6 slices bacon, diced
8 ounces cream cheese, at room temperature
1 cup sour cream
1/4 cup freshly grated Parmesan
2 tablespoons mayonnaise
1 tablespoon Worcestershire sauce
2 cups baby spinach, chopped
1 cup shredded mozzarella cheese, divided
1 cup shredded cheddar cheese, divided
Kosher salt and freshly ground black pepper, to taste
2 tablespoons chopped fresh parsley leaves
Heat a large skillet over medium high heat. Add bacon and cook until brown and crispy, about 6-8 minutes. Transfer to a paper towel-lined plate. Preheat oven to 400 degrees F. Lightly oil a 9-inch baking dish or coat with nonstick spray.
In a large bowl, combine cream cheese, sour cream, Parmesan, mayonnaise and Worcestershire. Stir in bacon, spinach, 1/2 cup mozzarella cheese and 1/2 cup cheddar cheese; season with salt and pepper, to taste.
Spread bacon mixture into the prepared baking dish; sprinkle with remaining 1/2 cup cheeses.
Place into oven and bake until bubbly and golden, about 20-25 minutes.
Serve immediately, garnished with bacon and parsley, if desired.
