Rinse the sweet potatoes thoroughly under running water. Using a fork, pierce each potato several times to allow steam to escape during baking. Arrange them on a baking sheet lined with parchment paper for easy cleanup.
Place the baking sheet in the preheated oven and bake the sweet potatoes for approximately 45-60 minutes. They're ready when a fork can easily slide into the flesh.
While the sweet potatoes are baking, heat the olive oil in a large skillet over medium heat. Add the diced red onion and red bell pepper to the skillet, sautéing them for about 5 minutes until they begin to soften and become fragrant.
Incorporate the minced garlic along with the ground cumin, smoked paprika, and chili powder into the skillet. Sauté for an additional minute, allowing the spices to become aromatic.
Next, stir in the rinsed black beans and corn, cooking the mixture for an additional 5 minutes to ensure everything is heated through. Season generously with salt and pepper to enhance the flavors.
Once the sweet potatoes are cooked, remove them from the oven and allow them to cool for a few minutes for easier handling. Carefully slice each sweet potato down the center, creating a pocket for the stuffing.
Using a fork, gently fluff the insides of each sweet potato, creating a light and airy texture. Generously fill each pocket with the savory black bean and corn mixture.
If you’re using cheese, sprinkle some shredded cheddar on top of each filled sweet potato. Return them to the oven for an additional 5 minutes, or until the cheese is melted and bubbly.
Finally, remove from the oven and garnish each stuffed sweet potato with freshly chopped cilantro. Serve them immediately with lime wedges on the side for that extra burst of freshness.
