Ingredients
- 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
Directions
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.

This spinach gratin is creamy, cheesy, baked goodness. Great side dish that is especially good for Christmas/Holiday entertaining. I have made this a day ahead then I just take it out of the refrigerator, let it come up to room temp, then bake as directed.
I use a standard (9x11 or 9x13 clear, glass baking dish and it has worked for me every time.

This was wonderful at Christmas dinner - but I wonder if I should have used a gratin dish?
The taste was unbelievably good but I thought I got the texture was off. I used a pie dish and maybe it should have been spread thinner into a gratin dish? Thoughts?
