Homemade cream of chicken soup

With trying to eat healthy, I decided to try my hand at making soups for use as sauce for different dishes.  I am not a fan of cream of chicken soup on its own, but it is a great topping for chicken dishes. 

Recipe

Ingredients:
3 cups of Low sodium chicken stock,
2 cups of heavy cream,
1 cup of milk,
1 tsp of olive oil,
1 small onion finally chopped,
2 cloves of garlic, and
1 tsp of corn starch.

Directions
In a sauspan, heat the olive oil.  once heated till it shimmers; add in the onion and garlic.  Cook the onion and garlic until translucent.  slowly add the chicken stock.  For a smother result, add one cup of stock, and with a puree blender, puree the onions and garlic.  Ad the remainder of the stock, bringing it to a simmer.  Reduce by 1/4, then add in the cream slowly.  while string reduce by another 1/4.

The soup should be starting to thicken.  Make a corn starch slury with the milk, and corn starch, and add into the pot.  Let come to a simmer for a few min while string, and the soup should thicken.  At this point you can add optional cooked chicken chunks, or serve as is.
