Definitely worth making and qualifies as comfort food. I used 1% milk instead of skim. Doubled the recipe and it came out great. Thought I had nutmeg on hand, but didn't and it was still delicious.
Green Bean Casserole with Caramelized Onions
From EatingWell: March/April 1992
This is not the no-mess, super-easy recipe of yore, but it is low in fat and high in flavor. To go one step further, substitute 1/2 pound fresh green beans for frozen. Simply trim and cut into 1-inch lengths. Then blanch the beans for 1 to 2 minutes in boiling water, refresh under cold water and spread in the baking dish.
