a satisfying texture while the honey-lime sauce brings everything together with a perfect balance of sweet and tangy notes.
I first created this recipe when trying to use up leftover sweet potatoes and black beans. What started as kitchen improvisation has become our family's favorite Meatless Monday tradition, with everyone customizing their tacos exactly how they like them.
Ingredients
- Sweet potatoes: Provide natural sweetness and hearty texture, choose firm ones with unblemished skin
- Black beans: Offer protein and fiber, canned varieties work perfectly but rinse well
- Bell peppers: Add crunch and vitamin C, look for firm peppers with glossy skin
- Corn kernels: Contribute subtle sweetness and color contrast, frozen corn works great
- Honey: Balances the savory elements, local honey brings subtle flavor variations
- Lime juice: Adds brightness and cuts through the richness, use fresh for best flavor
- Cilantro: Brings that signature taco freshness, choose bunches with vibrant green leaves
Step-by-Step Instructions
- Prep the Spice Blend:
- Combine all the spices in a small bowl, mixing thoroughly to ensure even distribution. This creates the foundation of flavor that will coat every sweet potato cube.
- Season the Sweet Potatoes:
- Toss sweet potato cubes with olive oil until each piece has a light coating, then add the spice mixture. Make sure to stir thoroughly so every cube gets an even coating of the spices. This ensures consistent flavor in every bite.
- Initial Roasting:
- Spread sweet potatoes in a single layer on your baking sheet, giving them space to roast rather than steam. The first 20 minutes at high heat helps them develop caramelization while starting to soften.
- Prepare the Peppers:
- While sweet potatoes cook, toss peppers with olive oil and a pinch of salt and pepper. Using the same bowl saves dishes and picks up residual spices for extra flavor.
- Combine and Continue Roasting:
- Add seasoned peppers to the partially cooked sweet potatoes, distributing evenly. This staggered roasting approach ensures each vegetable cooks perfectly without some becoming too soft.
- Create the Sauce:
- Whisk together honey, lime juice, and chopped cilantro. The sauce should be loose enough to drizzle but thick enough to coat the vegetables when stirred.
- Add Beans and Corn:
- Once vegetables are roasted, add black beans and corn to the hot pan. The residual heat will warm them without overcooking.
- Apply the Sauce:
- Pour the honey cilantro lime mixture over everything while still hot. Stir gently but thoroughly to ensure every component gets coated with the sweet tangy sauce.
- Final Roasting:
- The last short roasting period allows the sauce to caramelize slightly and adhere to all the ingredients, creating complex flavor and helping everything hold together.
