Preheat the oven: Preheat your oven to 400°F (200°C).
- Bake the Sweet Potatoes: Wash and scrub the sweet potatoes thoroughly. Pierce them a few times with a fork and place them on a baking sheet lined with parchment paper. Bake for 40-45 minutes, or until tender when pierced with a fork.
- Prepare the Skins: Remove the sweet potatoes from the oven and allow them to cool for about 10 minutes. Slice them in half lengthwise. Scoop out the flesh, leaving about a 1/4-inch border to form a boat-like shape.
- Season the Skins: Brush the hollowed-out skins with olive oil and season with salt and pepper. Place them back on the baking sheet and bake for another 10-12 minutes, until crispy and golden brown.
- Prepare the Filling: Mash the scooped-out sweet potato flesh in a bowl. Stir in Greek yogurt (or sour cream), shredded cheese, smoked paprika, and any optional fillings like black beans and corn. Season with salt and pepper to taste.
- Fill the Skins: Once the skins are crispy, spoon the filling back into each skin. Top with additional cheese and bake for another 5-7 minutes, until the cheese is melted and bubbly.
- Garnish and Serve: Sprinkle with chopped green onions and fresh cilantro or parsley before serving. Serve hot and enjoy!
