01 - Preheat the oven to 375°F. Grease a 9-inch round baking dish or similar oven-safe dish with butter or cooking spray.
02 - In a large bowl, combine the cream cheese, sour cream, cheddar, Monterey Jack, Parmesan, jalapeños, garlic, smoked paprika, salt, and black pepper. Mix until thoroughly incorporated and smooth.
03 - Transfer the cheese mixture to the prepared baking dish and spread evenly using a spatula, ensuring a smooth surface.
04 - In a small bowl, combine Panko breadcrumbs, Parmesan cheese, and melted butter. Stir until the butter evenly coats the crumbs.
05 - Sprinkle the breadcrumb mixture evenly over the dip. Bake for 20-25 minutes until the dip is bubbly around the edges and the topping is golden brown.
06 - Remove from the oven and let cool for 5 minutes to set. Garnish with chopped parsley if desired. Serve warm with tortilla chips, crackers, or sliced baguette.
