Baked Potato Soup

(credit to Kellie)

INGREDIENTS
2/3 cup butter
2/3 cup flour
7 cups 2% milk
4 large potatoes, baked, peeled, and cubed (I "bake" them in the microwave)
4 green onions, sliced
6 strips bacon, cooked and crumbled
1 cup sour cream
¾ teaspoon salt
½ teaspoon pepper
3/4 cup shredded cheddar cheese
3/4 cup shredded sharp cheddar

DIRECTIONS
Heat butter in large sauce pan. Add flour and whisk until smooth. Add milk and stir until thickened. Be sure to stir constantly and scrape the bottom of the pan, or the milk will burn. Then add potatoes and onion. Bring to a boil, stirring constantly. Reduce heat and simmer for 10 minutes. Add bacon, sour cream, salt and pepper. Add cheese just before serving. Can be served in bread bowls.
