Preheat oven to 350 degrees F. Spray a 2 quart baking dish or cast iron skillet with non-stick cooking spray and set aside.
Add cream cheese, mayo, sour cream, minced garlic, garlic powder and paprika to a large mixing bowl and stir until combined well.
Add spinach (make sure you've really pressed it to get all the excess water out!), cooked bacon, Parmesan cheese and 1 cup of the shredded Mozzarella cheese. Stir until mixed thoroughly.
Transfer mixture to prepared baking dish/skillet. Sprinkle with remaining ½ cup shredded Mozzarella cheese, then place thinly sliced fresh Mozzarella cheese on top of the dip. Drizzle lightly with olive oil.
Bake until cheese is golden and mixture is bubbly, about 30 minutes. If your dip is very full in the baking dish, place dish on a baking sheet in case it bubbles over.
Sprinkle dip with minced fresh parsley.
Line sliced baguette pieces on a baking sheet and drizzle lightly with olive oil. Broil on HIGH for several minutes per side, until golden brown and toasted. Be careful, bread can burn VERY quickly this way.
Serve dip hot, with toasted baguette pieces alongside.
