Preheat your oven to 400°F (200°C).
Wash and pierce the russet potatoes with a fork.
Bake the potatoes on a baking sheet for 40-50 minutes until tender.
Remove the potatoes from the oven and let them cool slightly.
Once cool, peel the potatoes and cut them into bite-sized cubes.
In a large mixing bowl, combine sour cream and mayonnaise.
Add the cubed potatoes, shredded cheddar cheese, crumbled bacon, and chopped green onions to the bowl.
Gently fold the ingredients together until well-combined.
Season with salt and pepper to taste.
Transfer the salad to a serving dish and garnish with fresh parsley.
