Slice onions thinly and sauté lightly in butter, sauté until the onions become clear. Mix all together simmer till onion is tender but not too soft, this can take about 30 minutes or so. Sprinkle with Parmesan cheese and garlic croutons.
We have also tried cooking this soup on low in a crock pot and have had excellent results.
