Rub potatoes thoroughly with olive oil and sprinkle them with salt. Place on a baking sheet or directly on oven rack and bake until tender, 45-60 minutes, turning over halfway through.

Step 3

Let cool until cool enough to handle, about 15 minutes and reduce oven temperature to 350°F.

Step 4

Cut potatoes into bite-sized pieces and place in a large bowl.

Step 5

Add sour cream and mayonnaise to bowl and stir to combine.

Step 6

Add 1 1/2 cups of the cheese, 3/4 of the green onion, and 3/4 of the bacon and stir to combine. Spread into prepared baking dish and top with remaining cheese and bacon.

Step 7

Cover dish with foil and bake for 20 minutes. Remove foil and bake until cheese is melted and bubbly, about 10 minutes more. Top with green onions and serve. Enjoy!
