Made some adjustments. Added 1.5c diced celery and upped the butter to 4 Tbsp. Used heavy cream instead of half and half. Added 2c shredded sharp cheddar and 2c shredded NY sharp white cheddar cheese. Made in crockpot. 3hr on high. Then on low 4hrs more. Added cheese in last hour. Also Added onion powder, garlic powder, and paprika, and salted to taste. Delicious.
