In my book this recipe is hands down the winner of my Christmas meals!! OH HOLY GOODNESS!! I wanted to eat this and not much else. I thought I had ruined it after I added the salt. It calls for a full Tablespoon. I put half of that in there and it was SALTY. But it sat in the fridge while we went to church on Christmas Eve. Then we came home and I baked it. VOILA. Not salty at all – just right! So try a teaspoon or a tsp and a half. You can always salt it on your plate after you serve it!
Also, we used plain swiss instead of Gruyere. Gruyere cost a fortune ($12 for a small square at my grocery store!) and maybe I’m cheap, but I went for swiss. It was still delish! This is a recipe I see getting repeated often.
PS: This seems to yield 12 (or more) servings, not 8.

Yield: 8 servings (but to me, more like 12+!)
4 tablespoons (1/2 stick) unsalted butter
4 cups chopped yellow onions (2 large)
1/4 cup flour
1/4 teaspoon grated nutmeg
1 cup heavy cream
2 cups milk
3 pounds frozen chopped spinach, defrosted (5 (10-ounce) packages)
1 cup freshly grated Parmesan cheese
1 tablespoon kosher salt
1/2 teaspoon freshly ground black pepper
1/2 cup grated Gruyere cheese
Preheat the oven to 425 degrees F.
Melt the butter in a heavy-bottomed saute pan over medium heat. Add the onions and saute until translucent, about 15 minutes. Add the flour and nutmeg and cook, stirring, for 2 more minutes. Add the cream and milk and cook until thickened. Squeeze as much liquid as possible from the spinach and add the spinach to the sauce. Add 1/2 cup of the Parmesan cheese and mix well. Season, to taste, with salt and pepper.
Transfer the spinach to a baking dish and sprinkle the remaining 1/2 cup Parmesan and the Gruyere on top. Bake for 20 minutes until hot and bubbly. Serve hot.
