Preheat the oven to 375 F/190 C. Wash and dry the potatoes completely. Poke holes in each one with a fork.
Add the potatoes to a bowl and drizzle with oil and add a few pinches of kosher salt. Use your hands and make sure they are evenly coated.
Place the potatoes on a sheet pan lined with parchment paper or a silicone mat and bake for 1 hour or until soft when poked with a fork.
Allow the potatoes to cool for 15 minutes or so until they can be handled. Slice in half lengthwise and scoop out the inside with a spoon and place it in a bowl. Set the potato "boats" back on the sheet pan.
Add the butter, garlic powder, a pinch or two of salt, pepper, sour cream, half of the green onion, half of the bacon, and half of the cheese to the potato. Then mash all those together to create the filling. Taste and add more seasonings as desired.
Fill each potato "boat" evenly with the mixture. Sprinkle the remaining cheese on top and bake for 15 to 20 minutes until all the cheese is melted.
Remove them from the oven and top with the rest of the bacon and green onion. Enjoy!
