Step 1

Preheat the oven to 375°F.

Step 2

Place the pepperoni on a paper towel lined plate. Microwave on high for 45 seconds. Blot the tops of pepperoni with a paper towel to remove excess oil. Set aside.

Step 3

In a medium bowl, stir to combine the cream cheese, 1/2 cup parmesan, and Italian seasoning. Spread the mixture in an even layer in a 9-inch deep-dish pie plate.

Step 4

Spread 1/2 cup marinara evenly over the cheese mixture. Sprinkle with 1 cup mozzarella, 1/2 cup parmesan, and 2 tablespoons each of pepperoni, black olives, bell pepper, and red onion. Repeat with the remaining marinara, mozzarella, parmesan, pepperoni, black olives, bell pepper, and red onion.

Step 5

Bake until the cheese is bubbling and beginning to brown, about 30 minutes.

Step 6

Increase the oven to broil and bake 2 minutes more. Let cool for 10 to 15 minutes before serving. Serve with toasted baguette slices.
