1 pint heavy cream or half and half
2 c milk
1 c red onion, finely diced
2 T minced garlic

1 c carrots, grated
2 c chicken (cooked, diced)
1 package gnocchi, halved and cooked
1 T salt
1 t thyme
1 t parsley
1 T pepper

Sauté garlic and onion in oil and butter until onions are translucent. Add flour to make a roux.

Add milk and heavy cream.  Add chicken, carrots. Add chicken broth.  Cook until thick consistency you like.  Add gnocchi and spices.
