Best Baked Potato Soup Ever

1-2 lbs. Bacon ( I used half turkey bacon and half regular bacon.)
2/3 cups butter
2/3 cups flour
5 cups milk
2 cups chicken broth
4-8 potatoes-baked, peeled and cubed (I cubed half and mashed a little the rest.)
4 green onions--chopped
1/4 regular onion-chopped
1 garlic clove-minced (optional--but very good.)
1 1/4 cup shredded chedder cheese (grate some extra for the garnish.)
1 cup sour cream
1 tsp. salt
1 tsp. black pepper
*Cook bacon, melt butter, add onions and garlic, saute. Add flour. Stir milk and chicken broth together and add to mixture--wisk until thick and almost to boil. Put in potatoes--wisk until boiling. Reduce heat, sour cream, salt, and pepper. Cheese and bacon. So yummy!! Hope you all like it too.
