Crockpot Bacon Cheese Potatoes

The recipe comes from Pinterest. Everything with bacon is good :)

1/4 pound bacon, diced, cooked
2 medium onions, sliced
4 medium potatoes, sliced
1/2 pound shredded cheddar cheese
salt and black pepper
butter
green onion

  Line crockpot with foil, leaving enough to cover the potatoes (this will help to not stick and to steam the potatoes)
  Layer half each of bacon, onions, potatoes and cheese in crockpot. Season to taste with salt and pepper and dot with butter.
  Repeat layers of bacon, onions, potatoes and cheese. Season to taste and dot with butter.
  Cover with remaining foil.
  Cover and cook on low for 10 hours (or on high for 4 hours).
