Preheat your oven to 400°F (200°C). Wash the russet potatoes thoroughly and pat them dry. Using a sharp knife, make thin slices across each potato, being careful not to cut all the way through — keep slices connected at the bottom to create a fan effect.
In a small bowl, mix together the olive oil, garlic powder, onion powder, paprika, salt, and pepper. Generously brush this seasoning mixture all over the sliced potatoes, making sure to get in between each slice.
Place the seasoned potatoes on a baking sheet lined with parchment paper or foil for easy cleanup. Bake in the preheated oven for about 45 minutes, or until the potatoes are tender inside and crispy on the edges.
Remove the potatoes from the oven and sprinkle shredded cheddar cheese evenly over each potato. Top with chopped turkey bacon. Return to the oven and bake for an additional 5-7 minutes, until cheese is melted and bubbly.
Dollop each potato with sour cream and sprinkle with sliced green onions. Serve immediately and enjoy!
