In a large soup pot, sauté onion and celery in butter until onion is translucent, about 5 minutes.
Add the chicken broth, potatoes, salt, pepper, garlic, and parsley and simmer for 30 minutes.
Add the corn and simmer gently for another 15 minutes or so.
Add the half-and-half and milk and heat thoroughly but do not boil.
Adjust seasonings and serve.
Notes / Tips / Wine Advice:
Many times I’ve decided on corn chowder for dinner and simply used frozen corn if I didn’t have time to thaw it beforehand. The soup is just as good, but taste several kernels to be certain the corn has been completely cooked before adding the half-and-half and milk.
