Jackie's Loaded Baked Potato Soup

1 lb. bacon, diced
1 onion, diced
5 large Russet potatoes, peeled and cubed
3 c. chicken stock
3 T. butter
3 T. flour
1 1/2 c. milk
3 green onions, sliced
3/4 c. shredded cheddar cheese, divided
1/2 t. black pepper
Sour cream for garnish, optional

In a large stock pot, cook bacon until crisp. Remove with a slotted spoon to drain and set aside. Drain all but 2 T. of bacon grease from the pot. Cook the onions in the remaining bacon grease for about 5 minutes, until tender.
Add potatoes and chicken stock to pot. Bring to a boil, reduce heat to medium and simmer about 20 minutes, until potatoes are tender. With a slotted spoon, remove a few scoops of potatoes. Place in a bowl and mash with a fork. Set aside.
In a small sauce pan, melt butter. Stir in flour and cook for 2 minutes. Whisk in milk, bring to a boil and simmer until thickened. Slowly stir in to stock pot. Bring to a boil, reduce heat to low and simmer. Stir mashed potatoes back into pot.
Add 1/2 c. shredded cheese, three-fourths of the bacon and half the sliced green onions to pot. Add pepper. Stir to combine. Cook an additional 5 minutes.
At this point you can freeze or serve.
To serve, ladle soup into individual bowls and top with some shredded cheese, bacon, green onions and optional sour cream. If frozen, allow to thaw in fridge all day, then heat in microwave until warm.

Thanks to my Aunt Jackie for this awesome recipe!!
