Low Carb Keto Green Bean Casserole

It might seem a bit early to be stressing out about Thanksgiving, but there is no time like the present.

Low carb Thanksgivings can be so dispiriting.  You're surrounding by tempting, yet carbohydrate filled classics.  Like green bean casserole.  Green beans should be an easy go-to food for low carbers.  But no!  Green bean casserole is just swimming in soup and fried onions.

Why must they sully the green beans like that?  Why?   

Well I am happy to report that my fretting has paid off.  I've pieced together a low carb version of green bean casserole that might actually be better than the original.  It has all the mushroomy goodness with less than half the carbs.
