Spinach and Gruyère Gratin

I actually used frozen spinach and it worked great. I used the organic frozen chopped spinach from Trader Joes, which is better than the frozen chopped spinach in the box. I plan on making it again with fat free half and half.

Just made this yesterday for Thanksgiving-I did fresh spinach which of course made more work for me but it was delicious! However, this is not a gratin, it's a quiche!

I'd like to lighten this up, fer Pete's sake! What do you think about 1% milk with, maybe half and half or evaporated low-fat milk instead of the heavy cream? Anyone know?

Would rather use FRESH spinach. Anyone try it with fresh instead of frozen?

Made this last night - wonderful! Rich and flavorful, lovely as a side dish or a main course

This was really good! I made it the day before Thanksgiving and heated it up in the oven before serving. My mom and I loved it - we are the spinach eaters in the family. I topped it with buttered bread crumbs and that was good too. Leftovers were awesome, and I've had requests to make it again. So now it is a standard Thanksgiving dish. :)
