2 teaspoons olive oil, plus more for baking dish 
1 onion, finely chopped 
2 garlic cloves, minced 
2 pounds spinach, washed well and coarsely chopped 
½ cup milk 
6 ounces cream cheese, cut into pieces, softened 
3 dashes Worcestershire sauce 
3 dashes hot-pepper sauce, such as Tabasco 
¾ cup shredded mozzarella cheese (3 ounces) 
Coarse salt and freshly ground pepper


1 Preheat oven to 425°F. Heat oil in a Dutch oven (or large pot) over medium. Add onion and garlic; cook, stirring occasionally, until lightly browned, 5 to 8 minutes. 

2 Add spinach in two additions, letting the first batch wilt before adding the next; cook until completely wilted, tossing frequently, 5 to 8 minutes.Transfer mixture to a colander; drain, pressing to release all excess liquid.

3 In the same pot, bring milk just to a simmer. Add cream cheese and cook, whisking, until melted, about 3 minutes. Add spinach, Worcestershire sauce, hot-pepper sauce, and ¼ cup mozzarella; stir to combine. Season with salt and pepper.Transfer mixture to a lightly oiled 1½-quart shallow baking dish; sprinkle evenly with remaining ½ cup mozzarella. 

4 Bake until bubbly and cheese is golden brown, 20 to 25 minutes. Serve hot.
