Creamy Baked Spinach

• 4 tablespoons butter
• 2 large onions, chopped
• 14 cup flour
• 14 teaspoon grated nutmeg
• 1 cup heavy cream
• 2 cups milk
• 2 eggs, lightly beaten
• 3 lbs frozen chopped spinach, defrosted (5 10-ounce packages)
• 12 teaspoon kosher salt
• 12 teaspoon fresh ground black pepper
• 1 cup freshly grated parmesan cheese
• 1 cup grated gruyere cheese
• 1 cup grated cheddar cheese
• 12 cup crumbled feta cheese
• 13 cup breadcrumbs

1. Preheat the oven to 425 degrees F.
2. 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; cool 10 minutes then quickly beat in the eggs.
3. Squeeze as much liquid as possible from the spinach and add the spinach to the sauce; add 1/2 cup each of the Parmesan, Gruyere and cheddar cheeses and all of the feta and mix well; season, to taste, with salt and pepper (you may need little to no salt).
4. Transfer the spinach to a buttered 13 x 9 inch glass baking dish; toss the remaining cheeses with the breadcrumbs and sprinkle on top.
5. Bake for 20-25 minutes, until hot and bubbly; serve hot.
6. Note: This dish can be made one or two days ahead and refrigerated, unbaked, then baked right before serving; bring to room temp before baking.
