Preheat the oven to 400°F (200°C).
Wash and scrub the russet potatoes thoroughly.
Poke holes in each potato with a fork.
Rub each potato with olive oil and sprinkle with salt.
Place the potatoes directly on the oven rack and bake for 45-50 minutes.
While the potatoes bake, heat the chili in a saucepan over medium heat.
Once the potatoes are baked, remove them from the oven and let them cool slightly.
Split each potato lengthwise and fluff the insides with a fork.
Spoon the heated chili into each potato and top with shredded cheddar cheese.
Return the stuffed potatoes to the oven until the cheese is melted, about 5-7 minutes.
Remove from the oven, garnish with sour cream and sliced green onions.
