I needed a side for Thanksgiving and found this on Thatsmyhome.com, although I've seen it at other sites. Sorry if this is a re-post, I can't remember if I already posted it.

I thought this came out great. It can be made ahead, and baked just before serving.

Spinach-Mushroom Casserole

3 tablespoon butter

2 cups light cream (1/2 & 1/2)

3 tablespoon grated onion

2 packages frozen spinach, thawed and drained

1 lb. chopped mushrooms

3 tablespoon grated Gruyere or Swiss cheese

3 tablespoon flour

2 teaspoon salt

1/4 teaspoon nutmeg

1/4 teaspoon white pepper

Heat oven to 325º F.

For the mushroom sauce, saute the onions and mushrooms in butter for 5 minutes. Blend in the flour, salt, pepper and nutmeg. Gradually add the cream, stirring to boiling point. Turn off heat and taste for seasoning.

In a buttered casserole, spread half of the spinach; cover with half of the mushroom sauce, then repeat. Sprinkle with the grated cheese. Set in pan of hot water. Bake for 40 minutes.

Yields: 6 servings
