Baked Potato Soup

Baked Potato Soup (Cooking Light)Ofcourse MY options were not light but it was what I had on hand from making other recipes
4 baking potatoes (about 2 1/2 pounds) I used about 8 white potatoes which are smaller so I cooked them for about 45 minutes
2/3 cup all-purpose flour (about 3 ounces)
6 cups 2% reduced-fat milk I used one cup of Heavy cream and Five cups Whole Milk
1 cup (4 ounces) reduced-fat shredded extrasharp cheddar cheese, divided
1 teaspoon salt
1/2 teaspoon freshly ground black pepper
1 cup reduced-fat sour cream I used regular sour cream
3/4 cup chopped green onions, divided
6 bacon slices, cooked and crumbled
Cracked black pepper (optional)
Preheat oven to 400°.
Pierce potatoes with a fork; bake at 400° for 1 hour or until tender. Cool. Peel potatoes; coarsely mash.
Lightly spoon flour into dry measuring cups; level with a knife. Place flour in a large Dutch oven; gradually add milk, stirring with a whisk until blended. Cook over medium heat until thick and bubbly (about 8 minutes). Add mashed potatoes, 3/4 cup cheese, salt, and 1/2 teaspoon pepper, stirring until cheese melts. Remove from heat.
Stir in sour cream and 1/2 cup onions. Cook over low heat 10 minutes or until thoroughly heated (do not boil). Ladle 1 1/2 cups soup into each of 8 bowls. Sprinkle each serving with 1 1/2 teaspoons cheese, 1 1/2 teaspoons onions, and about 1 tablespoon bacon. Garnish with cracked pepper, if desired.
