Hot Spinach Dip

Direction :

Preheat oven; cook onion and garlic:
Preheat oven to 425°F. In a Dutch oven or large pot, heat oil over medium. Add onion and garlic; cook until lightly browned, 5 to 8 minutes.
Add spinach in two parts and wilt; drain:
Add spinach in two additions, letting the first batch wilt before adding the next; cook until completely wilted, 5 to 8 minutes. Transfer to a colander; drain, pressing to release all excess liquid.
Warm milk; add cream cheese:
In the same pot, warm milk over high heat. Whisk in cream cheese until melted, about 3 minutes.
Add spinach and remaining ingredients; transfer to baking dish:
Add spinach, Worcestershire sauce, hot sauce, and 1/4 cup mozzarella; stir to combine. Season with salt and pepper. Pour into a lightly oiled 1 1/2-quart shallow baking dish; sprinkle with remaining 1/2 cup mozzarella.
Bake:
Bake until bubbly and golden brown, 20 to 25 minutes. Serve hot with accompaniments, as desired.
