Good, straight forward side dish. However, the author of the recipe forgot to list the sour cream in the list of ingredients. Thanksgiving morning I was preparing my casserole and got to the part where I was supposed to add it. I substituted some extra broth to make up for it, but it still ended up dry and gooey. My advice, don't try anything new on a holiday.

I found I didn't have any cream of chicken or mushroom to make the traditional Hash Brown Casserole, so I found this recipe. I substituted 1/2 1% milk and 1/2 Half and Half for the milk, used low-fat instead of non-fat sour cream and added 1/2 cup chopped green pepper instead of 1/2 cup chopped onions. Regular cheddar as well. Very yummy...but a more fat than recipe...

This was really good, and great if you're on WW. It smelled great cooking in the oven and was easy to prepare. The only thing it needed was more seasoning, it was pretty bland as is. But overall a great recipe! :) Thanks!
