This recipe was really good and a great replacement for the standard green bean casserole, which is filled with canned stuff. I prefer fresh and natural. I made this for thanksgiving and everyone liked it (except my sister and I) and everyone either said they didn't like green bean casserole or had never tried it. My sister and I did not like the ranch dressing mix flavor. I would like to try this again without the ranch dressing and using other seasonings. Thanks for sharing!

Loved this, although I did modify it a little. Left out the mushrooms entirely as DH doesn't eat them. Used a 28 ounce can of green beans and a whole package of ranch dressing. Nice change from the "usual" green bean casserole.
