Pre-heat oven to 400 degrees, lay out the bacon on a parchment lined baking sheet. Bake in the oven for 20 minutes or until crispy. While bacon is cooking, scrub potatoes clean and slice into 1/2 inch rounds. Set crispy bacon aside, using paper towels to remove excess grease from the bacon. Reserve 2 tablespoons of the bacon fat from the pan.

Add potato rounds into a large bowl, add salt and pepper, pour in the bacon fat and toss potatoes well with coat evenly on all sides with seasonings and grease.

Reduce oven to 375 degrees. Place potato slices directly onto the baking sheet 1" apart. Bake in the oven for 20 minutes.

While potato slices are baking, shred 1 block of cheese, slice up the green onions and dice the bacon.

Remove potatoes from the oven, reduce heat to 350 degrees. Top each potato slice with 1 tablespoon of cheese followed by a big pinch of bacon. Bake for 8-10 minutes or until the cheese is fully melted.

Remove potatoes from the oven and add sliced green onions and a sprinkle of finishing salt. Serve with sour cream or ranch for dipping.
