Restaurant Good Broccoli Cheddar Soup

I have tried and failed Broccoli Cheddar Soup before...too watery....too oniony...too unhealthy...but I now have the perfect soup!  The recipe came from allrecipes.com but I tweaked it:)

Serves 8

1 small yellow onion (diced)

1/4 cup butter

2 16-oz packages of frozen broccoli (thawed)

About 3 cups chicken broth

1 pound Velvetta (small block)

2 cups milk

1 tsp garlic powder

1/2 tsp red pepper flakes (optional)

1 tsp salt

1/2 cup cornstarch

3/4 cup water

In a Dutch oven or large stalk pan melt butter.  Add diced onions to melted butter and cook on medium until onions are soft. 

Roughly chop broccoli.  Add chopped broccoli to butter mixtures.  Pour chicken stock over until the broccoli and onions are covered.  Let cook on low to medium  heat until broccoli is soft (about 10-15 minutes).

Dice cheese into medium cubes.  Add cheese and stir until melted.  Add milk, garlic, salt and pepper flakes and stir in. 

In a small bowl mix cornstarch and water.  Stir into soup until thick.  Let simmer until ready to serve. 

If its too thick after simmering add a little more milk.
