01 - Preheat the oven to 375°F. Grease a 9-inch round baking dish or similar oven-safe dish with cooking spray or butter.
02 - In a large bowl, combine the cream cheese, sour cream, cheddar, Monterey Jack, Parmesan, jalapeños, garlic, smoked paprika, salt, and black pepper. Mix thoroughly until all ingredients are evenly incorporated and smooth.
03 - Spread the cheese mixture evenly into the prepared baking dish, using a spatula to create a smooth surface.
04 - In a small bowl, combine Panko breadcrumbs, Parmesan cheese, and melted butter. Stir until the breadcrumbs are evenly coated with butter.
05 - Sprinkle the crumb 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 oven and let cool for 5 minutes to set. Garnish with chopped fresh parsley if desired. Serve warm with tortilla chips, crackers, or sliced baguette.
