Creamed Spinach Gratin - cooking recipe

Ingredients

2 tablespoons unsalted butter (plus more for the dish)
1 garlic clove, halved
5 shallots, thinly sliced crosswise
5 (10 ounce) boxes frozen spinach, thawed
8 ounces cream cheese, at room temperature
1 cup heavy cream
1 cup whole milk
1 cup grated gruyere or 1 cup grated swiss cheese
1 teaspoon kosher salt
1/2 teaspoon black pepper
1 teaspoon ground nutmeg

Preparation

Heat oven to 375 degrees.
Rub the sides and bottom of a buttered 8-inch baking dish with the garlic; discard garlic.
In a skillet, over medium heat, melt the butter. Add the shallots and cook until softened, 5 to 7 minutes.
Squeeze the spinach to remove any excess liquid. In a large bowl, combine spinach, cream cheese, heavy cream, milk, Gruyere or Swiss cheese, salt, pepper, nutmeg and shallots. Transfer to dish.
Bake, uncovered, until bubbling and lightly golden, about 25 minutes.
