Preheat oven to 400°F (200°C).
Scrub potatoes, pierce with a fork, rub with olive oil and salt, and bake for 60 minutes or until fork-tender.
While potatoes bake, brown ground beef in a skillet over medium-high heat until fully cooked, draining excess fat.
Add diced onion and garlic to the skillet and sauté for 4-5 minutes until translucent.
Stir in the corn, paprika, cumin, salt, and pepper; cook for 3 minutes then remove from heat.
Slice baked potatoes in half lengthwise and scoop out the centers into a mixing bowl, leaving a 1/4-inch thick shell.
Mash the potato centers and combine with the beef and corn mixture, sour cream, and 1/2 cup of the cheddar cheese.
Spoon the filling back into the potato shells and place on a baking sheet.
Top with the remaining 1/2 cup of cheddar cheese.
Bake for 10-15 minutes until the cheese is melted and bubbly.
Garnish with sliced green onions and serve warm.
