Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Scrub the sweet potato clean, prick it several times with a fork, and rub the skin with the olive oil.
Place the sweet potato on the baking sheet and roast for 45 to 50 minutes, or until it is tender when pierced with a knife.
While the potato is roasting, finely dice the yellow onion and mince the garlic clove.
Heat a non-stick skillet over medium heat and add the ground beef and onion, breaking the meat apart with a spatula.
Cook until the beef is browned and the onion is translucent, then stir in the minced garlic for the last 60 seconds of cooking.
Season the beef mixture with sea salt, black pepper, and smoked paprika, stirring well to combine.
Once the sweet potato is finished, slice it down the center lengthwise and gently fluff the orange flesh with a fork.
Spoon the seasoned beef mixture into the center of the potato and top with a cold dollop of cottage cheese.
Garnish with freshly chopped parsley and serve immediately while the potato is hot.
