Baked Potato Soup - a lighter version

I love when I find recipes that allow me to substitute full fat ingredients for reduced fat or reduced calorie. I love baked potato soup but because of the heavy creamy texture I don't make it very often. I found this recipe on Our Best Bites, one of my favorite blogs. It uses skim milk instead of whole, and light sour cream and you get very similar results...a very tasty soup.

Baked Potato Soup

2 Tbs butter
2-3 cloves garlic, minced
1/2 C flour
4 1/2 C low-fat or skim milk
1 14oz can chicken broth
4 medium baking potatoes (about 2 1/2 pounds) baked*
2 C grated cheddar (or sharp cheddar) cheese, divided
1 1/2 tsp. salt
1/2 tsp. black pepper
1 1/2 C  light sour cream, divided
1/2 C chopped green onions, divided
8 slices bacon, cooked and crumbled, divided

*don't have time to bake potatoes in the oven?  Just pierce them with a fork a few times and then pop them in the microwave.  Cook in 5 minute intervals until a knife easily pierces through them.  It usually takes 5-10 minutes.  To bake in the oven, pierce each potato with a fork and place directly on oven rack.  Bake at 375 for 45-60 minutes.

Melt butter in a stock pot over medium heat.  Add garlic and saute for 30-60 seconds until fragrant.  Add flour to pan.  Slowly add milk a little at a time while whisking constantly to eliminate lumps.  Whisk until smooth and then add chicken broth.  Bring soup just to a simmer and heat until thickened, stirring often, about 5 minutes.

Once soup is thickened, turn heat down to medium-low.  Cut potatoes in half length-wise and use a spoon to scoop out potato flesh into the pot.  Use a wooden spoon to smash potatoes, breaking up large clumps.  Add 1 1/2 C grated cheese and salt and pepper and stir until cheese is melted.  Remove pan from heat and stir in 3/4 C sour cream, 1/4 C green onions, and 4 strips of the crumbled bacon.  Add additional salt and pepper to taste. Ladle into bowls and top with each serving with the remaining sour cream, onions, cheese, and bacon.
